ai-dev-standards: Agent for Claude Code

.claude/agents/usage-examples.md

usage-examples is an agent for Claude Code from daffy0208/ai-dev-standards. It costs 0 tokens per session (3,201 once invoked), scanned A, original, MIT.

A collection of examples showing which coding agents to use for common development work. It includes onboarding a new repository, investigating bugs, implementing features, reviewing code, and planning migrations.

In plain words
What is it for?
Use it as a reference for exploring an unfamiliar project, refactoring, security audits, performance work, documentation, architecture analysis, and code-review preparation.
Why use it?
It gives developers concrete prompts and expected results when they are unsure how to divide a task between agents.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: mentions CLAUDE.md.

This is daffy0208/ai-dev-standards's own configuration. It tells Claude Code how to work on ai-dev-standards itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ai-dev-standards configures →

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

usage-examples 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.

New Repository Onboarding

Scenario

You've just cloned a new React/Node.js project and need to understand it quickly.

Approach

Phase 1: Quick Overview (5 minutes)

Agent: Explore (Quick)
Task: "Give me an overview of this project - what it does,
       tech stack, and main entry points"

Expected Output:
- Project purpose
- Tech stack (React, Node, PostgreSQL)
- Entry points (index.tsx, server.ts)
- Directory structure

Phase 2: Deep Dive on Key Areas (30 minutes)

Agent: Explore (Medium)
Task: "Explore the authentication system - how users log in,
       session management, and authorization checks"

Expected Output:
- Auth flow diagram
- Components involved
- API endpoints
- Security measures

Phase 3: Get Started (Ongoing)

Agent: General-Purpose
Task: "Set up my local development environment following
       the project conventions"

Actions:
- Install dependencies
- Configure environment
- Run tests
- Start dev server

Bug Investigation

Scenario

Users report authentication failing with special characters in passwords.

Approach

Phase 1: Locate Code (5 minutes)

Agent: General-Purpose
Task: "Find all code related to password validation and
       authentication, especially where user input is processed"

Tools Used:
- Grep for "password", "validation", "auth"
- Read auth-related files

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.

usage-examples is an agent published in the GitHub repository daffy0208/ai-dev-standards (38 stars, last pushed 10mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 3,201 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 2026-08-30.
