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 | $0.00133 | $0.04398 |
| Opus 5 | $0.00067 | $0.02199 |
| Sonnet 5 | $0.00027 | $0.00880 |
| Haiku 4.5 | $0.00013 | $0.00440 |
Grade A, and why
pm-mvp-scope 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 — 376 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PM - MVP Scope
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.- Review required: the artifact contains commitments - after drafting, require the user's review before finalizing; do not close decisions autonomously.
What this skill does
Phase 5 / Steps 4-5. Takes the prioritized, dependency-mapped FDD Feature List (Live Register 4, output of pm-features-list) and produces the delivery structure:
- MVP Scope Decision - what is IN (MVP), what is POST-MVP, what is CUT. Decision is per Feature - not per Feature Set. Feature Sets are grouping only and do not affect the MVP cut. MVP membership is recorded in the
phasefield, NOT a separatemvpboolean - see the next section. - Delivery Stripes - parallel development tracks (not time-boxed sprints). Each stripe is an isolated channel for a coherent domain slice (e.g., stripe-checkout, stripe-auth). Features are assigned to stripes based on domain affinity and dependencies.
- Stripe assignment - updates
stripe:field in each Feature Card frontmatter and in feature_list.md.
After user approval: update Notion Feature entries with phase and stripe assignment.
phase is the single axis for MVP membership - no separate mvp flag
The canonical Feature Card carries one field for this: phase (MVP / MVP+ / Phase 1 / … - or a project's own labels like P0 / P1). MVP membership is the phase value: IN-MVP = phase: MVP (or the project's first/P0 phase); POST-MVP = a later phase; CUT = removed / What we are NOT building. Never write a separate mvp: true/false (or roadmap_phase) field - that duplicates phase on the same axis and the two drift apart. One field, one source of truth.
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-mvp-scope is a skill published in the GitHub repository ljucask/pureinn-product-development (2 stars, last pushed 2d ago), licensed MIT. It adds 133 tokens to every session and 4,398 once invoked, about $0.0007 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.
