Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00000 | $0.00936 |
| Opus 5 | $0.00000 | $0.00468 |
| Sonnet 5 | $0.00000 | $0.00187 |
| Haiku 4.5 | $0.00000 | $0.00094 |
Grade A, and why
feature 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 — 110 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Input Format
/feature <FEATURE_DESCRIPTION> [additional instructions]
- FEATURE_DESCRIPTION: issue URL or plain description (required)
- additional instructions (optional): constraints, focus areas, or any custom guidance
Examples:
/feature https://linear.app/team/ENG-1234
/feature ENG-1234 the SpaceshipLauncher class must inherit from BaseVehicle
Context
Create and complete a new feature or chore for this project, from branch creation to PR readiness. Input can be an issue URL or a plain description.
With issue URL: Extract ID, fetch ticket details. With description only: Create new issue in the appropriate project.
Pass any additional instructions from user input through to all subagents and apply them during implementation.
Workflow
Step 1: Setup
Pull latest base branch (usually main or master)
Create feature branch: <type>/<issue-id>-<short-description> (e.g., feature/eng-1234-add-api-endpoint)
Update the ticket: assign to "me", change status to "In Progress"
Step 2: Gather Historical Context
Spawn rpi:thoughts-analyzer with ticket reference, title, description, acceptance criteria, and any additional instructions from user input.
DO NOT proceed to Step 3 until this subagent returns. Its output is required input for Step 3.
Step 3: Research Codebase
After Step 2 completes, spawn research subagents in parallel, passing ticket info, historical context output from Step 2, and any additional instructions from user input:
rpi:codebase-pattern-finder - find similar implementations to model after
rpi:codebase-analyzer - analyze the area being modified
Wait for both subagents to complete before proceeding.
Step 4: Implementation
Follow Rails best practices, CLAUDE.md, and any additional instructions from user input.
Keep code clean, DRY, well-documented.
When modifying code: fix lurking bugs, refactor, add missing tests and regression tests.
Ensure solid RSpec coverage with well-documented business logic (viewable with --format documentation).
Review changes for completeness.
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.

feature is a command published in the GitHub repository hoblin/claude-ruby-marketplace (37 stars, last pushed 25d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 936 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 2026-08-30.

sm-buff
You usually don't run buff directly — run sm sail. sm sail drives the whole PR to green and calls buff watch / triage for you, stopping only when it needs you to act (see /sm-sail). Reach for sm buff here only for surgical work: inspecting a specific failure, or resolving a single review thread when sail has parked on…

Create architecture solution design decisions for AI agent consistency. Use when the user says ""lets create architecture"" or ""create technical architecture"" or ""create a solution design"".
create-prd
Create a PRD from scratch. Use when the user says ""lets create a product requirements document"" or ""I want to create a new PRD"".
