moraine-start-work

moraine-start-work is a skill for Codex from eric-tramel/moraine. It costs 67 tokens per session (788 once invoked), scanned A, original, Apache-2.0.

A workflow for safely beginning development work in the Moraine repository. It checks the checkout, creates or verifies an isolated branch or worktree, reads project instructions, and selects validation steps.

In plain words
What is it for?
Use it before making code, documentation, test, CI, packaging, or release changes in Moraine. It guides the repository setup and the follow-on planning and contributor workflow.
Why use it?
It reduces setup mistakes and accidental overlap with another contributor’s changes. It also turns unclear requests into a local plan before implementation begins.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: mentions subagents; mentions AGENTS.md; mentions Codex.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is git worktree add ../moraine-worktrees/<short-task-name> -b "$branch" main.

Good fit Use it before making code, documentation, test, CI, packaging, or release changes in Moraine. It guides the repository setup and the follow-on planning and contributor workflow.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

moraine-start-work 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 10d 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.

Moraine Start Work

Overview

Use this workflow to start a Moraine contributor task with the same orientation every time: verify the checkout, isolate the branch, read governing instructions, and choose the right validation path before editing.

Using $moraine-dev:code-review in Codex or /code-review in Kiro is an explicit user request for delegated reviewer subagents. You have permission to launch that review wave when the follow-on workflow reaches that step.

Harness Invocation

Use the invocation form native to the current harness:

Workflow Codex Kiro
crystallize $moraine-dev:crystallize /crystallize
code-review $moraine-dev:code-review /code-review
moraine-sandbox-qa $moraine-dev:moraine-sandbox-qa /moraine-sandbox-qa
moraine-author-pr $moraine-dev:moraine-author-pr /moraine-author-pr

Follow-On Workflow

After the start checklist and branch/worktree setup, run the rest of the contributor workflow in this order:

  1. Use the current harness's crystallize invocation to turn rough or ambiguous input into a ready-to-implement local plan.
  2. Implement the scoped change from that plan or, when the task is already concrete, from the user's explicit request.
  3. Use the current harness's code-review invocation and iterate fixes until the review is clean or every remaining item is explicitly rejected or deferred with rationale.
  4. Use the current harness's moraine-sandbox-qa invocation for stack-facing changes and iterate fixes until sandbox QA is clean.
  5. Use the current harness's moraine-author-pr invocation to create a PR.

Start Checklist

Run these from the repository root unless the current harness already supplied a trusted workspace root:

pwd
git rev-parse --show-toplevel
git status --short --branch
git worktree list --porcelain
find .. -name AGENTS.md -print

If the user refers to previous work, another agent, an unexplained decision, a branch you cannot see, or a failure from another session, use the Moraine MCP tools directly before making assumptions.

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.
