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 | $0.01056 | $0.01056 |
| Opus 5.5 | $0.00422 | $0.00422 |
| Sonnet 5.5 | $0.00211 | $0.00211 |
| Haiku 4.5 | $0.00106 | $0.00106 |
Grade A, and why
mini-spec CLAUDE.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 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 — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Project Guidelines
Releases
Version is tracked in .claude/skills/mini-spec/README.md. Increment the patch number unless the user says otherwise.
Release contents (zip file):
.claude/skills/mini-spec/(skill files).claude/skills/minimap/(skill files) — required, not optional:SKILL.md's first instruction is to invoke/minimap, so a zip without it ships a skill whose opening directive points at nothing. v2.9.0 ships exactly that broken pair: minimap was split out in520a783(2026-06-07), the tag landed 2026-06-09, and the zip's SKILL.md names/minimapthree times with no minimap alongside it..claude/agents/{spec-agent,alarm-puller,measurer,coder}.md(agents) — all four:SKILL.mdtells agents to spawnalarm-pullerandmeasurer, so leaving them out ships the same dangling directive as the minimap case below. Name them rather than zipping the directory:code-simplifier.mdthere is untracked and comes from the plugin. Through v2.11.0 the list named onlyspec-agent; v3.0.0 is the first zip with all four.- Exclude Emacs backup files:
zip -x "*.~undo-tree~" - Exclude
.claude/skills/mini-spec/notes.md: it is git-ignored private notes, andzip -rtakes the whole directory, tracked or not. The v4.0.1 build picked it up until the file list was compared with v4.0.0's zip. Compare the new zip's file list with the previous release's before uploading:diff <(unzip -Z1 new.zip | sort) <(unzip -Z1 old.zip | sort).
Release process:
- Check existing tags (
git tag -l) to confirm next version number - Update version in
.claude/skills/mini-spec/README.md - Commit the skill README (ask user about other new or changed files)
- Tag it (e.g.,
v0.9.3) - Push commit + tag
- Create GitHub release with
gh release create - Upload zip to the release
- Build and upload binaries:
cd tool && make releasethengh release upload <tag> bin/minispec-*(releasealso rebuilds the host'sbin/minispec, which is not a release asset) - Include in release notes:
claude plugin install code-simplifier
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.
