+# Cheap Design Refactoring Opportunities
+
+## Refactoring Complete ✅
+
+This document originally captured Cheap Design refactoring opportunities in the Hubot codebase. All identified opportunities have been successfully implemented through 9 incremental refactors.
+
+## Completed Refactors
+
+1. ✅ **Script loaders** (Robot.mjs): 3 duplicate methods → unified `_loadScript`
+2. ✅ **Adapter loading** (Robot.mjs): Nested if/else → resolver table strategy
+3. ✅ **Catch-all fallback** (Robot.mjs): Recursive `receive()` → in-place message conversion
+4. ✅ **Help parsing** (HelpParser.mjs): Isolated utility module
+5. ✅ **Middleware consolidation** (Middleware.mjs): Added `executeAndAllow()` helper
+6. ✅ **Response method consolidation** (Response.mjs): 6 duplicate methods → registry-driven generation
+7. ✅ **Brain user lookup** (Brain.mjs): 3 similar search methods → unified `_findUsers()` helper with predicates
+8. ✅ **Adapter method consolidation** (Adapter.mjs): Duplicate emote/reply → formatter-based delegation
+9. ✅ **Listener registration** (Robot.mjs): Duplicate message-type listeners → `LISTENER_REGISTRY` and `_registerListener()` helper
+
+---
+
+## Key Principles Applied
+
+All implementations follow Pfeifer's Cheap Design:
+- **Move variation into data**: Method registries, predicate functions, transformer tables
+- **Reduce control branching**: Replace if/else chains with table lookups and strategy patterns
+- **Separate concerns**: Extract helpers, utilities, and formatters into focused modules
+- **Leverage existing platform**: Use Object.entries(), Array.filter(), Map/Object lookups
+- **Maintain backward compatibility**: All public APIs preserved; internal refactors only
+
+## See README.md
+
+For detailed information about each completed refactor, see the "Cheap Design Principle" section in README.md.
+
+
+### 1. Response Method Consolidation ✅ (COMPLETED)
+**Location:** `src/Response.mjs` (lines 23-75)
+
+**Current Pattern:**
+Six nearly-identical methods that differ only in method name and options:
+- `send()` → calls `#runWithMiddleware('send', { plaintext: true }, ...strings)`
+- `emote()` → calls `#runWithMiddleware('emote', { plaintext: true }, ...strings)`
+- `reply()` → calls `#runWithMiddleware('reply', { plaintext: true }, ...strings)`
+- `topic()` → calls `#runWithMiddleware('topic', { plaintext: true }, ...strings)`
+- `play()` → calls `#runWithMiddleware('play', {}, ...strings)`
+- `locked()` → calls `#runWithMiddleware('locked', { plaintext: true }, ...strings)`
+
+**Cheap Design Solution:**
+Create a response method registry/table mapping method names to options:
+```javascript
+const RESPONSE_METHODS = {
+  send: { plaintext: true },
+  emote: { plaintext: true },
+  reply: { plaintext: true },
+  topic: { plaintext: true },
+  play: {},
+  locked: { plaintext: true }
+}
+
+// Single factory that generates methods
+Object.entries(RESPONSE_METHODS).forEach(([methodName, opts]) => {
+  Response.prototype[methodName] = function (...strings) {
+    return this.#runWithMiddleware(methodName, opts, ...strings)
+  }
+})
+```
+
+**Impact:** Removes ~60 lines of duplication; makes adding new response types trivial; clarifies what makes each method unique (just options).
+
+**Feasibility:** HIGH - No external API changes, fully backward compatible.
+
+---
+
+### 2. **Adapter Method Consolidation** (MEDIUM IMPACT)
+**Location:** `src/adapters/Shell.mjs` and `src/adapters/Campfire.mjs`
+
+**Current Pattern:**
+Adapters repeat similar logic across `send()`, `emote()`, `reply()`, etc. Each adapter reimplements the pattern:
+- Shell: Maps emote to `* ${str}`, reply to `${name}: ${str}`
+- Campfire: Same mapping pattern with different transport
+
+**Cheap Design Solution:**
+Create a base adapter method map that child adapters can override:
+```javascript
+class Adapter {
+  // Method transformations (data)
+  #methodTransforms = {
+    emote: (str) => `*${str}*`,
+    reply: (str, envelope) => `${envelope.user.name}: ${str}`
+  }
+
+  // Generic send implementation that child adapters extend
+  async _sendWithTransform(methodName, envelope, ...strings) {
+    const transform = this.#methodTransforms[methodName]
+    const transformed = transform ? strings.map(s => transform(s, envelope)) : strings
+    return await this.send(envelope, ...transformed)
+  }
+}
+```
+
+**Impact:** Reduces duplication across adapter implementations; standardizes method mapping.
+
+**Feasibility:** MEDIUM - Requires careful inheritance design to avoid breaking adapters.
+
+---
+
+### 3. **Brain User Lookup Consolidation** (MEDIUM IMPACT)
+**Location:** `src/Brain.mjs` (lines 160-200)
+
+**Current Pattern:**
+Multiple user lookup methods with similar filtering/search logic:
+- `userForName(name)` - exact match on name
+- `usersForRawFuzzyName(fuzzyName)` - prefix match
+- `usersForFuzzyName(fuzzyName)` - exact fallback to prefix match
+- Manual loops with similar predicates
+
+**Cheap Design Solution:**
+Create a unified user search function with pluggable predicates:
+```javascript
+_findUsers(predicate) {
+  const users = this.data.users || {}
+  return Object.values(users).filter(user => predicate(user))
+}
+
+userForName(name) {
+  const lowerName = name.toLowerCase()
+  const results = this._findUsers(u => u.name?.toLowerCase() === lowerName)
+  return results[0] ?? null
+}
+
+usersForRawFuzzyName(fuzzyName) {
+  const lowerName = fuzzyName.toLowerCase()
+  return this._findUsers(u => 
+    u.name?.toLowerCase().startsWith(lowerName)
+  )
+}
+
+usersForFuzzyName(fuzzyName) {
+  const exact = this._findUsers(u => 
+    u.name?.toLowerCase() === fuzzyName.toLowerCase()
+  )
+  if (exact.length > 0) return exact
+  return this.usersForRawFuzzyName(fuzzyName)
+}
+```
+
+**Impact:** Removes loop duplication; clarifies search logic; makes predicates reusable.
+
+**Feasibility:** HIGH - Internal refactor, no API changes.
+
+---
+
+### 4. **Router Method Registration** (LOW-MEDIUM IMPACT)
+**Location:** `src/Robot.mjs` - HTTP router methods
+
+**Current Pattern:**
+Public API methods like `hear()`, `respond()`, `enter()`, `leave()`, `topic()` all:
+1. Accept similar parameter patterns (regex/matcher, options, callback)
+2. Normalize optional parameters
+3. Create appropriate listener type
+4. Push to `this.listeners`
+
+**Cheap Design Solution:**
+Create a listener registration registry:
+```javascript
+const LISTENER_TYPES = {
+  hear: TextListener,
+  respond: (regex, options, callback) => {
+    const pattern = this.respondPattern(regex)
+    return new TextListener(this, pattern, options, callback)
+  },
+  enter: { matcher: msg => msg instanceof Message.EnterMessage },
+  leave: { matcher: msg => msg instanceof Message.LeaveMessage },
+  topic: { matcher: msg => msg instanceof Message.TopicMessage }
+}
+
+#registerListener(type, arg1, arg2, arg3) {
+  // Normalize args
+  const [matcher, options, callback] = this._normalizeListenerArgs(arg1, arg2, arg3)
+  const config = LISTENER_TYPES[type]
+  const listener = new (config.listenerClass || Listener)(this, matcher, options, callback)
+  this.listeners.push(listener)
+}
+```
+
+**Impact:** Reduces method duplication; makes pattern clearer; easier to add new listener types.
+
+**Feasibility:** MEDIUM - Requires refactoring multiple public API methods.
+
+---
+
+## Recommended Next Steps
+
+1. **Start with Response Method Consolidation** (HIGH priority, quickest win)
+   - Highest impact-to-complexity ratio
+   - Fully isolated in Response.mjs
+   - 60 lines of clear duplication
+   - Fully backward compatible
+
+2. **Then Brain User Lookup** (HIGH priority, good impact)
+   - Clean internal refactor
+   - Clarifies search predicates
+   - No API changes needed
+
+3. **Optional: Adapter Method Consolidation** (if time permits)
+   - Requires coordination across adapter files
+   - More complex inheritance changes
+   - Good long-term architectural improvement
+

 In most cases, you'll probably never have to hack on this repo directly if you
 are building your own bot. But if you do, check out [CONTRIBUTING.md](CONTRIBUTING.md)
 
+## Cheap Design Principle
+
+This codebase is being incrementally refactored using Pfeifer's Cheap Design idea: simplify control by leveraging structure and existing platform capabilities. Rather than maintaining multiple near-duplicate code paths, we consolidate them and let data (like file extensions or loader state) drive behavior.
+
+### Script Loading (Applied)
+Replaced three largely similar loaders (`loadjs`, `loadmjs`, `loadts`) in `src/Robot.mjs` with a single internal `_loadScript` function invoked by thin wrappers:
+- Reduced branching: one import path, fewer error surface areas
+- Clearer warnings: unified message when default export is not a function
+- Easier extension: new script types map to the same loader
+
+### Adapter Loading (Applied)
+Eliminated nested if/else branching in `loadAdapter` by introducing a **resolver table** in `_selectAdapterResolver`. Each adapter loading strategy (built-in, local file, npm package) is now a simple, isolated resolver function:
+- **Data-driven dispatch**: Resolver selection based on adapter state and path extension, not control flow
+- **Separated concerns**: Each resolver (`_loadBuiltinAdapter`, `_loadLocalAdapter`, `_loadNpmAdapter`) has one responsibility
+- **Extensible pattern**: Adding a new adapter type requires only a new resolver and condition, no new if/else chains
+
+### Catch-All Listener Fallback (Applied)
+Eliminated recursive fallback logic in `processListeners` by replacing it with simple in-place message conversion:
+- **No recursion**: Instead of calling `receive()` recursively, convert the original message to `CatchAllMessage` and re-process the same listener loop
+- **Uniform dispatch**: Catch-all listeners now compete equally with all listeners—they just match only on `CatchAllMessage` types
+- **Cleaner control flow**: The fallback is now just data transformation, not special-case control logic
+
+### Help Parsing Extraction (Applied)
+Extracted help documentation parsing logic from `Robot.mjs` into a dedicated `src/HelpParser.mjs` utility module:
+- **Single responsibility**: `HelpParser` handles all comment extraction and section parsing; `Robot` just collects commands
+- **Reduced coupling**: Robot no longer needs to know about comment markers, header blocks, or legacy syntax detection
+- **Testable in isolation**: Help parsing logic can be tested independently without creating a Robot instance
+- **Removed 4 helper functions**: `toHeaderCommentBlock`, `isCommentLine`, `removeCommentPrefix`, and parsing logic are now in the utility
+
+### Middleware Consolidation (Applied)
+Added `executeAndAllow()` helper method to `Middleware` class to standardize the common "execute and check for false" pattern:
+- **Reduced boilerplate**: `Robot.receive()` and `Response.#runWithMiddleware()` now use `executeAndAllow()` instead of `execute()` + conditional check
+- **Clearer intent**: The method name expresses the actual operation: "execute middleware and allow if it doesn't forbid"
+- **Consistent semantics**: All middleware checks now use the same idiomatic pattern across Robot, Response, and Listener
+
+### Response Method Consolidation (Applied)
+Eliminated six nearly-identical response methods (`send`, `emote`, `reply`, `topic`, `play`, `locked`) from `src/Response.mjs`:
+- **Method registry**: All methods now defined in `RESPONSE_METHODS` object mapping method names to their options (e.g., `plaintext: true`)
+- **Dynamic generation**: Methods are generated once at module load via `Object.entries()` and prototype assignment—no code duplication
+- **Easy extension**: Adding a new response type requires only adding an entry to the registry, not writing a full method
+- **Reduced lines**: Eliminated 60+ lines of boilerplate; core logic is now just the `_runWithMiddleware` helper
+
+### Brain User Lookup Consolidation (Applied)
+Unified three similar user search methods in `src/Brain.mjs` using a single internal `_findUsers()` helper with pluggable predicates:
+- **Unified search logic**: `userForName`, `usersForRawFuzzyName`, and `usersForFuzzyName` all call `_findUsers` with different predicates
+- **Pluggable predicates**: Each predicate function encapsulates its specific matching logic (exact, prefix, etc.) independently
+- **Single return pattern**: Helper manages both single-result and array-result cases via `returnSingle` parameter
+- **Eliminated duplication**: Removed manual loops, reducing code size while keeping all public APIs identical
+
+### Adapter Method Consolidation (Applied)
+Eliminated near-duplicate `emote()` and `reply()` methods from Shell and Campfire adapters by introducing `_createSendDelegate()` in the base Adapter class:
+- **Formatter-based consolidation**: Each adapter defines formatters (e.g., `#emoteFormatter`, `#replyFormatter`) that transform strings before sending
+- **Reusable helper**: `_createSendDelegate(formatter)` returns an async function that applies the formatter to all strings, then calls `send()`
+- **Reduced adapter code**: Shell and Campfire now use one-liners: `emote = this._createSendDelegate(this.#emoteFormatter)`
+- **Extensible pattern**: New adapters can reuse the helper for any string-transformation-then-send pattern
+
+### Listener Registration Consolidation (Applied)
+Eliminated near-duplicate message-type listener registration methods (`enter`, `leave`, `topic`) in `src/Robot.mjs` using a static registry and helper:
+- **Registry-driven dispatch**: `LISTENER_REGISTRY` maps message type keys (e.g., 'enter') to their predicate functions
+- **Unified registration helper**: `_registerListener(registryKey, options, callback)` looks up the predicate and delegates to `listen()`
+- **Reduced boilerplate**: Each method (`enter`, `leave`, `topic`) now a one-liner calling `_registerListener` with its registry key
+- **Extensible design**: Adding a new message-type listener requires only adding an entry to the registry, not a full new method
+- **Clear separation**: Message types and predicates live in the registry; registration logic is isolated in the helper
