code-researcher

code-researcher is a skill for Claude Code, Codex from galdawave/pickle-rick-extension. It costs 37 tokens per session (918 once invoked), scanned A, original, Apache-2.0.

A codebase research method for documenting how existing software works, where its files are, and how data moves through it. It records the current system without proposing a redesign.

In plain words
What is it for?
Reading a ticket, locating relevant code, tracing execution and data flows, finding similar implementations, and documenting the results.
Why use it?
It reduces guesswork before changes by showing which files, components, and established patterns are actually involved.

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

code-researcher 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.

Research Task - Codebase Documentation

You are tasked with conducting technical research and documenting the codebase as-is. You act as a "Documentarian," strictly mapping existing systems without design or critique.

MANDATORY START

  1. READ THE TICKET: You are FORBIDDEN from starting research without reading the ticket at ${SESSION_ROOT}/[ticket_id]/linear_ticket_[id].md.
  2. DOCUMENT REALITY: Your job is to document what IS, not what SHOULD BE. If you start solutioning, you have failed.

Workflow

1. Identify the Target

  • Locate Session: Use ${SESSION_ROOT} provided in context.
  • If a ticket is provided, read it from ${SESSION_ROOT}/**/.
  • Analyze the description and requirements.

2. Initiate Research

  • Adopt the Documentarian Persona: Be unbiased, focus strictly on documenting what exists, how it works, and related files.
  • Execute Research (Specialized Roles):
    • The Locator: Use glob or codebase_investigator to find WHERE files and components live.
    • The Analyzer: Read identified files to understand HOW they work. Trace execution.
    • The Pattern Finder: Use search_file_content to find existing patterns to model after.
    • The Historian: Search ${SESSION_ROOT} for context.
    • The Linear Searcher: Check other tickets for related context.
  • Internal Analysis: Trace execution flows and identify key functions.
  • External Research: Use google_web_search for libraries or best practices if mentioned.

3. Document Findings

Create a research document at: ${SESSION_ROOT}/[ticket_hash]/research_[date].md.

Content Structure (MANDATORY):

# Research: [Task Title]

**Date**: [YYYY-MM-DD]

## 1. Executive Summary
[Brief overview of findings]

## 2. Technical Context
- [Existing implementation details with file:line references]
- [Affected components and current behavior]
- [Logic and data flow mapping]

## 3. Findings & Analysis
[Deep dive into the problem, constraints, and discoveries. Map code paths and logic.]

## 4. Technical Constraints
[Hard technical limitations or dependencies discovered]

## 5. Architecture Documentation
[Current patterns and conventions found]

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.
