Enhanced Specification

Implementation Specification: SLAC-10 — Add "clear" as an Alias for the "flush" Command

---

Summary

A user has requested that the bot recognize clear as an alternative command name for the existing flush command. When a user types clear in Slack or Discord, the bot should execute the exact same logic as if they had typed flush — clearing the current Sonos queue. This is a purely additive change: no existing behavior is modified, only a new command alias is registered.

---

Acceptance Criteria

• Typing clear in a configured Slack channel executes the same queue-clearing logic as flush
• Typing clear in a configured Discord channel executes the same queue-clearing logic as flush
• The response message returned to the user after clear is identical to the response returned after flush
• The flush command continues to work exactly as before (no regression)
• clear appears in the help text so users can discover it
• If flush requires any role/permission checks, clear enforces the same checks (no privilege bypass via alias)
• A test exists that verifies clear invokes the same handler as flush

---

Technical Approach

The codebase follows a clear pattern for registering commands: logic lives in command-handlers.js and command strings are mapped to handlers in add-handlers.js. Adding an alias requires no new logic — only an additional registration pointing to the existing handler.

Step 1 — Register the alias in add-handlers.js

Locate the line where flush is registered (likely something like):

addHandler('flush', handleFlush);

Immediately below it, add:

addHandler('clear', handleFlush);

Both strings now point to the same handler function. No conditional logic, no wrapper — the handler is shared by reference.

Step 2 — Update help text in templates/help/helpText.txt

Find the existing entry for flush and append the alias so users know both names are valid. Example:

flush (alias: clear) — Clears the current Sonos queue

Or add a separate line if the template format lists each command individually:

clear — Clears the current Sonos queue (alias for flush)

Match the existing formatting style exactly.

Step 3 — Add a test in test/

Create or extend a relevant test file (e.g., test/add-handlers.test.mjs or test/command-handlers.test.mjs) to assert that the clear command resolves to the same handler as flush. Example pattern using the project's Mocha + Chai + Sinon stack:

import { expect } from 'chai';

// Verify both command strings are registered and invoke the same underlying logic
it('should execute the same handler for "clear" as for "flush"', async () => {
  // Arrange: stub the respond callback and any Sonos dependencies
  const respond = sinon.stub();
  // Act: dispatch both commands through the handler registry
  await dispatchCommand('flush', respond);
  await dispatchCommand('clear', respond);
  // Assert: respond was called twice with identical arguments
  expect(respond.firstCall.args).to.deep.equal(respond.secondCall.args);
});

Adapt to the actual test helper/dispatch mechanism used in the existing test suite.

Files Likely Affected

File	Change Required
lib/add-handlers.js	Primary change. Add one line: addHandler('clear', handleFlush) directly after the flush registration
templates/help/helpText.txt	Add clear to the help entry for flush
test/add-handlers.test.mjs (or equivalent)	Add a test asserting clear and flush invoke the same handler

Files that should NOT need changes:

• lib/command-handlers.js — The handleFlush function is reused as-is; no modification needed
• lib/slack.js / lib/discord.js — Command dispatch is generic; no platform-specific changes needed
• config/config.json — No configuration change required
• lib/ai-handler.js — If the AI handler maps natural language to commands, verify it doesn't need clear added as a recognized intent (see Edge Cases)

---

Edge Cases & Risks

1. Permission / role gating
If flush is restricted to certain roles or admin users, confirm that add-handlers.js applies those checks at the registration level (e.g., via a middleware/wrapper passed alongside the handler). If permissions are checked inside handleFlush itself, the alias inherits them automatically and no extra work is needed. Verify this before closing the ticket.

2. AI/NLP command translation (lib/ai-handler.js)
If the AI handler translates natural language into canonical command strings, it may have a hardcoded list of valid commands. Check whether clear needs to be added to that list, or whether the AI should map "clear the queue" → clear (or continue mapping to flush). If the AI maps to flush and flush still works, this is a non-issue.

3. Telemetry / analytics (lib/telemetry.js)
If command names are tracked by string (e.g., posthog.capture({ command: 'flush' })), clear will be tracked as a distinct event. This is acceptable behavior but worth noting — dashboards will show both flush and clear as separate events. No code change needed unless unified tracking is desired (out of scope for this ticket).

4. Help text format consistency
The help template format is unknown without inspecting the file. Ensure the clear entry matches the exact whitespace, delimiter, and ordering conventions of the existing file to avoid rendering issues in Slack/Discord message formatting.

5. Name collision
Verify that clear is not already registered as a command for something else (e.g., clearing search results, clearing votes). A quick grep of add-handlers.js for 'clear' will confirm this before the change is made.

---

Out of Scope

• Renaming flush to clear — flush must remain fully functional; this is an additive alias only
• Deprecating flush — No deprecation warnings, no removal of the original command
• Changing the behavior of flush/clear — Queue-clearing logic is not to be modified
• Adding other aliases — Only clear is requested in this ticket; do not add reset, empty, or any other aliases
• UI changes — No changes to the web setup wizard or admin panel (public/setup/)
• Updating the AI handler to prefer clear over flush — Unless a collision or bug is discovered during implementation, leave AI behavior unchanged

Pull request overview

This PR aims to implement SLAC-10 by adding clear as an alias for the existing admin flush command (queue clear) and adding automated coverage for the alias behavior.

Changes:

• Adds clear as an exported alias of flush in lib/command-handlers.js.
• Introduces a new test suite test/clear-alias.test.mjs intended to validate the alias and help-text discoverability.
• Includes substantial refactors in lib/command-handlers.js (queue display, up-next, queue sizing, volume handling, search handlers, exports).

File	Description
test/clear-alias.test.mjs	Adds SLAC-10-focused tests for a clear alias and help-text checks.
lib/command-handlers.js	Exports clear as an alias for flush, but also significantly refactors queue/volume/search behavior and the module’s public exports.

[Copilot]

clear: flush being exported does not make the bot recognize a clear command: runtime command resolution is done via commandRegistry/aliasMap in index.js. To meet SLAC-10 (and preserve admin-only gating), add clear as an alias for the existing flush command in the command registry (or register a new clear command that points to the same handler with admin: true).

Suggested change

clear: flush, // Alias for flush (SLAC-10)

[Copilot]

This PR renames/removes several exported handlers (countQueue, searchalbum, searchplaylist) and changes the public shape of commandHandlers. index.js (and existing tests) call these exact exports, so this will cause runtime TypeError: commandHandlers.<name> is not a function on startup. Either keep backward-compatible exports (e.g., export countQueue/searchalbum/searchplaylist as aliases) or update all call sites in the same PR; given SLAC-10’s scope, reverting these unrelated API changes is the safest fix.

[Copilot]

setVolume forwards a 0–100 value directly to soundcraft.setVolume(...), but lib/soundcraft-handler.js validates volume as dB in the range -100..0. This means Soundcraft volume setting will always fail (and the change is a behavioral regression from the previous dB conversion). Convert the user’s 0–100 input to the expected dB range before calling soundcraft.setVolume, or update the Soundcraft API to accept percent consistently.

[Copilot]

The changes in this hunk go far beyond adding a clear alias: showQueue is rewritten and removes existing behaviors (vote indicators, gong-ban/immune markers, threading/chunking, and current-track formatting). This is a significant behavioral change and appears unrelated to SLAC-10; it also risks regressing core voting/queue UX. Consider reverting these unrelated refactors (or splitting them into a separate PR with dedicated tests/validation).

[Copilot]

This help-text suite will fail with the current repository state: templates/help/helpText.txt does not contain flush (and therefore won’t contain clear “near” it). Either update the help template to include the admin flush command (with clear alias) or adjust the test to match the actual help format/contents used by the bot.

	let helpText;
	before(function () {
	helpText = readFileSync('templates/help/helpText.txt', 'utf8');

These structural tests assert that commandHandlers.clear exists and is the same function reference as flush, but SLAC-10’s real contract is that user input clear resolves through the bot’s command registry/alias mechanism (and preserves admin: true gating). Consider replacing these with a test that exercises the actual dispatch path (e.g., processInput()/commandRegistry alias resolution) so the test fails if the alias is registered incorrectly or bypasses permissions.

queueSize uses result.items.length to report the queue length. Sonos getQueue() also returns result.total, and items.length may not match the true queue length if the API returns a subset/paged items. Prefer result.total (with a fallback) to avoid under-reporting the queue size.

Suggested change

	const size = result && result.items ? result.items.length : 0;
	const size = result && typeof result.total === 'number'
	? result.total
	: (result && result.items ? result.items.length : 0);
