ai-feature-prd

ai-feature-prd is a cursor rule for Cursor from mohitagw15856/pm-claude-skills. It costs 95 tokens per session (1,032 once invoked), scanned A, original, MIT.

A product requirements document for a feature that uses an AI model to assist, summarise, generate, classify, or answer. It adds planning for uncertain outputs, evaluation, safeguards, and failures.

In plain words
What is it for?
Use it to plan an AI assistant, summariser, generator, classifier, or other model-based product feature from the user problem through launch requirements.
Why use it?
Normal feature plans often assume predictable results, while AI can be wrong; this document makes quality expectations, privacy, and failure handling explicit.

About the project

PM Skills is a collection of plain-Markdown instructions that teach AI assistants structured methods for handling professional, personal, and life-admin tasks. People use it with Claude, ChatGPT, Gemini, Cursor, Codex, and other supported agents for work such as writing product requirements, reviewing documents, or planning difficult situations.

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

ai-feature-prd 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 8d 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.

AI Feature PRD Skill

AI features break the normal PRD because the system is probabilistic: it will be wrong sometimes, and the product must be designed around that, not in denial of it. This skill extends a standard PRD with the AI-specific sections that decide whether the feature is trustworthy — the UX of uncertainty, the eval bar, guardrails, and what happens when the model is wrong.

Required Inputs

Ask for these only if they aren't already provided:

  • The user problem and why an AI/probabilistic approach fits it (vs. deterministic rules).
  • What "good" looks like to the user, and the cost of a wrong answer (low-stakes vs. high-stakes).
  • Inputs available — context/data the model can use; privacy constraints.
  • Trust level needed — can the user verify the output, or must it be near-perfect?

Reads from / Writes to the Brain

If a professional-brain exists, read context.md (product, users, voice) and knowledge/strategy.md first; write the feature to entities/ and any scoping decision to decisions/, each provenance-tagged.

Output Format

AI Feature PRD: [feature]

1. Problem & why AI — the user problem, and why a model (not rules) is the right tool. If rules would do, say so.

2. Experience — the core flow, and crucially the UX of uncertainty: how confidence is shown, how the user verifies/edits, and how errors are made cheap to recover from. AI features live or die here.

3. Model approach — prompt / fine-tune / RAG / agent (link rag-design-doc or agent-spec), the model tier, and why.

4. Quality bar & evaluation — the metrics and the explicit ship threshold; reference an ai-eval-plan. State the acceptable error rate given the stakes.

5. Guardrails & safety — what the feature must never do, input/output filtering, and handling of harmful/PII/out-of-scope inputs.

6. Fallback behaviour — what happens when the model is unsure, wrong, slow, or down: graceful degradation, "I'm not sure" states, human handoff. No silent confident errors.

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.
