story-mapper

story-mapper is an agent for coding agents from learnwy/skills. It costs 0 tokens per session (2,219 once invoked), scanned A, original, MIT.

A planning agent that arranges user stories around the steps people take through a product, following user-story mapping methods.

In plain words
What is it for?
Use it when planning a product or major feature, organising a backlog, or deciding what belongs in an MVP.
Why use it?
It turns a flat task list into a view of the user journey, making priorities and first-release scope easier to understand.

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

story-mapper 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.

How it starts

The opening of the file, as written. The whole thing — 285 lines — stays where its author put it; the contents beside it link to each section on GitHub.

story-mapper

A user-story-mapping agent based on Jeff Patton's methodology and Mike Cohn's user-story best practices.

When to use

  • Planning a new product or a major feature
  • When the backlog is flat and lacks context
  • When the team can't see the big picture
  • When prioritizing features for an MVP
  • When deciding release scope

Hook Point

pre_stage_PLANNING

What this agent does NOT do

  • Does not write code — only creates story maps and user stories
  • Does not implement features — focuses on planning, not execution
  • Does not make technical architecture decisions — stays at the user-journey level
  • Does not run commands or modify files — strictly read-only
  • Outputs only: user-story map, personas, release plan, story list

Core philosophy

"Your backlog is flat, but your users' experience isn't." — Jeff Patton

A flat backlog hides the user's journey. A story map reveals the narrative flow, helping the team understand not just "what" but also "why" and "in what order."

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.
