Ralph Loop based autonomous development loop. An agent skill from jh941213/my-cc-harness.

  • Works in 4 steps: Configuration Collection → Loop Initialization → Iteration Execution (every session) → …
  • Tasks that involve Autonomous loops
  • SKILL.md covers Core Principle, Phase 0: Configuration…, Phase 1: Loop Initialization and Phase 2: Iteration Execution…, plus 5 more sections
  • Calls git, python3 and npm

What it does

Autodev is an agent skill from jh941213/my-cc-harness. Ralph Loop based autonomous development loop. A Stop Hook intercepts session termination and completes PRD items one by one with automatic commits. Triggers: "autodev", "autonomous development", "run overnight", "ralph loop", "auto development" Anti-triggers: "implement it yourself", "do it once", "manual"

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows, covering Autonomous loops and PRD writing.

When your agent uses it

  • Tasks that involve Autonomous loops
  • Tasks that involve PRD writing

Example prompts

  • “autodev”
  • “autonomous development”
  • “run overnight”
  • “/autodev”

Requirements

  • Python 3
  • Pre-approved tools (allowed-tools): Read, Write, Edit, Bash, Grep, Glob, Agent

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Configuration Collection
  2. Loop Initialization
  3. Iteration Execution (every session)
  4. Completion Report

What it can do on your machine

Read from SKILL.md and the folder at commit e9210e2. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Write
    • Edit
    • Bash
    • Grep
    • Glob
    • Agent

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • git
    • python3
    • npm
    • vitest
    • make

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git and npm, which can reach the network depending on how they are called.

    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

Autodev loads about 1.5k tokens when it runs. Until then it costs about 79 tokens; SKILL.md has 293 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~79
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Read, Write, Edit, Bash, Grep, Glob, Agent

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 293 words (~1,530 tokens).

“Stop Hook based autonomous development loop. Completes PRD/checklist items one by one with automatic commits. Leave it running overnight and a PR is waiting when you arrive at work.”
