pm-user-stories

pm-user-stories is a skill for Claude Code from serejaris/personal-corp-os. It costs 125 tokens per session (1,752 once invoked), scanned A, original, MIT.

A planning aid that breaks a large product requirement, or Epic, into smaller User Stories: short descriptions of work from a user’s point of view. It adds Given-When-Then acceptance checks, estimates, and a map for planning Sprints, which are fixed periods of development work.

In plain words
What is it for?
Use it to prepare work for Jira, Linear, or GitHub Issues, choose story sizes, split work by team roles, and suggest which stories belong in each Sprint.
Why use it?
It turns a broad request into independent pieces that can be built and checked one at a time. INVEST checks help reveal stories that are too vague, large, or dependent on one another.

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

pm-user-stories 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.

pm-user-stories — Break an Epic into User Stories

Part of the Personal Corp framework — running a one-person business through AI agents. Decompose a large requirement or Epic into independently-deliverable User Stories. Every Story is validated against INVEST. Output is ready to paste into Jira, Linear, or GitHub Issues.

Inputs

Field Required Notes
Requirement description yes An Epic or large requirement; can paste a PRD section
Granularity no Sprint-level (1-3 days/story) or iteration-level (1-2 weeks); default Sprint
Team composition no FE+BE split / full-stack / has mobile — affects per-tier splitting
Estimation system no Fibonacci (1/2/3/5/8/13) or T-shirt (S/M/L/XL); default Fibonacci

Step 1 — Map the full requirement

Extract from the requirement:

  • Roles involved: who uses this? (end user, admin, ops, etc.)
  • Core flow: main path? branches?
  • Business rules: constraints and conditions?
  • Data entities: what data objects are involved?

Step 2 — Pick a splitting pattern

Five patterns. Pick by requirement shape; combine for hybrids.

Pattern When to use Example
By workflow step Requirement is a complete process Checkout → pick item / address / payment / confirm
By business-rule variant Same feature with multiple rule sets Discount → fixed-amount / coupon / points / combined
By CRUD operation Requirement centers on one data object Address book → create / edit / delete / set default
By role perspective Multi-role feature Order management → user view / merchant processing / ops dashboard
By complexity progression Feature has simple and full versions Search → keyword / filters / suggestions / history

Selection principle: target ≤ 1 Sprint per Story. Hybrid requirements combine patterns.

Granularity calibration:

  • Stories < 3 → likely too coarse; check for hidden sub-flows
  • Stories > 20 → likely too fine, or this is multiple Epics; split Epics first
  • Single Story estimate > 8 points → too big; split further

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.
