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 5.1 | $0.00066 | $0.04554 |
| Opus 5 | $0.00033 | $0.02277 |
| Sonnet 5 | $0.00013 | $0.00911 |
| Haiku 4.5 | $0.00007 | $0.00455 |
Grade A, and why
write-test-cases 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 9d 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 — 323 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Write Test Cases
You are tasked with generating manual test case specifications for a single feature by analyzing code in parallel and producing flow-based test case documents for QA teams.
Initial Setup
When this command is invoked, respond with:
I'll generate test cases for this feature. Let me discover the relevant code and analyze it.
Then proceed to Step 1.
Steps
Step 1: Determine Feature Scope
Parse the user's input to determine the feature under test. Handle these input forms:
-
_meta.md path (e.g.,
.rpiv/test-cases/users/_meta.md):- Read the file. Extract
featurefrom frontmatter. Mark as has _meta.md.
- Read the file. Extract
-
Feature folder or slug (e.g.,
.rpiv/test-cases/order-management/ororder-management):- Check if
.rpiv/test-cases/{input}/_meta.mdexists - If yes: read it, extract
feature, mark as has _meta.md - If no: treat as feature name
- Check if
-
Source code path (e.g.,
src/orders/orsrc/api/controllers/OrdersController.ts):- Use the path directly as the starting point for analysis
-
Feature name with optional instructions (e.g.,
Order Management focus on refund edge cases):- Parse as
{feature identifier} [additional instructions] - Check if
.rpiv/test-cases/{slugified-name}/_meta.mdexists — if yes, read it and mark as has _meta.md - Store additional instructions as supplemental context for agent prompts and checkpoint
- Parse as
-
No arguments provided:
I'll help you generate test cases. Please provide either: 1. A feature name: `/skill:write-test-cases Order Management` 2. A component path: `/skill:write-test-cases src/orders/` 3. A feature slug: `/skill:write-test-cases order-management` 4. A _meta.md path: `/skill:write-test-cases .rpiv/test-cases/orders/_meta.md` Add instructions after the feature: `/skill:write-test-cases Order Management focus on refund edge cases`Then wait for input.
Warm-Start from _meta.md
When _meta.md is available, read it FULLY and extract:
- Identity:
feature,module,portal,slugfrom frontmatter - Routes: from
## Routessection — route paths and component names - Endpoints: from
## Endpointssection — HTTP methods and paths - Scope decisions: from
## Scope Decisionssection — in/out of scope items - Domain context: from
## Domain Contextsection — business rules and intentional behaviors - Checkpoint history: from
## Checkpoint Historysection — prior Q&A pairs

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.

write-test-cases is a skill published in the GitHub repository juicesharp/rpiv-pi (11 stars, last pushed 4mo ago), licensed MIT. It adds 66 tokens to every session and 4,554 once invoked, about $0.0003 per session on Opus 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 2026-08-30.
