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 | $0.00008 | $0.01403 |
| Opus 5 | $0.00004 | $0.00701 |
| Sonnet 5 | $0.00002 | $0.00281 |
| Haiku 4.5 | $0.00001 | $0.00140 |
Grade A, and why
Documentation 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.

How it starts
The opening of the file, as written. The whole thing — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Use this skill when you need project orientation before editing or answering architecture questions.
helper
- Import
/mod/_core/documentation/documentation.js read("path/to/file.md")reads a nested markdown doc relative todocs/url("path/to/file.md")builds the resolved/mod/...URL for a doc file
workflow
- Start with the built-in documentation index below unless you already know the exact doc path
- Use one focused
read("path/to/file.md")call instead of loading many large docs blindly - Treat
/README.mdas the public product source of truth for the project pitch, quick starts, release links, community links, and DeepWiki discovery - After orientation, walk the DOX chain from
/AGENTS.mdto the owningAGENTS.mdfile and then inspect code when needed - For visual or modal work, confirm
app/L0/_all/mod/_core/visual/AGENTS.mdbefore changing dialog shells, buttons, cards, popovers, or other shared UI primitives - For dashboard panel creation, panel manifests, or panel-navigation helpers, start with
app/modules-and-extensions.md - Keep the repo's frontend-first rule in mind while reading: backend docs explain constraints and existing contracts, not default permission to edit
server/ - If the change appears to require backend work and the user did not explicitly ask for backend edits, ask for permission and explain the security, integrity, or stability reason before changing backend files
- When you change a stable contract or workflow, update the relevant DOX
AGENTS.mdfiles, including affectedChild DOX Indexentries, and the matching docs in/mod/_core/documentation/docs/ - When you add, remove, rename, or substantially repurpose a doc file, update this skill's in-file index in the same session

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.

Documentation is a skill published in the GitHub repository agent0ai/space-agent (1,388 stars, last pushed 2mo ago), licensed MIT. It adds 8 tokens to every session and 1,403 once invoked, about $0.0000 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.
