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

my-pi 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 19d 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.

AGENTS.md

Guidance for coding agents working in this repository.

Orientation

This repo is my-pi: a curated Pi coding-agent distribution plus reusable @spences10/pi-* packages.

Start with:

  • README.md for distribution-level usage and package list.
  • docs/package-map.md for installable vs support packages.
  • docs/agent-workflows.md for repository-specific skill routing.
  • docs/dependency-overrides.md before changing pnpm overrides.
  • Package-local README.md files before changing package behavior or user-facing docs.

Repository-specific skills

Project skills live directly under .agents/<skill>/SKILL.md. Load the matching skill before doing the work:

Task Skill
Build or modify Pi extensions/packages pi-extension-development
Compare proposed customisation with Pi built-ins pi-primitive-check
Prepare or validate releases pi-release-workflow
Run review-gated peer issue delivery pi-review-gated-delivery
Develop or review the observability dashboard pi-observability-local-dev
Test published package installability pi-package-sandbox-test
Validate repository edits pi-validation-flow

Keep skill metadata activation-friendly:

  • single-line description
  • # prettier-ignore above long descriptions
  • trigger language starts with Use when...
  • validate with pnpx check-skills validate .agents --recursive --json

Source of truth order

  1. Package-local README.md files for user-facing package behavior.
  2. .agents/*/SKILL.md files for agent operating procedure.
  3. Root README.md for distribution positioning and commands.
  4. Source/tests for implementation details when docs are incomplete.

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.
