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 | $0.00861 | $0.00861 |
| Opus 5.5 | $0.00344 | $0.00344 |
| Sonnet 5.5 | $0.00172 | $0.00172 |
| Haiku 4.5 | $0.00086 | $0.00086 |
Grade A, and why
.context 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 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.
How it starts
The opening of the file, as written. The whole thing — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md (For AI Tools Other Than Claude Code)
Research-backed entry point. Research: .context/research.md. Full methodology: .context/substrate.md.
Claude Code reads CLAUDE.md automatically. This file is for Cursor, GitHub Copilot, Windsurf, ChatGPT, and any other AI tool.
Always loaded
Two files, every time:
.context/ai-rules.md: project-wide hard constraints.context/glossary.md: terminology
Path-scoped rules
Load only when touching matching files. Full rule files live in .claude/rules/.
This table mirrors CLAUDE.md. That file is the source of truth. Keep the two in sync.
When a file matches multiple rows, load every matching rule file.
| Touching | Rule file |
|---|---|
src/api/**, src/routes/**, src/handlers/**, app/api/** |
.claude/rules/api.md |
src/auth/**, src/middleware/auth*, src/security/** |
.claude/rules/auth.md |
src/models/**, src/db/**, src/repositories/**, migrations/**, *.sql |
.claude/rules/database.md |
src/components/**, app/** (non-page), *.tsx, *.jsx, *.vue, *.svelte |
.claude/rules/ui.md |
src/app/**/page.*, src/pages/**, public/sitemap*, public/robots*, src/head/** |
.claude/rules/seo.md |
**/*.test.*, **/*.spec.*, tests/**, __tests__/** |
.claude/rules/testing.md |
Tool-specific wiring
Cursor
.cursor/rules/ with globs: frontmatter. Example:
# .cursor/rules/api.mdc
---
description: API development patterns
globs: src/api/**,src/routes/**,src/handlers/**,app/api/**
---
@.claude/rules/api.md
Repeat for each rule in the table above.
GitHub Copilot
Create .github/copilot-instructions.md for the always-loaded set:
Follow rules in .context/ai-rules.md.
Use terminology from .context/glossary.md.
For path-scoped rules, create .github/instructions/<domain>.instructions.md with applyTo: frontmatter pointing at the matching rule file.
Windsurf
.windsurfrules is not path-aware. Keep it tight. Reference the always-loaded set and the most commonly used rule file for this project:
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.
- 2mo ago First seen · 88 lines · 861 tokens per session scan A 2efa40b33bdc
.context AGENTS.md is an instructions file published in the GitHub repository andrefigueira/.context (252 stars, last pushed 6mo ago), licensed MIT. It adds 861 tokens to every session, about $0.0034 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
