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 | $0.00013 | $0.00125 |
| Opus 5.5 | $0.00005 | $0.00050 |
| Sonnet 5.5 | $0.00003 | $0.00025 |
| Haiku 4.5 | $0.00001 | $0.00013 |
Grade A, and why
validation-gate 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.
The source is not reproduced here
A licence we could not identify
The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.
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.

validation-gate is a command published in the GitHub repository iLearn-Lab/EvoHarness (58 stars, last pushed 3mo ago), with no licence file. It adds 13 tokens to every session and 125 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 2026-08-30.
Other commands, from other repositories
tdd
Methodology: tdd-strict Purpose: Manage Red→Green→Refactor cycles. Gate enforces test-first order in git history.
bdd
A command for writing and tracking BDD scenarios using Given, When, and Then steps. BDD, or behaviour-driven development, describes expected user behaviour in examples that can be checked during implementation.
sql_schema
Command "sql_schema" from agentis-tools/ctx, covering ctx sql — public schema (v1), stability contract, views, v1.symbols — one row per symbol and v1.edges — one row per relationship.
verify
Run a repository verification loop with runner-first execution, deterministic stages, and explicit PASS/FAIL/SKIP output. Use for fast or full validation of a consumer repository. Not for: mutation, fixing failures, dependency remediation, or merge approval. Output: runner summary or a complete fallback stage table.
precommit
Run the deterministic pre-commit pipeline in fast or full mode through the packaged runner. Use when handing off repository changes. Not for: ad hoc replacement checks, dependency audits, or read-only verification. Output: runner-owned changed-file reporting and final verdict.
best-practices-check
Evaluate workspace against Claude Code best practices.
