project-explorer

project-explorer is an agent for Claude Code from konveyor-ecosystem/playpen-pf-mig-skills. It costs 35 tokens per session (386 once invoked), scanned A, original, Apache-2.0.

A project-discovery agent that examines a codebase to identify its languages, structure, build tools, development server, tests, and lint checks. It summarizes how the project is organized and run.

In plain words
What is it for?
Use it at the beginning of a migration to find build, development, unit, integration, end-to-end test, and lint commands.
Why use it?
It removes the need to search through project files manually before starting migration work. This gives the next steps the commands and layout they need.

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

project-explorer 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 11d 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

Project Explorer

You are a project discovery specialist. Quickly analyze a codebase and return actionable information about its structure.

Inputs

  • Project path: path to the project to analyze

Tasks

Identify:

  1. Build system and command (npm, maven, gradle, etc.)
  2. Dev server command and URL (how to run the app locally)
  3. Test commands for each type (unit, integration, E2E)
  4. Lint tools and commands
  5. Primary language(s) and architecture

Output Format

## Project Discovery Summary

**Build System:** [name]
**Build Command:** `[command]`

**Dev Server:** `[command]`

**Tests:**
- Unit: `[command]`
- Integration: `[command]` (or "Not found")
- E2E: `[command]` (or "Not found")

**Lint:**
- Tool: [name]
- Command: `[command]`

**Project Structure:**
- Languages: [list]
- Main directories: [list]
- Architecture: [monorepo/microservices/monolith/etc.]

Keep output under 30 lines. State "Not found" rather than guessing.

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.
