Project instructions for working on the `river-review` codebase, including its repository rules, decision process, change limits, and reporting requirements. They also define when approval is needed before editing or making risky changes.

In plain words
What is it for?
Use them when exploring or modifying the project, especially before changing protected files, adding dependencies, altering project instructions, or making broad design changes.
Why use it?
They reduce accidental architectural, destructive, or out-of-scope changes and make completed work easier to review.

Written for Claude Code: PreToolUse hook event. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions subagents.

This is s977043/river-review's own configuration. It tells Claude Code how to work on river-review 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 river-review 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

river-review 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 yesterday.

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.

Claude Code Project Guide (river-review)

Repo rules: Follow all sections in AGENTS.md. This file adds only Claude Code-specific work policy.

Decision Policy

  • Proceed autonomously: read-only exploration, running commands listed in .claude/settings.json allow list, editing paths in AGENTS.md "Editable" scope.
  • Ask before acting: editing paths in AGENTS.md "Ask before editing" scope, adding dependencies, running commands not in allow list.
  • Always ask: architectural changes, modifying AGENTS.md or CLAUDE.md, any destructive git operation, changes touching src/ that may break skill or schema alignment.

Change Policy

  • One logical change per branch. Do not bundle unrelated fixes.
  • Minimal diff — do not refactor, reformat, or annotate code outside the task scope.
  • Do not add features, patterns, or dependencies not explicitly requested.
  • If a task seems too large for one session, propose a plan and get approval first.

Reporting

After completing a task, state concisely:

  1. What changed (files and purpose).
  2. What was verified (commands run and results).
  3. What needs human review (assumptions, edge cases, "ask before" paths touched).

If a check fails, show the failure output and proposed fix before applying.

AI Misoperation Guards

The ledger docs/development/guard-ledger.yaml is the SSoT for this list under its guards: key — it records each guard's mechanization level, verifiedBy paths, and reviewAfter date, and the required check Meta consistency fails when the two drift. Add, rename, or remove a guard in the ledger and here in the same PR; retire per docs/development/improvement-flow.md Step 9. The same file also tracks timed decisions that are not guards under decisions: (deprecated assets, workflows under observation, temporary exclusions) — those have no bullet here, and Meta consistency checks only that each target: path still exists (#1843).

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.
