ariadne: Skill for Claude Code

.claude/skills/reconcile-registry/SKILL.md

reconcile-registry is a skill for Claude Code from CRJFisher/ariadne. It costs 82 tokens per session (4,754 once invoked), scanned A, original, MIT.

A registry-maintenance tool that compares known issue rules with completed code changes and reported classifier drift. A registry is a stored list of rules; drift means a rule no longer matches current behaviour.

In plain words
What is it for?
Use it to detect fixes that landed, flag rules needing correction, dispatch rule-fixing agents, and mark selected rules as permanent.
Why use it?
It reduces stale issue rules and keeps changes to the registry under deliberate human control.

Written for Claude Code: allowed-tools in frontmatter. Also seen: reads .claude/ paths; names the AskUserQuestion tool.

This is CRJFisher/ariadne's own configuration. It tells Claude Code how to work on ariadne 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 ariadne 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

reconcile-registry 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 17d 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 — 295 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Reconcile Registry

Reconcile the known-issues registry at .claude/skills/triage/known_issues/registry.json against work the rest of the pipeline has already done: fixes that landed in this repo's git log, drift that triage published, and rules the human elects to make permanent. This skill is the deliberate, human-invoked step that detects those mechanical writes and proposes them — the registry's analogue of prioritize.

It owns no logic of its own beyond one orchestration duty — dispatching a classifier-fixer agent per drift-flagged rule after a --drift apply (step 4). All registry work runs through one script:

.claude/skills/triage/scripts/reconcile_registry.ts

That script is the only human-invoked writer of registry.json in the pipeline, and it reaches the registry only through atomic_update_registry(path, mutator) — one lock-fenced read-mutate-write per invocation. It never runs on the autonomous sweep: the human is the registry's sole decider, and this skill exists to make each decision cheap, never to make it autonomously.

What it detects

The script scans the mechanically-detectable signals and proposes the corresponding registry write. It never authors rule prose and never makes the permanent judgment — those stay human creative and judgment work. Beyond the detected signals, it also accepts directed name-mode flips (--id ... --fixed --reason, --id ... --promote) where the human names the rules and the transition rather than letting detection propose it.

# Signal (mechanically detected) Proposed registry write
1 a fix-bearing git log scope in this repo matches a wip rule's backlog_task wip → fixed
2 a published triage_results[].classifier_regressions[] names a rule — its rule_id field carries the registry rule's group_id set drift_detected: true; append new drift_evidence[] rows
3 the human elects to promote a rule (--id <group_id> --promote) flip to permanent; regenerate permanent_data.ts
4 the human retires a rule by name (--id <group_id>... --fixed --reason) delete the row(s); unlink their check_*.ts

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.
