pm-solutions

A method for developing several possible answers to one product opportunity. It uses engineering, design, and business viewpoints, then compares the resulting ideas and their assumptions.

In plain words
What is it for?
Use it to brainstorm and compare product solutions, including their expected impact, effort, biggest uncertainty, and an initial test.
Why use it?
It prevents the team from settling on the first idea and makes the risks and cheapest ways to test each option explicit.

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 C, and why

pm-solutions scanned grade C with 2 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 443 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Multi-host portability rules. When invoking AskUserQuestion:

  1. The header field MUST be a short noun phrase (≤ 12 characters). Mistral Vibe rejects longer headers with string_too_long. Pick from: Start, Target, Scope, Audience, Methodology, Feature, Question, Confirm, Choose.
  2. The options list MUST have at least 2 items. Vibe rejects empty/single-option calls. For free-text input, always provide ≥ 2 framing options (e.g. Yes, here's the input / Skip) — never call ask_user_question with options: [].

What this skill does

/pm-solutions <opportunity-slug> is the Solutions node of the Opportunity Solution Tree (Outcome → Opportunity → Solution → Assumption). nanopm already produces Outcomes (objectives) and Opportunities (the DB), but nothing bridged an opportunity to a compared set of candidate solutions — so the founder picked the first idea in his head and jumped straight to /pm-prd. This skill fills that gap: it convenes a panel of three fixed expert lenses (Eng / Design / Business), makes them propose competing solutions in parallel, then converges them into a comparison the founder can weigh.

The shape is the same recipe each run, built on the three wiki primitives — query → reasoning → ingest (no bespoke read logic), with lint keeping it honest after the fact:

  • RESOLVE — resolve the opportunity slug to one file (or list candidates and stop).
  • QUERY (read primitive) — one nanopm_query_prompt subagent reads the wiki and returns a cited, lens-relevant grounding for the panel (the persona's JTBD, the objectives / strategy / bet, the product surface + structural constraints) — the same query op every other skill uses, instead of leaning on the preamble briefs alone.
  • DIVERGE (reasoning primitive) — three lens-subagents (Eng / Design / Business) dispatched concurrently in one turn, each grounded in the opportunity file + the cited QUERY digest.
  • CONVERGE — one pass that dedups overlapping proposals and emits ≥3 solutions, each with the full field set; the converged comparison table is canonical, but every row keeps its lens tag and a one-line dissent note — the room stays visible.
  • WRITE — one wiki/entities/solutions/<slug>.md per solution via the ingest apply primitive, regenerate INDEX.md, append a bidirectional pointer block to the parent opportunity page.
  • CHOOSE — present the comparison; the founder shortlists, then marks one chosen. The agent never auto-chooses.

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-solutions is a skill published in the GitHub repository nmrtn/nanopm (48 stars, last pushed 1mo ago), licensed MIT. It adds 119 tokens to every session and 6,460 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
