plannable AGENTS.md

A guide for Plannable, a command-driven planning tool for AI coding agents.

In plain words
What is it for?
Use it to create and run project plans, track progress, record evidence, and maintain Plannable’s planning files.
Why use it?
It keeps plans compact and verifiable by using small files, concrete evidence, and honest descriptions of which commands each platform supports.

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

plannable 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.

What it actually says

AGENTS.md

Plannable is a command-driven planning skill and CLI for AI coding agents.

Agent Rules

  • This repo builds Plannable.
  • Keep files small and agent-readable.
  • Prefer examples over abstract theory.
  • Do not create giant Markdown documents.
  • Keep the human-facing plan short and scenario driven in MASTER_PLAN.md.
  • Keep .ai.md files compressed but semantically readable.
  • Load only one compressed plans/PART*_PLAN.ai.md file at a time.
  • All .ai.md plan parts must start with @PlannablePlan v0.1.
  • Do not call the compressed format PlanPack.
  • Use PlannablePlan as the format name.
  • Refer to domain-specific generation nudges as scenario hints, not presets or product templates.
  • Do not use binary/base64/gzip as the default planning format.
  • Mark a part complete only after adding evidence to PLAN_EVIDENCE.md.
  • Prefer concrete verification artifacts: tests, screenshots, command output, changed file paths, or manual QA notes.
  • Do not promise exact slash-command support where the platform does not support it.
  • Be honest about platform-specific launchers.

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.
