aidd-pm:05:spec

A tool that turns a free-form request into a written project specification. The specification records the agreed target for later planning and implementation.

In plain words
What is it for?
Use it to draft a specification from a request or product requirements document, or revise an existing specification after review findings.
Why use it?
Unstructured requests can leave requirements open to interpretation or change during development. A checked specification gives the team a shared reference.

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

aidd-pm:05: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 yesterday.

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 — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Skill: spec

Produces a complete spec from a free-form human request. The spec is the contract between human intent and downstream agents (planner, implementer, reviewer). It is immutable once validated.

When to use

  • A human types /spec <request> to draft a spec
  • The aidd-dev:00:sdlc orchestrator invokes this skill at Phase 1 of a run
  • An existing spec failed reviewer validation and needs refinement based on findings

When NOT to use

  • A validated spec already exists → use it directly, no need to regenerate
  • The user only wants a single requirement clarified → use aidd-pm:04:clarity
  • The user wants a full PRD with stakeholders, OKRs, and rollout plan → use aidd-pm:03:prd (more granular than a spec)

Inputs

At least one of request, prd_path, or existing_spec is required.

request: <free-form human description, optional>
prd_path: <path to an existing PRD file, optional — extracted into a spec>
existing_spec: <optional path — for refinement runs>
findings: <optional — reviewer findings to address>
working_dir: <where the spec.md will be written>

Priority when multiple are provided:

  1. existing_spec + findings → refinement run (rewrite to address findings)
  2. prd_path → extract scope, target, constraints, non-goals, done-when from the PRD into a normalized spec
  3. request → generate from scratch using the template

Outputs

spec_path: <path to the generated spec.md>
status: draft | refined
notes: <ambiguities, assumptions made, questions for the human>

Behavior

  1. Refinement (existing_spec + findings): load both, address each finding, rewrite the spec.
  2. PRD extraction (prd_path): parse the PRD, extract target / hard constraints / non-goals / done-when into the normalized spec structure. Fields the PRD doesn't cover are marked TBD: <precise question>. Implementation details from the PRD (libraries, patterns, file layout) are dropped — they belong to the plan.
  3. From scratch (request only): produce a draft spec from the request using assets/spec-template.md as the structure.
  4. The spec must contain every required section listed in assets/spec-validator.yml. When information is missing, mark it TBD: <precise question> rather than guess. The reviewer will flag it and the human can answer in the next iteration.
  5. Write the spec to working_dir/spec.md.
  6. Return the path and status.

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

aidd-pm:05:spec is a skill published in the GitHub repository ai-driven-dev/framework (445 stars, last pushed 2d ago), licensed MIT. It adds 61 tokens to every session and 859 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
