stellar-raven: Skill for Claude Code

.agents/skills/truth-maintenance/SKILL.md

truth-maintenance is a skill for Claude Code, Codex from stellar-experimental/stellar-raven. It costs 88 tokens per session (2,006 once invoked), scanned A, original, Apache-2.0.

A coordinator for keeping a coding-agent project accurate as its live services, tests, reference answers, and issue records change. It brings several maintenance workflows together and records the outcome in a round ledger.

In plain words
What is it for?
Use it to coordinate live-drift checks, evaluation runs, trusted-answer updates, and follow-up work on improvements, issues, and pull requests.
Why use it?
It helps prevent documentation, test expectations, service behaviour, and tracked fixes from quietly drifting apart.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents); mentions AGENTS.md.

This is stellar-experimental/stellar-raven's own configuration. It tells Claude Code and Codex how to work on stellar-raven 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 stellar-raven 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

truth-maintenance 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 7d 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.

How it starts

The opening of the file, as written. The whole thing — 154 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Truth maintenance

This is the coordinator skill. It does not replace the lane runbooks:

  • live-drift-resolution owns catalog/inventory/spec/op-class drift from live upstream services.
  • run-evals owns eval instrument selection, result review, and eval-round closeout.
  • golden-truth owns any golden question/answer/key-fact/avoid/source/grader-note change.
  • improvements-pipeline owns improvements/, intake, probes, upstream issue/PR tracking, and index/lint.

Use this skill when the work crosses lanes or when the user asks for "truth is up to date" rather than a single drift issue. The product is a maintenance round recorded in a ledger, with lane verdicts, evidence, follow-ups, and cleaned-up spawned work.

Orchestration contract

Use the global herdr skill for spawning, monitoring, and cleanup: one pane per lane, split from your own pane. Select model and effort explicitly per AGENTS.md. This skill adds only truth-maintenance lane structure.

Open one ledger for the round at .agents/rounds/<YYYY-MM-DD>-truth-maintenance.md. Use fixed headings so spawned agents can append without clobbering each other:

# Truth maintenance <YYYY-MM-DD>
## Scope
## Lane plan
## Drift verdict
## Eval verdict
## Golden verdict
## Improvements/issues/PR verdict
## Own-repo todos
## Decisions
## Final checklist

By default, workers research/review and append to ledger; coordinator owns repo edits. Delegate patches only when write set is narrow, explicit, and disjoint.

Reviewer and author are separate roles. A spawned reviewer must re-derive from files, diffs, live probes, or GitHub state, not rubber-stamp the coordinator's summary. Let reviewers finish unless the user cancels or they clearly error.

Stale-gospel queue (the freshness lane — owned by this skill)

Golden freshness is not maintained by batch re-audits; it is a standing due-date queue. Every scheduled-freshness QA case carries a truth.reverifyBy date, and npm run eval:qa:lint -- --stale fails on any past-due case — wired into PR CI and the daily refresh workflow, so a date passing fires within 24 hours. This skill owns that queue:

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.

truth-maintenance is a skill published in the GitHub repository stellar-experimental/stellar-raven (6 stars, last pushed 3d ago), licensed Apache-2.0. It adds 88 tokens to every session and 2,006 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
