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 | $0.00281 | $0.00281 |
| Opus 5.5 | $0.00112 | $0.00112 |
| Sonnet 5.5 | $0.00056 | $0.00056 |
| Haiku 4.5 | $0.00028 | $0.00028 |
Grade A, and why
skills 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 2mo 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
ag-skills
Agent skills for AG Grid / AG Charts / AG Studio, published to users via npx skills add ag-grid/skills. Skills live in skills/; each has a VERSION.md (semver) that the skill checks at runtime against the copy on main to warn about being out of date — bump it when changing a skill's behaviour.
Regenerating documentation indexes
skills/ag-dev/references/<product>/documentation-index.md is half-generated. The preamble (down to the first ---) is hand-authored and preserved; everything below is regenerated from each product's docs nav.
node scripts/ag-dev/generate-documentation-index.mjs [grid|charts|studio|all]
Requires an authenticated gh (it reads nav.json from each product's latest tagged release, including the private ag-studio repo). Re-run after a product release to refresh the page list. The reduction rules and per-product drop/trim tuning live in the script; edit those constants there.
Tests
Skill-behaviour tests run through the harness in tests/harness/ are intended to be run by developers as part of the development process. They take a very long time to run, so typically one would select a single test case to run at a time. Do not run these automatically after making changes.
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.
