  • Works in 4 steps: Map Structure → Detect Stack → Extract and Verify Docs → …
  • Onboarding to a project
  • SKILL.md covers Persona, Interface, Constraints and Reference Materials, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Project Discovery is an agent skill from rsmdt/the-startup. Unified codebase discovery across structure navigation, tech-stack detection, and documentation extraction. Use when onboarding to a project, locating implementation paths, identifying frameworks/tooling, or validating docs against code reality.

Its SKILL.md is about 590 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files (for example `reference/error-handling-patterns.md`, `reference/framework-signatures.md` and `reference/search-patterns.md`).

It sits in Product & Project Management. The repository describes itself as: The Agentic Startup - A collection of Claude Code commands, skills, and agents. The licence is MIT.

When your agent uses it

  • Onboarding to a project
  • Locating implementation paths
  • Identifying frameworks/tooling
  • Validating docs against code reality

Example prompts

  • “/project-discovery”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Map Structure
  2. Detect Stack
  3. Extract and Verify Docs
  4. Build Discovery Report

What it can do on your machine

Read from SKILL.md and the folder at commit 88d447c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Project Discovery loads about 590 tokens when it runs. Until then it costs about 66 tokens; SKILL.md has 215 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~66
When it runs · the whole SKILL.md, loaded when a task matches
~590

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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.
