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 | $0.00037 | $0.02999 |
| Opus 5 | $0.00018 | $0.01499 |
| Sonnet 5 | $0.00007 | $0.00600 |
| Haiku 4.5 | $0.00004 | $0.00300 |
Grade A, and why
document-detection 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 today.
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 — 345 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Document Detection
Proactively identify when conversations should become structured documents (PRDs, ADRs, or PRPs) and guide users through the documentation workflow.
When to Use This Skill
| Use this skill when... | Use blueprint-derive-plans instead when... |
|---|---|
| Mid-conversation cues suggest a PRD/ADR/PRP should be captured | You're explicitly deriving plans (PRDs/ADRs/PRPs) from existing README/docs and git history |
| The user says "I want to build...", "users should be able to..." | Use blueprint-derive-plans instead when the cue is a tech-choice decision worth an ADR |
| The user compares trade-offs ("should we use X or Y?") | Use document-linking instead to wire IDs across already-created docs |
| Implementation scope is being discussed and warrants a PRP | Use blueprint-prp-create instead when you've already decided to author a PRP |
When This Skill Activates
This skill is loaded when conversation context suggests documentation opportunities:
- Feature requirements being discussed
- Architecture decisions being made
- Implementation planning in progress
- Technology trade-offs being evaluated
Prerequisites
Document detection requires:
- Blueprint initialized in project (
docs/blueprint/manifest.jsonexists) has_document_detection: truein manifest structuredocs/directory structure created
Check prerequisites before prompting:
# Verify blueprint is initialized with document detection enabled
jq -r '.structure.has_document_detection // false' docs/blueprint/manifest.json 2>/dev/null
Detection Patterns
PRD Indicators (Product Requirements)
Primary triggers (confidence +0.5 each):
- Feature descriptions: "I want to build...", "The system should...", "We need a feature that..."
- User stories: "As a [user], I want...", "Users should be able to..."
- Requirements enumeration: Lists of features or capabilities
- Problem/solution framing: "The problem is... the solution is..."
Confidence boosters (+0.1-0.2 each):
- Multiple features mentioned (+0.2)
- User personas identified (+0.1)
- Success criteria discussed (+0.1)
- Priority levels mentioned (P0, P1, must-have, nice-to-have) (+0.1)
- Timeline or milestones mentioned (+0.1)
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.

document-detection is a skill published in the GitHub repository laurigates/claude-plugins (57 stars, last pushed yesterday), licensed MIT. It adds 37 tokens to every session and 2,999 once invoked, about $0.0002 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 2026-09-03.
Other skills, from other repositories
plan
Produce structured implementation plans with goal, approach, test strategy, blast-radius assessment, parallelism analysis, and a user approval gate before any code is written. Persisting PLAN.md for fresh-session handoff. Use when: 'plan this', 'architect this', 'how should we implement', 'implementation plan', 'write…
extract-ssot
Deduplicate repeated markdown content, rule files, skill bodies, ADRs, docs, into a single named source of truth and migrate every call site to cite it by exact heading. Use when the same prose, literal, or concept appears (or is reworded) across files: 'DRY this prose', 'extract a shared rule', 'single source of…
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…
ci-log-interpretation
Use this skill when reading or analyzing CI logs from a Shopware GitHub Actions workflow to figure out why a build failed — phrases like "why did CI fail", "what broke the build", "check the pipeline", "interpret these logs", "debug this red build" — or whenever raw run logs, job logs, or check annotations from a…
a0-create-plugin
Create, extend, or modify Agent Zero plugins. Follows strict full-stack conventions (usr/plugins, plugin.yaml, Store Gating, AgentContext, plugin settings). Use for UI hooks, API handlers, lifecycle extensions, or plugin settings UI.
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.
