skill-factory-router is a skill for Codex from jscraik/Agent-Skills. It costs 40 tokens per session (1,798 once invoked), scanned A, original, Apache-2.0.

A routing guide for coding-agent skill-management requests. It selects the smallest suitable workflow for creating, improving, auditing, installing, or retiring a skill.

In plain words
What is it for?
Use it to route skill requests involving validation, evaluation, installation, runtime visibility, session evidence, or package maintenance.
Why use it?
It helps choose the correct owner process before detailed instructions are loaded or changes are made.

Token cost

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.

Security

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 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.

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 explicitly asks which lane owns a Codex skill-management request.
  • 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.

Ask one plain-language question only when missing information prevents lane selection. Read-only routing does not require edit authority or a validation command. Load references/discovery-interview.md only for unresolved routing ambiguity; do not turn a clear downstream request into an interview.

Outputs

Return one YAML handoff:

schema_version: 1
selected_lane: .system/skill-creator|skillify|skill-builder|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.

Changes

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.
