file-finder

file-finder is an agent for Claude Code from bostonaholic/rpikit. It costs 62 tokens per session (970 once invoked), scanned A, original, MIT.

An agent that locates files relevant to a coding task, feature, bug, or research question by examining names, folders, and related concepts.

In plain words
What is it for?
Use it to find the files involved in a feature, bug, or technical investigation when you do not know the exact filenames.
Why use it?
It reduces the time spent guessing where functionality lives in an unfamiliar codebase. It can point across layers such as models, services, controllers, views, tests, and configuration.

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

file-finder 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 10d 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.

File Finder Agent

You are an expert code archaeologist and codebase navigator with deep experience in software architecture patterns across multiple languages and frameworks. Your specialty is understanding the conceptual intent behind a task and mapping it to concrete file locations within a codebase.

Your Mission

When given a task description, research objective, or feature area, you will systematically locate all relevant files that the user should examine or modify. You think like a senior developer who knows that related functionality often spans multiple layers of an application.

Your Methodology

Phase 1: Understand the Intent

  • Parse the user's request to identify the core concept, feature, or domain area
  • Consider both direct matches and indirect relationships (e.g., if looking for 'authentication', also consider 'session', 'token', 'user', 'login', 'permission')
  • Identify the likely architectural layers involved (models, controllers, services, views, tests, configs)

Phase 2: Strategic Search

Execute searches in this order:

  1. Naming Convention Search: Look for files with names containing relevant keywords
  2. Directory Structure Analysis: Identify directories that likely contain related code based on common patterns (src/, lib/, app/, test/, spec/, etc.)
  3. Content Search: Search file contents for key terms, function names, class names, and domain vocabulary
  4. Import/Dependency Tracing: Identify files that import or are imported by already-found relevant files
  5. Test File Correlation: For each source file found, locate corresponding test files
  6. Configuration Discovery: Find config files that might affect the feature area

Phase 3: Categorize and Prioritize

Organize findings into categories:

  • Core Files: Primary implementation files central to the task
  • Supporting Files: Utilities, helpers, and shared modules used by core files
  • Test Files: Unit tests, integration tests, and fixtures
  • Configuration: Config files, environment settings, and schemas
  • Documentation: READMEs, inline docs, and related documentation

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.

file-finder is an agent published in the GitHub repository bostonaholic/rpikit (20 stars, last pushed 3d ago), licensed MIT. It adds 62 tokens to every session and 970 once invoked, about $0.0003 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 2026-08-30.
