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 | $0.00317 | $0.00317 |
| Opus 5.5 | $0.00127 | $0.00127 |
| Sonnet 5.5 | $0.00063 | $0.00063 |
| Haiku 4.5 | $0.00032 | $0.00032 |
Grade A, and why
mssql-performance-skills AGENTS.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 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
AGENTS.md — mssql-performance-skills
What this is
A library of Markdown skills for SQL Server performance tuning. No build system, no tests, no dependencies.
All skill details, check counts, prefix map, contributor workflows, and conventions — see CLAUDE.md.
Verify before commit
bash scripts/verify-docs.sh
Runs documentation consistency checks. Fails block commit; warnings are advisory.
A .claude/settings.json PostToolUse hook auto-runs this after every Write/Edit — check output after file edits.
Critical gotchas
Dollar signs in SKILL.md break at runtime. The Claude skill loader does shell variable expansion on SKILL.md content. Never write $0.012 or $[expr] — use USD 0.012. verify-docs.sh catches this.
references/check-explanations.md is NOT loaded at runtime by default. Only SKILL.md is read automatically by the skill loader. All thresholds and triggers must live in SKILL.md. The reference file is on-demand context — Claude may load it when a user asks "explain check X" or for deeper fix-option detail.
Dispatcher-style skills are exempt from check-count matching. Skills with no own checks have references/check-explanations.md files that describe methodology, not per-check entries.

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.
