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.
npx agentmods add rules/marcoporcellato/matryca-plumber/08-github-workflow-standardsgit clone --depth 1 https://github.com/MarcoPorcellato/matryca-plumberWhat 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 | $0.00021 | $0.01428 |
| Opus 5 | $0.00010 | $0.00714 |
| Sonnet 5 | $0.00004 | $0.00286 |
| Haiku 4.5 | $0.00002 | $0.00143 |
Grade A, and why
08-github-workflow-standards 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 2d 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 — 164 lines — stays where its author put it; the contents beside it link to each section on GitHub.
GitHub Workflow Standards (Matryca Plumber)
When creating, updating, or closing GitHub issues, pull requests, milestones, or releases, follow these official GitHub best practices so the repository maintains authoritative project management.
Rule routing: Complements 05-release-preparation.mdc (semver releases), 06-auto-changelog.mdc (user-visible bullets), and the user rule for gh pr create.
Issue taxonomy
Title format
Use a category prefix + concise description + optional audit marker:
[Security] Path traversal on read in link verification [v1.9.x Audit #01]
[Bug] Hub pages written without OCC or page_rmw_lock
[Performance] AST cache full-reload on delete or parser failure
[Tech Debt] Centralize _env_bool / _env_int (8+ duplicates)
- Prefix must match the primary label category.
- Audit-track issues include
[v1.9.x Audit #NN]for idempotent bulk scripts.
Body structure (mandatory sections)
Every substantive issue body MUST use these headers (in order):
## Problem Description
## Proposed Architectural Solution
## Estimated Impact
## Files Involved
Add metadata footer when from audit or epic:
---
**Audit metadata** / **Epic link**
_Closes when merged with tests green (`make check`) and CHANGELOG updated._
Labels (semantic, lowercase)
| Label | When to use |
|---|---|
security |
Sandbox, auth, secret handling, SSRF |
bug |
Incorrect behavior, race, data loss |
performance |
I/O, memory, latency |
tech-debt |
Refactor, DRY, typing, module split |
v1.9.x |
Pre-v2.0 perfection track |
v2.0 |
Shadow DB / Safe-Sync epic |
v2-prep |
Phase 0–1: prerequisites, GraphRepository ports |
v2-alpha |
Phase 2–3: shadow sync, read routing flag |
v2-memory |
Biological memory layer |
v2-safesync |
Logseq DB Safe-Sync write bridge |
audit-2026 |
Bulk-created from perfection audit |
Create missing labels via gh label create before assigning. Use scripts/github_audit_tracker.sh as the canonical bulk importer.
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.

08-github-workflow-standards is a cursor rule published in the GitHub repository MarcoPorcellato/matryca-plumber (96 stars, last pushed 3d ago), licensed Apache-2.0. It adds 21 tokens to every session and 1,428 once invoked, about $0.0001 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.
