What is Intent CLAUDE.md?

A project instruction file for Intent, a Git-based tool that records why code changes were made alongside the code itself. It documents the project structure, technologies, dependencies, and the format of its .intent/ folder.

Use it as guidance when working in the TypeScript monorepo, especially when editing the schemas, core, command-line, or MCP packages and their tests.

It gives people and coding agents shared context about the project and its architectural boundaries before they make changes.

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	$0.02562	$0.02562
Opus 5.5	$0.01025	$0.01025
Sonnet 5.5	$0.00512	$0.00512
Haiku 4.5	$0.00256	$0.00256

Security

Grade A, and why

Intent CLAUDE.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 2mo 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.

Intent — Claude Code Context

What this project is

Intent is a Git-native reasoning layer for software projects. It lives inside the repo as .intent/ and tracks the why behind code: plans, architectural decisions, constraints, and system context. It's designed to be read by both humans and AI agents.

The core idea: Git already tracks what changed. Intent tracks why it changed.

Monorepo structure

packages/
  schemas/   — Zod schemas and TypeScript types for the .intent/ format (no deps on other packages)
  core/      — All .intent/ file I/O, parsing, and git integration (depends on schemas)
  cli/       — Commander-based CLI (depends on core, thin layer — no business logic here)
  mcp/       — MCP server exposing Intent tools to AI agents (depends on core)
apps/
  web/       — Hosted dashboard (future)

Dependency rule: schemas → core → cli/mcp. Never import cli into core. Never import core into schemas.

Tech stack

TypeScript (strict, NodeNext modules)
pnpm workspaces + Turborepo
Zod for all schema validation
Vitest for tests
Commander for CLI
simple-git for git integration
gray-matter for frontmatter parsing

The .intent/ format

Every .intent/ file uses hybrid frontmatter markdown: structured YAML frontmatter + free-form markdown body. The YAML is the contract; the body is the reasoning.

Example plan file (.intent/plans/subscriptions.md):

---
id: plan-subscriptions
title: Marketplace subscription tiers
type: plan
status: active
created: 2024-01-01T00:00:00Z
updated: 2024-01-01T00:00:00Z
system: marketplace
decisions: [DEC-0001]
constraints: []
tags: [monetisation, marketplace]
---

## Goal
Add subscription tiers to the marketplace.

## Reason
Need monetisation while keeping core collecting accessible.

## Rules
- Free users: 5 listings
- Vendor users: unlimited listings

The only pure-JSON file is .intent/intent.json (project config). Auto-generated indexes live in .intent/links/ — never edit these manually.

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.
