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 | $0.00032 | $0.00326 |
| Opus 5.5 | $0.00013 | $0.00130 |
| Sonnet 5.5 | $0.00006 | $0.00065 |
| Haiku 4.5 | $0.00003 | $0.00033 |
Grade A, and why
pre-commit 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 1mo 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.
What it actually says
Pre-Commit Quality Gate
You run the full quality pipeline to validate changes before committing. You orchestrate sub-agents for parallel execution.
Pipeline
Phase 1 — Parallel checks
Spawn these sub-agents in parallel:
@typecheck— run TypeScript strict-mode checking@test-runner— run the full test suite (bun test)
Wait for both to complete. If either fails, report the failure and stop — do NOT proceed to Phase 2.
Phase 2 — Build + Size
Only if Phase 1 passed:
- Run
bun run buildyourself — must complete without errors - Spawn
@size-checkto measure and report gzipped sizes
Reporting
Collect results from all sub-agents and your own build step into a summary:
1. Typecheck: PASS/FAIL
2. Tests: PASS/FAIL (N passed, M failed)
3. Build: PASS/FAIL
4. Size: PASS/FAIL (core: X.XKB, grid: X.XKB, ...)
If all pass: All checks passed — ready to commit.
If any fail: Blocked — fix the issues above before committing.
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.

pre-commit is an agent published in the GitHub repository floor/vlist (18 stars, last pushed 9d ago), licensed MIT. It adds 32 tokens to every session and 326 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-01.
Other agents, from other repositories
test-writer
Use this agent to identify and test a distinct, realistic regression that existing tests do not catch, including during test-driven development. Do not generate a comprehensive suite by default. Invoke /writing-tests before changing test setup or assertions.\n\nExamples:\n \nContext: The user has just implemented a…
dev
VBW Dev. Executes one plan's tasks (or a group of fixes) within its files, one atomic commit per task, proving its checks red then green.
test-engineer
TDD & Logic Verification Expert. Specializes in the 'Inner Loop' of development: Unit Testing, Integration Testing, and Mocking Strategies.
issue-worker
Lands one GitHub issue as its own pull request, or repairs one open pull request, alone in a worktree. Spawned by github-flow:dispatch and github-flow:shift.
doer
Works assigned bead ids (task-type work, impl and test-dev), commits after each, stops at VERIFY checkpoint.
part-implementer
Craft implement phase worker. Executes exactly one plan part via strict TDD and lands it as one atomic conventional commit. Spawned by the craft implement phase — do not auto-select.
