dev-workflow AGENTS.md

A set of workflow instructions for an AI coding agent, including how to resume work by reading the relevant CHANGELOG.md file. A monorepo is a repository that contains several related projects, so the instructions identify the changelog next to the files being changed.

In plain words
What is it for?
It helps resume interrupted tasks, organize multi-step changes, coordinate larger work, and run checks that confirm the result.
Why use it?
It preserves knowledge between sessions and prevents agents from repeating investigation or splitting project history across multiple changelogs. It also requires planning and verification before declaring work finished.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

dev-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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 206 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Agent Workflow Rules

Rules for any AI coding agent working in this repository (Codex, Gemini CLI, Cursor, Aider, Claude Code without the plugin, or any other). Follow them without being asked. They are tool-agnostic: no specific agent features are required, only the ability to read files, run commands, and follow instructions.

(If you are Claude Code with the dev-workflow plugin installed, the plugin already enforces these rules with hooks and subagents - this file is the fallback and the shared contract; the two never conflict.)

1. Session continuity (do this first, every session)

  • FIRST ACTION: locate and read the project's CHANGELOG.md. Check the current directory, then search downward (excluding node_modules/.git). In a monorepo, the changelog next to the files being edited is the project's memory - never create a second one at a higher level, which would split it.
    • The ## Current state block at the top says exactly where the last session stopped: what works, what's broken, the next step, open decisions, and known dead ends. Resume from it. Never re-explore or re-plan what it already answers.
    • If CHANGELOG.md does not exist, create it using the format in section 8 before any other work.
    • If it exists but has no ## Current state block, PREPEND the block (section 8 format) above the existing content. Never rewrite, reorder, or truncate existing history.
  • DURING WORK: append one entry per change, in the same turn the change is made. Never batch entries at session end. Entry format: file:line - before->after - why - verified how
  • BEFORE THE SESSION ENDS (including when blocked or interrupted): rewrite the ## Current state block so a fresh session with zero memory - yours or a different agent's - can continue from it alone.
  • Respect the DO NOT list: it records measured dead ends. Do not retry them.

2. Plan before code

For any non-trivial task (>~20 lines of change, >3 files, or any schema/ pipeline change): explore read-only first, then present a short plan and wait for approval before editing anything. The plan must contain:

  • Objective (one sentence)
  • Deliverable (exact file paths that will exist when done)
  • Approach (key decisions + one rejected alternative if non-obvious)
  • Risks/blockers (surface now, not mid-build)

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.
