codemem: Instructions file for Codex

AGENTS.md

codemem AGENTS.md is an instructions file for Codex, OpenCode from kunickiaj/codemem. It costs 1,262 tokens per session, scanned A, original, MIT.

Project instructions for codemem, covering repository structure, where code runs, useful pnpm commands, build and test checks, and files that must stay out of version control.

In plain words
What is it for?
Use them when modifying codemem to locate the CLI, core, viewer, or plugin code, run installation/build/test commands, and follow repository-specific safety rules.
Why use it?
They help contributors work in the correct package, run the expected checks, and avoid committing private or generated files.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md; mentions OpenCode.

This is kunickiaj/codemem's own configuration. It tells Codex and OpenCode how to work on codemem itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything codemem configures →

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 A, and why

codemem 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 15d 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 — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.

codemem

  • Public repo: never add secrets, internal hostnames, private identifiers, or local artifact paths. Keep .tmp/, .venv/, *.sqlite, packages/*/dist/, packages/viewer-server/static/, and .opencode/package-lock.json out of git.
  • Default to the TypeScript toolchain: this repo is a pnpm workspace on Node 24; use the pnpm version pinned by the root packageManager field.

What runs where

  • CLI entrypoint: packages/cli/src/index.ts (pnpm run codemem ...).
  • Shared store/search/sync logic and exported version: packages/core/src/index.ts.
  • Viewer HTTP API + SPA host: packages/viewer-server/src/index.ts.
  • Viewer UI source: packages/ui/src/.
  • OpenCode plugin source of truth: packages/opencode-plugin/.opencode/plugins/codemem.js.
  • packages/cli/.opencode/plugins/codemem.js is a wrapper/re-export. The repo-root .opencode/plugins/codemem.js wraps only the V1 implementation and is an explicit V2 no-op to avoid colliding with a configured npm plugin.
  • packages/cloudflare-coordinator-worker/ is its own worker package with separate tests.

Commands worth using

  • Install: pnpm install
  • Full local gate / CI order: pnpm run tsc && pnpm run lint && pnpm run test (pnpm run check)
  • Build everything: pnpm run build
  • Run CLI from source: pnpm run codemem --help
  • Run one vitest file: pnpm exec vitest run packages/cli/src/commands/serve.test.ts
  • Run one package script: pnpm --filter codemem test, pnpm --filter @codemem/ui build, pnpm --filter @codemem/cloudflare-coordinator-worker test:worker
  • E2E smoke: CODEMEM_E2E_BUILD=1 CODEMEM_E2E_JSON=1 pnpm run e2e:smoke -- --json (artifacts land in .tmp/e2e-artifacts)

Gotchas agents usually miss

  • pnpm run lint only checks files included by biome.json (mostly packages/** TS/TSX/JS/JSON and root TS config). Docs like AGENTS.md are outside Biome.
  • pnpm run test is workspace vitest; root vitest.config.ts points at packages/*/vite.config.ts.
  • The viewer server throws if packages/viewer-server/static/index.html is missing. If you change UI or viewer assets, run pnpm build or at least pnpm --filter @codemem/ui build.
  • packages/viewer-server/static/ is generated and ignored. Do not hand-edit it. UI build stages packages/ui/static/ there alongside the built app.js bundle.
  • Plugin smoke tests rely on nested .opencode runtime deps. CI installs @opencode-ai/plugin inside packages/cli/.opencode and packages/opencode-plugin/.opencode before running smoke tests.
  • CLI work should follow docs/cli-design-conventions.md: max 2 nesting levels, noun-based groups, shared --db-path / --config / --json helpers, and no uncaught throws from command handlers.
  • The repo is TS-first; trust package.json, package scripts, and CI over older migration-era docs/checklists.
  • .github/PULL_REQUEST_TEMPLATE.md is TS-first now; use pnpm run tsc, pnpm run lint, and pnpm run test for normal 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.
