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 | $0.00041 | $0.01760 |
| Opus 5.5 | $0.00016 | $0.00704 |
| Sonnet 5.5 | $0.00008 | $0.00352 |
| Haiku 4.5 | $0.00004 | $0.00176 |
Grade B, and why
blueprint-prp-create scanned grade B 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 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

/blueprint:prp-create
Create a comprehensive PRP (Product Requirement Prompt) - a self-contained packet with all context an AI agent needs to deliver production code on first attempt.
What is a PRP? PRD + Curated Codebase Intelligence + Implementation Blueprint + Validation Gates = everything needed for reliable implementation.
Usage: /blueprint:prp-create [feature-name]
Prerequisites:
- Blueprint Development initialized (
docs/blueprint/exists) - Clear understanding of the feature to implement
When to Use This Skill
| Use this skill when... | Use alternative when... |
|---|---|
| Creating new feature implementation packet | Executing an existing PRP (use /blueprint:prp-execute) |
| Want comprehensive research and documentation | Quick prototyping without formal requirements |
| Planning for AI agent or subagent execution | Solo developer implementing without research |
| Need to document implementation approach | Implementing based on existing codebase patterns |
Context
- Blueprint initialized: !
find . -path '*/docs/blueprint/*' -maxdepth 3 -name 'manifest.json' -type f - Last PRP ID: !
find . -path '*/docs/blueprint/manifest.json' -maxdepth 3 -exec jq -r '.id_registry.last_prp // 0' {} + - Curated rules available: !
find . -maxdepth 3 -path '*/.claude/rules/*' -type f -name "*.md" - Existing PRDs: !
find . -path '*/docs/prds/*' -name "*.md" -type f
Parameters
Parse $ARGUMENTS:
feature-name(required): Kebab-case name for PRP (e.g.,auth-oauth2,api-rate-limiting)- Used for filename and document ID generation
Execution
Execute the complete PRP creation workflow:
Step 1: Verify prerequisites and understand requirements
- If Blueprint not initialized → Error: "Run
/blueprint:initfirst" - Ask user to describe the feature: "What feature needs to be implemented?"
- Capture: Goal, why it matters, success criteria
- Ask if this implements an existing PRD: "Does this implement an existing PRD or is it standalone?"
- If PRD chosen → Store PRD ID for linking
- Determine feature type (API endpoint, database, UI, integration, etc.)
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

blueprint-prp-create is a skill published in the GitHub repository laurigates/claude-plugins (60 stars, last pushed yesterday), licensed MIT. It adds 41 tokens to every session and 1,760 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
Other skills, from other repositories
extract-ssot
Deduplicate repeated markdown (rule files, skill bodies, ADRs, docs) into one named source of truth and migrate every call site to cite it by exact heading. Use when the same prose, literal, or concept recurs across files: 'DRY this prose', 'extract a shared rule', 'single source of truth for X', a value-bump diff…
feature-branch-pr-writing
Use this skill when the user asks to write, draft, create, or improve a PR description for a Shopware core repository PR — AND that PR targets a non-trunk feature branch (not trunk itself). Trigger phrases like "write a PR description", "draft the PR", "what should I put in the PR body". The skill detects the target…
repo-activity
Scan all git repositories under /repos and report recent activity — last commit age, branch, uncommitted changes — in age-bucketed tables. Use when the user asks for a repo activity overview, "what have I been working on", portfolio status, or which repos are active/dormant.
use-class-for-state
For complex state: encapsulate multiple interacting variables, stateful algorithms, backtracking search state.
display-grid-state
For 2D debugging: visualize grid/board state, show puzzle progress, make algorithm behavior visible.
renovate-triage
Use when triaging open Renovate PRs across your own repos into merge / close / defer. Activates on "renovate triage", "review dep PRs", "monthly deps", or on the 1st of a month if deps are grouped monthly.
