FrontAgent: Instructions file for Codex

AGENTS.md

FrontAgent AGENTS.md is an instructions file for Codex, OpenCode from ceilf6/FrontAgent. It costs 1,175 tokens per session, scanned A, original, MIT.

A set of project instructions for FrontAgent, an open-source coding harness. It explains which documents define the project, how to handle changes, and how to check their impact.

In plain words
What is it for?
Use it when contributing to FrontAgent: prepare the project, review a change’s impact, keep edits focused, run tests, and inspect the final diff.
Why use it?
It reduces guesswork when project documents disagree or a code change may affect other parts of the project. It also sets checks to run before and after editing.

Instructions file for CodexOpenCode

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

This is ceilf6/FrontAgent's own configuration. It tells Codex and OpenCode how to work on FrontAgent 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 FrontAgent 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

FrontAgent 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.

FrontAgent OSS Harness

Documents

  1. README.md is the public product and command overview.
  2. docs/architecture.md and docs/design.md define architecture and SDD behavior.
  3. CONTRIBUTING.md, docs/workflow.md, and docs/knowledge-contract.md define OSS contribution, Harness, and GitNexus contract rules.
  4. Issue or PR text defines the specific change request.
  5. Existing code is evidence, but it does not override the documents above.

When documents conflict or expected behavior is unclear, ask the maintainer instead of silently choosing a new architecture.

Work

  1. Run pnpm agent:bootstrap and pnpm quality:predev before code changes when feasible.
  2. Before editing a function, class, or method, run GitNexus impact analysis and report the blast radius.
  3. Keep changes focused and independently reviewable.
  4. Run focused tests for the touched area, then broader gates as risk increases.
  5. Before final review, run pnpm quality:precommit at minimum and use GitNexus detect_changes to inspect the final diff.
  6. For critical skeleton changes, fill the PR GitNexus impact summary with concrete detect_changes plus query, context, or impact results.

Harness Loop

For non-trivial repository changes, use this loop:

  1. Start from an Issue, Discussion, or maintainer-approved task description.
  2. Create a short-lived branch from develop using feat/, fix/, docs/, or chore/.
  3. Run pnpm agent:bootstrap and pnpm quality:predev.
  4. Implement the smallest reviewable change with focused tests.
  5. Run pnpm quality:local before pushing when feasible.
  6. Open a PR to develop with the PR template filled in, including the GitNexus impact summary for critical skeleton changes.
  7. Wait for GitHub Actions, Contract Guard, Repo Guard, Codex, Copilot, and maintainer review comments.
  8. Address actionable review comments with follow-up commits, then rerun the relevant gates.
  9. Let maintainers decide merge readiness; do not add comment-triggered auto-merge behavior.

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.
