What it does

Coding Agent is an agent skill from majiayu000/claude-skill-registry. Incremental development agent with TDD workflow. Use when implementing features one at a time, following test-driven development, making commits, or resuming development work.

Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `metadata.json`).

It sits in Testing & QA, covering Test-driven development. The repository describes itself as: Searchable Claude Code skills catalog with source-linked guides and generated registry artifacts. The licence is MIT.

When your agent uses it

Implementing features one at a time
Following test-driven development
Resuming development work

Example prompts

“/coding-agent”

Requirements

Python 3

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

ONE FEATURE PER SESSION: Focus prevents context exhaustion
TEST FIRST: Always write test before implementation
VERIFY BEFORE MARKING: Feature must actually pass
DESCRIPTIVE COMMITS: Reference feature ID and explain changes
MERGEABLE STATE: Code should always be in working state

What it can do on your machine

Read from SKILL.md and the folder at commit 000116a. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are python).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Coding Agent loads about 1.7k tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 124 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~47
When it runs · the whole SKILL.md, loaded when a task matches: ~1.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Coding Agent

Incremental development agent that implements features using test-driven development (TDD) in subsequent sessions after initialization.

Quick Start

Start a Coding Session

python

from scripts.coding_agent import CodingAgent

agent = CodingAgent(project_dir)
context = await agent.start_session()
print(f"Session {context.iteration} started")

Implement Next Feature

python

feature = await agent.select_next_feature()
result = await agent.implement_feature(feature)

if result.success:
    await agent.mark_feature_complete(feature)
    await agent.commit_work(f"Implement: {feature.description}")
