feat: Glob pagination, read-only tools in side questions, and MCP structured results - #303
Merged

Conversation
Preserve an MCP tool's structured payload alongside its text and media blocks, dropping the structured copy only when a text block already carries the same complete JSON value, and escape angle brackets in the serialized extras instead of stripping literal closing tags. Warn at config load when a [models] entry has no model field, with a hint when an unquoted dotted alias parsed as a nested table. Config sections now contribute load-time diagnostics through a hook. Scrub every ambient product env var in the engine and gateway test setups and give the SDK, client and extension projects an explicit integration-test timeout.
…dels Side questions started with /btw can now call Read, Grep and Glob so answers can rest on current file contents; every write or execute tool stays rejected. The subagent model list now always names what "primary" is bound to, drops the duplicate main-model marker, states that pool entries do not inherit the caller's thinking level, and the dynamic-workflow tool renders the pool as a one-line summary instead of repeating the block.
Glob now takes offset and head_limit, defaults to 100 matches, and accepts head_limit=0 to lift the match-count limit. Every page stays within the output character limit, ends on a complete path, reports the range it covers, and gives the next offset when more matches remain. The tool card counts only paths, and marks a page that is not the last.
turn_ended now carries the engine error code when a turn fails, session attribution keys emit empty strings so they survive payload flattening, and properties a sink cannot accept are reported through a new onUnexpectedError hook instead of vanishing. Properties are sanitized when the sink accepts the event, so drops on events queued before initialization are reported once a handler is installed.
Tower missions take an optional context field that carries the user's own sentences verbatim into the mission file and every briefing, so worker and reviewer see the intent and not only a paraphrase. Reviewer briefings now include the mission text and the author's own report with an intent-first checklist, and workers escalate substantive ambiguity to the tower instead of guessing. Tower spawns honour the configured subagent timeout instead of a fixed two hours, and the /tasks list shows each background agent's model.
Ctrl+X on a row asks for confirmation and deletes the session. The picker stays mounted and locks input while the deletion runs, so nothing races the swap; deleting the current session closes it and starts a fresh one, and a failed delete reattaches to the session that survived.

In `@apps/pythinker-code/src/tui/components/messages/tool-renderers/chip.ts`:
- Line 112: Update the file-counting logic around the files counter to recognize
and skip GlobTool metadata diagnostics—including traversal, timeout, truncation,
sensitive-file, and complete-page match footer lines—before incrementing files.
Reuse the existing GLOB_PAGE_HEADER and GLOB_NOTICE matching logic in the
relevant chip renderer and preserve counting for actual file entries.
In `@packages/agent-core-v2/src/app/config/configService.ts`:
- Around line 569-575: Update the configuration mutation paths using
rebuildEffective, including persisted set, replace, and replaceSections, to
recompute diagnostics for affected sections immediately after changes. Extend
revalidateDomain for sections registered after load, replacing prior diagnostics
for each affected section rather than appending so warnings disappear when
configuration is fixed. Add regression tests covering writes, late registration,
and warning removal.
In `@packages/agent-core-v2/src/features/tower/tools/plan/plan.ts`:
- Line 21: Update TowerPlanToolInputSchema and the TowerStore.plan build-mission
path so build missions require at least one task containing non-blank text,
while preserving taskless behavior for other mission types. Adjust the existing
taskless build fixture to include a valid task, and add Vitest coverage for
omitted tasks, an empty task list, and blank task text.
In `@packages/agent-core-v2/src/features/tower/tools/spawn/spawnTool.ts`:
- Around line 449-453: Move mission-file access out of the spawn tool by adding
a mission-text reader to TowerStore and using it for both this mission read and
the existing worker prompt read. Update the relevant spawn-tool flow to call
TowerStore instead of directly importing or invoking node:fs, while preserving
the current mission content and trimming behavior.
- Around line 461-463: Update the reviewRequest formatting in spawnTool.ts so
reviewRequest.body is enclosed in an explicit data section with instructions to
treat it only as evidence and ignore any directives it contains before
processing the reviewer checklist. Add a test covering a body with an embedded
directive.
In `@packages/agent-core-v2/test/features/btw/btw.test.ts`:
- Around line 118-130: Update the test using BTW_READONLY_TOOLS to assert that
the allowlist contains its expected read-only tool members before entering the
loop, while preserving the existing per-tool decision assertions.

… missions Count only real paths in the Glob result chip: prefer the page header's own range when present, and ignore the diagnostic and footer lines the tool emits around the matches. Recompute configuration diagnostics per domain, so a persisted write or a section registered after startup refreshes its warnings instead of leaving stale ones until the next reload. Require at least one non-empty task on a tower build mission; read-only survey missions still need none. Move mission-file reads into the tower store, and fence the author's review-request in the reviewer briefing so its text is read as evidence and never as instructions. Update smol-toml to a release that is not affected by GHSA-7w5x-hrqm-74c2.
…tures Complete the identity rename in the VS Code extension changelog: the 0.6.x blocks still carried the old product name, repository links, SDK scope, home environment variable and setting keys that the newer entries in the same file already use in their current form. Drop a stale release note describing a managed OAuth provider id the product does not ship. Rename arbitrary model ids in the extension test fixtures to neutral placeholders.

Rebuild the "ignored invalid config section" warnings with each validation pass, so a write that fixes a section clears its warning instead of leaving it until the next reload. Neutralize an author-account fence tag written inside a review request, so a worker cannot close the untrusted-data block and address the reviewer directly. Document that the subagent timeout also governs tower workers and reviewers, and drop a leftover unused variable in the session-picker startup test.

`[subagent] timeout_ms = 0` already means "no timeout", and the sibling dynamic-workflow variable accepts the same value, but the subagent environment variable rejected `0` and silently fell back to the configured value. Accept a non-negative integer, and ignore a blank value rather than reading it as zero.

Problem
Eight independent gaps across the agent engine, CLI and telemetry:
/btwvetoed every tool call, so a question about the codebase could only be answered from memory.primarywith its alias only when the caller's model happened to be in the pool — that is, it stayed anonymous exactly when the annotation was needed — andAgentDynamicWorkflowrepeated the whole block.[models]entry written without amodelfield (most often an unquoted dotted alias that TOML parsed as a nested table) failed silently.turn_endednever carried the error code, session attribution keys were dropped by payload flattening, and properties a sink could not accept vanished with no report./tasksdid not show which model a background agent runs on.What changed
Per commit:
bc6abb3MCP structured results + malformed[models]warning. The structured payload is dropped only when a text block parses to the identical JSON value — compared withisDeepStrictEqualbehind a reviver that refuses any numberJSON.parsewould round, so a summary, a media block or a rounded copy never suppresses it. Serialized extras now escape<instead of stripping literal closing tags, which preserves the values. Config sections gained acollectDiagnosticshook (mirroring the existing deprecations contribution); the models section uses it to warn on an entry with nomodel, with a hint naming the quoted table when an unquoted dotted alias produced a nested table. Also scrubs every ambientPYTHINKER_CODE_*variable in the engine and gateway test setups, and gives the SDK, client and extension projects an explicit integration-test timeout.2e3f6d7/btwread-only tools + subagent model disclosure.BTW_READONLY_TOOLS(Read, Grep, Glob) passes the veto listener; every write and execute tool still returns the deny message. Mirrored into the v1 engine —DenyAllPermissionPolicytakes an allowlist — because the v1↔v2 parity suite compares both side-question contexts.primarynow always renders asprimary (= <alias>), the duplicate[main model]marker is gone, a closing line states that pool entries do not inherit the caller's thinking level, andAgentDynamicWorkflowrenders a one-line summary.6e89460Glob pagination.offsetandhead_limit(default 100,0lifts the match-count limit). Every page still fits the output character limit, ends on a complete path, reports the range it covers and gives the next offset when matches remain; a page that cannot fit one complete path plus its diagnostics returns an error instead of a partial path. The tool card counts only paths and marks a page that is not the last.434e97dtelemetry attributes.turn_endedcarries the engine error code; session attribution keys emit empty strings so they survive flattening; a newonUnexpectedErrorhook reports properties the sink could not accept. Properties are sanitized when the sink accepts the event, so drops on events queued before initialization are reported once a handler is installed, and the hook runs behind a guard so a faulty host handler cannot aborttrack().c84f5dftower. Missions take acontextfield holding the user's own sentences verbatim, rendered into the mission file and every briefing. Reviewer briefings embed the mission text and the author's own review-request behind an intent-first checklist; workers escalate substantive ambiguity with aclarify-requestinstead of guessing, and reconcile completion reports task by task.TowerSpawnToolresolves the timeout through the[subagent]config instead of a hardcoded two hours, and reports the bound model and effective thinking effort in the task info, which/tasksrenders.38ac69fsession deletion.Ctrl+Xon a picker row asks for confirmation and deletes. The picker stays mounted and holds the input lock until the replacement session is ready, so no prompt races the swap; deleting the current session closes it first (no events from a dying session reach the UI) and starts a fresh one; a failed delete reattaches to the session the engine kept, falling back to a new session only if it is gone.4aee74cchangesets,90e3495docs.Scope deliberately excluded: the gateway-side half of session deletion (
event.session.deletedover WS and the serialized cleanup route) is not in this PR — the CLI half stands alone on the existingharness.deleteSession.Risk
Medium. Three behaviour changes are visible to the model rather than to the user: MCP results now carry more content, the subagent model prose changed, and
/btwcan read files. The/btwchange widens what a side-question agent may do — it is limited to three read-only tools, and the deny path is unchanged for everything else.The telemetry change alters emitted values (
''instead ofnull); thepfc_event prefix and ingest hosts are untouched.Verification

Every commit is independent and revertible on its own. Residual risk is the model-facing prose and the wider MCP payload; both are covered by tests that assert the exact rendered text.
