openplan-garden

openplan-garden is a skill for Codex from BANANASJIM/openplan-skill. It costs 108 tokens per session (827 once invoked), scanned A, original, MIT.

A documentation review guide for OpenPlan-style projects. It checks whether goals, decisions, plans, evidence, and next actions remain understandable and current.

In plain words
What is it for?
Use it to inspect memory, specifications, design notes, handoffs, review reports, and generated documentation, then report problems that may need cleanup.
Why use it?
It helps reveal stale claims, duplicated information, missing reasoning, unclear sources of truth, and documents that only make sense with the original chat.

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

openplan-garden 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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.

OpenPlan Garden

Use this after $openplan-core for document quality, periodic documentation maintenance, and semantic drift inspection. Garden is about preserving the clarity of human goal/intent over time.

Core Rule

Garden first reports. It does not rewrite durable docs or memory unless the user explicitly asks for a cleanup/edit pass.

What Garden Checks

  1. Goal/intent clarity: can a future human or agent tell why this exists?
  2. Authority clarity: is this source of truth, draft, handoff, review, or temporary brief?
  3. Layer clarity: does it mix goal/intent, design, spec, implementation, and review without labels?
  4. Rationale: are decisions explained, not just stated?
  5. Staleness: are time-sensitive or superseded claims marked?
  6. Duplication: is content copied where a reference would work?
  7. Traceability: are important claims tied to sources or evidence?
  8. Zero-context readability: can a competent reader understand it without the chat?
  9. Human-decision boundary: does it record human decisions separately from agent suggestions?
  10. Next-action clarity: does it say what should happen next, if anything?

Periodic Garden Pass

Use garden as the periodic documentation cleanup workflow. A periodic pass checks:

  • stale or superseded documents;
  • duplicated rationale that should become references;
  • missing or unclear authority labels;
  • memory/docs conflicts;
  • abandoned TODOs or unresolved questions;
  • research/review/handoff artifacts that should be archived, promoted, or left alone;
  • docs that no longer pass zero-context comprehension.

Garden first reports proposed cleanup. It may edit only when the user explicitly asks for a cleanup pass, and durable goal/intent changes still require $openplan-record and human confirmation through the human-facing coordinator.

Workflow

  1. Identify document type: memory, design, decision, spec, handoff, review, tutorial, temporary brief.
  2. Identify the docs root when a whole documentation surface is being reviewed.
  3. Load only the document and directly referenced context needed to judge it.
  4. Run optional deterministic checks if available and safe.
  5. Apply references/checklist.md.
  6. Report findings using references/report-contract.md.
  7. If the user requests cleanup, use $openplan-record before editing durable memory/docs.
  8. For periodic maintenance, separate safe mechanical cleanup from human-owned meaning changes.

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.
