What is project-explorer?

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.

Use it at the beginning of a migration to find build, development, unit, integration, end-to-end test, and lint commands.

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.

project-explorer — Agent for Claude Code by konveyor-ecosystem

Install

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.

Clone the repo

git clone --depth 1 https://github.com/konveyor-ecosystem/playpen-pf-mig-skills

Made for: Claude Code.

Per session 35 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 386 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00035	$0.00386
Opus 5.5	$0.00014	$0.00154
Sonnet 5.5	$0.00007	$0.00077
Haiku 4.5	$0.00003	$0.00039

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 2mo 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:

Build system and command (npm, maven, gradle, etc.)
Dev server command and URL (how to run the app locally)
Test commands for each type (unit, integration, E2E)
Lint tools and commands
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.
