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.

SkillSpector: 17 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Prompt Injection · line 326 Hidden instructions were detected in comments or invisible text. These could contain malicious directives. Manual review is recommended.Fix: Audit all comments and invisible characters. Remove any instructions that direct the agent to perform unauthorized actions. Use plain, reviewable content.
- high Excessive Agency · line 412 Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.
- high Supply Chain · line 426 Remote code is downloaded and executed. This bypasses code review and could introduce malicious code.Fix: Avoid downloading and executing remote scripts. Use trusted packages from PyPI/npm. If remote fetch is required, verify checksums and use HTTPS.

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 | $0.00064 | $0.07416 |
| Opus 5 | $0.00032 | $0.03708 |
| Sonnet 5 | $0.00013 | $0.01483 |
| Haiku 4.5 | $0.00006 | $0.00742 |
Grade A, and why
agent-architecture-planner 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 13d 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.

The opening of the file, as written. The whole thing — 766 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent Architecture Planner
Design autonomous agents using the "Shell Orchestrates, Claude Thinks" pattern. This skill takes a workflow description, selects the right architecture pattern, and produces a complete agent package: shell wrapper, system prompt, config, scheduling setup, and cost estimate.
The core principle: the shell handles everything deterministic (API calls, file I/O, scheduling, budget tracking), and Claude handles everything that requires judgment (scoring, filtering, writing, categorizing). This separation makes agents cheaper, more reliable, and easier to debug.
Tools Used
| Tool | Purpose |
|---|---|
Read |
Check for existing agent docs, load reference files |
Write |
Output all agent architecture files |
Bash |
Make shell scripts executable, verify directory structure |
Glob |
Check for existing agents to avoid naming conflicts |
Methodology
Follow these steps in order. Do not skip steps. Do not produce output files before completing the discovery interview and confirming the architecture with the user.
Step 1 — Workflow Discovery (Interactive)
Present these questions to the user all at once in a numbered list. Tell the user they can answer inline or paste a block of text.
Ask exactly these questions:
I need to understand the workflow before designing the agent. Answer these 6 questions — be as specific as possible.
1. What task do you want to automate? (Describe the manual workflow as you do it today, step by step.)
2. How often should it run? (Every hour, daily, every 2 days, weekly, on-demand only?)
3. What data sources does it need? (APIs, websites to scrape, databases, local files, RSS feeds?)
4. What should it produce? (Report files, database entries, API calls, Slack messages, emails, CSV exports?)
5. What decisions does it need to make? (Scoring relevance, filtering noise, writing content, categorizing items, choosing actions?)
6. What's your budget constraint? (Max cost per run in dollars, or monthly ceiling. Include both API/data costs and LLM costs if you know them.)
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.
- 13d ago First seen · 766 lines · 64 tokens per session scan A b0e34be464c6
agent-architecture-planner is a skill published in the GitHub repository majiayu000/claude-skill-registry (604 stars, last pushed yesterday), licensed MIT. It adds 64 tokens to every session and 7,416 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
