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 5.1 | $0.00067 | $0.01810 |
| Opus 5 | $0.00034 | $0.00905 |
| Sonnet 5 | $0.00013 | $0.00362 |
| Haiku 4.5 | $0.00007 | $0.00181 |
Grade A, and why
skill-factory-router 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 8d 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 — 129 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill Factory Router
Select the smallest durable Skill Factory workflow for a Codex skill-management request, then return a read-only routing handoff before loading deeper instructions.
When To Use
- The user asks to create, capture, improve, audit, refactor, install, sync, list, prove, or route a Codex skill.
- The request names skill work but the correct Skill Factory lane is not already certain.
- The request depends on Tessl, Plugin Eval, validation, runtime, installation, package visibility, or session evidence and needs the correct owner lane before action.
Do not use this router to execute the downstream lane. Route plugin package lifecycle work to plugin-factory. Route system creator and installer work to the system lanes instead of copying those bodies into Skill Factory.
Example requests that should trigger this router:
- "Create a skill from this workflow and tell me which lane owns it."
- "This skill is failing package proof; route the smallest hardening workflow."
- "Should this be skill-refactor, skillify, or the system skill creator?"
Start with the smallest package boundary that can answer the routing question. Inspect the target request, target skill, and one evidence handle before expanding to broader package or runtime state.
Inputs
- User request or named target skill.
- Current authority boundary: read-only routing, approved edit, install or sync, eval execution, package publication, or review-only.
- Available evidence handle when routing depends on Tessl, Plugin Eval, validation, runtime, review, or session artifacts.
If target, lane, write authority, or validation requirement is missing, ask one plain-language question. Load references/discovery-interview.md only when that ambiguity cannot be resolved from the user request.
Outputs
Return one YAML handoff:
schema_version: 1
selected_lane: .system/skill-creator|skillify|skill-factory-router|skill-refactor|.system/skill-installer
mode: create|capture|harden|analyze|install
rationale: <one sentence tied to the request shape>
next_step: <specific skill or system lane to load next>
first_principles_check:
required: true|false
result: skill|docs|script|hook|validator|rule|answer|not_checked
blocked_by: null
What ships with it
6 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.

skill-factory-router is a skill published in the GitHub repository jscraik/Agent-Skills (8 stars, last pushed 10d ago), licensed Apache-2.0. It adds 67 tokens to every session and 1,810 once invoked, about $0.0003 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 2026-09-03.
