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 | $0.00035 | $0.00972 |
| Opus 5 | $0.00017 | $0.00486 |
| Sonnet 5 | $0.00007 | $0.00194 |
| Haiku 4.5 | $0.00003 | $0.00097 |
Grade A, and why
solid-astro 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 2d 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.
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 — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Provides ready-to-copy templates for components, layouts, services, and interfaces that already follow these rules. This is a cross-cutting code-quality skill, not a feature skill — it doesn't teach Astro APIs themselves (see astro-7, astro-content, astro-i18n, astro-styling for that), only how to structure the code that uses them.
SOLID Astro — Modular Architecture
Agent Workflow (MANDATORY)
Before ANY implementation, use TeamCreate to spawn 3 agents:
- fuse-ai-pilot:explore-codebase - Analyze project structure, naming, and existing patterns
- fuse-ai-pilot:research-expert - Verify Astro 7 architecture best practices via Context7/Exa
- mcp__context7__query-docs - Check Astro component API and TypeScript integration
After implementation, run fuse-ai-pilot:sniper for validation.
Codebase Analysis (MANDATORY)
Before ANY implementation:
- Explore
src/directory to understand existing architecture - Read existing similar files to follow established naming and patterns
- Grep for similar function/component names before creating new ones
- Identify where interfaces, utilities, and shared logic live
DRY Enforcement (MANDATORY)
Before writing ANY new code:
- Grep for similar logic — function names, class patterns, component names
- Check
src/lib/for existing utilities - Check
src/components/for existing UI components - If logic appears in 2+ places → extract to
src/lib/ - If types appear in 2+ files → move to
src/interfaces/
Absolute Rules
- Files < 100 lines — split at 90
- All types in
src/interfaces/— never in component files - JSDoc mandatory on all exported functions
- No business logic in
src/pages/
What ships with it
10 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.

solid-astro is a skill published in the GitHub repository fusengine/agents (25 stars, last pushed 29d ago), licensed MIT. It adds 35 tokens to every session and 972 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 2026-08-30.
