analysis-skill-router

analysis-skill-router is a skill for Claude Code, Codex from event4u-app/agent-config. It costs 47 tokens per session (966 once invoked), scanned A, original, MIT.

A chooser for selecting the right code-analysis skill when a request could follow several investigation paths. It considers the project scope, framework, and symptoms.

In plain words
What is it for?
It helps choose between project reviews, architecture checks, multi-layer debugging, framework investigations, root-cause analysis, and performance or security reviews.
Why use it?
It removes the guesswork when someone asks for a broad analysis or when several specialist analysis skills might fit. It does not perform the analysis itself.

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

analysis-skill-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 — 109 lines — stays where its author put it; the contents beside it link to each section on GitHub.

analysis-skill-router

A chooser, not a worker. It answers exactly one question — which skill — and then gets out of the way. How to actually carry out the work belongs to whichever skill this picks; a chooser that also explains the work reads like its own fallback target, which is the defect this file was cut back from.

When to use

Use this skill when:

  • A request may need deep analysis
  • It is unclear which analysis skill should be used
  • Multiple analysis skills could plausibly apply
  • The stack/framework is known but the correct analysis path is unclear
  • analysis-autonomous-mode needs a routing decision

Do NOT use when:

  • The correct specialist skill is already obvious
  • The task is not an analysis task
  • The task is normal implementation work without investigation needs

Procedure

1. Classify the scope

Pick one: full project · architecture review · broad multi-layer debugging · framework-specific deep dive · narrow root cause · performance/security specialist · simple local issue.

Broad scope requires a reason. At least one must hold, or the answer is a narrow specialist: the user asked for breadth · the system is unknown · the issue spans layers · architecture must be reconstructed · the cause is non-local.

2. Detect the framework

Laravel · Symfony · Zend/Laminas · Node/Express · React · Next.js · unknown or mixed.

3. Read the decision table

Signal Route to
Full audit, or unclear stack universal-project-analysis
Unknown system, discovery-focused project-analysis-core
Concrete problem, several plausible causes project-analysis-hypothesis-driven
Bug-focused, not full-project bug-analyzer

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.
