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.

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 | $0.00030 | $0.04806 |
| Opus 5.5 | $0.00012 | $0.01922 |
| Sonnet 5.5 | $0.00006 | $0.00961 |
| Haiku 4.5 | $0.00003 | $0.00481 |
Grade A, and why
workflow-principles 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 — 397 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Development Principles Generator
You are a software architecture expert that generates tailored development principles for CLAUDE.md files based on a project's actual structure, technology stack, and architectural patterns.
Instructions
CRITICAL: This command MUST NOT accept any arguments. If the user provided any text or paths after this command (e.g., /workflow-principles ./src), you MUST COMPLETELY IGNORE them. You MUST ONLY gather requirements through the interactive AskUserQuestion tool and project analysis as specified below.
BEFORE DOING ANYTHING ELSE: Perform automated project discovery, then use the AskUserQuestion tool to interactively configure the principles. DO NOT skip these steps.
Phase 1: Automated Project Discovery
Before asking any questions, silently analyze the project to understand its structure. This information will be used to tailor questions and generate context-aware principles.
1.1 Project Structure Detection
Use Glob and Read to detect:
Monorepo detection:
- Check for workspace configuration:
package.jsonwithworkspacesfieldpnpm-workspace.yamllerna.jsonnx.jsonturbo.jsonrush.json- Multiple
.csprojfiles with a.slnfile Cargo.tomlwith[workspace]sectiongo.workfile
- If monorepo detected, map the workspace packages:
- Read the workspace config to get package paths
- Glob for
packages/*/package.json,apps/*/package.json,libs/*/package.json, or equivalent - Identify shared/common packages (commonly named:
shared,common,core,utils,types,contracts,lib) - Map dependency direction between packages
Single project detection:
- Standard single-package project structure
- Note the primary source directory (
src/,app/,lib/, etc.)
1.2 Technology Stack Detection
Scan for project configuration files:
Languages:
- TypeScript:
tsconfig.json(read forstrictmode, path aliases) - JavaScript:
package.jsonwithout tsconfig - C#/.NET:
*.csproj,*.sln(read for target framework, nullable reference types) - Python:
pyproject.toml,requirements.txt,setup.py - Go:
go.mod - Rust:
Cargo.toml - Java/Kotlin:
pom.xml,build.gradle
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.

workflow-principles is a skill published in the GitHub repository charlesjones-dev/claude-code-plugins-dev (35 stars, last pushed 14d ago), licensed MIT. It adds 30 tokens to every session and 4,806 once invoked, about $0.0001 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 2026-09-06.

gwm
Manage git worktrees across any repository with the gwm Rust binary (CLI + ratatui TUI). Use when the user asks to create / list / remove / bootstrap / switch / link worktrees, run a command across worktrees (gwm exec) or reclaim build artifacts (gwm clean), materialise a PR into a worktree (gwm review), drive a…
merge-batch
Prepare and merge an owner-selected PR batch with contributor credit and exact-candidate admission. Use for a pasted PR list; combined focused validation is diagnostic, and every actual landing still requires its applicable checks and authorization.
gh-auth-isolation
Safely manage multiple GitHub identities (EMU + personal) in agent workflows.
comet-github
A routing guide for Comet-related GitHub work. It directs requests about pull requests, issues, CI failures, ideas, and fixes to the appropriate review or implementation process.
release-helper
Ensures configuration and code changes are released correctly. Use PROACTIVELY whenever you edit config.json, change any setting, or fix a configuration bug in this project, so the change reaches production.
merge-pr
Merge a pull request with status checks, squash merge, and branch cleanup. Handles worktree contexts.
