ThumbGate: Skill for Claude Code

.claude/skills/task-state-ledger/SKILL.md

task-state-ledger is a skill for Claude Code from IgorGanapolsky/ThumbGate. It costs 97 tokens per session (974 once invoked), scanned A, original, MIT.

A task-tracking note for coding work that takes several steps, spans multiple conversations, or affects production. It keeps the current goal, progress, and next actions in one place.

In plain words
What is it for?
It helps track multi-step tasks, work across multiple pull requests, and production changes.
Why use it?
It prevents the agent from repeatedly reconstructing the state of a task from Git, GitHub, or deployment data.

    Skill attempts to fill the context window with filler content, displacing legitimate instructions and safety constraints. This can degrade agent performance or bypass safety boundaries.
    Fix: Implement context-window management that detects and rejects padding or stuffing attempts. Prioritize system instructions over user-injected content.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

task-state-ledger scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Task State Ledger — Stop Getting Lost

The failure this prevents

You re-derive state every turn (where's the PR, what's on main, what's deployed) with expensive gh/git/curl dumps. The dumps flood context, bury the signal, and you lose the thread. This is the "constantly stuck and lost" failure. The fix is mechanical: write state down once, update it as you go, read it instead of re-deriving it. (Anthropic context-engineering: external structured note-taking is one of the three core long-horizon techniques, alongside compaction and sub-agents — see https://www.anthropic.com/engineering/effective-context-engineering-for-ai-agents)

The rule

For any task with 3+ steps or that crosses a turn, the FIRST action is to create or open a ledger at .thumbgate/implementation-notes.md or a task-specific gitignored .thumbgate/implementation-notes/<date>-<task>.md. Do not write operator scratchpads under tracked .claude/implementation-notes/; those are private working notes, not product documentation. The ledger is the single source of truth.

Ledger format (keep it short — it's a dashboard, not a diary)

# <task> — <date>

## Goal (one sentence)
<the actual end state that means "done">

## Current step
<the ONE thing in flight right now>

## State (verified facts only — each with how/when verified)
- main HEAD: <sha> (git rev-parse origin/main @ HH:MM)
- deployed buildSha: <sha> (curl /health @ HH:MM)
- PR #NNNN: <state>/<mergeState> (gh pr view @ HH:MM)

## Steps (sequential — one in_progress at a time)
- [x] step that's done — evidence
- [ ] step in flight  ← YOU ARE HERE
- [ ] next step
- [ ] ...

## Decisions & corrections
- <decision> because <why>  (mark VERIFIED / UNVERIFIED)
- WRONG: <thing I claimed that was false> → corrected to <truth> @ HH:MM

## Blockers / open questions for the CEO
- <thing only the user can unblock>

Protocol

  1. Open the ledger before doing anything else on a multi-step task. If it exists, read it instead of re-deriving state.
  2. Update "Current step" + "State" after each verification, not at the end. When you run the verifying command, write its result + timestamp into the ledger.
  3. One step in_progress at a time. If you're tempted to start a second, stop — see the scope-discipline skill.
  4. Log corrections inline. When "are you sure?" reveals you were wrong, write the WRONG→corrected line. This stops you re-making the same wrong claim.
  5. Read the ledger at the start of every turn on a continuing task. That is how you stop being "lost": the answer to "where am I" is a file read, not 10 tool calls.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

task-state-ledger is a skill published in the GitHub repository IgorGanapolsky/ThumbGate (26 stars, last pushed today), licensed MIT. It adds 97 tokens to every session and 974 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
