dotfiles: Instructions file for Codex

AGENTS.md

dotfiles AGENTS.md is an instructions file for Codex, OpenCode from brujack/dotfiles. It costs 387 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for maintaining a dotfiles project, a collection of personal configuration files. They define the authoritative documentation, editing requirements, validation commands, and cleanup rules.

In plain words
What is it for?
Use them before editing to read the required guidance, follow repository standards, run lint and tests, update related documentation, and complete the specified Git cleanup after merging.
Why use it?
They give coding agents a single source of truth and reduce inconsistent changes, missed checks, and leftover branches or worktrees.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions AGENTS.md.

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

dotfiles 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 2mo 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

AGENTS.md

Cursor agent instructions for this repo.

Source of truth (exhaustive)

  • CLAUDE.md is exhaustive and authoritative for this repository.
  • Treat all rules in CLAUDE.md as required, not advisory.
  • If this file and CLAUDE.md conflict, follow CLAUDE.md.
  • Also apply global Cursor rules from ~/.cursor/rules/ when they do not conflict.

Required compliance behavior

  • Before editing, read relevant sections in CLAUDE.md.
  • During implementation, follow the repository's exact standards for shell style, idempotency, install guards, profile/capability usage, and symlink strategy.
  • After changes, run the validations required by CLAUDE.md (make lint, make test, and targeted suites as applicable).
  • Keep docs in sync when required by CLAUDE.md (including README.md and CLAUDE.md updates).

Dotfiles-specific must-follow items

  • After a feature PR merges: always complete post-merge cleanup — remove any linked worktree for that branch, delete the branch locally and on origin, then git fetch --prune and git pull on master. See ~/.claude/standards/git-workflow.md (Feature Branches step 5).
  • Preserve selective Cursor user linking: only settings.json, keybindings.json, and snippets from .cursor/User.
  • Do not introduce broad linking of volatile/local editor state.
  • Preserve pre-commit and pre-push hook behavior and CI conventions.
  • Never commit local-only state or secrets (for example config/local.sh, credentials, tokens, or machine-local caches).

Drift control

  • When CLAUDE.md changes, update this file in the same change so both remain aligned.
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.
