no-mistakes is a local Git proxy that validates changes in an isolated worktree before forwarding a push to the real remote and opening a pull request. It is for developers and coding agents that want automated checks, safe fixes, CI repair, and human review before changes are published.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.08228 | $0.08228 |
| Opus 5.5 | $0.03291 | $0.03291 |
| Sonnet 5.5 | $0.01646 | $0.01646 |
| Haiku 4.5 | $0.00823 | $0.00823 |
Grade A, and why
no-mistakes AGENTS.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 3d 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 — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
This file is for agentic coding tools working in this repo.
This repository is a Go CLI app named no-mistakes.
The binary entrypoint is cmd/no-mistakes; implementation code lives under internal/, and the package names there are the layout map (CLI in internal/cli, daemon in internal/daemon, pipeline and steps in internal/pipeline, agent adapters in internal/agent, terminal UI in internal/tui, shared infrastructure in internal/git, internal/ipc, internal/config, internal/db, internal/paths, internal/types).
Build, test, and release commands are owned by the Makefile; read it for the full target list instead of relying on a copy here.
Safest local verification sequence after non-trivial changes:
gofmt -w .make lint(generated-skill drift check plusgo vet)go test -race ./...(the e2e suite is behind thee2ebuild tag and excluded)make e2ewhen touching agent integrations, the e2e harness, or recorded fixturesgo build -o ./bin/no-mistakes ./cmd/no-mistakes
Where detail lives
- User-facing semantics: the docs site under
docs/src/content/docs/(reference/repo-config.mdandreference/global-config.mdown config keys,reference/pipeline-steps.mdowns step behavior,reference/environment.mdowns env vars and telemetry,concepts/gate-model.mdandconcepts/daemon.mdown those models). - Per-area implementation maps (owning functions, invariants, regression lists):
.agents/skills/<area>/SKILL.md(.claude/skillsis a symlink to it). Read the matching skill before changing that area. - Provider CLI traps (glab flag drift, tea JSON shapes, Origin's draft-by-default create, GitHub user-attachments, opencode failure wire shape and retry gating) are owned by the comments in
internal/scm/gitlab/gitlab.go,internal/scm/gitea/gitea.go,internal/scm/origin/origin.go,internal/scm/github/attachments.go, andinternal/agent/opencode*.go; extend them there when you hit new drift. skills/no-mistakes/SKILL.mdis generated frominternal/skill/skill.go; never hand-edit it,CHANGELOG.md, or other generated files.
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.
