project-docs-prep

project-docs-prep is a skill for Claude Code, Codex from ntaffzii/Skill-Agents. It costs 218 tokens per session (1,180 once invoked), scanned A, original, MIT.

A documentation scaffold for software projects that prepares files describing what to build and how an AI coding agent should work in the repository.

In plain words
What is it for?
Preparing project specifications, system requirements, architecture notes, user-interface guidance, README files, and instruction files such as AGENTS.md or CLAUDE.md before coding begins.
Why use it?
It removes the need to organise project requirements, architecture, design guidance, and agent instructions from scratch. It also turns incomplete documentation into a clearer working set.

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

project-docs-prep 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.

How it starts

The opening of the file, as written. The whole thing — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Project Docs Prep

Turns a short project idea (or an existing incomplete docs folder) into a complete, AI-agent-ready documentation set. Produces two operational layers:

  1. Spec Layer (docs/) — describes what to build. Five numbered files:
    • 01-project-overview.md
    • 02-system-requirements.md
    • 03-tech-stack-architecture.md
    • 04-system-modeling.md
    • 05-ux-ui-design.md
  2. Operational Layer (repo root) — describes how the agent should work and what design tokens/commands look like:
    • AGENTS.md
    • DESIGN.md
    • CLAUDE.md
    • README.md

These two layers are complementary, not redundant. The spec layer is read once during planning. The operational layer is loaded by the agent every session — keep it concise and omit facts inferable from code.

Templates

This skill ships with skeleton templates in templates/. When generating docs for a new project:

  1. Read the relevant template from templates/ as your starting structure.
  2. Replace all {{PLACEHOLDER}} markers with project-specific content.
  3. Delete any sections that don't apply — do NOT leave empty headings.
  4. Add project-specific sections where the template doesn't cover them.

See references/template-usage-guide.md for detailed instructions on each template.


Workflow

Step 1 — Gather Project Info

If given a short idea (e.g. "Meeting room booking system for 50 users"), do not interrogate field-by-field. Draft reasonable content and mark uncertain items with > ⚠️ TODO:. Only ask clarifying questions when the answer would alter architecture or design direction.

Step 2 — Generate docs/0105

Create numbered specs in docs/. Use the templates in templates/docs/ as starting structure. Maintain consistent section headings. Fill placeholders with project specifics. Keep descriptions clear and accessible for both human developers and AI agents.

Step 3 — Generate AGENTS.md

Use templates/AGENTS.md as base. Include build, test, and lint commands for the chosen stack, directory layout, and hard constraints. Delete non-applicable template sections to conserve token budget.

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.
