documentation-criteria

documentation-criteria is a skill for Claude Code, Codex from shinpr/codex-workflows. It costs 44 tokens per session (1,099 once invoked), scanned A, original, MIT.

A documentation-planning guide that determines whether a change needs a product requirements document, architecture decision record, UI specification, design document, or work plan.

In plain words
What is it for?
Use it when assessing the size of a change, deciding documentation scope, or planning frontend, full-stack, or architecture-related work.
Why use it?
It helps teams choose the right documents and create them in the required order before implementation.

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

documentation-criteria 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 4d 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.

Documentation Creation Criteria

Templates

Creation Decision Matrix [MANDATORY]

Structural Scale Base Documents Creation Order
Small None N/A
Medium Design Doc -> Work Plan Start with Design Doc
Large PRD -> Design Doc -> Work Plan Continue after PRD approval

Build one path in this order:

  1. Select the base path from Structural Scale.
  2. Frontend or fullstack scope inserts UI Spec immediately before the Design Doc.
  3. One or more qualifying ADR decision points insert an ADR batch immediately before the Design Doc. A qualifying decision point sets the scale floor to Medium.

ENFORCEMENT: EVALUATE structural scale and ADR conditions BEFORE starting implementation

Structural Scale

Classify the decision burden, not repository layout. File count is supporting evidence only.

Scale Structural condition
Small One coherent outcome follows existing patterns within one responsibility boundary
Medium One coherent outcome coordinates across a boundary or requires a durable design decision
Large Multiple independently valuable outcomes require separate design decisions

A qualifying ADR decision point sets the floor at Medium because it creates a durable decision. Large applies when multiple independently valuable outcomes require separate design decisions; one coherent outcome remains Medium across multiple layers. ADR decision points come from the Choice and Durability filters independently of scale.

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.
