Supersedes #356

This PR supersedes #356. GitHub does not allow renaming the source branch of a cross-fork pull request, so the reviewed implementation continues here on the compliant branch.

What this changes

Closes #218.

This adds workspace-scoped instructions for Orbit MCP clients:

  • Stores up to 4,000 characters on the organization with an empty default
  • Lets workspace administrators edit the instructions through the existing org:manage policy
  • Includes current guidance during MCP initialization when the connection has orbit.read
  • Adds the read-only get_workspace_instructions refresh tool
  • Preserves workspace membership, OAuth scope, and server policy as the authorization boundary
  • Keeps team-level overrides out of scope

Concurrency behavior

Instruction edits use a compare-and-set against the previous instruction text. A real concurrent instruction edit returns a conflict, while unrelated workspace changes such as a name, logo, or allowed-domain update do not reject a valid instruction save. The update validator also rejects a standalone concurrency field.

Implementation

  • Adds organization.agentInstructions, migration 0015_salty_rocket_raccoon, and the idempotent catch-up path
  • Adds the General settings editor, character counter, dirty-field submission, and conflict handling
  • Adds dynamic MCP initialization context and get_workspace_instructions
  • Adds validator, service, settings, migration, scope, membership, workspace-isolation, refresh, and authorization coverage
  • Updates docs/mcp.md

Validation on daf9ee2b

  • 128 focused tests passed across shared validators, organization service, MCP auth and tools, web settings, and catch-up behavior
  • Full repository typecheck passed
  • Biome lint and repository policy checks passed
  • A blank database migrated through 0015, and schema drift validation passed
  • The unchanged chart file passed 16 of 16 tests when run with the web package DOM preload
  • bun run verify completed static checks and extensive package suites, then local Bun 1.3.14 exited with SIGTRAP upon entering that unchanged chart file
  • The pre-push lint and typecheck hook passed
  • git diff --check passed

Checklist

  • Tests added for the feature and its repaired concurrency behavior
  • No comments added to shipped code
  • No em dash characters
  • Strict types preserved
  • External input parsed with shared Zod schemas
  • Authorization enforced through the server policy layer
  • Documentation updated
  • Migration release and drift paths validated

Workspace instructions are advisory. They never replace policy checks or OAuth scopes.

Greptile Summary

This PR adds workspace-scoped agent instructions for MCP clients, including administrator editing, validated persistence, initialization context, and an explicit refresh tool.

  • Adds the organization field, migration, idempotent catch-up path, and validation.
  • Adds a settings editor that submits only edited fields and uses instruction-specific optimistic concurrency.
  • Exposes instructions to read-scoped MCP clients during initialization and through a read-only tool.
  • Adds authorization, isolation, migration, validation, concurrency, and UI coverage.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains; the previous shared-version rejection is resolved by comparing only the instruction baseline, so unrelated workspace updates no longer reject an instruction save.

Important Files Changed

Filename Overview
apps/web/src/features/settings/general-form.tsx Adds the instruction editor, dirty-field payload construction, baseline tracking, and conflict-safe submission behavior.

Thanks for your first pull request to Orbit.

Two things that will save you a review round: bun run verify runs the
same four checks CI does, and the repo has no comments in code by policy,
so bun run check-comments will flag any you added out of habit.

A maintainer will review this shortly. Ask anything on the thread.

📝 Walkthrough

Walkthrough

The change stores workspace agent instructions, exposes them in general settings, validates and updates them with optimistic concurrency, and serves them through MCP initialization and a read-only refresh tool.

Changes

Workspace agent instructions

Layer / File(s) Summary
Instruction storage and validation
packages/shared/src/constants/organization.ts, packages/shared/src/validators/organization.ts, packages/db/src/schema/org.ts, packages/db/drizzle/..., packages/db/catchup/..., packages/db/tests/apply-catchup.test.ts, packages/shared/tests/validators/validators.test.ts
The organization schema stores non-null agentInstructions with an empty-string default. Migrations backfill existing rows and support repeated catchup application. Shared validation limits instructions to 4,000 characters and requires an instruction update when an expected baseline is supplied.
Organization updates and concurrency
packages/core/src/org/organization-service.ts, packages/core/tests/org/organization-service.test.ts
Organization updates include defined instruction fields. Instruction updates can compare expectedAgentInstructions and return stale_workspace_instructions conflicts. Tests cover permissions, persistence, stale baselines, compatibility, defaults, and length limits.
Settings editor and dirty-field saves
apps/web/src/app/(app)/settings/general/page.tsx, apps/web/src/features/settings/general-form.tsx, apps/web/tests/app/settings/general/page.test.tsx, apps/web/tests/features/settings/general-form.test.tsx
General settings now edit agent instructions with a 4,000-character counter. The form tracks per-field dirty state, sends only changed fields, and uses the instruction text as the concurrency baseline. Tests cover rendering, saving, stale tabs, boundaries, and conflicts.
MCP instruction delivery and refresh
packages/mcp-server/src/server.ts, packages/mcp-server/src/tools/identity.ts, packages/mcp-server/tests/auth.test.ts, packages/mcp-server/tests/tools.test.ts, docs/mcp.md
Read-scoped initialization loads workspace instructions into the MCP server. The get_workspace_instructions tool returns current instructions to eligible members. Tests cover scope checks, membership, initialization batches, workspace isolation, snapshots, refreshes, discovery, and 4,000-character content. Documentation describes the permission model and advisory behavior.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: ⚪ Minimal · up to daf9e

111-117: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Use a TanStack Query mutation for the workspace PATCH.

GeneralForm receives organization settings as server-rendered props. The query setup hydrates only bootstrap and issue data, and defines no current-organization cache. Move the apiRequest call into useMutation, then keep router.refresh() for the updated server-rendered settings. Do not add rollback logic for a cache that does not exist.

Thanks for redoing this from a compliant branch, and for working through all six #356 findings inline (locale-safe counter, the orbit.read doc note, settings regression coverage, the shared Textarea component, dirty-field/sync-id saves, and initialize-only instruction loading).

Flagging one thing ahead of a full pass: Greptile's finding on organization-service.ts:162-165 looks real to me. expectedSyncId is the whole-organization syncId, so an unrelated name/logo/domain edit racing an instructions save will bounce as stale even though the instructions themselves didn't change. Worth deciding whether that narrow window is acceptable or whether the concurrency check should scope to the instructions field specifically, before I look at the rest.

Marking needs-review and queuing this up.
