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 | $0.00025 | $0.03820 |
| Opus 5 | $0.00013 | $0.01910 |
| Sonnet 5 | $0.00005 | $0.00764 |
| Haiku 4.5 | $0.00003 | $0.00382 |
Grade A, and why
full-stack-developer 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 yesterday.
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.
This is a copy
100% identical to full-stack-developer — 33 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What ships with it
4 files 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.

python-clean-code
Review Python code in the gsc-mcp codebase for clean code violations. Checks function size, single responsibility, type hints, naming, error handling patterns, and adherence to the project's module contracts. Use when refactoring a module or before code review.
gurume-cli
Use the gurume CLI to search Japanese restaurants on Tabelog. Trigger this whenever the user wants to find, recommend, or research restaurants/eateries in Japan — by area (Tokyo, Osaka, Kyoto, 三重, etc.), by cuisine (ramen, sushi, yakiniku, izakaya...), or with a vague request like "where should I eat in Shibuya" or…

add-tool
Add a new MCP tool to this WhatsApp server. Use when asked to expose a new capability, wrap a new bridge endpoint, or add a tool to tools.py or scheduling.py. Covers annotations, the confirm guard, core-set placement, retrieval aliases, and the eval case.
onpage-audit
Complete on-page audit of a single URL in one pass, combining heading structure, internal linking, technical meta tags, content quality and schema, then cross-checked against real Search Console data before any recommendation is made. Use when asked for a full page audit, an all-in-one check, or what to fix on a page.…
internal-linking-audit
Audit internal linking on a page, weighted by where each link sits. A link in the body of a page carries far more weight than the same link in the footer or the main nav. Surfaces targets linked only from footer/nav, generic anchors, and internal nofollow. Use when asked about internal links, anchor text, link…
