vendored-skill

vendored-skill is a skill for Claude Code, Codex from linkpranay-ai/context-engineering-protocol. It costs 0 tokens per session (4,644 once invoked), scanned A, original, Apache-2.0.

A copied reference skill for writing actor-focused user stories, which describe software needs from a user's point of view, after an approved context package has been prepared.

In plain words
What is it for?
Turning approved feature context into functional, non-functional, and supporting backlog stories, while routing constraints into requirement or sequencing notes.
Why use it?
It records a reproducible case study without pretending to be an installable skill in this repository, and it gives the writing process defined coverage checks.

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

vendored-skill 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 5d 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 — 400 lines — stays where its author put it; the contents beside it link to each section on GitHub.


name: spw-write-user-story description: Write user stories (functional, NFR, Enabler) for a feature from an approved ult-context-generate context package — actor-driven coverage, constraint routing, Enabler/Requirement-Note shaping. namespace: spw version: 0.1.0 origin: ground-up author: Pranay Mishra maintainer: Pranay Mishra adapted_from: ~ upstream_version: ~ released: 2026-06-30 tags: [developer, workflow, user-stories, requirements, actors, backlog, pilot] bundle: developer tier: act

spw-write-user-story

Status: piloting. The actor-identification pass (Step 2.5), the constraint routing table (Step 3b — Enabler stories vs. Requirement Notes vs. Sequencing Notes), and the coverage gates (Step 4 — actor coverage, NFR threshold, Requirement Note coverage, Enabler cross-reference) were validated end-to-end on a real RBAC guest-role feature, including the full Enabler/Requirement-Note backlog shaping for Jira-ready output, before this migration. This skill always runs against an approved ult-context-generate context package (also piloting, utilities bundle) — install both bundles together. Report findings (works well / doesn't / surprises) back to its maintainers so this can graduate out of pilot status or be reworked.

Writes user stories for a given feature. Checks for an approved context package first; if not found, invokes ult-context-generate before generating stories.

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.

vendored-skill is a skill published in the GitHub repository linkpranay-ai/context-engineering-protocol (8 stars, last pushed 2d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 4,644 tokens. 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.
