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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00021 | $0.00299 |
| Opus 5 | $0.00010 | $0.00150 |
| Sonnet 5 | $0.00004 | $0.00060 |
| Haiku 4.5 | $0.00002 | $0.00030 |
Grade A, and why
code-change-verification 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 8d 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
Code Change Verification
Purpose
Provide a repeatable final gate for source changes before merge or release.
When to use
Use for every source-code modification and before completing a substantial pull request.
Inputs
- the working-tree diff and base revision;
- project test and eval commands;
- dependency, generated-artifact, and runtime context.
Required checks
- Inspect the full diff and changed file list.
- Run project tests.
- Run deterministic evals.
- Check changed behavior against the requested contract.
- Check for unexpected files.
- Check dependency changes.
- Check generated artifacts and secrets.
- Summarize remaining risk and unverified behavior.
Output contract
Return exactly one top-level status:
PASS
PASS WITH WARNINGS
FAIL
Include commands, exact results, changed scope, warnings, and remaining risk below the status.
Failure conditions
FAILif a required test/eval fails, the diff contains an unrelated change, or a secret is detected.PASS WITH WARNINGSwhen deterministic checks pass but required runtime or external-platform evidence is unavailable.- Never claim a test ran when it did not run.
Verification
Run the final commands from the repository contract, review git diff --check, inspect status, and repeat any invalidated gate after the last change.
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.

code-change-verification is a skill published in the GitHub repository harukiseller-droid/commerce-agent-bench (102 stars, last pushed 26d ago), licensed MIT. It adds 21 tokens to every session and 299 once invoked, about $0.0001 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.

adversarial-reviewer
Adversarial code review that assumes bugs exist and hunts for them. Use when asked to review code, find bugs, audit for correctness, stress-test a PR, or when someone says "tear this apart" or "what's wrong with this". Give no benefit of the doubt — every line is guilty until proven innocent.

Trigger: Go tests, go test coverage, Bubbletea teatest, golden files. Apply focused Go testing patterns.
semgrep-rule-variant-creator
Creates language variants of existing Semgrep rules. Use when porting a Semgrep rule to specified target languages. Takes an existing rule and target languages as input, produces independent rule+test directories for each language.
brooks-sweep
Full-sweep mode: runs a unified analysis across all quality dimensions — code decay, architecture, tech debt, and test quality — then applies fixes directly to the codebase. Safe changes are auto-applied; risky changes are confirmed before execution. Drawing on twelve classic engineering books. Triggers when: user…
