GocciaScript: Instructions file for Codex

AGENTS.md

GocciaScript AGENTS.md is an instructions file for Codex, OpenCode from frostney/GocciaScript. It costs 1,393 tokens per session, scanned A, original, MIT.

Repository instructions for GocciaScript, a programming language project, aimed at AI coding assistants. They explain which contribution guide to read, how to follow project conventions, and which checks to run.

In plain words
What is it for?
They are for navigating the project, reading its contribution requirements, following its code style, and verifying edits with tests or formatting checks.
Why use it?
They help an assistant make changes that match the repository’s rules instead of relying on generic coding habits.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions Claude Code; mentions AGENTS.md.

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

GocciaScript 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 5d 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.

Contributing guide vs this file

Purpose
CONTRIBUTING.md Contributing guide for all contributors—humans and agents. Workflow, critical rules, testing, Pascal code style, formatting, build/run reference, documentation index. If it affects what may be merged, it belongs there.
This file (AGENTS.md; CLAUDE.md imports it) Agent-only context: how assistants should operate in this repo, where to read first, and what not to duplicate. It does not replace CONTRIBUTING.

Assistants should treat CONTRIBUTING as authoritative for contribution requirements. Use this file for assistant-specific expectations and navigation, not a second copy of CONTRIBUTING.

Expectations for assistants

  • Follow the known-good-route operating loop for repository work. A defect in its skills or helpers is fixed upstream in known-good-route, not worked around here.
  • Vendored vs repo-native skills: skills listed in skills-lock.json are vendored by the skills CLI. Never hand-edit them; fix them upstream (known-good-route for its skills). Edit a repo-native skill (prepare-release, gocciascript-issue-validation, optimize-runtime, profile-report-review) only when the user asks to change that skill.
  • Infer architecture boundaries during planning: when a change touches website routes, API handlers, generated reports, external services, credentials, artifacts, caches, CI outputs, or deployment/build steps, identify where the work belongs (build time, request time, client time, CI/scheduled time) and compare against existing project patterns before implementing. Do not rely on the user or a skill checklist to spell this out.
  • Search the real source layout: when prompts, automations, or audits search this repo, target source/units, source/shared, source/app, tests, scripts, and website/src explicitly. Do not assume a generic root src/ tree; source/generated is generated data and should only be inspected or regenerated when the task specifically requires it.
  • Do source deep-dives before policy claims: follow the investigation discipline. For ECMAScript the normative source is ECMA-262/ECMA-402 (see TC39 spec lookup); classify each surface as shim-, parser-, runtime-, or object-model-level by the mechanism it needs.
  • Cap memory for depth, fuzz and exponential probes: run them through scripts/depth-probe.ts, which caps every probe process's memory and time, or wrap an ad-hoc run as systemd-run --user --scope -q -p MemoryMax=3G -p MemorySwapMax=0 -- timeout 120 <command>. Uncapped probes have grown a runner to 27 GB and set off the host's OOM killer. See Tooling — Depth and Fuzz Probe.
  • Clean first for stale FPC failures: after a merge, branch switch, PR sync, generated resource change, or unexplained compiler/resource error, retry with ./build.pas --clean <target> (or ./build.pas --clean) before diagnosing the reported source line. See Tooling — Stale FPC Build Artifacts.

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.
