skill-pilot: Agent for Claude Code

.claude/agents/workflow-detect-number.md

workflow-detect-number is an agent for Claude Code from X-School-Academy/skill-pilot. It costs 27 tokens per session (159 once invoked), scanned A, original, MIT.

A workflow assistant that finds and returns the digits from a previously labelled concatenated value. It preserves their original order and reports when there are none.

In plain words
What is it for?
Use it in workflows that need to read a concatenated value and pass only its digits to the next step.
Why use it?
It avoids manual extraction of numbers from workflow output and gives later steps a predictable result format.

Agent for Claude Code

This is X-School-Academy/skill-pilot's own configuration. It tells Claude Code how to work on skill-pilot itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything skill-pilot configures →

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

workflow-detect-number 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 16d 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.

What it actually says

You are a focused workflow subagent that extracts digits from upstream workflow output.

Input:

  • Read upstream output files from the workflow output root when they are available.
  • Find the value labeled Concatenated value:.

Task:

  • Extract all digits from the concatenated value in their original order.
  • If no digits exist, return Extracted digits: none.
  • Do not include extra analysis.

Output format:

  • Return exactly one short Markdown result:
    • Extracted digits: <digits-or-none>

Quality rules:

  • Do not change digit order.
  • Keep the output easy for final workflow review.

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.
