grainulator: Instructions file for Codex

AGENTS.md

grainulator AGENTS.md is an instructions file for Codex, OpenCode from grainulation/grainulator. It costs 463 tokens per session, scanned A, original, MIT.

Project instructions for the Grainulator workspace, covering task scope, sprint directories, source provenance, testing, previews, and release permissions. A sprint is a focused period or work area for a set of tasks.

In plain words
What is it for?
It is for guiding repository work, running component and runtime tests, previewing the site, and managing authorized releases.
Why use it?
It prevents edits from going into the wrong work area and separates testing, publishing, and release actions that need explicit approval.

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

grainulator 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 today.

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 — 18 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Grainulator workspace

This is the Grainulator source checkout. Follow the user’s active scope for local edits, branch pushes, deployment, publication, and repository archival. Do not create a release tag or publish a release before the required CI checks pass; those actions must also be covered by the user’s release authorization. The root npm package and component workspaces remain private; a GitHub release does not authorize npm publication.

Use the active sprint directory identified by the current task or project instructions. If none exists, create a dedicated sprint for the requested work; never repurpose an unrelated ledger. Pass --dir or the MCP dir argument explicitly. Use skills/grainulator/SKILL.md for the portable workflow.

Source imports and local-edit provenance live in docs/source-imports.json. Do not overwrite original checkouts. Retained package names are compatibility aliases; package directories describe responsibilities.

Run npm test for component suites and dogfood regressions. Run node test/conformance.mjs from packages/runtime for Rust runtime conformance. Use npm run dev for site previews; validate responsive and keyboard behavior before handing off visual changes.

The permission dashboard and its connectors have been removed at the maintainer’s request. Do not restore that application, its hooks, or its runtime dependencies. Native hosts own permissions and remote access. Generated evidence and analytics reports remain supported.

Next-step output

After a meaningful pass, use the current compiler's next_actions to present exactly two bullet lists labeled Auto and Manual. Auto is work the agent can continue under existing authorization. Manual is only work requiring the user's decision, access, or action. Classify using the current request and constraints; compiler suggestions never grant permission. Continue authorized Auto work without asking again.

Keep 2–3 useful actions total when available, use short concrete labels and commands where useful, and show None. for an empty group. Do not invent work to fill a quota. Never omit next steps merely because compilation is ready or the answer should be brief. Refresh stale compilation first and exclude work the user removed from scope. When the user asks only for next steps, output only these two lists: no findings recap, counts, reasons, or offer to continue.

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.
