   Issue: #213 Notebooks 4/4: agent MCP tools for notebooks (create, edit, run, read outputs, list kernels)
   Thread: thread:delegated-task:command%3Amcp%3Aebdedfb9-30af-46fd-9b17-e188aa75db01%3Adelegate-task%3Anotebooks-208-213-implement-20261028

   Issue #213 is not implemented. The worktree remains clean at commit 4c8582a2589f0f1a1868798fb318ccb1c607e23a on branch issue-213-notebooks-4-4-agent-mcp-tools-for. No commit, push, PR, server, browser session, or external skill edit was made.

   The initial inspection confirmed that NotebookService owns creation, editing, execution, output reads, saving, controls, and leases. It does not currently expose the requested kernel-listing method, so that needs a service seam as well as the MCP toolkit and authorization wiring. I did not reach implementation, tests, provider or scheduled-agent verification, or the headless notebook proof.

   The free baseline context check succeeded:

   cd evals
   PATH=$HOME/.local/share/vite-plus/fallback-bin:$PATH nice -n 10 pnpm mcp-tool-use --context
   

   It reported 7,669 system-text characters, 22,678 tool-description characters, and 66,121 schema characters across 89 tools. A free dry run also succeeded for the existing forgejo-issue-post case, but no notebook case was added or checked. The dry-run invocation triggered a workspace dependency install; the tracked worktree remains clean. Paid evaluation was skipped because no API key exists.

   The external skills checkout was confirmed on main, two commits ahead, with the unrelated changes you identified. Its requested notebook skill update remains outstanding, with no diff or commit from this task. Required package checks, after-change eval measurements, and independent checking remain outstanding.

   I did not implement #213 in this turn. The worktree remains clean at 4c8582a2589f0f1a1868798fb318ccb1c607e23a, and no background work is running.

   I confirmed that MCP client authentication currently constructs an invocation context without filesystem or terminal scopes. That is a boundary the implementation needs to address, but it is not an external blocker. I stopped without delivering the requested changes or validation; the full implementation remains outstanding.

   Issue: #213 Notebooks 4/4: agent MCP tools for notebooks (create, edit, run, read outputs, list kernels)
   Thread: thread:delegated-task:command%3Amcp%3A63f1e9ac-f283-4d26-bfe1-56305e0e0a42%3Adelegate-task%3Anotebooks-208-213-sol-takeover

   Completed: 2026-10-29T17:05:44.449Z

   Implemented and committed locally: ee93f49119cb672b2df071cfc2d7b0756cec2821.

   • Branch: issue-213-notebooks-4-4-agent-mcp-tools-for
   • Worktree: /home/tnnrpolley21/Workspaces/Applications/t3code/.worktrees/issue-213-notebooks-4-4-agent-mcp-tools-for
   • Working tree is clean. No push, PR, merge, or delegation.

   The fork-owned toolkit exposes open, create, edit cells, run, read outputs, list kernels, save, interrupt, restart, and shutdown through NotebookService. It resolves the authenticated thread’s project/workspace, checks live caller identity and runtime permissions, and supports scheduled callers through the same path. Output reads include status, provenance, pagination, truncation, and bounded event waits. Provider protocols are unchanged.

   Validation completed:

   • 504 tests passed across 8 affected files, including labels, authorization, and the deterministic headless toolkit workflow.
   • All five directly affected packages passed typechecking.
   • Formatting and changed-file lint passed.
   • check:changed reports only the established 3 mobile type errors and Knip’s 3 files / 74 exports.
   • Real local Jupyter execution verified the canonical interpreter, project working directory, NumPy import, result 42, and saved notebook outputs. The native viewer parser accepted that saved notebook. Owned kernel/server and temporary project files were cleaned up.

   Free eval context measurements:

   Measurement	Before	After
   System characters	7,669	7,669
   Tool-description characters	22,678	25,186
   Schema characters	66,121	71,429
   Tools	89	99

   Before/after dry runs built successfully for the notebook cases; the Forgejo control also passed request construction. Paid evals were skipped because no API key exists.

   The external jupyter-notebooks skill now prefers native tools and retains the interim fallback. Skill validation passed. Its change remains uncommitted on the shared dirty main; unrelated work was preserved. Review the named-skill diff.

   Full evidence and exact commands, affected-check results, and executed notebook are retained outside the worktree.

   Remaining gate: the owner’s independent Codex checker. No browser or real provider turn was run.
