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.

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 | $0.00028 | $0.00979 |
| Opus 5.5 | $0.00011 | $0.00392 |
| Sonnet 5.5 | $0.00006 | $0.00196 |
| Haiku 4.5 | $0.00003 | $0.00098 |
Grade A, and why
astro-content 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 1mo 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 — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Also covers MDX authoring with Remark/Rehype plugins and the astro sync workflow for generating collection types. Does not cover form submission via Astro Actions (astro-actions) or SEO metadata generation from content (astro-seo) — those are handled by their own skills.
Astro Content Layer Expert
Type-safe content management with loaders, Zod schemas, and the unified Content Layer API.
Agent Workflow (MANDATORY)
Before ANY implementation, spawn 3 agents in parallel, one Agent call each with a name:
- fuse-ai-pilot:explore-codebase - Check existing collections, loaders, and content structure
- fuse-ai-pilot:research-expert - Verify latest Content Layer docs via Context7/Exa
- mcp__context7__query-docs - Get loader and schema examples
After implementation, run fuse-ai-pilot:sniper for validation.
Overview
When to Use
- Managing blog posts, docs, or product descriptions in Markdown/MDX
- Fetching content from a CMS, API, or database with type safety
- Needing TypeScript autocomplete for frontmatter fields
- Migrating from Astro 4 legacy content collections
Why Content Layer API
| Feature | Benefit |
|---|---|
src/content.config.ts |
Single config file at project root |
| Built-in loaders | glob() and file() for local files |
| Custom loaders | Fetch from any external source |
| Zod 4 schemas | Full TypeScript type safety |
astro sync |
Generates types from collections |
Core Concepts
Config File Location
The config file moved from src/content/config.ts to src/content.config.ts in Astro 5+.
What ships with it
8 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.

astro-content is a skill published in the GitHub repository fusengine/agents (32 stars, last pushed 5d ago), licensed MIT. It adds 28 tokens to every session and 979 once invoked, about $0.0001 per session on Opus 5.5. 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.
Other skills, from other repositories
radin-record
Log bugs, follow-ups, ideas or feedback raised this session as backlog entries that outlive the conversation. Use for /radin-record or any ask to save something for later, even a vague one ("add the findings"): scan the whole session.
radin-do
Record one ad-hoc prompt as a backlog entry, then execute just that task. Use for /radin-do .
radin-stats
Show the stats/gain output of every companion tool that ships one, side by side.
radin-batch
Work backlog tasks via sub-agents, prioritized, one commit each; plans first the entries radin-record flagged as needing a plan. Use for "work through my backlog", or name an epic or task to run only those.
designing-interfaces
Creates a design system for software with a UI. Use when a project has a user interface and architecture is confirmed — whether creating from scratch or extracting patterns from existing code.
orchestrating-software-dev
Runs software development projects from idea to completion. Use when starting a software project, adding a feature, fixing a bug, or resuming an in-progress build.
