nubecita: Instructions file for Codex

AGENTS.md

nubecita AGENTS.md is an instructions file for Codex, OpenCode from kikin81/nubecita. It costs 654 tokens per session, scanned C, a copy of Axiom AGENTS.md, MIT.

Project instructions for Nubecita that define shell-command conventions and the use of beads, a lightweight issue tracker. They include non-interactive forms of common file and remote commands.

In plain words
What is it for?
Use them when running file operations, SSH or package commands, recursive copies or removals, or when finding, claiming, updating, and closing project issues.
Why use it?
They reduce the risk of development commands hanging for confirmation and keep issue-tracking work aligned with the repository's process.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: names the TodoWrite tool.

This is kikin81/nubecita's own configuration. It tells Codex and OpenCode how to work on nubecita 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 nubecita 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 C, and why

nubecita AGENTS.md scanned grade C 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 8d 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

rm -rf directory # NOT: rm -r directory

This is a copy

80% identical to Axiom AGENTS.md — 51 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

Non-Interactive Shell Commands

ALWAYS use non-interactive flags with file operations to avoid hanging on confirmation prompts.

Shell commands like cp, mv, and rm may be aliased to include -i (interactive) mode on some systems, causing the agent to hang indefinitely waiting for y/n input.

Use these forms instead:

# Force overwrite without prompting
cp -f source dest           # NOT: cp source dest
mv -f source dest           # NOT: mv source dest
rm -f file                  # NOT: rm file

# For recursive operations
rm -rf directory            # NOT: rm -r directory
cp -rf source dest          # NOT: cp -r source dest

Other commands that may prompt:

  • scp - use -o BatchMode=yes for non-interactive
  • ssh - use -o BatchMode=yes to fail instead of prompting
  • apt-get - use -y flag
  • brew - use HOMEBREW_NO_AUTO_UPDATE=1 env var

Beads Issue Tracker

This project uses bd (beads) for issue tracking. Run bd prime to see full workflow context and commands.

Quick Reference

bd ready              # Find available work
bd show <id>          # View issue details
bd update <id> --claim  # Claim work
bd close <id>         # Complete work

Rules

  • Use bd for ALL task tracking — do NOT use TodoWrite, TaskCreate, or markdown TODO lists
  • Run bd prime for detailed command reference and session close protocol
  • Use bd remember for persistent knowledge — do NOT use MEMORY.md files

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 push
    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

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.
