TabzChrome AGENTS.md

TabzChrome AGENTS.md is an instructions file for Codex, OpenCode from GGPrompts/TabzChrome. It costs 427 tokens per session, scanned A, original, MIT.

A project instruction file for GGPrompts and TabzChrome, covering the codebase, development rules, build and test commands, and documentation practices. The project includes a Chrome side panel, a Node.js backend, and an MCP server.

In plain words
What is it for?
It is for guiding development, specifying how to build and test the project, managing tracked work with ggbd, and recording user-visible changes or lessons learned.
Why use it?
It gives coding agents shared context and rules, reducing the chance of breaking protocols, storage formats, platform support, or project routines.

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

TabzChrome 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 5d 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.

What it actually says

Agent Instructions

This project uses ggbd (beads) for issue tracking with a shared Supabase/Postgres backend.

Project Context

  • Chrome extension side panel + Node.js backend + MCP server
  • Backend runs on localhost:8129 and uses tmux for sessions
  • Bash-only terminals; avoid adding other shell types

Development Rules

  • Keep it simple; avoid over-engineering
  • Cross-platform only: no hardcoded paths or OS-specific assumptions
  • Do not break WebSocket protocol or Chrome storage schema
  • Avoid adding new npm dependencies unless absolutely necessary

Build & Test

  • Use /rebuild to build the extension (do not use npm run build)
  • Start backend with ./scripts/dev.sh (or cd backend && npm start)
  • Run tests with npm test -- --run

Documentation Updates

  • Update CHANGELOG.md for user-visible changes
  • Add lessons to docs/lessons-learned/ for tricky bugs
  • Update CLAUDE.md only for architecture changes

Quick Reference

ggbd ready              # Find available work
ggbd show <id>          # View issue details
ggbd update <id> --status in_progress  # Claim work
ggbd close <id>         # Complete work
# Supabase auto-syncs (no manual sync needed)

Landing The Plane (When Shipping)

Only do this workflow when asked to land changes (commit/push), or when finishing a change that should clearly be published.

  1. File ggbd issues for follow-ups (only if needed)
  2. Run relevant quality gates (tests/linters/build) if applicable
  3. Update/close ggbd issue(s) if used
  4. Publish:
    git pull --rebase
    git push
    git status  # should show "up to date with origin"
    
  5. Hand off: brief context for next session

If not shipping, leave a clear handoff summary instead.

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.
