agentkernel: Instructions file for Codex

AGENTS.md

agentkernel AGENTS.md is an instructions file for Codex, OpenCode from thrashr888/agentkernel. It costs 1,269 tokens per session, scanned A, a copy of debugg-ai-mcp AGENTS.md, MIT.

A set of project instructions for coding agents working in AgentKernel. It explains how to track work with bd (Beads), a command-line issue tracker, and how to finish and hand over a coding session.

In plain words
What is it for?
Use it to find available issues, claim and close tasks, save issue changes, run checks, push code, clean up, and leave useful context for the next session.
Why use it?
It gives the agent a consistent process for recording unfinished work, checking quality, updating issues, and sending changes to the shared code repository. This reduces the chance that work is left untracked or unpublished.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is thrashr888/agentkernel's own configuration. It tells Codex and OpenCode how to work on agentkernel 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 agentkernel 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

agentkernel 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.

Origin

This is a copy

97% identical to debugg-ai-mcp AGENTS.md — 50 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Agent Instructions

This project uses bd (beads) for issue tracking. Run bd onboard to get started.

Quick Reference

bd ready              # Find available work
bd show <id>          # View issue details
bd update <id> --status in_progress  # Claim work
bd close <id>         # Complete work
bd dolt commit        # Persist pending bd changes to Dolt

Landing the Plane (Session Completion)

When ending a work session, you MUST complete ALL steps below. Work is NOT complete until git push succeeds.

MANDATORY WORKFLOW:

  1. File issues for remaining work - Create issues for anything that needs follow-up
  2. Run quality gates (if code changed) - Tests, linters, builds
  3. Update issue status - Close finished work, update in-progress items
  4. PUSH TO REMOTE - This is MANDATORY:
    git pull --rebase
    bd dolt commit
    bd dolt push  # If a Dolt remote is configured
    git push
    git status  # MUST show "up to date with origin"
    
  5. Clean up - Clear stashes, prune remote branches
  6. Verify - All changes committed AND pushed
  7. Hand off - Provide context for next session

CRITICAL RULES:

  • Work is NOT complete until git push succeeds
  • NEVER stop before pushing - that leaves work stranded locally
  • NEVER say "ready to push when you are" - YOU must push
  • If push fails, resolve and retry until it succeeds

Issue Tracking with bd (beads)

IMPORTANT: This project uses bd (beads) for ALL issue tracking. Do NOT use markdown TODOs, task lists, or other tracking methods.

Why bd?

  • Dependency-aware: Track blockers and relationships between issues
  • Git-friendly: Dolt-powered version control with native sync
  • Agent-optimized: JSON output, ready work detection, discovered-from links
  • Prevents duplicate tracking systems and confusion

Quick Start

Check for ready work:

bd ready --json

Create new issues:

bd create "Issue title" --description="Detailed context" -t bug|feature|task -p 0-4 --json
bd create "Issue title" --description="What this issue is about" -p 1 --deps discovered-from:bd-123 --json

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.
