feat: drop shared_context — use memory v2 team namespace instead
Parent → child knowledge sharing previously lived behind a `shared_context` list in config.yaml: at boot, every child workspace HTTP-fetched its parent's listed files via GET /workspaces/:id/shared-context and prepended them as a "## Parent Context" block. That paid the full transfer cost on every boot regardless of whether the agent needed it, single-parent SPOF, no team or org scope, and broken if the parent was unreachable. Replace with memory v2's team:<id> namespace: agents call recall_memory on demand. For large blob-shaped artefacts see RFC #2789 (platform-owned shared file storage). Removed: - workspace/coordinator.py: get_parent_context() - workspace/prompt.py: parent_context arg + injection block - workspace/adapter_base.py: import + call + arg pass - workspace/config.py: shared_context field + parser entry - workspace-server/internal/handlers/templates.go: SharedContext handler - workspace-server/internal/router/router.go: GET /shared-context route - canvas/src/components/tabs/ConfigTab.tsx: Shared Context tag input - canvas/src/components/tabs/config/form-inputs.tsx: schema field + default - canvas/src/components/tabs/config/yaml-utils.ts: serializer entry - 6 tests pinning the removed behavior; 5 doc references Added regression gates so any reintroduction is loud: - workspace/tests/test_prompt.py: build_system_prompt must NOT emit "## Parent Context" - workspace/tests/test_config.py: legacy YAML key loads cleanly but shared_context attr must NOT exist on WorkspaceConfig - tests/e2e/test_staging_full_saas.sh §9d: GET /shared-context must NOT return 200 against a live tenant Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |

feat(prompt): Platform Capabilities preamble at top of system prompt
Closes #2332 item 1 (workspace awareness — agents don't surface platform-native tools up front). The dogfooding session surfaced that agents weren't using A2A delegation, persistent memory, or send_message_to_user. The tools were registered AND documented in the system prompt — but only in sections #8 (Inter-Agent Communication) and #9 (Hierarchical Memory), which agents read AFTER they've already started reasoning about a plan from earlier sections. This adds a tight inventory at section #1.5 (immediately after Platform Instructions, before role-specific prompt files) — every tool name + its short description in a bulleted block. Detailed when_to_use docs in sections #8/#9 stay; this preamble is the elevator pitch ("you have these"), the later sections are the manual ("here's when and how"). Generated from `platform_tools.registry` ToolSpecs — every tool's `name` + `short` flow through automatically, no manual sync. A new `get_capabilities_preamble(mcp: bool)` helper in executor_helpers mirrors the existing get_a2a_instructions / get_hma_instructions pattern. CLI-runtime agents (mcp=False) get an empty preamble — they see _A2A_INSTRUCTIONS_CLI's hand-written subcommand vocabulary further down, and the registry's MCP tool names would conflict. Tests: - test_capabilities_preamble_appears_in_mcp_prompt: header present - test_capabilities_preamble_lists_every_registry_tool: every a2a + memory tool from registry shows up (drift catches at test time — adding a new tool to registry surfaces here automatically) - test_capabilities_preamble_precedes_prompt_files: ordering invariant (toolkit before role docs) - test_capabilities_preamble_skipped_for_cli_runtime: empty when mcp=False All 40 prompt + platform_tools tests pass. |

feat(platform): single-source-of-truth tool registry — adapters consume, no drift
Establishes workspace/platform_tools/registry.py as THE place tool
naming and docs live. Every consumer reads from it; nothing duplicates
the source. Closes the architectural gap behind the doc/tool drift
discussion 2026-04-28 — adding hundreds of future runtime SDK adapters
should not require touching tool names anywhere except the registry.
What the registry owns
ToolSpec dataclass with: name, short (one-line description), when_to_use
(multi-paragraph agent-facing usage guidance), input_schema (JSON Schema),
impl (the actual coroutine in a2a_tools.py), section ('a2a' | 'memory').
TOOLS list with 8 entries — delegate_task, delegate_task_async,
check_task_status, list_peers, get_workspace_info, send_message_to_user,
commit_memory, recall_memory.
What now reads from the registry
- workspace/a2a_mcp_server.py
The hardcoded TOOLS list (167 lines of hand-maintained dicts) is
gone. Replaced with a 6-line list comprehension over the registry.
MCP description = spec.short. inputSchema = spec.input_schema.
- workspace/executor_helpers.py
get_a2a_instructions(mcp=True) and get_hma_instructions() now
GENERATE the agent-facing system-prompt text from the registry.
Heading + per-tool bullet (spec.short) + per-tool when_to_use +
a section-specific footer. No more hand-maintained instruction
blocks that drift from reality.
- workspace/builtin_tools/delegation.py
Renamed delegate_to_workspace -> delegate_task_async to match
registry. check_delegation_status -> check_task_status. Added
sync delegate_task @tool wrapping a2a_tools.tool_delegate_task
(was missing for LangChain runtimes — CP review Issue 3).
- workspace/builtin_tools/memory.py
Renamed search_memory -> recall_memory to match registry.
- workspace/adapter_base.py, workspace/main.py
Bundle all 7 core tools (was 6) into all_tools / base_tools.
- workspace/coordinator.py, shared_runtime.py, policies/routing.py
Updated system-prompt-text references to use the registry names.
Structural alignment tests
workspace/tests/test_platform_tools.py — 9 tests pin every
registry-to-adapter mapping:
- registry names are unique
- a2a + memory partition is complete (no orphans)
- by_name lookup works
- MCP server registers exactly the registry's tool set
- MCP description equals registry.short for every tool
- MCP inputSchema equals registry.input_schema for every tool
- get_a2a_instructions text contains every a2a tool name
- get_hma_instructions text contains every memory tool name
- pre-rename names (delegate_to_workspace, search_memory,
check_delegation_status) cannot leak back
Adding a future tool means adding one ToolSpec; the test failure
list tells the author exactly which adapter to update.
Adapter pattern for future SDK support
When (e.g.) AutoGen or Pydantic AI gets adapters, the only work
needed for tool surfacing is "wrap registry.TOOLS in your SDK's
tool format." Names, descriptions, schemas, impl come from the
registry — adapter author writes zero strings.
Why this needed to ship now
PR #2237 (already in staging) injected MCP-world docs as the
default system-prompt content. Without the registry, those docs
said "delegate_task" while LangChain runtimes only had
"delegate_to_workspace" — workers see docs for tools that don't
exist (CP review Issue 1+3). PR #2239 was a tactical rename;
this PR is the structural fix that prevents the same class of
drift from recurring as new adapters ship.
PR #2239 was closed in favor of this — same renames, plus the
registry, plus structural tests. Single coherent change.
Tests: 1232 pass, 2 xfailed (pre-existing). 9 new in
test_platform_tools.py; 4 alignment tests in test_prompt.py from
#2237 still pass; original test_executor_helpers tests adapted to
the registry-driven world.
Refs: CP review Issues 1, 2, 3, 5; project memory
project_runtime_native_pluggable.md (platform owns A2A);
project memory feedback_doc_tool_alignment.md (this is the structural
fix for the tactical lesson).

fix(prompt): inject A2A and HMA tool instructions into system prompt
Workers were registering platform tools (delegate_task, delegate_task_async, list_peers, check_task_status, send_message_to_user, commit_memory, recall_memory) but the build_system_prompt assembly never included documentation for any of them. The instruction-text functions get_a2a_instructions() and get_hma_instructions() exist in executor_helpers.py and have unit tests, but were not called from any production code path — workers received system-prompt.md content only and saw the tools as bare names with no usage guidance. Symptom: agents called commit_memory and delegate_task without knowing they were platform tools. They worked when the agent guessed the API correctly and silently failed when the agent didn't. Fix: build_system_prompt() now appends both instruction sets between the Skills section and the Peers section. The placement is intentional — A2A docs explain how to call delegate_task; the peer list is the data that delegate_task operates over, so the docs precede the peer table. New parameter `a2a_mcp: bool = True` lets adapters opt into the CLI subprocess variant of the A2A instructions for runtimes without MCP support (ollama, custom CLI runtimes). Default True covers the MCP-capable majority (claude-code, hermes, langchain, crewai). Adapter callers don't need to change unless they specifically need CLI mode. Tests: 4 new regression tests in test_prompt.py pin - A2A MCP variant injection (default) - A2A CLI variant injection (a2a_mcp=False, with MCP-only fields absent) - HMA instruction injection - A2A docs precede peer list ordering Full suite green: 1223 passed, 2 xfailed. |

test: update test_peer_capabilities_format for fallback behavior
The previous assertion `'Silent Agent' not in result` was pinning the buggy behavior — peers without an agent_card were silently dropped from the prompt. With the fallback to DB name+role those peers are correctly visible. Flip the assertion so the test pins the new (correct) rendering and would catch a regression to the silent-drop behavior. |
