shine: Instructions file for Codex

AGENTS.md

shine AGENTS.md is an instructions file for Codex, OpenCode from biulight/shine. It costs 1,580 tokens per session, scanned A, original, MIT.

Repository instructions for Shine, a self-contained Rust command-line tool that installs shell scripts, app settings, and operating-system setup files.

In plain words
What is it for?
Use them when changing Shine’s Rust code, documentation, installation process, or uninstall behavior.
Why use it?
They tell coding agents what to read before changing code and where to record design decisions, lessons, and architecture changes.

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

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

shine 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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 109 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

shine bundles shell, app, and OS bootstrap presets into a Rust CLI with manifest-tracked installation and uninstall. The root package is shine-cli (sources in cli/); core/ is shine-core. Keep this entry point focused on repository rules; route details to the KB.

Workflow and authorization

  • Complete authorized edits and verification using context for routine choices. Ask only when missing information changes the outcome or an action needs authorization not already given; continue independent work while resolving it.
  • User instructions take precedence over skill workflow preferences. Skills and command examples do not grant permission to push, activate presets, execute external code, or bypass Shine's ownership, trust, and snapshot-bound approval checks. If an instruction blocks work, cite its file and exact requirement and explain what remains blocked.
  • Preserve unrelated working-tree changes; do not overwrite or clean files you do not own.
  • Before a non-trivial change, read the relevant sections of invariants and search lessons for the affected behavior. Check ADRs before proposing a design; consult data flows for changes spanning modules.
  • Refactoring must reduce total maintenance cost while preserving behavior and safety boundaries. Prefer deletion and direct local code; fewer files, less duplication or more tests alone do not establish value. Count production, tests/support and docs separately, retain independent risk coverage, and follow the refactoring review gates.
  • Update stale KB material in the same change using the maintenance protocol.

Hard repository rules

  • Never run git push without explicit user approval, including branch, tag, and force pushes. A request to commit is not permission to push; retain approval already given for the same action.
  • Work lands on release; main receives only automated post-release sync PRs (ADR 0001).
  • CHANGELOG.md is hand-written. Never generate it with git cliff; the release workflow uses git-cliff only for the GitHub Release body.
  • Version decisions use the latest stable v* tag, never the moving preview tag; follow versioning conventions.
  • Internal fixes caused by new code in the same release use the git-cliff-skipped scopes in commit conventions. Real user-facing fixes use their feature area.
  • User-visible behavior changes must update both public manual locales in the same release change: docs/manual/ and website/i18n/zh-Hans/docusaurus-plugin-content-docs/current/. Keep doc IDs, page sets, commands, identifiers, examples, and warnings semantically aligned.
  • Never publish docs/kb/, PRDs, release runbooks, private paths, or internal procedures through the public site. Root READMEs are summaries, not a second command/configuration reference.

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.
