Summary

• Superset chat: anthropic/claude-sonnet-5-5
• Claude Code: claude-sonnet-5-5 under Pinned releases (the sonnet alias already tracks newest)
• Copilot: claude-sonnet-5.5 (dotted id, per models.dev github-copilot)
• OpenCode / OMP: anthropic/claude-sonnet-5-5 (models.dev anthropic)
• Slack bot: added to SLACK_MODELS and the adaptive-thinking list; default stays Sonnet 5

Not changed:

• Cursor: cursor-agent --list-models on our account exposes no Sonnet ids and models.dev has no Cursor entry, so there is no verified effort-variant id to add.
• Usage pricing: claude-sonnet-5-5 already prefix-matches the Sonnet 5 rate ($2/$10), which is Sonnet 5.5's price.
• Sonnet 5.5 rejects thinking: disabled and forced tool_choice; neither the chat runtime nor the Slack agent sends them.

Validation

• bun test packages/shared agent-models.test.ts (86 pass) and apps/api Slack tests (124 pass)
• tsc --noEmit on packages/shared
• Not verified: a live Sonnet 5.5 session through any agent or Superset chat.

Summary by cubic

Adds Claude Sonnet 5.5 to the model pickers for Superset chat, Claude Code, Copilot, OpenCode, and OMP, and to the Slack bot's model list with adaptive thinking.

Notes

• Cursor is not added because its live catalog exposed no Sonnet 5.5 id to verify.
• Sonnet 5.5 pricing already matches Sonnet 5 via prefix, and the runtimes don't send options Sonnet 5.5 rejects.

^{Written for commit 3b989ea. Summary will update on new commits.}

📝 Walkthrough

Walkthrough

Claude Sonnet 5.5 was added to the shared chat and agent model catalogs. The Slack integration now lists the model and includes it among the models configured for adaptive thinking. Tests were updated to cover the catalog entries.

Changes

Claude Sonnet 5.5 support

Layer / File(s)	Summary
Shared model catalogs and tests packages/shared/src/agent-models.ts, packages/shared/src/agent-models.test.ts	Added Sonnet 5.5 to the Superset chat, Claude, Copilot, OpenCode, and OMP catalogs. Updated launch and cloud chat catalog assertions.
Slack model support apps/api/src/app/api/integrations/slack/constants.ts, apps/api/src/app/api/integrations/slack/events/utils/run-agent/run-agent.ts	Added Sonnet 5.5 to Slack’s model options and adaptive thinking model list.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Feature

Suggested reviewers: avipeltz

Merge Risk: ⚪ Minimal · up to 3b989

Slack’s Sonnet 5.5 option receives adaptive thinking, and a direct test would protect that behavior. OpenCode and OMP recognition remain unconfirmed rather than shown broken, so no concrete merge-blocking failure is established.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 3b989

The new selectable option does not appear to grant additional access or change the default. Its live behavior has not been verified, leaving some compatibility uncertainty.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — A linked Slack user can select the new option for their scoped stored preference; subsequent requests use the existing service credential and curated tools. No additional tenant or tool authority is evidenced from the model choice.

Trust Boundaries and Controls

• observed — The interaction endpoint verifies the Slack signature before processing a selection, resolves its workspace connection, and looks up the linked identity by organization, Slack user, and team before updating it.

Resilience and Maintainability Implications

• observed — The interaction writer does not check a selected value against the picker list before persisting it. That condition and the inconsistent handling of unknown preferences predate this PR; the new first option changes the displayed fallback, not the request's handling of an unknown value.

Hardening Proposals

• proposed — Validate persisted selections against the supported Slack choices and resolve unknown preferences to one effective value for both display and execution. This would harden a pre-existing boundary, not address a verified new exploit.

Add direct coverage for Sonnet 5.5 adaptive thinking.

The existing test covers claude-sonnet-5, not claude-sonnet-5-5. Removing the new model ID would leave the relevant tests unchanged. Add a test that passes Sonnet 5.5 and asserts adaptive thinking.

Suggested fix

 	test("uses Sonnet 5 with thinking, caching and curated tools", async () => {
 		await runSlackAgent(params);
 		expect(create.mock.calls[0]?.[0]).toMatchObject({
 			model: "claude-sonnet-5",
 			thinking: { type: "adaptive" },
@@
 		expect(cleanup).toHaveBeenCalledTimes(1);
 	});
+	test("uses Sonnet 5.5 with adaptive thinking", async () => {
+		await runSlackAgent({ ...params, model: "claude-sonnet-5-5" });
+		expect(create.mock.calls[0]?.[0]).toMatchObject({
+			model: "claude-sonnet-5-5",
+			thinking: { type: "adaptive" },
