From 158bf954c9b61267b6ab1f3cb2e73c94a2785c72 Mon Sep 17 00:00:00 2001 From: suryaiyer95 Date: Sat, 29 Aug 2026 11:22:06 -0700 Subject: [PATCH 01/10] feat(workspace): tell the model what the bound workspace serves MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit returns a redirect naming the engine tool. It did not make the model *pick* the engine first, so every session pays a wasted turn learning the rule. The only model-visible steering today is a sentence `describeNativeTool` appends to a description whose first line already matches user intent ("Execute SQL against a connected data warehouse."), and it never names the engine key — so even an obedient model cannot comply without a probe call. The routing table the model needs already exists as `inventoryLine`, and goes only to a TUI toast. Nothing in the system prompt mentions the workspace. `session/system.ts:129-142` records this repo's own benchmark finding: a lazily-described capability fired in "<1% of tool calls", and guidance placed at the END of a section was "treated as background reference rather than binding directive" while the same content placed FIRST was applied. The precedence suffix is exactly that shape. So state it in the system prompt instead, per turn, naming the exact engine keys, and say the converse explicitly so unserved types keep running locally. Purely additive by construction — 118 insertions, 0 deletions: - `awareness.ts` renders a string and nothing else. It does not touch `check()`, `derive()`, `redirectFor()` or any tool body, so which calls are shadowed and what a shadowed call returns are unchanged. - It returns "" in every state except a bound, attributed workspace with materialised engine tools. A session without a workspace assembles a byte-identical system prompt to before this commit. - `servedInventory()` is a projection over the snapshot the guard already uses, filtered through the same `servedFor`/`reachable`, so the section can never advertise a routing `check()` would not perform, nor one the caller's agent is forbidden to follow. - No tool descriptions change, so no existing description assertions move. Deliberate details: - Per capability, not per warehouse type. BigQuery serves execute only, so its line says explain and inspect stay on the local tools — claiming the type would steer the model off the only tools that work there. - The converse paragraph is never dropped under the char cap; without it the section reads as "prefer the workspace for everything", which is the over-steering failure this most needs to avoid. - The escape hatch speaks rather than falling silent: engine tools can still materialise with `--integrations=local` on, so silence would leave the model free to use tools it can see and should not. - An agent denied the engine keys renders no section, matching what precedence actually does for it. Verification: `bun run typecheck` clean. 19 new tests (14 awareness, 5 precedence), all passing. Full `test/altimate/` sweep goes 4420 -> 4439 pass with the same 3 pre-existing failures present on the untouched base commit (cross-file pollution in `default-target.test.ts`, which passes 12/12 in isolation on both).

No behaviour change: the full `test/altimate/` sweep is 4454 pass / 0 fail before and after. - `servedInventory()` returns a grouped `ServedType[]` instead of a flat list the caller immediately regrouped. `precedence.shadowed` is already grouped, so the flatten/regroup round trip was undoing work nothing asked for. This also drops two provably-dead branches (`shadowed.get(type)` after iterating `shadowed.keys()`; `byCapability.get(capability)` after `servedFor` already filtered on entry presence), and halves the per-type `PermissionNext.evaluate` work by deriving `local` from the same `servedFor` pass. - Deleted `localCapabilitiesFor()`. It was a third copy of `CAPABILITIES.filter((c) => !served.includes(c))`, already inline in `inventoryLine` and `warehouseListNote`; `local` now rides on the projection. - `ALL_LOCAL_TOOLS` is derived rather than hand-copied, and `CAPABILITY_COPY`'s `localTool` field is gone — every value equalled its key, because the `Capability` union IS the native tool id (`describeNativeTool` already relies on that identity). Output is byte-identical. - The disabled-state branch is a `Record` over `disabledReason`, not a ternary. The old test comment claimed adding a reason "fails to compile"; that was false — a `Union[]` annotation accepts a short list. A `Record` is genuinely exhaustiveness-checked: adding a sixth reason now raises TS2741 in both `awareness.ts` and its test, verified by doing it. - Corrected the module and call-site docs: `systemSection` runs once per STEP (inside the `while (true)` prompt loop), not once per turn. Noted why it is deliberately not memoised — a cached section outliving its snapshot would advertise routing that no longer holds. - Extracted `test/altimate/workspace/precedence-fixture.ts`. `bindTo`'s `attachOutcome` shape is coupled to the attach module's SERVING allowlist, so two hand-maintained copies break differently when it changes. Both suites now share the tool maps, warehouse configs and analyst ruleset; the awareness suite picks up the engine-less duckdb/redshift connections it had been omitting. - Dropped comments that restated an adjacent doc, and replaced rationale copied verbatim into tests with pointers to the source of truth. Not done, deliberately: `prompt.ts` and `precedence.test.ts` fail `prettier`, but they already fail on the untouched base, so reformatting them would add unrelated churn. The duplicated `short()` helper and the two `servedFor` sweeps in `describeNativeTool` are pre-existing and outside this diff.

The twice-declared `short()` helper is hoisted to module scope beside `CAPABILITIES`. The payoff is not line count: the toast, the `warehouse_list` row note and the model-facing prompt section now derive "what is served" from one function, so they cannot disagree about which capabilities a workspace serves — previously three independent walks of the shadow table. Kept deliberately separate: `short()` (terse — `execute/explain/inspect` for a one-line toast) and the section's `CAPABILITY_LABEL` (prose — "table stats / schema inspection"). Two audiences, and the section's whole thesis is that vague phrasing is what failed to steer the model. Behaviour is unchanged and the tests prove it byte-for-byte: the suite asserts exact output including "snowflake: execute/explain/inspect via workspace analytics", "bigquery: execute via workspace analytics" and "explain/inspect stay local". Verification: typecheck clean. Full `test/altimate/` sweep 4434 -> 4453 pass with the same single pre-existing failure on both (`tracing-rename-race` M3-natural, which also fails in isolation on the untouched base 40c57a890). Not done: `test/altimate/precedence-guard-order.test.ts` keeps its own SNOWFLAKE_TOOLS. It is a genuinely different fixture — three keys rather than four, and a different binding — so folding it into the shared module would change what that suite covers.

The intro is scoped to capabilities now. - The workspace name is customer-authored and lands in the system prompt: it is emitted as inert data (control characters stripped, whitespace collapsed, length bounded, JSON-quoted) with the numeric id named alongside. - The uncertain states (binding unreadable, engine unattributed, derivation failed) steer to the local tools the way the escape hatch does, without naming the unverified workspace. `check()` fails open there and the engine's tools stay visible, so silence left the model unguided. Silence is kept for the states with nothing to misuse, so an unbound session's prompt is still byte-identical. - When types are dropped for length the converse no longer forbids `datamate_*` for "types not listed" — the omitted types are served — and says the list is partial. The cap is a real ceiling: a single oversized line is dropped too. - Doc block moved onto `systemSection`; the refresh-per-step sequence and the pinned-catalog caveat are stated; the canonical driver type is noted.

The module's header claimed it returns "" in every state but a routing one. Four of the seven `disabledReason` values render text, so the sentence the whole "safe to land" argument rested on was false. It now states the scoped claim `DISABLED_COPY` actually implements, and says plainly which states speak and why. That claim was also not true of the code. `ALTIMATE_INTEGRATIONS` is process-wide and `derive` read it before the workspace link, so a pilot user who exports `--integrations=local` got a "## Workspace integrations" block in the system prompt — and a toast on screen — in every project, including ones with no link and no `datamate_*` tools at all. The hatch is now read after the link. Both orders disable routing identically, so this changes only which reason is reported; it still outranks `binding-unreadable`, because the flag is a fact about the session whatever the link says. `binding-unreadable` said "the bound workspace's engine could not be verified", but `currentBinding()` maps any throw from the strict reader to `unreadable`, which a project with no link can reach. The shared copy now claims only what holds in all three states that use it. Under truncation the section counted the omitted types twice, once on the list tail and again in the converse. The count stays on the list; the converse carries only the instruction. Tests: the existing hatch test bound a workspace in `beforeEach`, so unbound + hatch was never exercised — which is how the leak survived review.

Four assertions of the same branch, one of them mislabelled by appearance. The reason is now asserted, which is the actual point: the link read short-circuits ahead of the catalog. `nothing-materialised` silence is covered where it belongs — "a declared-but-absent integration renders nothing" and the exhaustive reason-to-copy table.
