arunpaul-H/coding-agent-harness

Your coding agent's rules, enforced by code instead of prompts. Hooks block bad actions before they run; a committed baseline turns a deleted or skipped test into a red build. Zero dependencies. Hooks for Claude Code, gates for any CI.

# review before running: this installs third-party code
$ npx degit arunpaul-H/coding-agent-harness/.claude ./rig-coding-agent-harness  # inspect, then merge into .claude/

MCP servers are added to Claude Code at local scope; env vars are shown as YOUR_… placeholders — we never store values. Files are fetched with degit into a separate folder so you can review before merging.

Subagents (4)

explore
model: haiku
Read-only search across many files or naming conventions when only the conclusion is wanted, not the file dumps. Locates code; does not judge it.
implement
model: opus
Does ONE task from a handoff block inside a named READ-SET and ends by running the gate. Spawns nothing and commits nothing.
research
model: opus
Answers ONE question from the repo and the web and leaves a dated frozen research file behind. Writes that one file and nothing else.
review
model: inherit
Read-only review of a change already in the tree; returns ranked file:line findings and fixes nothing. Inherits the lead model because reviewing is judgement.
