A workflow for turning feature ideas into user stories, larger epics, product requirement plans, and sprint plans. It also updates and synchronises stories as requirements change.

Use it to create or decompose stories, generate a PRP, plan a sprint, or update the backlog after a change request.

It gives feature work a structured path from an initial idea to implementation-ready tasks and planned work.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00066	$0.02949
Opus 5.5	$0.00026	$0.01180
Sonnet 5.5	$0.00013	$0.00590
Haiku 4.5	$0.00007	$0.00295

Measured 1mo ago against content hash 7cc835b345c1, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

story 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 1mo 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 — 271 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Story Pipeline — Planning, Generation & Sprint Management

Unified workflow from feature idea to ready-to-implement stories. Replaces user-story-generator, story-validator, sprint-planner, and technical-annotator.

TDD note: Do NOT use /story tests. Use /implementation directly — it has TDD built-in and generates tests from acceptance criteria with full codebase context. /story tests is archived: it produces generic stubs that conflict with implementation-generated tests.

Usage

/story                          # Auto-detect project, suggest next action
/story create                   # Feature description -> INVEST-compliant user stories
/story create --epic            # Feature too large for stories -> create EP-XXXX epic
/story create --prd             # Feature description -> PRD (aggregated stories)
/story decompose <EP-XXXX>      # Decompose an epic into child US-XXXX stories
/story prp <story-ids>          # Generate PRP from stories (invokes /prp-generator)
/story plan                     # Sprint/milestone planning from backlog
/story update                   # Create new stories from change request
/story sync                     # Push stories/epics to GitHub issues via gh CLI

Language

Always write in English. All story/epic YAML content, GitHub issue titles and bodies, acceptance criteria, and documentation must be in English. No exceptions — do not detect or adapt to project language.

Epic vs Story — quando usare quale

Usa `--epic` quando...	Usa `create` (storia) quando...
La feature richiede >3 storie figlie	La feature si implementa in 1-2 sessioni
Stima > 8 story points	Stima ≤ 8 story points
Coinvolge nuovo modello dati + UI + notifiche	Tocca un'area già strutturata
È un deliverable di bando o milestone	È un task di refinement

What ships with it

7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

story is a skill published in the GitHub repository matteocervelli/llms (25 stars, last pushed 5mo ago), licensed MIT. It adds 66 tokens to every session and 2,949 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-09-03.

Planning Project management

story-readiness

Checks whether a story is ready to implement: clear acceptance criteria, no open questions, valid ADR and dependencies. Use when the user asks if a story, or the sprint's stories, are ready to start or build.
