apex-workflow: Instructions file for Codex

AGENTS.md

apex-workflow AGENTS.md is an instructions file for Codex, OpenCode from 0xCozart/apex-workflow. It costs 535 tokens per session, scanned A, original, MIT.

Repository instructions for Apex Workflow, an installable harness that coordinates coding-agent work in an app repository. They describe setup, codebase orientation, checks, and safeguards for multiple agents.

In plain words
What is it for?
Installing Apex Workflow in an app repository, choosing its trackers and verification tools, and keeping its generated configuration and instructions valid.
Why use it?
They reduce guesswork when installing the workflow and help prevent changes that ignore repository rules or collide with other agents.

Instructions file for CodexOpenCode

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

This is 0xCozart/apex-workflow's own configuration. It tells Codex and OpenCode how to work on apex-workflow 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 apex-workflow 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

apex-workflow 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.

Apex Workflow Agent Instructions

This repo is an installable workflow harness.

Read docs/CODEBASE_MAP.md for codebase orientation before searching broadly. Read CONTRIBUTING.md before modifying Apex Workflow itself; it defines shared surfaces, verification expectations, and parallel-agent collision rules for this repo.

When a user asks you to install or configure Apex Workflow for an app repo, do not stop at copying the skill. Configure the target repo with the harness installer.

Install Flow

  1. Identify the target app repo path.
  2. Inspect the target repo enough to choose tracker, GitNexus/code-intelligence, browser, verification, and profile review needs from repo evidence.
  3. Run the installer with explicit choices:
npm run init -- \
  --target=/path/to/app \
  --config-mode=custom \
  --tracker=linear \
  --tracker-team="Team Name" \
  --tracker-project="Project Name" \
  --code-intelligence=gitnexus-mcp \
  --browser=agent-browser \
  --origin=http://127.0.0.1:3000 \
  --yes

The installer writes apex.workflow.json, creates or updates a managed Apex block in AGENTS.md, validates the generated profile, and symlinks the local skill into the Codex skills directory unless --skip-skill-link is passed.

After the install report prints, review inferred path confidence, adapter choices, dirty repo state, and baseline checkpoint guidance. Confirm or correct any setup.inferredPaths entries marked guessed before starting the first implementation slice.

Discovery is advisory only. Use --discover or apex-profile discover to collect candidate profile fields after explicit adapter choices are set, not as a replacement for repo-specific configuration judgment.

Guardrails

  • Do not overwrite an existing apex.workflow.json unless the user asked for a refresh or you pass --force intentionally.
  • Do not add Linear, GitNexus, browser automation, or design gates unless the target repo has them or the user chooses them.
  • Do not put human cautions in authority.doNotUseAsAuthority; use operatorCautions for security, public/private boundary, or secret-handling warnings.
  • Prefer GitNexus through MCP when the user chooses GitNexus. If MCP fails in the target environment, configure or document a repo-local wrapper fallback.
  • App-specific product truth belongs in the target repo profile, not in the generic Apex skill.

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.
