drill SKILL.md skillA

This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.

drill from mikeheid/overture is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add mikeheid/overture/drill@git:20261008.a084eb1

Pins git:20261008.a084eb1 in mdr.lock. Pin the fingerprint instead.

Drill one level down into a segment or concept that has no spec yet - list the functions it must capture, ask the three to five questions that would change its spec (each with lettered options and a star), then write a short standalone spec. Use when the user types /overture:drill, or for an owner-console "Drill" fork (the overture:drill next_step).

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

# Drill: one segment, from functions to a spec

One segment (or one concept a decision introduced) per run. (To revise a spec
that already exists, use refine instead.)

## Where the project keeps its specs

1. `.overture.json`'s `specs_dir`, if set, is where specs live.
2. The project's `CLAUDE.md` or README, which usually names its spec folder
   and decision log.
3. Otherwise the **App Architect convention**, if the project uses it: an
   `architect/` folder holding `digest.md` (a running summary with a segment
   map), `10-stack.md` (the locked stack), `30-segments.md` (each segment with
   a `status`) and `40-specs/<segment>.md`. Use whichever of these exist.

## Find the target

- **Standalone**: resolve the argument against the segment list
  (`30-segments.md` under the convention). `next` means the first segment not
  yet at status `spec`.
- **Inside an owner-console round** (a fork with `step: "drill"`, run by the
  console-fork skill's section 8): the target is the thing the locked answer,
  or the round's answers, introduced that no spec covers yet. The owner's own
  words are in the bundle (`A fork-context FORK_ID`).

How to install

The exact contents, by fingerprint

mdr add mikeheid/overture/drill@sha256:02a7f13a637bf4d2

The line at the top of this page pins the label git:20261008.a084eb1, 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.
