Install it, pinned
mdr add etr/groundwork/work-on@git:20261023.5f1d1f9

Pins git:20261023.5f1d1f9 in mdr.lock. Pin the fingerprint instead.

skill to "execute a task", "work on task N", or "implement TASK-NNN" - orchestrates worktree isolation, TDD implementation, validation, and merge.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Execute Task Skill

Thin orchestrator that delegates to `plan-task`, `implement-task`, and `validate` skills for the three phases of task execution.

## Token Discipline

This skill orchestrates long multi-agent workflows. Every turn re-reads the full context window, so unnecessary turns are expensive.

1. **No narration turns.** Do not output text-only turns like "Let me load the task" or "Now I'll launch the plan agent." Combine text with a tool call in the same turn, or skip the text entirely.
2. **Batch tool calls.** When multiple tool calls are independent, issue them all in one turn.
3. **No waiting updates.** Do not output "Waiting for results..." turns. Wait silently until results arrive.
4. **Keep context lean.** Do not read file contents you won't use directly. Pass file paths to subagents and let them read in their own context windows.

## Delegation Ownership

Keep implementation and validation delegated to fresh, isolated contexts. The executor owns implementation and test monitoring; the validation coordinator owns its reviewer/fixer loop. The root owns dispatch, required decisions, and phase transitions.

How to install

The exact contents, by fingerprint
mdr add etr/groundwork/work-on@sha256:3c38c263eaeadd97

The line at the top of this page pins the label git:20261023.5f1d1f9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
