guideline-reader

guideline-reader is a skill for Claude Code, Codex from doordash-oss/agentic-orchestrator. It costs 26 tokens per session (619 once invoked), scanned A, original, Apache-2.0.

A skill that finds and applies language-specific coding guidelines for a repository. These guidelines describe preferred practices, patterns, and conventions for writing or reviewing code.

In plain words
What is it for?
Use it before writing or reviewing code, especially when the repository contains rules for the programming language being used.
Why use it?
It helps prevent code that conflicts with the project's existing style or rules. It also points to more specific guidance for errors, concurrency, naming, interfaces, and tests.

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

guideline-reader 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 1mo 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 — 44 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Guideline Reader

You have access to language-specific coding guidelines for the target repository. The guidelines discovery table is already inlined in your prompt under "## Available Language Guidelines" — scan it now to see which languages are available.

The guidelines are organized as a hierarchy of markdown documents. Each language has a top-level index.md that links to category-specific files containing the actual rules. Do not stop at the top-level index — it is an index, not the guidelines themselves.

When to Read Guidelines

Consult the guidelines before you:

Situation Read from these categories
Write new code All categories matching the language(s) in use
Handle errors error-handling/ — wrapping, sentinel errors, error grading
Use goroutines, channels, or mutexes concurrency/ — patterns, context propagation, synchronization
Name variables, functions, or packages naming-and-style/ — naming conventions, formatting rules
Design interfaces or inject dependencies abstractions/ — composition, interface design, DI patterns
Write or modify tests testing/ — table-driven tests, mocks, benchmarks, fuzz tests
Structure packages or modules project-organization/ — package layout, module boundaries
Work with slices, maps, or structs data-types-and-memory/ — allocation patterns, value vs pointer semantics
Use stdlib packages (io, net/http, etc.) standard-library/ — idiomatic usage of standard library

How to Navigate

  1. Scan the inlined guidelines table in your prompt — it shows each language and the path to its index.md
  2. Read the index.md for the language you are working with — it contains a Category Index table with "When to Read" guidance
  3. Read the category index.md for each category relevant to your task (e.g., error-handling/index.md)
  4. Read deeper topic files if the category index references them and they are relevant to your work
  5. Only read what you need — typically 2-4 category files per task

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.
