Skills reference
Every skill in this repository — who starts it, what it takes and what it produces — where the skill files live, and the two skills taken unchanged from an upstream repository. It is the reference page under Engineering; Running the flow with skills explains how they are used together.
Where skills live
- .claude/
- skills/

- SKILL.md — frontmatter (
name,description, sometimesdisable-model-invocation: true), then the instructions

AGENTS.md
There is one copy of each skill; edit it under .claude/skills/.
The skills
The operator starts a stage; agents reach for the skills that serve one. That
split is machine-readable: an operator only skill carries
disable-model-invocation: true in its frontmatter, so an agent never starts
it on its own.
Operator only
The operator's slash command starts these.
| Skill | Takes | Produces |
|---|---|---|
design |
An idea for how the system should change. | A conversation until the understanding is shared, then — when asked — box docs and constraints written on design/<name>. |
plan |
docs/plan/00-prototype.md on the design branch. |
A story the operator approves, and one ticket file per step in docs/plan/, with id, blocked-by and boxes front-matter. |
build |
An approved plan. | Lanes run by forks in their own worktrees, merged --no-ff one at a time; docs/plan/ deleted; a design-branch pull request to main reviewed at the drift bar; after the operator's merge, the branches deleted and the retro. |
hack |
A bug or small change. | Aligned, then built with the operator in their checkout on hack/<name>; docs, tests and gates paid before a pull request to main. |
improve-codebase-architecture |
The codebase, or a direction the operator names. | Deepening opportunities as an HTML report in the system temp folder, then a discussion of the one the operator picks. Upstream skill. |
Operator or agent
An agent may also reach for these when its work calls for one.
| Skill | Who reaches for it | Takes | Produces |
|---|---|---|---|
prototype |
The operator asks, and the design session forks itself to run it | A settled design on its design branch. | One end-to-end path in real code with tests, built in thirty measured minutes on prototype/<name>; the report docs/plan/00-prototype.md; the branch merged into the design branch and deleted. |
implement-ticket |
A lane's fork | One ticket, in its own worktree, on a branch off the design branch. | The ticket built red-green, gates green, self-reviewed at the task bar; a branch ready to merge and a report of what changed and what was left alone. |
review |
The operator, or any agent | A branch or pull request and its target. | Findings, each demonstrated, against the task bar (into a design branch) or the drift bar (into main). |
retro |
The session that coordinated build |
A design branch that has merged into main. |
A short report in chat: one line per stage, its cost and what it caught. Writes nothing. |
align |
Used inside every stage | A conversation. | Shared understanding, one topic at a time. Writes no files and authorizes nothing. |
documentation |
The operator, or any agent | A documentation subject and its scope. | Pages written to the five-layer reading hierarchy, from landing to reference. |
presentation |
The operator, or any agent | A deck to make or improve, its purpose and its audience. | The story agreed with the operator (shaped with marketing and developer-relations viewpoints), slides of one headline and one picture each, speaker notes in plain English, every slide checked as an image. |
codebase-design |
The operator, or any agent | Code being designed or restructured. | A vocabulary — module, interface, depth, seam, adapter, leverage, locality — and principles for deep modules. Upstream skill. |
AGENTS.md names when the upstream architecture skill is used: architecture
reviews, alongside review, after reading its integration note.
The upstream skills
codebase-design and improve-codebase-architecture are copied from the
mattpocock/skills repository. Each
folder's UPSTREAM.md records:
- Source and pinned commit — the skill's folder in that repository at
commit
5beb35b040e3de97e54fa9e386d7e42d15c295c2. - What is unchanged —
SKILL.md,DEEPENING.md,DESIGN-IT-TWICE.mdandagents/openai.yamlincodebase-design;SKILL.md,HTML-REPORT.mdandagents/openai.yamlinimprove-codebase-architecture. - Licence — the upstream repository's MIT licence at that commit, copied
as each folder's
LICENSE.
The upstream files assume a project that keeps a GLOSSARY.md, ADRs under
docs/adr/ and its own grilling and domain-modeling skills. devpage has
none of those, so improve-codebase-architecture/UPSTREAM.md adds a
devpage integration note, to be read before the upstream skill, that maps
each assumption onto this repository: box glossaries and box docs instead of
GLOSSARY.md and ADRs (and never create those paths), align instead of
grilling, design instead of domain-modeling. devpage's review scope,
evidence bar and permission to write govern both skills, and installing them
authorizes no scan, design update or implementation. No procedure for moving
them to a newer upstream commit is written down yet.
