Token cost

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.

Security

Grade A, and why

websearch 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 6d 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

Use the live Exa tool schemas, not remembered parameter names. Quick lookup: one focused search, then answer with citations. Documentation: find the official page and crawl the relevant section only. Code/debug: use code context, then broaden only when the first results do not answer the issue. News: preserve publication dates. Compare: search the actual alternatives. Research/similar: use supported search parameters; never invent an enum value.

Honor --domain/--exclude, --after/--before, -n, --fresh and requested output format when the tool supports them; explain unsupported filters. Prefer short relevant excerpts, not full pages. Crawl a full passage when needed to verify a key claim. Do not paste raw response metadata twice.

--deep permits targeted follow-ups for named remaining gaps, up to three passes including the initial search. Stop sooner when answered, saturated or no new useful evidence appears. No fixed quota of queries or sources. Run independent tool calls together without launching agents for simple lookups.

Cite each source that supports a claim; distinguish observed facts, inference and uncertainty. Keep dates honest. Write a report only with --save or an explicit request. --json returns structured results. --info uses the existing references/info-text.md.

Execution policy

Work solo. Ask before any subagent or reviewer, even in auto mode. Explain the independent scope and expected benefit first. No hidden advisor, nested delegation, model retuning, repeated successful checks, or progress spam. Use existing context before asking questions. Stop when the requested result is delivered. User stops and scope changes override pending steps.

Files

What ships with it

7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
