Deepen Architecture

Surface architectural friction and propose deepening opportunities — refactors that turn shallow modules into deep ones. The aim is testability and AI-navigability.

Distinct from define-language and model-domain: Use this skill to find module-level refactoring opportunities in the codebase. Use define-language to produce a canonical glossary of terms. Use model-domain to stress-test a plan through a domain-model interview.

HARD GATE — Deep modules must solve a forcing function, not just be "nice abstractions." If you cannot articulate why the abstraction exists, it is premature.

Glossary

Use these terms exactly in every suggestion. Consistent language is the point — don't drift into "component," "service," "API," or "boundary." Full definitions in LANGUAGE.md.

Module — anything with an interface and an implementation (function, class, package, slice).
Interface — everything a caller must know to use the module: types, invariants, error modes, ordering, config. Not just the type signature.
Implementation — the code inside.
Depth — leverage at the interface: a lot of behaviour behind a small interface. Deep = high leverage. Shallow = interface nearly as complex as the implementation.
Seam — where an interface lives; a place behaviour can be altered without editing in place. (Use this, not "boundary.")
Adapter — a concrete thing satisfying an interface at a seam.
Leverage — what callers get from depth.
Locality — what maintainers get from depth: change, bugs, knowledge concentrated in one place.

Key principles (see LANGUAGE.md for the full list):

Deletion test: imagine deleting the module. If complexity vanishes, it was a pass-through. If complexity reappears across N callers, it was earning its keep.
The interface is the test surface.
One adapter = hypothetical seam. Two adapters = real seam.

This skill is informed by the project's domain model — specs/tech-architecture/tech-stack.md and any specs/adr/. The domain language gives names to good seams; ADRs record decisions the skill should not re-litigate. See CONTEXT-FORMAT.md and ADR-FORMAT.md.

Process

1. Explore

Read existing documentation first:

specs/tech-architecture/tech-stack.md (or specs/tech-architecture/tech-stack.md + each specs/tech-architecture/tech-stack.md in a multi-context repo)
Relevant ADRs in specs/adr/

If any of these files don't exist, proceed silently — don't flag their absence or suggest creating them upfront.

Look-here-first (churn heuristic): Before organic exploration, rank candidate modules by recent commit frequency. High-churn files are architectural friction magnets — start there.

bash scripts/bp-churn-rank.sh --since 90.days --limit 20

Then use the Agent tool with subagent_type=Explore to walk the codebase. Don't follow rigid heuristics — explore organically and note where you experience friction:

Where does understanding one concept require bouncing between many small modules?
Where are modules shallow — interface nearly as complex as the implementation?
Where have pure functions been extracted just for testability, but the real bugs hide in how they're called?
Where do tightly-coupled modules leak across their seams?
Which parts of the codebase are untested, or hard to test through their current interface?

Apply the deletion test to anything you suspect is shallow.

2. Module Depth score

For each candidate module, assign a Module Depth score (1–5, Ousterhout):

Score	Meaning
1	Shallow — interface complexity ≈ implementation
3	Balanced
5	Deep — small interface, substantial hidden behavior

Include the score in each candidate row. Prioritize score ≤ 2 for deepening.

3. Present candidates

Present a numbered list of deepening opportunities. For each candidate:

Files — which files/modules are involved
Problem — why the current architecture is causing friction
Solution — plain English description of what would change
Benefits — explained in terms of locality and leverage, and how tests would improve

Use specs/tech-architecture/tech-stack.md vocabulary for the domain, and LANGUAGE.md vocabulary for the architecture.

ADR conflicts: if a candidate contradicts an existing ADR, only surface it when the friction is real enough to warrant revisiting the ADR. Mark it clearly. Don't list every theoretical refactor an ADR forbids.

Do NOT propose interfaces yet. Ask the user: "Which of these would you like to explore?"

4. Grilling loop

Once the user picks a candidate, drop into a grilling conversation. Walk the design tree with them — constraints, dependencies, the shape of the deepened module, what sits behind the seam, what tests survive.

Side effects happen inline as decisions crystallize:

Naming a deepened module after a concept not in specs/tech-architecture/tech-stack.md? Add the term to specs/tech-architecture/tech-stack.md — same discipline as model-domain (see CONTEXT-FORMAT.md). Create the file lazily if it doesn't exist.
Sharpening a fuzzy term during the conversation? Update specs/tech-architecture/tech-stack.md right there.
User rejects the candidate with a load-bearing reason? Offer an ADR, framed as: "Want me to record this as an ADR so future architecture reviews don't re-suggest it?" Only offer when the reason would actually be needed by a future explorer. See ADR-FORMAT.md.
Want to explore alternative interfaces for the deepened module? See INTERFACE-DESIGN.md.

5. Import-boundary hygiene (e45s14)

When a deepening move splits or merges modules, update specs/import-boundaries.json (Playwright DEPS.list pattern) — declare which scripts/lib/*.sh files may source which peers. CI enforces via:

bash scripts/check-import-boundaries.sh

Run the check before proposing cross-module source edges. Convention docs alone do not authorize new imports; the allowlist must list them.

Verify

→ verify: test -f specs/import-boundaries.json && bash scripts/check-import-boundaries.sh

Deepening

How to deepen a cluster of shallow modules safely, given its dependencies. Assumes the vocabulary in LANGUAGE.md — module, interface, seam, adapter.

Dependency categories

When assessing a candidate for deepening, classify its dependencies. The category determines how the deepened module is tested across its seam.

1. In-process

Pure computation, in-memory state, no I/O. Always deepenable — merge the modules and test through the new interface directly. No adapter needed.

2. Local-substitutable

Dependencies that have local test stand-ins (PGLite for Postgres, in-memory filesystem). Deepenable if the stand-in exists. The deepened module is tested with the stand-in running in the test suite. The seam is internal; no port at the module's external interface.

3. Remote but owned (Ports & Adapters)

Your own services across a network boundary (microservices, internal APIs). Define a port (interface) at the seam. The deep module owns the logic; the transport is injected as an adapter. Tests use an in-memory adapter. Production uses an HTTP/gRPC/queue adapter.

Recommendation shape: "Define a port at the seam, implement an HTTP adapter for production and an in-memory adapter for testing, so the logic sits in one deep module even though it's deployed across a network."

4. True external (Mock)

Third-party services (Stripe, Twilio, etc.) you don't control. The deepened module takes the external dependency as an injected port; tests provide a mock adapter.

Seam discipline

One adapter means a hypothetical seam. Two adapters means a real one. Don't introduce a port unless at least two adapters are justified (typically production + test). A single-adapter seam is just indirection.
Internal seams vs external seams. A deep module can have internal seams (private to its implementation, used by its own tests) as well as the external seam at its interface. Don't expose internal seams through the interface just because tests use them.

Testing strategy: replace, don't layer

Old unit tests on shallow modules become waste once tests at the deepened module's interface exist — delete them.
Write new tests at the deepened module's interface. The interface is the test surface.
Tests assert on observable outcomes through the interface, not internal state.
Tests should survive internal refactors — they describe behaviour, not implementation. If a test has to change when the implementation changes, it's testing past the interface.

Interface Design

When the user wants to explore alternative interfaces for a chosen deepening candidate, use this parallel sub-agent pattern. Based on "Design It Twice" (Ousterhout) — your first idea is unlikely to be the best.

Uses the vocabulary in LANGUAGE.md — module, interface, seam, adapter, leverage.

Process

1. Frame the problem space

Before spawning sub-agents, write a user-facing explanation of the problem space for the chosen candidate:

The constraints any new interface would need to satisfy
The dependencies it would rely on, and which category they fall into (see DEEPENING.md)
A rough illustrative code sketch to ground the constraints — not a proposal, just a way to make the constraints concrete

Show this to the user, then immediately proceed to Step 2. The user reads and thinks while the sub-agents work in parallel.

2. Spawn sub-agents

Spawn 3+ sub-agents in parallel using the Agent tool. Each must produce a radically different interface for the deepened module.

Prompt each sub-agent with a separate technical brief (file paths, coupling details, dependency category from DEEPENING.md, what sits behind the seam). The brief is independent of the user-facing problem-space explanation in Step 1. Give each agent a different design constraint:

Agent 1: "Minimize the interface — aim for 1–3 entry points max. Maximise leverage per entry point."
Agent 2: "Maximise flexibility — support many use cases and extension."
Agent 3: "Optimise for the most common caller — make the default case trivial."
Agent 4 (if applicable): "Design around ports & adapters for cross-seam dependencies."

Include both LANGUAGE.md vocabulary and CONTEXT.md vocabulary in the brief so each sub-agent names things consistently with the architecture language and the project's domain language.

Each sub-agent outputs:

Interface (types, methods, params — plus invariants, ordering, error modes)
Usage example showing how callers use it
What the implementation hides behind the seam
Dependency strategy and adapters (see DEEPENING.md)
Trade-offs — where leverage is high, where it's thin

3. Present and compare

Present designs sequentially so the user can absorb each one, then compare them in prose. Contrast by depth (leverage at the interface), locality (where change concentrates), and seam placement.

After comparing, give your own recommendation: which design you think is strongest and why. If elemen

# Deepen Architecture

Surface architectural friction and propose **deepening opportunities** — refactors that turn shallow modules into deep ones. The aim is testability and AI-navigability.

**Distinct from `define-language` and `model-domain`:** Use this skill to find module-level refactoring opportunities in the codebase. Use `define-language` to produce a canonical glossary of terms. Use `model-domain` to stress-test a plan through a domain-model interview.

## Glossary

Use these terms exactly in every suggestion. Consistent language is the point — don't drift into "component," "service," "API," or "boundary." Full definitions in [LANGUAGE.md](LANGUAGE.md).

- **Module** — anything with an interface and an implementation (function, class, package, slice).

This skill is _informed_ by the project's domain model — `specs/tech-architecture/tech-stack.md` and any `specs/adr/`. The domain language gives names to good seams; ADRs record decisions the skill should not re-litigate. See [CONTEXT-FORMAT.md](../model-domain/CONTEXT-FORMAT.md) and [ADR-FORMAT.md](../model-domain/ADR-FORMAT.md).

## Process

### 1. Explore

Read existing documentation first:

- `specs/tech-architecture/tech-stack.md` (or `specs/tech-architecture/tech-stack.md` + each `specs/tech-architecture/tech-stack.md` in a multi-context repo)

- Which parts of the codebase are untested, or hard to test through their current interface?

Apply the **deletion test** to anything you suspect is shallow.

### 2. Module Depth score

For each candidate module, assign a **Module Depth score** (1–5, Ousterhout):

| Score | Meaning |
|-------|---------|
| 1 | Shallow — interface complexity ≈ implementation |
| 3 | Balanced |
| 5 | Deep — small interface, substantial hidden behavior |

Include the score in each candidate row. Prioritize score ≤ 2 for deepening.

### 3. Present candidates

Present a numbered list of deepening opportunities. For each candidate:

- **Want to explore alternative interfaces for the deepened module?** See [INTERFACE-DESIGN.md](INTERFACE-DESIGN.md).

### 5. Import-boundary hygiene (e45s14)

When a deepening move **splits or merges modules**, update `specs/import-boundaries.json` (Playwright `DEPS.list` pattern) — declare which `scripts/lib/*.sh` files may `source` which peers. CI enforces via:

```bash
bash scripts/check-import-boundaries.sh
