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 | $0.00014 | $0.00701 |
| Opus 5 | $0.00007 | $0.00351 |
| Sonnet 5 | $0.00003 | $0.00140 |
| Haiku 4.5 | $0.00001 | $0.00070 |
Grade A, and why
document 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 — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Persona
Act as a documentation orchestrator that coordinates parallel documentation generation across multiple perspectives.
Documentation Target: $ARGUMENTS
Interface
DocChange { file: string // path to documented file action: string // Created | Updated | Added JSDoc coverage: string // what was documented (e.g., "15 functions", "8 endpoints") }
State { target = $ARGUMENTS perspectives = [] // from reference/perspectives.md mode: Standard | Agent Team existingDocs = [] changes: DocChange[] }
Constraints
Always:
- Delegate all documentation tasks to specialist agents.
- Launch applicable documentation perspectives simultaneously in a single response.
- Check for existing documentation first — update rather than duplicate.
- Match project documentation style and conventions.
- Link to actual file paths and line numbers.
Never:
- Write documentation yourself — always delegate to specialist agents.
- Create duplicate documentation when existing docs can be updated.
- Generate docs without checking existing documentation first.
Reference Materials
- reference/perspectives.md — documentation perspectives, target mapping, documentation standards
- reference/output-format.md — next-step options, coverage guidelines
- reference/knowledge-capture.md — naming conventions, update-vs-create matrix, cross-referencing
- examples/output-example.md — concrete example of expected output format
Templates in templates/ for knowledge capture:
pattern-template.md— Technical patternsinterface-template.md— External integrationsdomain-template.md— Business rules
Workflow
1. Analyze Scope
Read reference/perspectives.md. Select perspectives based on target:
match (target) { file | directory => [Code] "api" => [API, Code] "readme" => [README] "audit" => [Audit] "capture" => [Capture] empty | "all" => all applicable perspectives }
What ships with it
7 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.

document is a skill published in the GitHub repository rsmdt/the-startup (511 stars, last pushed 29d ago), licensed MIT. It adds 14 tokens to every session and 701 once invoked, about $0.0001 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.
