What is trinity CLAUDE.md?

A set of contribution rules for Claude Code in the Trinity repository, including guidance for a public open-source project and its CLAUDE.md and AGENTS.md files.

Use it when contributing code to Trinity, checking repository rules, following its development process, or reviewing changes before committing.

It helps an coding agent understand which instructions apply to each task and avoid committing secrets, private URLs, or other unsafe content.

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	$0.06274	$0.06274
Opus 5.5	$0.02510	$0.02510
Sonnet 5.5	$0.01255	$0.01255
Haiku 4.5	$0.00627	$0.00627

Security

Grade A, and why

trinity CLAUDE.md scanned grade A with 1 finding 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 17d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 376 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md

This file provides guidance to Claude Code when working with this repository.

Repository: https://github.com/abilityai/trinity (PUBLIC)

AI agent orienting in this repo? AGENTS.md is the authoritative agent entry point — a task router with key facts, exact commands, and a "done when" check per task. This file is the contributor working agreement (Rules of Engagement, SDLC, architectural invariants), auto-loaded by Claude Code when you work on the codebase. Read it when your task is "contribute code"; start at AGENTS.md for deploy / operate / evaluate.

Core team: internal working-agreement context (current product focus, tracker routing, remote agent, methodology skill map) auto-loads via the import below from the private .claude submodule. On OSS clones without the submodule the import is silently skipped — everything an external contributor needs is in this file.

⚠️ PUBLIC OPEN SOURCE REPOSITORY

This is a PUBLIC open-source repository visible to the entire world.

What NEVER to Commit

❌ API keys, tokens, PATs, or any credentials (even in comments or docs)
❌ Internal company URLs, production domains, IP addresses
❌ Real user emails, personal information, or PII
❌ Database dumps, backups, or data exports
❌ .env files or deployment configs with real values
❌ Auth0 client secrets, OAuth credentials, or service account keys
❌ Private repository references or internal tooling details
❌ Customer names, company-specific configurations, or business data
❌ Enterprise/paid-feature designs — the catalog of which capabilities are gated behind the paid tier, their private schema (enterprise_* tables), per-module implementation, or the open-core monetization/gating rationale. Public docs describe the generic open-core seam only (the entitlement/registry mechanism and how OSS code conditionally registers private modules). Specific enterprise module designs live ONLY in the private trinity-enterprise repo (docs/memory/ENTERPRISE_DOCS.md there). See the standing rule below; a CI grep-guard (.github/workflows/enterprise-docs-guard.yml) flags regressions. (trinity-enterprise#45)

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.
