overview-exploration

overview-exploration is a skill for Claude Code from mnthe/hardworker-marketplace. It costs 36 tokens per session (1,547 once invoked), scanned A, original, MIT.

A quick guide for understanding a software project at the start of a larger task. It checks the project type, directory structure, entry points, and existing code patterns.

In plain words
What is it for?
Use it to identify frameworks, dependencies, source folders, application entry points, and patterns such as authentication or session handling.
Why use it?
It gives agents enough context to plan changes that fit the project instead of guessing where or how to work.

Skill for Claude Code

Written for Claude Code: user-invocable in frontmatter. Also seen: reads .claude/ paths; mentions CLAUDE.md.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

overview-exploration 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 12d 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.

Overview Exploration Skill

Quick project overview exploration executed directly without agent spawn.

When to Use

  • At the start of ultrawork sessions (exploration phase)
  • When project structure understanding is needed
  • Context collection before targeted exploration

Execution Steps

Step 1: Detect Project Type

Check for language/framework config files:

Glob(pattern="package.json")      # Node.js/JS
Glob(pattern="go.mod")            # Go
Glob(pattern="requirements.txt")  # Python
Glob(pattern="Cargo.toml")        # Rust
Glob(pattern="pom.xml")           # Java/Maven

Read discovered files to understand dependencies and framework.

Step 2: Explore Directory Structure

# Top-level structure
Glob(pattern="*", path=".")

# Main source directories
Glob(pattern="src/*")
Glob(pattern="app/*")
Glob(pattern="lib/*")

Step 3: Identify Entry Points and Patterns

# Find entry points (language-specific)
Grep(pattern="export default|module.exports", type="ts")
Grep(pattern="def main|if __name__", type="py")
Grep(pattern="func main", type="go")

# Check for existing patterns
Grep(pattern="auth|login|session", output_mode="files_with_matches")

Step 4: Quantitative Data Collection

Beyond descriptive findings, collect measurable data that enables informed planning decisions.

Test file count:

# Count test files in project
find . -name "*.test.*" -o -name "*.spec.*" | wc -l

# Check for test configuration
ls jest.config* vitest.config* .bun* 2>/dev/null

Key interface signatures:

# Extract exported interfaces and types
grep -A3 "export.*interface\|export.*type\|export.*function" src/ --include="*.ts" -rn | head -20

File line counts for main source files:

# Line counts for relevant source files
wc -l src/**/*.ts 2>/dev/null | tail -5

Include these metrics in your exploration output under a "Quantitative Data" subsection (see Output Format below).

Step 5: Read Documentation

Files

What ships with it

2 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.
