project-discovery

project-discovery is a skill for Claude Code, Codex from ntaffzii/Skill-Agents. It costs 58 tokens per session (412 once invoked), scanned A, original, MIT.

A structured way to understand an unfamiliar software project before changing or planning it. It examines key files, maps the system, and records uncertainties, risks, and missing information.

In plain words
What is it for?
Use it for architecture reviews, onboarding, migrations, implementation planning, technology choices, or project summaries. It can identify entry points, data flow, external services, build and test commands, and readiness concerns.
Why use it?
Starting implementation without understanding a project can conflict with its conventions or overlook important modules, services, tests, and deployment details.

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 7d 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 Discovery

Build a practical understanding of a project before proposing or making changes.

Workflow

  1. Identify the goal

    • Determine whether the user needs an overview, architecture summary, stack analysis, risk assessment, implementation plan, migration direction, or onboarding notes.
  2. Inspect high-signal files

    • Read README.md, project instructions, package manifests, lockfiles, docs, architecture notes, CI config, test config, and main entry points.
    • Prefer actual files over guesses — the research-methodology source-tier idea applies here too: a file in the repo outranks a README's description of what the repo does, which outranks an outside blog post about the project.
  3. Map the system

    • Identify core modules, data flow, user-facing surfaces, external services, build commands, test commands, deployment hints, and local conventions.
    • Note areas that need follow-up inspection instead of pretending certainty.
  4. Assess readiness

    • Call out missing docs, unclear ownership, brittle tests, risky dependencies, weak validation, or hidden configuration.
    • Keep recommendations incremental.
  5. Report

    • Respond in the user's language.
    • Link to files when possible.
    • End with a practical next step.

Rules

  • Do not propose broad rewrites before understanding local patterns.
  • Distinguish verified facts from assumptions.
  • Keep the report useful for the next action, not encyclopedic.

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.
