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

This is alp82/aistack's own configuration. It tells Codex and OpenCode how to work on aistack 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 aistack configures →

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 A, and why

aistack 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 1mo 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.

The opening of the file, as written. The whole thing — 396 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AI Stack Webapp

This is a webapp for sharing AI Stacks so that users can compare and choose the best set of tools for their needs.

Development Process

  • Web App is running on localhost:3019 - I am taking care of the dev servers running properly in my own terminal
  • Convex is running already as well
  • Schema changes are often required and okay
  • Avoid backwards-compat, prefer convex migrations

Prod database access

Never point the local Convex CLI at prod. That broke the local setup multiple times. All prod operations run on the server over ssh ([email protected]). Two scripts wrap this:

# Any Convex CLI command against prod, executed on the server.
# The admin key is minted on the server per call and never stored here.
scripts/convex-prod.sh data models --limit 20
scripts/convex-prod.sh run migrations/<name>:run

# Replace the local dev database with a fresh prod export.
# Destructive locally (auth tables included - log in again). Prod is only read.
scripts/sync-prod-db.sh

The local database lags behind prod. Before work that depends on real rows (catalog data entry, migration dry runs), run scripts/sync-prod-db.sh first. It copies what prod HAS: for a reading no machine has published yet, see "Publishing a measured reading to the local backend".

Prod deploys run through GitHub Actions exclusively. A push to main triggers .github/workflows/deploy-convex.yml, which pulls the ~/aistack checkout on the server and runs pnpm convex deploy there. Never run npx convex deploy against prod from a local machine. To run a new migration on prod: push to main, wait for the workflow, then scripts/convex-prod.sh run migrations/<name>:run.

Never pass --push to scripts/convex-prod.sh, and never give it deploy, dev, or push. The CLI runs from a minimal project dir on the server that holds no convex/ directory, so anything that writes code pushes an EMPTY function set and prod loses every function and every index at once. That is a full outage, and it happened on 2026-08-24. The script now refuses those four forms, and the recovery is the workflow's own command, run on the server: ssh [email protected] "bash -l -c 'cd ~/aistack && git fetch origin main && git reset --hard origin/main && /root/.local/share/pnpm/pnpm i && /root/.local/share/pnpm/pnpm convex deploy'". Table rows survive; the indexes come back with the deploy.

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.
