r

r is a command for Claude Code from loschenbd/claude-agent-boilerplate. It costs 0 tokens per session (504 once invoked), scanned A, original, MIT.

A focused codebase research command for collecting facts before planning or implementation. It looks for relevant files, current patterns, data flows, types or schemas, and possible conflicts, without changing code.

In plain words
What is it for?
Use it with a feature ticket or specific technical questions to investigate how the affected part of a codebase currently works.
Why use it?
It reduces uncertainty about a proposed change and keeps the research phase separate from recommendations and implementation.

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

r 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 5d 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.

The opening of the file, as written. The whole thing — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Run a focused research pass on the codebase before any planning or implementation begins.

Instructions

You are in the Research phase of QRSPI. Your job is to gather objective facts about the codebase — no recommendations, no design opinions, no code changes.

The user will provide either:

  • A feature ticket / task description, OR
  • A set of targeted questions they've already written

If given a ticket: Extract the key technical unknowns from it, then research those. Do not let the ticket bias your findings — report what is, not what the ticket wants.

If given questions: Answer each question with codebase evidence.

What to produce

Spawn an Explore subagent to investigate. Direct it to find and document:

  1. Relevant files — exact paths for every file that touches the affected area
  2. Current patterns — how similar things are already done in this codebase (naming, structure, conventions)
  3. Data flows — how data moves through the affected area
  4. Existing types/schemas — relevant TypeScript types, Zod schemas, database table shapes
  5. Potential collision points — anything that could conflict with or be affected by changes in this area

Output format

Write findings to plans/<task-slug>/research.md using this structure:

# Research: <task name>

## Relevant Files
- `path/to/file.ts` — what it does and why it matters here

## Current Patterns
- <pattern name>: <how it works, with file:line references>

## Data Flow
<trace the relevant flow end-to-end>

## Types & Schemas
- <type/schema name>: `path/to/file.ts:line`

## Collision Points
- <anything that could break or conflict>

## Open Questions
- <anything the research couldn't resolve — flag for Design Discussion>

Rules

  • Facts only. No implementation suggestions in this doc.
  • Cite everything. Every claim should reference a file path and line number.
  • Keep context lean. Use the Explore subagent for grep/glob/read so the main context stays clean.
  • Stop here. Do not proceed to planning. Surface the research doc to the user for review.

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.

r is a command published in the GitHub repository loschenbd/claude-agent-boilerplate (2 stars, last pushed 4mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 504 tokens. 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 2026-09-04.
