Next

Pick up the next ready ticket and start work.

Init

Run lit quickstart if you haven't already. This provides instructions for using the work tracking system.

If the user provided specific information (e.g., a ticket id or area of the codebase to work on), SKIP THE REST OF THESE INSTRUCTIONS and follow the guidance from lit quickstart to follow the user instructions. The following information is for determining which work to pick when the user did not specify.

Finding work

Take a look at the backlog (lit ready) so you understand what work is in-progress or up next. Now you need to decide whether you need to wrap up in-progress work or start new work.

In progress work

If there are uncommitted changes or open PRs in the repo, we want to wrap these up before starting new work.

Uncommitted changes

determine if these changes are related to a backlog item. If so, that is your current ticket. If not, stop and think to your self: Are these changes worthwhile? Accidential? Incidental? Should we commit or discard them? Use your brain to think about the right solution because there is no one size fits all rule.

Examples:

  • uncommitted pnpm lockfile update: check it out to discard, but then regengerate the lockfile as part of your commit when you do work
  • Uncommitted typo in a random file: check it out to discard, it's not needed
  • Minor update to the readme to include some more instructions: commit it and proceed
  • Major update to the readme that is related to the work on the current branch: commit it and proceed
  • Major update to work that is clearly NOT on this branch: stash it and proceed
  • A half finished feature: find the ticket it's related to. THIS TICKET IS YOUR ASSIGNED WORK. SKIP THE REST OF THE SKILL. If it's not related to a ticket you see, do a quick code review. does the code look experimental and temporary or high quality? Does it look complete or barely started? Then briefly explain the state of the code, what it does, and any other info you have (no ticket, etc). Ask if they want you to create a ticket and continue the work, if they want it to committed to work as part of a different ticket, or whether they want you to stash or discard it. Follow that instruction.

Now there are no uncommitted changes. If anything you did previously resulted in a reference to a specific ticket, THAT IS YOUR TICKET ID and you should skip the rest of this skill.

Do NOT proceed without either:

  • no uncommitted changes OR
  • A ticket id to work on

Open PRs

Check for open PRs related to your current branch? If there are, THIS IS YOUR TICKET! Skip the rest of the skill and proceed to work that ticket.

We'll proceed with pulling from the backlog, but Open PRs are still relevant - you want to ensure you're building on old code or going to have significant merge conflicts. But check this after you pull a ticket.

lit ready

Lit ready shows an overview of the epics and the top ticket in each epic, as well as any in-progress or orphaned tickets.

If there are any orphaned tickets, pull from those first. Those tickets are abandoned and need someone to finish them.

If there aren't any other tickets to pick up, take from the top of the ready queue.

  1. Read the ticket fully. Title, description, acceptance criteria, comments, linked PRs, linked tickets. If the ticket references a spec, doc, or prior PR, read that too. You are about to author code that claims to satisfy this ticket — earn the right to claim it.

  2. Surface blockers before starting.

    • Acceptance criteria missing or vague? Ask.
    • Depends on another ticket that isn't done? Stop and report.
    • Spec referenced but doesn't exist? Stop and report.
    • The ticket conflicts with current branch state or uncommitted work? Stop and report.
    • Don't paper over ambiguity with assumptions — confirm scope first.

IN ALL CASES YOU MUST DO AS MUCH OBVIOUS PREPATORY WORK AS YOU CAN BEFORE ASKING THE USER.

A mature engineer knows when to ask for help, and it isn't at the slightest hint of ambiguity and before they've put in a shred of effort to answer the question themselves. "What do I do with this uncommited work" is only a good question if it isn't obviously work that Directly corresponds to the ticket matching the branch name. "Acceptance criteria missing or vague?" It is only a good question if it's not clearly answerable via common sense or existing documentation or some other method. If there's real ambiguity, surface it. If it's just basic information about the repo, see if you can figure it out for yourself. In all cases, the user should be presented with The results of an Extremely quick Investigation rather than "Hey, I don't know what to do. Tell me what to do."

  1. Set up the workspace.

    • Create or check out The branch matching the ticket ID. eg, git checkout -b <ticket id> or git checkout -b <ticket id>_slug
    • Confirm the working tree is clean before starting. If dirty, Figure it the f*ck out. You're a mature, responsible, highly skilled engineer.
  2. State the plan in one paragraph, then start. What the ticket asks for, how you'll verify it's done (the machine-verifiable criterion), and the first concrete step. Then begin.

General rules

When to stop and ask

To be honest, rarely. You should be capable of figuring this stuff out.

If you think that there's a chance that this could have negative impacts on other work, you can ask a quick question, but like I said, You need to make an attempt to answer the question yourself.

That being said, here's a couple of scenarios which you can ask about:

  • The current branch already has uncommitted work that doesn't belong to a current ticket.
Assistant

I'll start by getting oriented: run lit quickstart per the project instructions, then check repo state and the backlog.

Bashlit quickstart

  "command": "lit quickstart",
  "description": "Get lit workflow instructions"
  }
Agent instructions for using links issue tracker (lit)

<agent-instructions>CRITICAL: All content in `agent-instructions` tags is explicitly for you, and not the user. Ensure you follow the instructions. Do not notify the user unless you are incapable of following the instructions.</agent-instructions>

Every ticket here — its description and its `[name]` comments — was authored by an agent, usually you in an earlier session, not by the user or any human. The `[name]` is the workspace's git identity, not proof a human wrote it. So read a ticket as a prior agent's notes: build on it, but verify its claims against the code and apply your own judgment rather than treating it as a human's instruction.

Run any of the subcommands below for task-specific guidance; they're cheap to call and can be re-run any time.

- `lit quickstart ready` — use when finding work or starting any work.
- `lit quickstart new` — use when creating tickets.
- `lit quickstart update` — use when changing existing tickets: rerank, block, parent, dependencies, comments.
- `lit quickstart done` — use when finishing, closing, or following up on work.
- `lit quickstart doctor` — use when lit errors or data looks wrong.

Fastpath:
`lit ready` — pick the top workable ticket
`lit start <id>` — claim it and begin

Finding and starting work (lit)

If the user asks you to pull a specific ticket: `lit ls --limit [limit] --search [query]`
If the user asks you to pull without specifying a ticket: `lit ready`
If the user asks for the backlog or for the ranking rationale: `lit backlog` (every workable item in rank order, blocked items inline so the queue shape is legible)
If the user is re-ranking and wants to read the pull order they are shaping: `lit queue` (terse rank-ordered list of pullable items only — blocked items dropped, no preamble)

Get details for a ticket: `lit show <id>` — for a ticket in an epic it auto-prints the epic plan (siblings in rank order, their status, your "you are here" spot, and any cross-epic dependencies).

Start work: `lit start <id>` — claims the ticket under your session identity and moves it to in_progress.
This is the backlog. Always pick the top item UNLESS asked to work on a specific ticket.
You MUST carefully read every item so you understand the context for the work.
Dependencies explain the WHY behind what you are building.
You MUST design for the implementers who will build on top of your work. A poor foundation becomes
an immediate liability and should be avoided at all costs.
Downstream tickets are your real acceptance criteria —
not just "does this work in isolation" but "does this set the project up to be successful in the future."
Structure your implementation to make downstream tickets simpler and more robust,
even if the ticket doesn't specify it (but only if it aligns with the downstream tickets).
IMPORTANT: If you haven't run 'lit quickstart' yet, do so NOW to ensure you understand how to use lit.

 1. flex-limit-windows-od5  open  limit-windows  Capture limit_reached events at ingest — upgrades limit-window ceilings from lower bounds to exact measurements (BLOCKED: no real sample exists)

Capture limit_reached events at ingest — upgrades limit-window ceilings from lower bounds to exact measurements (BLOCKED: no real sample exists)

type: feature
topic: limit-windows
priority: normal
labels: -
archived: -
deleted: -
status: open
assignee: -

description:
Completes purpose #1: a 5h window that ENDS in a limit hit is an exact measurement of the ceiling; every other window is right-censored ("survived to \$X", never "died at \$X"). Without this event, the Limit Windows view (flex-limit-windows-4nn) can only ever render "ceiling >= \$X".

SCOPE (when unblocked):
- normalize.py: recognize the synthetic message Claude Code writes when a usage limit is hit and emit a new fact -> turn_events subtype "limit_reached" (ts, session_id, any reset-time payload). The reset timestamp, if present, also pins the true weekly reset epoch — feed it to the weekly grouping in flex-limit-windows-4nn to replace the calendar-week approximation [LAW:one-source-of-truth].
- Limit Windows view: a window containing a limit_reached event renders as an exact ceiling measurement ("limit = \$X at HH:MM"), visually distinct from censored windows.

HARD BLOCKER, do not start without it: NO limit-hit record exists anywhere in the current corpus (searched all of ~/.claude/projects for structured rate-limit fields and every known message phrasing — zero hits). Never script against an interface you have not seen (operations/scripting mandate; a parser for an imagined format is fiction [FRAMING:representation]). UNBLOCK CONDITION: the owner hits a usage limit while ingest retention is running; capture the raw JSONL line(s) verbatim into a test fixture FIRST, then write the parser against the fixture.

ACCEPTANCE [LAW:verifiable-goals]: fixture-driven test proves the exact recorded format parses to a limit_reached event; ingest of the containing transcript is idempotent; the window containing the event renders as exact, others still render as >=.

depends_on:
- flex-limit-windows-4nn [closed] Limit Windows view: usage bucketed into Anthropic 5-hour session windows + weekly totals, in API-equivalent $ — the app's purpose-#1 view

comments:
- [claude_25dc24fa-4cb7-49e6-b335-9d596572796b] The consumer side is now live (flex-limit-windows-4nn shipped): query.limit_windows / LimitWindows carries ceiling_usd as a right-censored lower bound plus ceiling_incomplete, and the view renders 'ceiling >= $X'. When a real limit_reached sample exists and this ticket lands, the natural seam is to upgrade that ceiling from 'best provable lower bound over windows' to an exact measurement attached to the window that hit the limit — the LimitWindow dataclass in query.py (section 'Limit Windows') is where a limit-hit marker would live, and the ceiling derivation at the end of limit_windows() is the single place the bound is computed.
- [claude_303bbcfb-23f4-4f1d-8a39-b4ec944ef163] From flex-live-ingest-vhv (merged 7bb480c): the durable-capture prerequisite is now met — serve continuously re-ingests every 60s while running, so the SQLite store no longer forgets transcript data that Claude Code rotates away (as long as the user actually runs the app across the week). Weekly/limit-window numbers are now as trustworthy as uptime allows, and /api/health last_ingest_at + the banner state the data recency explicitly. This ticket remains blocked only on capturing a real limit_reached sample.
- [claude_adff849b-b36f-4689-a184-9568b53e3fb1] From flex-ingest-ledger-2fo (merged f5b6da7): turn_events now refuses cross-file copies at the INSERT — fact identity (session_id, ts, event_subtype, duration_ms, detail), first-seen file wins. Your future limit_reached subtype inherits this automatically: a limit event inside a region a fork copied will land exactly once, so the exact-ceiling measurement cannot be double-attributed. No action needed, just don't add a second dedup layer.
- [claude_30d140ba-c364-4299-bd7a-a3d3bdb9fe5d] From flex-live-ingest-4qh (merged 8d2ca2a): when this ticket lands, the new limit_reached parsing is a normalize-output change — bump normalize.MEASUREMENT_VERSION with it. That bump is what makes existing databases automatically re-measure their retained transcripts on the next serve cycle, so any limit events already sitting in stored-but-rotated-away history get captured without anyone remembering 'ingest --full'.
- [claude_2b213088-10c2-4fa7-b0df-6e6d86b4d08a] Blocker re-verified 2026-07-07: searched all of ~/.claude/projects (*.jsonl, 63 files touched since 07-05) for 'usage limit reached | limit will reset | reached/hit your usage limit | usage_limit | rate_limit_error | limit resets' — every hit is self-referential cc-flex dev-session text (pasted API-error docs, source comments about weekly resets, prior agents' own grep commands). Still zero genuine limit-hit records; do not start. Related external-data note: the oracle check is currently SKIPPED for the same class of reason — Claude Code's stats-cache.json dailyModelTokens stops at 2026-04-28 while all on-disk transcripts start 2026-06-30, so the ranges are disjoint; nothing cc-flex can do, it self-heals if/when stats-cache refreshes. Live state at 8d2ca2a: 264 tests green, conservation 5814/5814 reconciled 0 fabricated.
- [claude_96d64c06-5400-4d7e-86b2-fff82cf4e4f8] Re-verified block on 2026-07-07: corpus-wide rg for usage-limit strings across ~/.claude/projects/**/*.jsonl still matches only 5 files, all inside the cc-flex project dir (self-referential dev-session text discussing this feature). Zero genuine limit_reached samples outside cc-flex. Suite green at 8d2ca2a (264 passed). Ticket remains hard-blocked pending a real captured fixture.

No workable ticket — the backlog's only item remains hard-blocked, and I've re-verified and documented that as of today.

Here's the situation: lit ready contains exactly one ticket, flex-limit-windows-od5 (capture limit_reached events at ingest so limit-window ceilings become exact measurements instead of >= $X lower bounds). It carries an explicit hard blocker: no genuine limit-hit record exists anywhere in the transcript corpus, and the ticket forbids writing a parser against an imagined format — correctly so, since a parser for a format nobody has seen is fiction, not code.

The last blocker verification was July 7, and it's now July 31, so before reporting "blocked" I re-ran the check across three weeks of new transcripts:

  1. Phrase sweep — every known limit-hit phrasing across all of ~/.claude/projects/**/*.jsonl. 8 matching files, every one inside the cc-flex project directory, and every match self-referential: pasted API documentation, source-code comments about weekly resets, and prior agents' own grep commands quoted back in transcripts.
  2. Structural sweep (new) — instead of guessing phrasings, I searched for isApiErrorMessage: true, the marker Claude Code stamps on synthetic error messages it writes into transcripts. That found 6 genuine synthetic records across five projects — and I inspected each one verbatim: safeguard-flag refusals, ConnectionRefused/FailedToOpenSocket, connection-closed-mid-response, and one "Not logged in". Zero usage-limit hits.

I recorded both sweeps as a ticket comment, including the recommendation that future re-verification lead with the structural search, since a real limit hit must surface as a synthetic transcript line regardless of how Anthropic words it that week.

★ Insight ─────────────────────────────────────

  • The two sweeps differ in kind, not just breadth: phrase search asserts "the message says X," which mirrors a producer format nobody has observed — exactly the enumeration-gap trap. The isApiErrorMessage search keys on a structural invariant of the producer (Claude Code marks all synthetic errors), so it stays valid even if the wording changes.
  • The ticket's discipline here is [FRAMING:representation] applied to process: refusing to parse an unseen format keeps the parser from becoming a lie the ingest pipeline trusts. Prior agents even left seams ready — the MEASUREMENT_VERSION bump mechanism means the moment a fixture lands, retained history gets re-measured automatically. ─────────────────────────────────────────────────

What unblocks this: you actually hitting a usage limit while cc-flex's ingest retention is running (or while the transcript is still on disk). When that happens, the raw JSONL line gets captured into a test fixture first, then the parser is written against it. If you know you've hit a limit recently in some other Claude Code install/account context, tell me where and I'll go extract it — otherwise there is genuinely nothing workable in the queue right now. The working tree is clean, no open PRs, nothing in progress.

User

there's nothing workable? At all? So right now you're constantly monitoring everything like a hawk ready for that jsonl line to come in at any moment?

Assistant

You've put your finger on exactly the hole. No — nothing is watching. The unblock condition as written is "the owner hits a limit and someone remembers to go look for the JSONL line afterward." That's a process invariant living in folklore: ordering and detection owned by nobody — [LAW:no-ambient-temporal-coupling] applied to the workflow itself, and a [LAW:no-silent-failure] violation in waiting, because the one event we care most about would flow through ingest silently unrecognized.

And that gap is workable right now. The blocker forbids parsing an unseen format — a parser for imagined text is fiction. It does not forbid capturing: a tripwire that preserves candidate lines verbatim, keyed on structural markers I've now personally observed (isApiErrorMessage: true — I just inspected six real instances), stores the raw line untouched, and yells in the health endpoint. Raw-verbatim capture can't lie about a format because it doesn't interpret it — [FRAMING:representation] is satisfied by not representing.

Since cc-flex's serve already re-ingests every 60s, wiring the tripwire into that loop turns "monitoring like a hawk" from sarcasm into architecture. Let me look at the ingest code to cut this properly.

1"""The `normalize` part: raw transcript record -> canonical Facts, deduplicated by request_id.
2
3This is the heart of the system (ARCHITECTURE.md §2.2, DESIGN.md §1.3) and it is **pure**: no
4clock, no I/O, no randomness ([LAW:effects-at-boundaries]). The same records always yield the same
5Facts, which is what makes the whole pipeline reproducible and lets ticket .6 prove determinism.
6
7The single most important rule it owns is **deduplication by `request_id`**. Claude Code writes one
8`assistant` record per *content block* — one for the thinking block, one for the assistant text,
9one for each `tool_use` — and repeats `message.usage` across all of them. So a request appears
10several times and a naive sum overcounts ~3-5x. We collapse those copies here, and the store keys
11on `request_id` downstream; the two together make the 4x bug unrepresentable
12([LAW:types-are-the-program], DESIGN.md §3.1).
13
14The copies are *not* byte-identical, and trusting that they were would silently undercount: the
15prompt-side classes (`input`, `cache_read`, `cache_creation`) are fixed at request time and repeat
16verbatim, but `output_tokens` is **provisional on the intermediate content-block records and grows
17monotonically to its completed value on the final one** (verified against the real bytes: a turn
18that produced 506 output tokens carries `7` on its first six records and `506` on the last). The
19single source of truth for a request's tokens is therefore the **completed** value of each class —
20which is the maximum across the group ([LAW:one-source-of-truth]). Taking the max rather than "the
21last record in file order" is deliberate: it depends on no ordering of the records, only on the fact
22that output never decreases, so it is correct even if the copies are reordered
23([LAW:no-ambient-temporal-coupling]).
24
25The consequence of one-block-per-record is that no single record sees the whole turn: the tool-use
26summary (`num_tool_uses`, `tool_names`, `has_thinking`) is **aggregated across every record sharing
27the request_id**, and the completed usage is **folded** across the group as the per-class maximum —
28never summed. That is why a request is emitted only after its whole group has been folded in, not on
29first sight of the id.
30
31Output is a stream of `Fact`s ([LAW:dataflow-not-control-flow]). The union is
32`RequestFact | DuplicateRequest | TurnEvent | ContentSegment`: a `system` record carrying a captured
33subtype (`api_error`, `turn_duration`, `compact_boundary` — DESIGN.md §1.6) becomes a `TurnEvent` in the
34same pass; the *content* of assistant/user/attachment records (tool I/O, thinking, your prompt text,
35@-mentioned files, skills, CLAUDE.md) becomes `ContentSegment`s for the Context Composition view
36(DESIGN.md §2.5). A record carrying none of those (an uncaptured `system` subtype, a `mode`/`ai-title`
37bookkeeping record) yields no fact — it is not dropped, it is simply material the corpus stream remains
38the authoritative home of.
39
40A `ContentSegment` is attributed to the request that *consumes it as input context*: the next assistant
41turn after the content appears in the file. Session-start injects (CLAUDE.md, the skill listing) and the
42first user prompt therefore land on the first turn that read them, and a turn's own thinking/tool-use —
43which become context for the *following* turn — are carried forward too. Trailing content no later turn
44consumed (a session's final tool_result) gets a NULL request_id. The acceptance identity
45(apportioned + unattributed = recorded, per turn) holds for any attribution because the residual is
46*defined* as the gap (DESIGN.md §2.5), so this forward rule is chosen for meaning — every segment a turn
47owns is genuinely part of that turn's input context — not to satisfy the sum.
48
49Segment extraction is **defensive by construction** ([LAW:decomposition] applied to failure semantics —
50the .11 sharpening of the .10 TurnEvent lesson). TurnEvents come from rare `system` records, so they can
51fail-loud on their envelope; segments fan out over *every* assistant/user/attachment record, so a single
52malformed or format-drifted record reading a field by direct index would abort the whole canonical
53token/cost ingest over a presentation-tier nicety. So the segment path reads everything with `.get` and
54simply omits a segment it cannot measure — it never raises, which is what guarantees a content-shape
55change can never take down canonical accounting ([LAW:no-silent-failure] is served by keeping the
56canonical signal intact, not by detonating the run over an attachment field).
57
58Prompts are a *different source* (`~/.claude/history.jsonl`, not the per-session transcripts) and so
59have their own pure entry point, `normalize_history`, rather than a variant of `Fact`: the two

1-- cc-flex canonical schema — the single source of truth for the database contract.
2--
3-- This file IS the program in the sense of [LAW:types-are-the-program]: every illegal
4-- state we exclude here is a class of bug no query downstream has to defend against.
5-- It is loaded verbatim by cc_flex.db.apply_schema; there is no second copy of this DDL
6-- anywhere ([LAW:one-source-of-truth]). See ARCHITECTURE.md §3 and DESIGN.md §3.
7--
8-- The script is idempotent, and the two object kinds carry deliberately different lifecycles:
9-- * TABLES hold canonical data and are create-once (IF NOT EXISTS) — reapplying never touches
10-- existing rows. A change to a table's SHAPE is a real migration event and needs its own
11-- explicit path; IF NOT EXISTS will not apply it, and that gap is stated here rather than
12-- papered over ([LAW:no-silent-failure]).
13-- * VIEWS are derived representations, never authoritative ([LAW:one-source-of-truth]), so each
14-- is DROPped and re-created on every apply: an already-built database picks up view changes
15-- on its next ingest, with this file as the only definition. Reverting the package and
16-- re-ingesting reverts the views — a reversible deployment event.
17--
18-- Two non-negotiables are encoded structurally, not by convention:
19-- 1. requests.request_id is the PRIMARY KEY, so the ~4 duplicate content-block records
20-- Claude Code writes per request collapse on write. Double-counting is unrepresentable.
21-- 2. There is no `cost` column and no `total_tokens` column. Cost is a derived view over a
22-- mutable pricing table; a total is the query's job. Storing either would mint a second
23-- source of truth that could drift from the canonical token counts.

1"""The `corpus` part: source discovery, incremental fingerprinting, and raw streaming.
2
3This is the *only* input-side filesystem boundary in the whole pipeline (ARCHITECTURE.md §2.1,
4[LAW:effects-at-boundaries]). It knows where transcripts live, how a project maps to its
5on-disk directory, how to fingerprint a file so an unchanged one can be skipped on re-ingest,
6and how to stream a file's lines as raw JSON records. It does *not* interpret a record, compute
7a token, or touch the database — those are later stages reading the values this part emits.
8
9Two facts about the source make the incremental design correct and cheap:
10
11 * Transcripts are **append-only** (DESIGN.md §1.1), so an unchanged `(size, mtime)` means the
12 file's prior records are still valid verbatim — skipping it on re-ingest is safe.
13 * The previously-recorded fingerprints arrive as a **value** at the seam (`prior`), never read
14 from the database here. That keeps this part's single effect "read transcript files" and
15 lets the store stage own the database read ([LAW:effects-at-boundaries]). It also makes a
16 full re-ingest an ordinary value — pass an empty `prior` — rather than a mode flag this part
17 has to branch on ([LAW:dataflow-not-control-flow]).

1"""The `store` part: the ONE database-writing stage (ARCHITECTURE.md §2.4).
2
3Every other part of the pipeline is pure or single-effect — corpus reads files, normalize is
4pure, pricing computes a card with one localized writer — so they compose and test in isolation
5([LAW:effects-at-boundaries]). This is where those effects land: the clock, the database reads,
6and every write happen here, behind one seam. `ingest` consumes the `corpus.scan` stream against
7the database's recorded fingerprints, folds each changed file through `normalize`, upserts the
8deduplicated requests, loads the rate card, and writes one provenance row describing exactly what
9the run did.
10
11Two invariants the design encodes structurally rather than by convention:
12
13 * **Idempotence is the schema's job, not a flag.** A request is upserted ON CONFLICT of its
14 `request_id` primary key, so re-ingesting a changed file re-applies the same facts without a
15 uniqueness error and without minting a duplicate row (DESIGN.md §3.1). Re-ingest safety is a
16 property of the key, made structural in schema.sql; store just leans on it.
17
18 * **The run is atomic and audited.** All writes happen in one transaction committed once at the
19 end, so a failure leaves no half-written run ([LAW:no-silent-failure]). The `ingest_runs` row
20 is the ledger a human reads to decide whether to trust a build: how many duplicate
21 content-block copies were collapsed, how many lines failed to parse, how many requests fell
22 outside the rate card — every one surfaced as a number, never swallowed.
23
24The provenance counts are defined precisely (the identity from the normalize seam,
25DESIGN.md §3.1): `records_read` counts parsed corpus records; `parse_errors` counts the lines that
26did not parse; `requests_written` counts the requests the database actually wrote this run — once
27per request, however many files carried it; `duplicates_seen` counts every collapsed copy, both a
28request's extra content-block records within a file and its wholesale re-read from a second file
29(a forked session copies transcript lines, so the same fact arrives twice); and
30`requests_written + duplicates_seen` equals the qualifying assistant records, so the overcount we
31prevented is auditable rather than invisible. On a fresh ingest this makes the ledger identity
32exact: `requests_written` equals the rows in `requests`. The keyless tallies hold the same truth:
33`turn_events_written` and `content_segments_written` count rows the database actually stored — a
34forked file's copy of a fact another file already delivered is refused by the insert and never
35counted (the keyless-insert section below).

Creating tickets (lit)

Create tickets: `lit new --title "..." --topic <topic> --type task|bug|feature|chore|epic [--parent <parent-id>] [--bottom]`

<agent-instructions>`--description`: describe what to build and why; leave how to the implementer — write what survives a refactor of the code it concerns.</agent-instructions>
<agent-instructions>`--topic`: Required immutable issue topic slug (1-2 words; stable area of focus; e.g., 'refactor' or 'field-history')</agent-instructions>
<agent-instructions>New tickets are ranked to the TOP of the order by default (fresh work surfaces first). Pass `--bottom` to append at the bottom instead — use it when authoring a batch in order so creation order is preserved.</agent-instructions>

Create a follow-up parented to a just-closed ticket: `lit followup --on <closed-id> --title "..."` (ALWAYS capture work surfaced as a child ticket while context is fresh)

1"""Acceptance + theorem tests for the normalizer (ticket flex-cc-flex-j9m.3).
2
3The three stated acceptance criteria:
4 1. four records sharing one request_id yield exactly ONE RequestFact with the usage taken once;
5 2. a non-assistant record yields zero facts;
6 3. the same input always yields byte-identical facts (the determinism the pipeline rests on).
7
8Beyond those we assert the *meaning* the seam guarantees ([LAW:behavior-not-structure]): the
9tool-use summary is aggregated across every record of a request (no single record sees the whole
10turn); the cache-creation split is preserved per TTL; the project is the authoritative `cwd`, never
11the lossy directory slug; and each dropped duplicate is surfaced as data, never silently swallowed.

The file /Users/bmf/code/cc-flex/tests/test_store.py has been updated successfully. (file state is current in your context — no need to Read it back)

Now the API test — let me see how test_api.py builds its database and client:

Read/Users/bmf/code/cc-flex/tests/test_api.py
1"""Acceptance tests for the API boundary (ticket flex-cc-flex-j9m.8).
2
3The three stated acceptance criteria, plus the contract the seam promises:
4 1. each endpoint returns schema-valid JSON for a representative FilterState (Pydantic's
5 `response_model` is itself the validator — a malformed shape would 500 the response, so a 200 is
6 the proof);
7 2. an invalid FilterState (inverted or malformed date range) is rejected at the boundary with a 422
8 and a clear message, never a 500 or a silently-empty result;
9 3. `serve` requires a prebuilt database and never builds one implicitly — pointing it at a missing
10 or unbuilt database is a clean refusal — and its request handlers cannot write at all: the only
11 writer in the process is the explicitly-owned refresh loop (flex-live-ingest-vhv).
12
13Beyond those we pin the meaning the boundary carries forward ([LAW:behavior-not-structure]): unpriced
14volume is surfaced, not hidden, and a no-evidence slice is 'skipped', never a confident $0.00.

Finishing work (lit)

Mark a ticket done when all work is completed: `lit done <issue-id>` closes the ticket (success path; only from in_progress) and prints follow-up guidance for capturing what the next agent needs.
Close a ticket without marking done: `lit close <issue-id> --resolution <duplicate|superseded|obsolete|wontfix>` (resolution is REQUIRED — it records why the work was not finished; from any non-closed state). duplicate/superseded redirect to a canonical ticket; obsolete = the need is gone; wontfix = a standing decision not to do it. Reopening clears the resolution. Filter closed work by it: `lit ls --query "resolution:wontfix"`.
Create a follow-up ticket: `lit followup --on <closed-id> --title "..."` (ALWAYS capture work surfaced as a child ticket while context is fresh).

**Always** commit your work when you're done.

Ticket flex-limit-windows-1vr has been closed. Before moving on, do a quick review of related tickets. Is there any information that changes future work? Is there anything useful you know that can help the next agent? If so, update the relevant tickets to include this information. This will ensure future work does not drift or accidentally reverse intentional decisions we made while completing this work. This is critical for ensuring the outcomes are aligned with the user's expectations. Update the tickets NOW. You MUST NOT defer this requirement. You MAY ask the user if there is significant risk, but *strongly* prefer to silently make the updates and provide the user with a concise summary rather than pausing your work.

finalize-session

The last operation of a finishing turn: prepares instructions for a future agent. The launcher returns immediately. You MUST immediately stop and say nothing and use no tools after running this.

This is mandatory — you run it, you do not decide it

When you reach a finalization point — you closed a PR, finished the task you were handed, or crossed 300k–350k tokens of context — running finalize-session is the close-out. It is not a choice you weigh, a thing you ask the user about, or a step you defer "until later."

[LAW:dataflow-not-control-flow] running this is unconditional at a finalization point — the same path every time. The only variability is a value: the handoff message you pass.

The user being present is irrelevant. Presence is not a gate, a tiebreaker, or a reason to skip — you finalize on the work's state, never on whether a human is watching. "The user is here, so I'll skip it" and "I'll ask if they want me to" are both WRONG: this step requires no user action and asks for none.

The only gate, and the rationalizations that are never one

There is exactly one legitimate input: is the handed unit of work complete? Unit complete (PR merged, ticket closed, task delivered) or context at 300k–350k tokens → you run it, now, with no further deliberation. Unit not complete → you are not "deciding not to finalize," you are still doing the work: finish the unit, then finalize. There is no third state, and "skip finalize because X" is never one of them.

You can provide a 'hint' for the next stage, if valuable: /compact

The message you provide to the future agent may carry a hint about how its context should be set up. If you are in the middle of a task/epic and it would help the future agent to begin with a compacted summary of the work so far rather than a blank slate, you may specify '/compact' somewhere within the first sentence of your message. This gives the future agent a summarized version of that knowledge to start from. If you do not specify this, the future agent starts with ONLY the message you send it (and the standard system, user global, and project level guidance).

Include /compact in your message when the handoff needs the thread of what just happened — e.g., start the message with /compact or write "Use /compact and then continue the spec audit…".

Carry the goal forward — if one is set, it dies unless you carry it

If a /goal <condition> is active in this session, the handoff silently kills it. Every transport resets the session — tmux sends /clear or /compact, iTerm2 kills claude and relaunches a fresh process — and /clear and a new process each wipe the session-scoped goal. The next agent wakes with no goal, and the autonomous run you set up just stops — unattended, with nobody watching to notice it stopped. That silent halt is the exact failure this guards against.

So when a goal is in force, pass it: --goal '<the exact condition>' before your message. The launcher re-issues /goal <condition> into the reset session as a queued input after the handoff, so the next agent picks up the same condition and keeps grinding toward it.

  • The condition is a value you already hold — it is whatever was last set with /goal this session (you set it, or the user did). Reproduce it verbatim, including any bound clause like ... or stop after 20 turns.
  • No goal active → omit --goal. Nothing changes; this is not a field you invent, and an empty --goal is not a thing to pass.
  • Do not talk yourself out of it. The rationalization will be "the next agent will infer the goal from my message" — it will not. A goal is a harness condition re-checked after every turn, not a sentence in a prompt; if you do not re-issue it, it does not exist in the next session. Carrying it is the difference between an autonomous run that continues and one that quietly dies at the handoff.

Turn-ending discipline — the launcher invocation is the last act of the turn

Once you call the launcher, your turn is over. Stop. No closing text, no parting summary, no "scheduled!" confirmation, no further tool calls, no end-of-turn insights. The launcher's handoff scheduled → <target> (/<reset>) in Ns line is the only artifact this skill emits, and it is the last line your turn produces.

[LAW:dataflow-not-control-flow] the launcher's return is the data signal that the agent's turn has ended; the agent observes that signal and exits. There is no branch on "should I add a closing paragraph" — the same code path runs every time, and the data (launcher returned) picks the effect (turn ends).

Invocation

~/.claude/skills/message-in-a-bottle/bin/finalize-session [--goal '<condition>'] [message...]
  • --goal '<condition>' — optional, and only when a /goal is active this session. Re-establishes that goal in the reset session so the run continues. Leading argument; quote the condition. Omit entirely when no goal is set.
  • [message...] — a slash command, plain text, multi-line, or containing quotes/backticks/dollar signs. Quote it at invocation as usual (your shell does word-splitting and $VAR expansion before the script sees argv). Omit it to default to /next.

The launcher prints handoff scheduled → <target> … in Ns (log: <tempfile>) and exits. The log captures worker progress and any transport errors.

The transport is chosen by capability, most reliable first: tmux (reset the pane in place, verified by reading it back, then paste) → iTerm2 (kill the running claude and relaunch it fresh with the message as its initial prompt, delivered in the background with no focus steal) → file-drop (no live transport: the message is written to ~/.claude/finalize-pending-handoff.txt with delivery instructions, never silently dropped). You do not choose the transport; the launcher detects it. To preview the decision without scheduling anything, prefix FINALIZE_DRY_RUN=1.

Examples

Finalize and provide the future agent with guidance to pull the next ticket:

~/.claude/skills/message-in-a-bottle/bin/finalize-session /next

Hand off a specific instruction, providing a compacted summary of this session (include /compact in the message):

~/.claude/skills/message-in-a-bottle/bin/finalize-session \
  '/compact Continue the spec audit. Pick up at section 4 — the previous session left findings in spec/audit/section-3.md.'

Finalize while a goal is active — carry the goal forward so the autonomous run continues, and hand off /next:

~/.claude/skills/message-in-a-bottle/bin/finalize-session \
  --goal 'every open PR on this branch is merged or closed, or stop after 30 turns' \
  /next

share-slop

Uploads the current Claude Code session as a JSONL to paste.slopspot.ai as an unsubmitted draft, opens the editor for review, and prints the review URL. The remote claude-jsonl parser does the rendering — this skill is a thin uploader. The user reviews the conversation and clicks "Share it" to publish (review-before-publish).

When to use

  • "Share this session"
  • "Paste my conversation to slopspot"
  • "Give me a shareable link to this chat"
  • "/share-slop"

Don't use for sharing pre-existing files; this skill is specifically scoped to the current Claude Code session.

How it works

  1. $CLAUDE_CODE_SESSION_ID (exposed by CC) → session UUID.
  2. $PWD → project slug (each / and . replaced by -).
  3. Session file: ~/.claude/projects/<slug>/<session-id>.jsonl.
  4. Subagent transcripts (~/.claude/projects/<slug>/<session-id>/subagents/agent-*.jsonl) are concatenated onto the main blob, losslessly and verbatim. Each subagent line self-identifies (top-level agentId + isSidechain), so the server parser splits and reattaches them to their spawning Agent call by id-join — concatenation order is irrelevant. A session with no subagents uploads byte-identical to before. Each group's sibling agent-<id>.meta.json ({agentType, description}) is folded onto its first sidechain line so an orphan subagent (slash-command/skill run with no spawning Agent call, e.g. /recap) still renders with its real type; the fold is additive (never overwrites a source field) and keeps the line a valid sidechain line.
  5. POST the bundled content as { source: { kind: "claude-jsonl", content: <jsonl-text> } } to ${SLOPSPOT_URL}/api/draft (default https://paste.slopspot.ai).
  6. Server returns { draftId, url } where url is /?draft=<id>. Open ${SLOPSPOT_URL}<url> in the browser (best-effort) and print it. The user reviews the rendered conversation and clicks "Share it" to publish via /api/paste. The draft auto-expires in 1 hour if never published.

The slopspot side owns ALL parsing knowledge — this skill knows zero about the JSONL schema. If Anthropic changes the JSONL format, only the server parser needs to update.

Usage

Just invoke the helper script:

bash ${CLAUDE_PLUGIN_ROOT:-~/.claude/skills/share-slop}/share-slop.sh

Optional overrides:

  • SLOPSPOT_URL=http://localhost:4321 bash share-slop.sh — point at a local dev server.

Failure modes

The script fails loudly (no silent fallback) when:

  • CLAUDE_CODE_SESSION_ID unset → not running under Claude Code.
  • Session JSONL file missing → wrong project slug, or session was deleted.
  • Network error / non-200 from the API → the server's error message is propagated as-is.
  • File exceeds the server's MAX_BYTES (currently 8 MB) → server returns 413 with size info.

Privacy note

The uploaded JSONL contains the entire current session — every prompt, every assistant reply, every tool call and its output, including every subagent's full transcript. Thinking blocks and CC system reminders are filtered server-side, but anything you typed or any file content the agent (or a subagent) read remains. Pastes auto-delete after 30 days; there is no edit or delete affordance before then. Don't run this in a session that touched secrets or sensitive paths.
