ai-cortex AGENTS.md

ai-cortex AGENTS.md is an instructions file for Codex, OpenCode from ai-creed/ai-cortex. It costs 1,122 tokens per session, scanned B, original, MIT.

A set of project instructions for ai-cortex, a local tool that helps coding agents understand a codebase, remember past work, and find relevant files. It also defines where the project’s plans, decisions, and stored data belong.

In plain words
What is it for?
Use it when working on ai-cortex or when an agent needs guidance on project structure, source-of-truth documents, local plans, memory, and stored session information.
Why use it?
It gives an agent consistent rules for navigating and changing the project. This reduces confusion about the repository layout, trusted documentation, and where persistent data may be written.

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 B, and why

ai-cortex AGENTS.md scanned grade B 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 4d 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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

- Hook installation under `~/.claude/settings.json` and `~/.codex/config.toml` is the explicit exception — those are user-owned config (not repo-owned), and the user opts in via `ai-cortex history install-hooks`.

Project Summary

  • ai-cortex is a local-first intelligence layer for AI agents — fast project rehydration, file discovery, call-graph awareness, captured session history, and a memory layer that records project rules and surfaces them at edit time.
  • Architecture is three-layer: structural (rehydrate / suggest / blast-radius), continuity (history + memory), and integration (MCP + briefing + adoption tooling).
  • All persistent state lives under ~/.cache/ai-cortex/. ai-cortex MUST NOT write to user repository files.

Source Of Truth

  • Tracked architecture and product decisions live in docs/superpowers/specs/.
  • Local execution plans live in docs/superpowers/plans/.
  • docs/superpowers/plans/ is git-ignored and local-only. Do not commit or re-track files from that directory.
  • User-facing docs: README.md plus the curated hierarchy under docs/ (getting-started, concepts, guides, reference, architecture, and roadmap).

Repo Layout

  • src/cli.ts: CLI entrypoint.
  • src/version.ts: canonical version source. Kept in lockstep with package.json by scripts/release.sh.
  • src/lib/: core library (indexer, retrievers, briefing, update-notifier, migration-notifier).
  • src/lib/history/: session-history capture + hook installation.
  • src/lib/memory/: memory layer (lifecycle, recall, scope match, surface hook, briefing digests).
  • src/lib/stats/: telemetry sinks + readers used by the stats TUI and CLI report.
  • src/mcp/server.ts: MCP server with the agent-facing tool surface.
  • tests/unit/, tests/integration/: vitest test suites.
  • scripts/release.sh, scripts/lib/release-headline.ts: release tooling.

Memory Layer Self-Use

  • This project uses its own memory layer. Project-scoped memories surface during edits via the PreToolUse hook and the rehydration briefing.
  • Do not put scars, gotchas, or recurring lessons in this file. Record them as memories via record_memory so they surface only when relevant (and don't bloat every agent's context).
  • Cardinal pattern: recall_memory is browse-only and does not signal usage; get_memory(id) is the consult signal that drives cleanup eligibility.

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.
