draft-spec

draft-spec is a skill for Claude Code, Codex from firatcand/forge. It costs 35 tokens per session (339 once invoked), scanned A, original, MIT.

A procedure for turning a product requirements document into a technical specification covering the software stack, data, user flows, security, environment settings, performance, and monitoring.

In plain words
What is it for?
Use it when spec/PRD.md is ready and you need to create spec/SPEC.md, including database relationships, integrations, authentication, authorization, and performance targets.
Why use it?
It gives implementation work a shared technical design and makes important decisions and edge cases explicit before coding starts.

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

draft-spec 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 1mo 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

/draft-spec

Preconditions

spec/PRD.md must exist (Gate 2 must have passed).

Orchestration

  1. Read spec/PRD.md
  2. Read ~/.claude/CLAUDE.md for any stack_preferences block
  3. Check if user has a software-architect skill available — if yes, invoke it with PRD + stack preferences
  4. If not, use templates/SPEC.template.md and guide Claude through filling sections
  5. Invoke security-auditor subagent in advisory mode for the chosen stack — get security model recommendations
  6. Write to spec/SPEC.md

Required SPEC sections

  • Stack (runtime, frontend, backend, db, hosting, auth)
  • Data model (tables, relationships, indexes)
  • Key flows (numbered steps with edge cases)
  • Integration points (external services)
  • Security model (authN, authZ, sensitive data handling)
  • Environment variables (12-Factor compliant — names + descriptions)
  • Performance targets (p95 metrics)
  • Observability (logs, metrics, errors)

Stack choice ceremony

If SPEC implies a tech stack not yet committed, invoke Confusion Protocol:

  • List 2-3 viable options
  • Show concrete trade-offs
  • Stop and ask user to pick before writing

Output

Print confirmation + Gate 3 instructions.

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.
