Subject: [PATCH 01/21] feat(todo): add agent tools for todo lists, remove
 notes_set_done
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Create todo_tools.py with execute_todo_list_lists, execute_todo_add_item,
and execute_todo_set_done. Register in skill_exec.py SKILL_IMPLEMENTATIONS
and skills.py seed data. Remove deprecated execute_notes_set_done from
notes_tools.py (set_done now lives on TodoStore).

Add tests/todo/test_todo_tools.py (17 tests) covering list/add/set_done
with owner-based access control. Remove notes_set_done tests from
tests/notes/test_notes_tools.py (11 remaining tests pass).

Task: 1923 C3 — Notes/Todo split agent tool surface.

Subject: [PATCH 02/21] fix(todo): strip internal fields from list_lists,
 document owner-auth model

Address Kilo bot findings:
- Filter owner_user_id/archived_at/created_at from list_lists response
- Add docstring notes explaining owner-based authorization model and the
  planned agent_name-to-owner binding for when TodoStore gains membership

No CRITICAL findings. 17/17 todo tools, 11/11 notes tools, 18/18 todo routes pass.

Match the skill schema description which advertises only id, title, updated_at.
Using a whitelist (not blacklist) is the safer pattern — new fields added to
the store row won't leak through by default.

Subject: [PATCH 04/21] fix(todo): remove unused agent_name from list_lists and
 set_done, document auth boundary
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove agent_name validation from execute_todo_list_lists and
execute_todo_set_done — the parameter was accepted but never used.
It was injected by skill_exec.py but served no purpose, creating a
false expectation that agent_name participates in authorization.

For execute_todo_add_item, agent_name is still required (used for
attribution and notification skip-guard). Add explicit SECURITY
comments at each owner_user_id check documenting that agent-to-owner
binding awaits agent membership on TodoStore (#1923 follow-up).

The internal field leak in list_lists was already fixed (allowlist
projection at line 39).

Subject: [PATCH 05/21] fix(github): fix SecretsStore mock in
 _build_app_with_app_config to return private key for github-app-private-key
 lookups

The test helper _build_app_with_app_config(token=None) set mock_secrets.get
to return None for ALL keys, causing _get_app_installation_token to fail
when looking up the GitHub App private key. Now it returns the key for
github-app-private-key lookups while keeping PAT behavior unchanged.

Fixes CI failure: test_repo_endpoint_still_uses_app_token (401 vs 200).
All 4 tests using _build_app_with_app_config now pass.

Subject: [PATCH 06/21] fix(todo): bind agent_name to owner_user_id via
 agent_registry

Resolve owner_user_id from the agent registry (get_by_handle) instead of
trusting the caller-supplied value, closing the authorization gap where any
agent knowing a user_id could enumerate, write to, or toggle another user's
todo lists.

- Add _resolve_owner_user_id() helper: looks up agent_name in agent_registry,
  returns the verified user_id when registry is available (production),
  falls back to args-supplied owner_user_id when absent (test compat).
- execute_todo_list_lists: requires agent_name, derives owner from registry.
- execute_todo_add_item: derives owner from registry instead of trusting args.
- execute_todo_set_done: requires agent_name, derives owner from registry.
- New tests: registry enforcement (AsyncMock), unregistered agent rejection,
  fallback without registry. All 21 todo + 11 notes tests pass.

Fixes Kilo WARNINGs on PR #2035 (agent auth bypass).

Subject: [PATCH 07/21] fix(todo): reorder owner check before archived check to
 prevent state leak

Move the owner_user_id gate before the archived_at gate in both
execute_todo_add_item and execute_todo_set_done. Previously a non-owner
caller who guessed a valid list_id could learn whether the list was
archived. Now the owner check runs first, returning a uniform 'access
denied' error for non-owners regardless of archived state.

Subject: [PATCH 08/21] fix(todo): resolve owner for deployed agents via config
 fallback

When agent_registry.get_by_handle misses (deployed agents are never in
the registry), fall back to find_agent(config, agent_name) and use
request.state.user_id (set by local-token auth for the primary user).

Also: revert github_app_private_key mock regression (tests/test_routes_github.py),
drop owner_user_id from todo input_schemas (skills.py), replace notes_set_done
with todo tools in docs, flag notify.py no-op, add internal-field strip assertions
and deployed-agent fallback tests.

jaylfc review fixes for #2035.

- todo_tools.py: Change 'agent not found in registry' to precise message
  covering both missing-agent and missing-user_id cases (CR inline #2035).
- todo_tools.py: Replace raw str(exc) blanket excepts with logged generic
  messages (CR nitpick, BLE001).
- skill_exec.py: Remove try/except wrappers on 3 _skill_todo_* functions
  so unexpected errors propagate to centralized handler (CR nitpick).
- test_todo_tools.py: Remove CodeRabbit nitpick reference from comment.
- test_todo_tools.py: Extend deployed-agent fallback coverage to
  execute_todo_add_item and execute_todo_set_done (4 new tests).

Tests: 27/27 todo tools pass (includes 4 new), 11/11 notes tools pass.

Subject: [PATCH 12/21] fix(skills): migrate orphan skill assignments before
 deleting
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

_remove_orphan_skills previously deleted agent_skills rows for
notes_set_done without migrating them to todo_set_done. Agents that
had completion access via notes_set_done silently lost it after
startup.

Now the method uses an _ORPHAN_REPLACEMENTS dict that maps each
orphaned skill id to its replacement. Before deleting, it copies
agent assignments to the replacement via INSERT OR IGNORE — if the
agent already has the replacement, the existing newer assignment is
preserved; otherwise the legacy assignment is migrated so access is
not lost.

Subject: [PATCH 13/21] refactor(todo): extract _resolve_and_validate_owner
 helper, deduplicate owner resolution

Extract the triplicated owner resolution + validation pattern from
execute_todo_list_lists, execute_todo_add_item, and execute_todo_set_done
into a shared _resolve_and_validate_owner helper. Fixes stale error
messages that referenced 'owner_user_id' (removed from input schemas in
an earlier commit) and now uses tool-specific error text.

Subject: [PATCH 16/21] fix(todo): use authenticated identity for deployed
 agents not in registry
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace the config.agents lookup fallback with direct use of
request.state.user_id when the agent_registry has no row.  Deployed
agents (config-deployed, calling /api/skill-exec/{id}/call) are never
written to agent_registry — only internal driver handles get written.

The agent IS already authenticated (via local-token or session auth
enforced by the middleware), so request.state.user_id is the caller's
identity.  No config.agents check is needed; simpler and more robust.

Closes jaylfc blocker on PR #2035.

Docs-Reviewed: replaces the notes_set_done skill/tool with todo_list_lists /
todo_add_item / todo_set_done (the done concept moves from shared docs to the
Todo store). The agent-facing tool list is documented in
docs/agent-manual/09-os-control.md and docs/taos-agent-manual.md, both updated
in this PR; agent-coordination.md documents the coordination protocol, not the
skill tool catalogue.

Subject: [PATCH 19/21] docs: trim todo-tool prose to fit compiled-manual size
 budget (#2035)

The three todo-tool entries pushed the compiled agent manual to 18139 chars,
over the 18000 limit (test_compiled_size_under_limit). Tighten to terse
one-liners matching the notes entries; full arg schemas live in skills.py.
