explore-area

explore-area is a skill for Claude Code, Codex from huzaifa525/claude-code-optimizer. It costs 21 tokens per session (689 once invoked), scanned A, original, MIT.

A guide for exploring an unfamiliar code module, feature, or directory before changing it.

In plain words
What is it for?
Mapping files, finding entry points and tests, locating exports and definitions, and understanding a code area before implementation.
Why use it?
It reduces unnecessary reading by starting with a file list and then inspecting only relevant entry points, symbols, and dependencies.

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

explore-area 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 3d 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 — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Explore $ARGUMENTS using progressive disclosure to minimize token cost.

Progressive Disclosure (3 Layers)

Layer 1: File Index (cheapest — start here)

Get the file list WITHOUT reading contents:

# List all files in the target area
find [target] -type f -not -path '*/node_modules/*' -not -path '*/.git/*' | head -50

Or use Glob to find relevant files. From this list alone, identify:

  • Entry points (index., main., app.*)
  • Test files (.test., .spec.)
  • Config files
  • File count and general structure

Decision point: Do you now have enough context? If yes, skip to Return Format. If no, proceed to Layer 2.

Layer 2: Entry Points & Signatures (moderate cost)

Read ONLY entry points and key files. Use targeted reads:

  • Read index/main files to understand exports and module structure
  • Use Grep to find function signatures, class definitions, type exports
  • Map imports/exports to understand dependency graph
# Find exports
grep -rn "export" [target]/index.* 2>/dev/null
# Find class/function definitions
grep -rn "^export \(class\|function\|const\|interface\)" [target]/ 2>/dev/null

Decision point: Do you understand the module's API and structure? If yes, skip to Return Format. If no, proceed to Layer 3.

Layer 3: Deep Dive (expensive — only when needed)

Read full file contents, but only for files that are:

  • Directly relevant to the user's upcoming changes
  • Complex enough that signatures alone don't explain behavior
  • Containing patterns the user needs to follow

Use offset and limit for large files — read the relevant section, not the whole file.

Return Format

## Area: [name]

### Structure ([X] files)
- [file] → [purpose, 5 words max]

### Key Files (read these before editing)
- [file] → [what it does and why it matters]

### Dependencies
- Imports from: [external modules used]
- Exported to: [who consumes this module]

### Patterns to Follow
- [naming, structure, style patterns observed]
- [reference file] → follow this as template for new code

### Tests
- [test approach, test file locations, how to run]

### Gotchas
- [anything unusual, legacy code, known quirks]
- [things that look wrong but are intentional]

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.

explore-area is a skill published in the GitHub repository huzaifa525/claude-code-optimizer (9 stars, last pushed 5mo ago), licensed MIT. It adds 21 tokens to every session and 689 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
