Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00036 | $0.03742 |
| Opus 5 | $0.00018 | $0.01871 |
| Sonnet 5 | $0.00007 | $0.00748 |
| Haiku 4.5 | $0.00004 | $0.00374 |
Grade A, and why
pm-domain-analysis 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 12d 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 — 427 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PM - Domain Analysis & Legal Requirements
Agent mode (--agent)
Supports --agent: runs autonomously in a subagent, drafts the artifact from existing inputs, and returns a short summary + coverage note.
- No flag → interactive (default); if inputs are heavy, offer agent mode.
--agent→ obey. First check inputs are complete. Anything missing: do NOT invent it - mark[ASSUMED - what/why]in the output and summary. Never hallucinate to fill a gap.
What this skill does
Takes raw research input (Perplexity deep research on domain, regulatory landscape, licensing, industry norms) and produces a structured Domain Analysis Report + Legal & Regulatory Requirements document.
This is a "bring your data" skill - Claude structures and formalizes. Legal analysis should be validated by a legal professional before acting on it.
Dependencies
Recommended before running:
pm-project-charter- target markets and regulatory context are defined there
Produces artifacts used by:
pm-problem-validation- domain analysis is Track B inputpm-business-rules-library- domain constraints shape business rules and decision modelspm-privacy-requirements- legal requirements feed directly into privacy planning
Step 0: Current state check
Check for existing artifacts:
- Domain Analysis Report
- Legal & Regulatory Requirements
Also check: does a Project Charter exist? Cross-reference target markets and any regulatory constraints noted there.
Look for: regulatory requirements marked TBD, missing legal professional validation note, showstoppers not explicitly stated, EU AI Act assessment missing for AI products.
Interaction: Group related questions (2-4 per round) and confirm before moving on. For any A/B/C/D choice, use the AskUserQuestion tool with one option marked (Recommended) - never print options as plain text. Keep open-ended questions free-text (don't fake options). If the user is unsure, propose 3-4 concrete options plus "Other". Surface an assumption the moment you make one; never fabricate to fill a gap. (Full standard: CLAUDE.md.)
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.

pm-domain-analysis is a skill published in the GitHub repository ljucask/pureinn-product-development (2 stars, last pushed 2d ago), licensed MIT. It adds 36 tokens to every session and 3,742 once invoked, about $0.0002 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 2026-08-31.
