DGE Work Node

Use this skill to implement one ready atomic node.

Purpose

Execute only the selected node's scope, then produce evidence for /dge-verify.

Core rules

1. Work on exactly one node unless the user explicitly asks for a batch.
2. Do not start a node whose dependencies are not complete.
3. Keep the node's validation contract visible throughout execution.
4. Do not mark the node done; /dge-verify owns completion.
5. Update graph status to in_progress when work starts and review when implementation is ready for verification.
6. This skill is a fixed procedure, not a starting point for extra self-invented review, hardening, or validation rounds. If you find yourself about to add a step that is not listed under Workflow below, stop — it belongs in a follow-up suggestion (step 9) or in /dge-review / /dge-verify, not here.

Workflow

1. Read delivery-graph/graph.json.
2. Locate the requested node.
3. Check dependencies.
4. Read linked requirements and validation contract.
5. Implement the smallest change that satisfies the node's validation contract — nothing else. Do not add refactors, hardening, "while I'm in here" fixes, or other DX/contract improvements beyond what the contract requires, even if they are cheap or clearly beneficial. If you notice an adjacent improvement opportunity, do not implement it — note it as a follow-up suggestion in step 9 instead.
6. Run each check named in the node's validation contract items, exactly once per check. "Focused validation" means only those checks — not the repository's full test/build baseline, not a broader sanity sweep, and not a second pass "just to be sure." Re-running a check in the same node execution is only valid if you changed code in between (e.g. a check failed, you fixed the cause, you run that check again); re-running a check that already passed, with no intervening code change, is not part of this workflow.
7. Save evidence under delivery-graph/evidence/NODE-###/.
8. Update node status to review.
9. Report changed files, evidence paths, and remaining validation. If you noticed adjacent improvement opportunities while implementing (step 5), list them here as suggested follow-ups — do not implement them in this run.

Stop condition

Once step 7 (evidence saved) and step 8 (status set to review) are done, this skill's work is complete. Do not add another review pass, another validation round, or additional unrequested changes after this point — even if you think of something that seems worth checking. Further review of this node's changes happens in /dge-review or /dge-verify, invoked separately by the user or by the calling skill. Report and stop.

Output

Follow the shared output convention (see skills/README.md): lead the final reply with a bold one-line synthesis (e.g. "NODE-### implemented, evidence captured, ready for verify"), then the demand's progress indicator (see skills/README.md), then changed files, evidence paths, and remaining validation, then a ## Next block: /dge-verify NODE-###.

Evidence format

At minimum, create:

• delivery-graph/evidence/NODE-###/summary.md

Include:

• node id
• commands run
• results
• changed files
• links to PR/checks, if available
• known limitations
