repo-context-ledger: Instructions file for Claude Code

CLAUDE.md

repo-context-ledger CLAUDE.md is an instructions file for Claude Code from gviiisen/repo-context-ledger. It costs 372 tokens per session, scanned A, original, MIT.

Instructions for Claude Code and a repository context ledger that stores project knowledge and supports handoffs between coding sessions.

In plain words
What is it for?
Use them to query required project context, continue a named earlier task, preserve the correct session epoch, and avoid reading or changing another user's private session.
Why use it?
They limit unnecessary reading and help an agent safely resume earlier work with the right context and session ownership.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions Claude Code; mentions AGENTS.md.

This is gviiisen/repo-context-ledger's own configuration. It tells Claude Code how to work on repo-context-ledger itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything repo-context-ledger configures →

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

repo-context-ledger CLAUDE.md scanned grade A with 0 findings 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 2d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Claude Code instructions

@AGENTS.md

Use already loaded task context first. For a missing or changed background question, run context --query "<task>" before broad documentation exploration; do not repeat routing for a routine follow-up whose context is sufficient. Read only the Context Bundle's Required reads initially. Never recursively read docs/ai, docs/specs, or docs/changes. Do not open completed Change bodies unless the plan selects one, a required Pack cites one for a named reason, or the user asks for historical reasoning. Required reads are a starting route, not a maximum code-reading limit. Expand context only after stating the unresolved question, and always expand whenever callers, implementations, configuration, persistence, permissions, concurrency, retries, tests, or external boundaries can affect the behavior. A same-window 'continue' on a known active task keeps its session and epoch without another resume. For a real window/tool handover, paused task, or missing task identity, resolve only the missing state and use an owned unique Resume Capsule. Continue the same Ledger session with resume --query "<keywords>" --tool claude; keep the returned continuation epoch and pass --epoch <n> to later writes. Never read, resume, pause, checkpoint, finish, or invalidate another principal's private session unless an explicit unexpired grant authorizes that exact access. Read-only grants never permit writes. A foreign overlap without a grant permits only Git-tracked Pack/spec/Change guidance.

Treat Git-tracked Context Packs, stable specs, and handoffs as the cross-Agent source of truth. Follow the repository context ledger workflow without asking the user to run lifecycle commands. Never message or steer another user-owned task unless the user explicitly requested cross-task coordination.

Changes

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.
