alego: Skill for Claude Code

.agents/skills/cordis-styling-nitpicking/SKILL.md

cordis-styling-nitpicking is a skill for Claude Code, Codex from singula-ai/alego. It costs 68 tokens per session (1,632 once invoked), scanned A, a copy of cordis-styling-nitpicking, MIT.

A focused code-review guide for Cordis plugins, tracing how they create, use, and release shared resources. Cordis is a framework whose plugins register services and cleanup actions.

In plain words
What is it for?
Use it to audit plugin entry points, service ownership, event listeners, side effects, disposal, and teardown behavior.
Why use it?
Lifecycle mistakes can leave effects active, release resources too early, or keep incorrect shared state. The guide limits findings to defects supported by the code and its tests.

This is singula-ai/alego's own configuration. It tells Claude Code and Codex how to work on alego 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 alego 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

cordis-styling-nitpicking 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 6d 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.

Origin

This is a copy

89% identical to cordis-styling-nitpicking — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Cordis Ownership and Lifecycle Audit

This is a focused semantic review of Cordis ownership and lifecycle. Start a repository audit from exported plugin entrypoints (apply or a concrete default export invoked by Cordis), then trace module initialization, registered services, listeners, effects, disposers, and transitive calls reachable from those roots. Exclude unrelated helpers, build tools, CLI paths, and tests as finding targets. Read tests and vendored Cordis to establish behavior; report a generated defect against its owning source. Do not report defects in vendored code under this skill.

Sources of truth

Review workflow

  1. Locate mutable owners, registrations, resource acquisition, and work admission reachable from the requested plugin roots. For large scopes, use independent directory scans, then consolidate findings involving the same consumer and resource.
  2. Trace ownership through the actual context: in a traceable service method, this.ctx is the caller's context. Identify who owns each effect and the disposer that releases it.
  3. Trace cleanup through every await to its last service call, emitted event, acknowledged operation, and durable write. Include indirect event delivery and cleanup performed after abort, kill, or cancellation.
  4. Compare consumer completion with the time each required listener, registry, writer, connection, domain, or transport becomes unusable. Inspect the current Cordis implementation; reverse start order and dependency registration alone do not establish completion order.
  5. Establish a legal failing interleaving and observable impact. Check existing cancellation, explicit sequencing, and documented discard semantics before reporting. Use controlled promises for reproduction where feasible, and label source-only findings accurately.

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.
