Project Starter is a workflow plugin that equips coding agents with specialized subagents, reusable skills, commands, hooks, and output styles for software projects. It is for developers who want structured assistance with tasks such as planning, debugging, code review, security, and automation across several coding-agent platforms. Catalogue add-ons are components of its own workflow.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.01032 | $0.01032 |
| Opus 5 | $0.00516 | $0.00516 |
| Sonnet 5 | $0.00206 | $0.00206 |
| Haiku 4.5 | $0.00103 | $0.00103 |
Grade A, and why
claude-workflow-v2 CLAUDE.md scanned grade A with 1 finding 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.

Development Workflow
Making Changes
-
Before editing any file:
- Run
claude plugin validateto ensure current state is valid - Check existing patterns in similar files
- Run
-
When adding agents (
agents/*.md):- Copy structure from
agents/orchestrator.mdas template - Include "PROACTIVELY" in description for auto-triggering
- Specify tools, model (opus/sonnet/haiku), and skills
- Test trigger keywords work as expected
- Copy structure from
-
When adding skills (
skills/*/SKILL.md):- Keep under 500 lines for optimal context usage
- Include trigger keywords in description
- Make content language-agnostic where possible
-
When adding hooks (
hooks/*):- Register in
hooks/hooks.json - Use
${CLAUDE_PLUGIN_ROOT}for paths - Exit codes: 0 = allow, 2 = block with message
- Test with both success and failure cases
- Register in
-
After all changes:
- Run
claude plugin validate - Test the specific feature with Claude Code
- Run
Code Conventions
Markdown Files
- Use YAML frontmatter for metadata
- Consistent heading hierarchy (# > ## > ###)
- Code blocks with language specifiers
Python Hooks
- Use
#!/usr/bin/env python3shebang - Read input from stdin as JSON
- Handle all exceptions silently (don't block operations)
- Use subprocess.run with timeout
JSON Files
- 2-space indentation
- No trailing commas
- Validate syntax before committing

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.

claude-workflow-v2 CLAUDE.md is an instructions file published in the GitHub repository CloudAI-X/claude-workflow-v2 (1,413 stars, last pushed 11d ago), licensed MIT. It adds 1,032 tokens to every session, about $0.0052 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
