forge: Instructions file for Codex

AGENTS.md

forge AGENTS.md is an instructions file for Codex, OpenCode from harshanandak/forge. It costs 491 tokens per session, scanned A, original, MIT.

A project instruction set for Forge, a coding-agent workflow system. It defines a test-first process, automatic skill selection, and rules for classifying changes.

In plain words
What is it for?
Following project workflows, choosing relevant skills, running staged changes, and applying stricter checks to critical work.
Why use it?
It gives the agent a consistent way to plan and carry out code changes, while making important workflow steps explicit.

Instructions file for CodexOpenCode

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

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

forge 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.

What it actually says

Forge

Forge (npm package forge-workflow, command forge) is an open building-block platform for AI coding agents. Blocks declare their operations once; the CLI and MCP tools are generated from that catalog. Core knows no workflow: stages, TDD and pull requests live in blocks and templates. Bun builds Forge; the published package runs on Node 24.15 or later 24.x, or Node 26 and later (Node 25 is not supported) with npm and assumes nothing about a user's toolchain.

Commands: package.json scripts. test/structure holds repo guards. Agents: use forge <noun> <verb> --help --json or forge catalog describe <noun.verb> for the full JSON contract.

Gotchas

  • bun lint needs canary; bun fmt is stable in 1.4.4. The lint and fmt scripts use tools/bun-builtin.ts, which exits 1 with an upgrade hint on a Bun without the built-in. bun check needs Bun 1.4.3 or newer.
  • CI is the gate and there are no local git hooks. Run what you touched locally; the full matrix runs on the pull request. Fix the cause of a failing check; never skip one with --no-verify or core.hooksPath tricks.
  • Work in a git worktree under .worktrees/, based on the fetched origin/main.
  • Commit with conventional titles (feat:, fix:, docs:, chore:, refactor:, test:, ci:). The pull request title is checked and becomes the squash-merge title and the changelog line.
  • After cloning, run forge skills sync. People run /forge-loop; models read .agents/skills/forge-loop/SKILL.md when told to.
  • Checks: PASS exits 0; FAIL 1; INCOMPLETE/NOT_EXECUTED 2. Non-PASS keeps the receipt with ok:false.

Standards

Read CODING_STANDARDS.md before writing or reviewing code, adding a dependency, adding a test, or retiring something. It holds the boundaries, dependency, test and platform rules; most are enforced by a guard in test/structure.

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.
