agent-feed: Instructions file for Codex

AGENTS.md

agent-feed AGENTS.md is an instructions file for Codex, OpenCode from fqmyysjjd/agent-feed. It costs 1,945 tokens per session, scanned A, original, MIT.

A repository guide for AI-assisted development. It tells coding agents how to enter the project, choose which instructions to follow, and know when the task is complete.

In plain words
What is it for?
Use it when configuring an AI coding agent to work in the agent-feed repository, especially at the start of a new session or task.
Why use it?
It prevents an agent from missing important project rules or loading the wrong guidance. It also separates startup instructions from detailed workflows.

Instructions file for CodexOpenCode

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

This is fqmyysjjd/agent-feed's own configuration. It tells Codex and OpenCode how to work on agent-feed 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 agent-feed 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

agent-feed 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.

agent-feed AI Development Instructions

AGENTS.md is the repository-level entry contract for AI-assisted development.

It defines how an AI assistant should enter the project, resolve rule priority, route work to the right .agents/ asset, and stop when the requested result is reached. It is not a product specification, user-facing behavior rule, or a place for detailed workflows.

Startup Policy

Use full startup only when the AI session is new, context compression occurred or is suspected, the current task boundary cannot be recovered, or the task shifts into design, implementation, fix, review, or protocol work.

For same-session continuation with a clear task boundary, use the light resume path in .agents/rules/context-loading.md: re-read .agents/rules/outcome-boundary.md, then load only the rule, project, domain, or skill file needed for the next action.

During full startup, read:

  1. .agents/rules/outcome-boundary.md
  2. .agents/rules/decision-gates.md
  3. .agents/rules/context-loading.md
  4. .agents/rules/session-state.md
  5. .agents/rules/testing-gates.md
  6. .agents/README.md
  7. .agents/skills/README.md
  8. .agents/project/README.md
  9. .agents/domain/README.md
  10. .agents/skills/project-architecture/SKILL.md
  11. .agents/skills/project-development/SKILL.md

Before continuing any design, implementation, review, or fix task, recover the current task result boundary and Task Brief from .agents/rules/outcome-boundary.md.

For long-running or multi-turn work, read or update .agents/session-state/<session_id>.json according to .agents/rules/session-state.md when losing active conclusions could dilute direction, constraints, or next actions after context compression.

Rule Priority

Apply guidance in this order:

  1. Current user request and confirmed task boundary, after reconciling them with non-negotiable project constraints.
  2. .agents/rules/outcome-boundary.md.
  3. .agents/rules/decision-gates.md for unconfirmed choices that affect future results.
  4. .agents/rules/context-loading.md and .agents/rules/session-state.md.
  5. .agents/rules/testing-gates.md for verification and test evidence.
  6. Other stable rules under .agents/rules/.
  7. User-maintained repository-specific constraints indexed by .agents/project/README.md.
  8. Stable domain context under .agents/domain/.
  9. Task workflows indexed by .agents/skills/README.md and implemented under .agents/skills/.
  10. Protocol helper scripts under .agents/scripts/.
  11. Optional specialist profiles under .agents/agents/.

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.
