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

Self-Install-Tools-And-MCP-When-Necessary 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 9d 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

If needed to complete the task, you may install required tools, dependencies, local utilities, skills, or MCP servers yourself.

Only do this when the installation is clearly necessary for progress, validation, automation, debugging, or repository workflow support.

Prefer:

  • existing project tools first
  • minimal, well-scoped additions
  • commonly used, maintainable solutions
  • setup that matches the current project and workflow

Do not install unnecessary, redundant, risky, or unrelated tools.

When installing something new:

  • keep the change intentional and minimal
  • document it if it affects setup, workflow, or contributor experience
  • update relevant config or docs when needed
  • avoid destructive or high-impact system changes unless explicitly requested
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.
