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 | $0.02503 | $0.02503 |
| Opus 5 | $0.01252 | $0.01252 |
| Sonnet 5 | $0.00501 | $0.00501 |
| Haiku 4.5 | $0.00250 | $0.00250 |
Grade A, and why
autospec 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 9d 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 — 247 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Guidance for Claude Code when working with this repository.
Autospec Claude Skills
autospec init --ai claude installs Claude project skills in .claude/skills/autospec.*/SKILL.md. They preserve existing slash-style invocation such as /autospec.plan and set disable-model-invocation: true so agents do not invoke them automatically.
Prerequisites
- Go 1.25+: Check with
go version - Claude CLI: Authenticated (
claude --version) - Make, golangci-lint: For build/lint (
make lint)
Commands
# Build & Dev
make build # Build for current platform
make test # Run all tests (quiet, shows failures only)
make test-v # Run all tests (verbose, for debugging)
make fmt # Format Go code (run before committing)
make lint # Run all linters
# Single test
go test -run TestName ./internal/package/
# CLI usage (run `autospec --help` for full reference)
autospec run -a "feature description" # All stages: specify → plan → tasks → implement
autospec prep "feature description" # Planning only: specify → plan → tasks
autospec implement --phases # Each phase in separate session
autospec implement --tasks # Each task in separate session
autospec st # Show status and task progress
autospec doctor # Check dependencies
Post-Change Polish (REQUIRED)
After significant code changes, automatically invoke the repo-local polish skill before final handoff. Use it to update changelog/docs and run the required validation targets. Do not wait for an explicit /polish request unless the change is trivial or docs-only.

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.

autospec CLAUDE.md is an instructions file published in the GitHub repository ariel-frischer/autospec (141 stars, last pushed 1mo ago), licensed MIT. It adds 2,503 tokens to every session, about $0.0125 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.
