self-review

self-review is a skill for Claude Code, Codex from HugoRCD/evlog. It costs 117 tokens per session (2,392 once invoked), scanned A, original, MIT.

A weekly review skill for the evlog repository and its own agent setup. It checks both for drift—when code, documentation, and declared capabilities disagree—and for useful missing capabilities.

In plain words
What is it for?
Use it for recurring maintenance reviews that report evidence-backed inconsistencies and proposals for worthwhile improvements.
Why use it?
It helps find problems that ordinary tests may miss, such as unused features, outdated guides, or repeated manual work.

About the project

evlog is a TypeScript-first logging and observability project built around wide events and structured errors across runtimes. It is intended to help developers record application behavior and diagnose failures.

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

self-review 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 5d 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 — 139 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Self review

Two halves, run together, because they fail in opposite directions.

Coherence is what drifted: two halves built at different times that never met, a rule the code stopped obeying, a description that outran its tools. Nothing is broken, no test fails, nobody files it.

Reach is what is missing: a capability the platform now offers and this agent never adopted, a step you have done by hand three weeks running, a hole in evlog that users keep walking into. Nothing is wrong, so nothing prompts it.

Skipping the second half turns this run into a regression sweep. Skipping the first turns it into a wishlist. Run both.

Two kinds of output, two bars

A finding contradicts something written down or something declared: a rule in a guide, a capability the app announces, a description that promises behavior the tools do not deliver. Name the prose or the declaration it contradicts, or drop it.

A proposal is a capability worth having that nothing yet argues for. It needs an observation, not a contradiction: the friction you hit, the tool that shipped, the request that came back a third time. Name what you observed and when, or drop it.

Neither bar is met by taste. "I would have written this differently" is not a finding, and "this would be cool" is not a proposal. Both are refusals to do the work of grounding.


Part one: coherence

A. Wiring gaps

Something is produced and nothing consumes it. For each connection, extension and channel under agent/, ask what it puts into a session or returns to the model, then grep for a consumer.

  • Context blocks eve injects, session state, channel metadata. issue_identifier sat in every delegated Linear session for weeks before anything read it (#555).
  • Values computed in agent/lib/ and returned to no one.
  • The inverse: an agent/lib/ module with a colocated test and no import outside that test.

B. Guides the code stopped obeying

Guide Check
Root AGENTS.md A new entrypoint registered in all three of package.json#exports, package.json#typesVersions, tsdown.config.ts. No evlog/shared import (evlog/toolkit is the public name). No HTML comment in a Vue <template>.
Root AGENTS.md Every framework integration exposes the same contract: evlog(), useLogger(), log.fork(). evlog/workers is the documented exception.
apps/evi/docs/capability-placement.md The two-layer rule: a file under agent/ outside agent/lib/ holding logic instead of wiring, an agent/lib/ module with no colocated *.test.ts, or a caller check written inline instead of going through agent/lib/trust.ts.
packages/evlog/test/README.md A framework test driving the app by hand instead of through its real request driver.
Root AGENTS.md A behavior change whose matching .agents/skills/ or skills/ SKILL.md still describes the old shape.

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.

self-review is a skill published in the GitHub repository HugoRCD/evlog (1,831 stars, last pushed 3d ago), licensed MIT. It adds 117 tokens to every session and 2,392 once invoked, about $0.0006 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 2026-08-30.
