planner AGENTS.md

A set of instructions for an AI-first repository used to track project ideas, specifications, and research. It tells agents where to find the main index and the files for each project or idea.

In plain words
What is it for?
It helps agents resume projects, review ideas, read planning documents, and follow the repository's required workflow.
Why use it?
It gives agents a consistent way to understand the repository before continuing work, reducing missed context and incorrect starting points.

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

planner 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 2d 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.

Planning Repository — Agent Instructions (Universal)

This file provides instructions for non-Claude AI agents (Copilot, Cursor, Windsurf, etc.). For Claude Code, see CLAUDE.md which has richer, Claude-specific instructions including hooks and skills.

What This Repository Is

An AI-first planning repository for tracking project ideas, specs, and research. The user interacts exclusively through AI agents — they never read files directly.

Commands to Run First

# Always start by reading the master index
cat registry.yaml

# To resume a specific project
cat projects/<project-slug>/project.yaml
cat projects/<project-slug>/context.md

# To resume a specific idea
cat projects/<project-slug>/ideas/<NNN>-<slug>/session.md
cat projects/<project-slug>/ideas/<NNN>-<slug>/spec.md
cat projects/<project-slug>/ideas/<NNN>-<slug>/assumptions.md
# If the idea is implementing or coordinating execution
cat projects/<project-slug>/ideas/<NNN>-<slug>/IMPL_ORCHESTRATION_PLAN.md

Key Behaviors

Always Do

  • Read registry.yaml at the start of every session
  • Read session.md when resuming work on an idea — it contains full conversation state
  • Update session.md at the end of every session with progress, decisions, open questions, and next steps
  • Update registry.yaml when creating or changing the status of projects/ideas
  • Use templates from templates/ when scaffolding new projects or ideas
  • Cite sources in research.md — include URLs, file paths, commit hashes
  • For this planning repo itself, stay on the main branch unless the user explicitly asks for a different workflow
  • Make small, logical local commits as planning-repo changes develop to preserve iteration history and recovery points

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.
