What is pi-mono AGENTS.md?

Repository instructions for pi-mono, a monorepo containing separately published Pi packages. A monorepo keeps multiple related packages in one repository, while each package can still have its own release rules.

Use them when changing a pi-mono package, especially when the change may affect other packages or repository-wide files. They also define required checks before publishing.

They explain which files and rules take priority before you edit code. They help prevent missed effects across packages, shared files, tests, releases, and CI.

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.

Model	Per session	Once invoked
Fable 5.1	$0.02114	$0.02114
Opus 5.5	$0.00846	$0.00846
Sonnet 5.5	$0.00423	$0.00423

Security

Grade A, and why

pi-mono 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 8d 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.

Repository Guidelines

Scope and precedence

pi-mono contains independently published Pi packages under packages/*.

Source of truth, highest first:

Executable config: package.json, tests, CI, release workflows.
Root AGENTS.md: monorepo invariants.
Package AGENTS.md: package-only invariants and exceptions.
README: user-facing product, setup, and usage.
CHANGELOG: released behavior.

Package instructions must not repeat root policy. If guidance conflicts with executable config, fix the stale guidance in the same change.

Required workflow

Read affected package AGENTS.md and inspect worktree/branch.
Map impact across package-local, cross-package, and root artifacts before editing.
Keep changes scoped; update tests with behavior.
Update user docs only when triggers below apply.
Run validation from the matrix.
Inspect git diff --check, git diff --stat, and packed files when publishing changes.

Impact scan includes root README/index, AGENTS.md, root manifest/lockfile, shared scripts/templates, workflows, release metadata, and security policy. Update only artifacts affected by the change; keep package listings, versions, commands, and policy synchronized.

Bug fixes require regression coverage of the broken integration path. Helper-only tests are insufficient when removing feature wiring would still pass. Private Pi API patches require render/contract tests and a documented smoke test when automation cannot cover runtime behavior.

Package contract

New packages should copy canonical config files from templates/package/, then add only needed resources (extensions/, skills/, prompts/, themes/). Every package requires:

package.json, tsconfig.json, .editorconfig, .gitignore
AGENTS.md, README.md, CHANGELOG.md
CODE_OF_CONDUCT.md, CONTRIBUTING.md, LICENSE, SECURITY.md

Do not publish tests, plans, agent files, generated builds, secrets, settings, or machine paths.

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.
