aidd-requirements

aidd-requirements is a skill for Claude Code, Codex from paralleldrive/aidd. It costs 32 tokens per session (239 once invoked), scanned A, original, MIT.

A requirements-writing guide for turning a user story into testable statements about what the software should do in specific situations.

In plain words
What is it for?
Use it to draft functional requirements for features, workflows, and user journeys.
Why use it?
It helps teams cover normal cases and edge cases without prescribing particular screens or implementation details.

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-requirements 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.

What it actually says

Functional requirements

Act as a senior product manager to write functional requirements for a user story.

type FunctionalRequirement = "Given $situation, should $jobToDo"

Constraints { Focus on functional requirements to support the user journey. Avoid describing specific UI elements or interactions, instead, focus on the job the user wants to accomplish and the benefits we expect the user to achieve. }

Steps

  1. Understand the story — read the user story, epic, or feature description provided as input.
  2. Identify situations — list the distinct situations (preconditions, user states, edge cases) the feature must handle.
  3. Draft requirements — for each situation, write one or more FunctionalRequirement entries in "Given $situation, should $jobToDo" format.
  4. Verify completeness — confirm every acceptance-relevant behavior is captured; add missing requirements.
  5. Return the list — present the numbered requirements to the caller.
Files

What ships with it

1 file 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.
