build-unplanned SKILL.md skillA
build-unplanned from etr/groundwork is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add etr/groundwork/build-unplanned@git:20260912.480a145Pins git:20260912.480a145 in mdr.lock. Pin the fingerprint instead.

Build a feature from description with worktree isolation and TDD. Usage /groundwork:build-unplanned "Add user login".
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
# Build Unplanned Feature
Thin orchestrator for ad-hoc feature development without existing task definitions. Delegates to `plan-task` (blurb mode), `implement-task`, and `validate`.
## 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 understand your feature" or "Now I'll dispatch implementation." 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.
## Pre-flight: Model Recommendation
**Your current effort level is `{{effort_level}}`.**
Skip this step silently if effort is `high`, `xhigh`, or `max` (the scale is `low` < `medium` < `high` < `xhigh` < `max`, so `xhigh` and `max` are already above `high`) AND you are Sonnet or Opus.

How to install
mdr add etr/groundwork/build-unplanned@sha256:f804f7e27aae5c28The line at the top of this page pins the label git:20260912.480a145, 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.
