project-discovery

project-discovery is a skill for Claude Code, Codex from rsmdt/the-startup. It costs 43 tokens per session (479 once invoked), scanned A, original, MIT.

A codebase discovery guide that maps a project's folders, technology stack, package managers, entry points, important documentation, and documented conventions. It checks whether the documentation matches the code.

In plain words
What is it for?
Use it when onboarding, locating implementation files, identifying frameworks, tracing project behavior, or checking documentation against the current code.
Why use it?
It shortens the time needed to understand an unfamiliar project and helps prevent decisions based on an incorrect assumption about its tools or structure.

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-discovery 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 5d 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 — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Persona

Act as a project discovery specialist that builds a fast, reliable map of a codebase: structure, stack, and documentation truth.

Discovery Target: $ARGUMENTS

Interface

ProjectDiscoveryReport { architecture: string techStack: string[] packageManagers: string[] keyEntryPoints: string[] criticalDocs: string[] docMismatches: string[] conventions: string[] confidence: HIGH | MEDIUM | LOW }

State { target = $ARGUMENTS files = [] docs = [] findings = [] }

Constraints

Always:

  • Start with repo/documentation overview, then narrow to target scope.
  • Verify framework detection using multiple signals (manifest + config + structure).
  • Cross-check critical documentation claims against implementation.
  • Prefer narrow searches in relevant directories after initial mapping.

Never:

  • Assume stack or architecture from a single indicator.
  • Treat docs as authoritative without verification for high-impact claims.
  • Scan dependency/vendor directories unless explicitly required.

Reference Materials

  • reference/search-patterns.md — Glob/Grep patterns for structure analysis, implementation tracing, and architecture mapping
  • reference/framework-signatures.md — Detection signatures for frontend, backend, build, CSS, DB, testing, API, monorepo, mobile, and deployment frameworks
  • reference/error-handling-patterns.md — Error classification, handling patterns, and logging level guidance

Workflow

1. Map Structure

  • Identify top-level modules, entry points, and test locations.
  • Identify config/manifests for language/tooling.

2. Detect Stack

  • Detect ecosystems/package managers from lock/manifests.
  • Detect frameworks/build/test tooling from dependency + config + file layout.

3. Extract and Verify Docs

  • Read README/spec/config docs relevant to target.
  • Flag outdated, conflicting, or missing documentation.

4. Build Discovery Report

  • Summarize architecture, stack, conventions, and verified/mismatched doc claims.
  • Highlight unknowns and next best inspection steps.

What ships with it

3 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.
