project-md-refresh
Analyze the current repository and create or refresh .claude/PROJECT.md to match the project. Use when PROJECT.md is missing, stale, or the user asks to generate/update project-specific rules, structure, commands, or architecture details.
When & Why to Use This Skill
The project-md-refresh skill automates the creation and maintenance of the `.claude/PROJECT.md` file by performing a comprehensive analysis of your repository. It identifies the technology stack, maps directory structures, and extracts essential development commands from configuration files. By ensuring your AI assistant has an accurate, evidence-based 'source of truth,' this skill minimizes context-related errors and optimizes the AI's ability to assist with project-specific coding tasks.
Use Cases
- Onboarding AI to New Repositories: Automatically generate a detailed project overview, including tech stack and entry points, to give Claude immediate and accurate context.
- Synchronizing Stale Documentation: Refresh the PROJECT.md file after major refactors or dependency changes to ensure the AI's understanding of the architecture remains up-to-date.
- Standardizing Development Workflows: Extract and document build, test, and lint commands from files like package.json or Makefile to provide a unified command reference for the agent.
- Mapping API and Data Patterns: Automatically locate controllers, routes, and models to help the AI understand the data flow and backend structure of the application.

PROJECT.md Refresh
Goal
Create or update .claude/PROJECT.md with accurate, evidence-based project details.
Workflow
Locate the base file.
- If
.claude/PROJECT.mdexists, use it as the base; preserve custom rules and update facts. - If missing, create
.claude/if needed and copyassets/PROJECT.template.mdto.claude/PROJECT.md.
- If
Collect signals from the repository.
- Read
README.mdand any project docs. - Identify the stack from config files:
package.json,pyproject.toml,go.mod,Cargo.toml,build.gradle,pom.xml,Gemfile,requirements.txt,Makefile, orTaskfile. - Extract run/build/test/lint commands from scripts or tooling.
- Inspect the top-level directory structure and key entrypoints.
- Locate API routes/controllers and data models (search for
route,router,controller,handler,model,schema). - Find auth configuration (search for
auth,jwt,session,oauth). - Note environment variable usage (search for
ENV,process.env,os.environ,dotenv).
- Read
Update
PROJECT.mdsections.- Fill the overview (name, stack, primary language).
- Summarize core rules and conventions.
- Document directory structure (top-level + key subdirectories).
- Document API/data patterns, auth, and docs paths.
- Add concrete commands for dev/build/lint/test/typecheck.
Output.
- Save
.claude/PROJECT.md. - Provide a short summary and list any gaps/questions.
- Save
Guardrails
- Do not invent details; base every statement on files found.
- If information is missing, add TODOs or ask for confirmation.
- Keep content concise and project-specific.
