feat(settings): user-facing prompt-cache TTL for Anthropic profiles (C6) - #2271
User-facing prompt-cache TTL setting (PR-C6, settings/UI): a "Prompt cache lifetime" control on the Anthropic provider profile (5 minutes default / 1 hour opt-in), completing the ADR-0006 phase chain (C5b knob emission -> C6 setting/UI).
Why
ADR-0006 Decision item 3. The emitter-side capability gate (shipped in #2264) is the ONLY gate (I2): the stored value is written verbatim; resolveCacheTtl re-checks promptCacheTtlSupport at request build and fails closed — a hand-edited 1h on a non-capable model never reaches the wire (byte-identical payload, no ttl key).
Implementation notes
Full persisted round trip per the repo's settings checklist: schema+default (packages/types/src/provider-settings/common.ts:40), ExtensionState via apiConfiguration, cachedState-bound control (SettingsView race rule), generic upsertApiConfiguration handler, getState/getStateToPostToWebview, import/export round-trip test (falsified by schema removal).
Capability-gated rendering: control only for models advertising promptCacheTtlSupport (3 hide-case tests).
i18n: 4 keys x 18 locales, programmatically verified.
Visual: gallery story anthropic-settings with programmatic geometry/contrast/overflow assertions (repo precedent LayoutContracts.visual.tsx); no pixel baseline committed because the CI container is Linux and host-rendered PNGs mismatch (existing baseline fails on this host) — regenerate via test:visual:docker:update if maintainers want one.
A storage-side TTL clamp proposed during development was deliberately DISCARDED as an I2 violation (second source of truth at the wrong layer); emitter-side coverage already pins the fail-closed behavior.
What: the OpenAI-native handler now sends a task-scoped `prompt_cache_key`
in the Responses request body on both body builders (streaming and
completePrompt), and no longer sends the `session_id` request header.
The key is `metadata.taskId`, falling back to the handler session id,
clamped to OpenAI's 64-character limit, and omitted for models whose
catalog entry has `supportsPromptCache: false`.
Why: OpenAI keys prompt-cache routing off the body `prompt_cache_key`
field. The `session_id` header we were sending is not part of the
prompt-caching API and is ignored on the public Responses API, so every
OpenAI-native task was leaving cache hit-rate on the table. The header
also carries an underscore in its name, which hardened gateways
(Envoy/nginx `underscores_in_headers`) reject outright, so it was a
latent 400 for anyone behind such a proxy with a custom base URL.
`prompt_cache_retention: "24h"` is untouched: it is the supported
lifetime control on the pre-5.6 models that set it in the catalog, and
the existing retention specs pass unmodified.
Impact: cache affinity now follows the documented body field, stable
across turns of one task and distinct across tasks. No usage
accounting, cost, or other request field changes. openai-codex.ts and
xai.ts are untouched: codex already sends a body key, and xai never had
the header.
…e rate
What:
- Add `cacheWritesPrice1h` / `cacheWritesPrice12h` to the ModelInfo schema plus
`deriveCacheWritesPrice1h` / `deriveCacheWritesPrice12h`, so the vendor
multiplier relationship is stated once in model.ts.
- Bill three write classes in `calculateApiCostInternal`: the 5m remainder is
derived as total - 1h - 12h (clamped at 0), so the classes always sum to the
aggregate and no token is billed twice or dropped.
- Scale the TTL rates with `cacheWritesPriceMultiplier` in long-context pricing.
- Carry `cacheWrite1hTokens` / `cacheWrite12hTokens` on `ApiStreamUsageChunk` and
read them from Anthropic `usage.cache_creation.ephemeral_1h_input_tokens`
(anthropic, minimax, anthropic-vertex) and OpenAI Responses
`input_tokens_details.cache_write_tokens_details.ttl_12h_tokens`
(openai-native `normalizeUsage` only).
- Thread the split through the Task usage accumulator, including the cancel-path
cost recomputation that runs when a provider yields no totalCost.
- Populate the rates: 22 Anthropic entries, 19 Bedrock Anthropic-family entries,
7 OpenAI GPT-5.6/6-class entries.
Why:
Anthropic bills a 1h cache write at 2x input versus 1.25x for 5m, and OpenAI bills
a 12h write at 2.5x versus 1.25x for 30m. The repo read only the aggregate
`cache_creation_input_tokens` and priced every write at the short rate, so a 1h
write under-reported by 37.5% and a 12h write by 50%. The vendors already report
the per-TTL split; it was being discarded.
Impact:
Reporting only. No request shape changes: the repo emits no `ttl` field, so live
traffic still reports 0/absent long-lived writes and pricing is byte-identical to
before (asserted against the historical cost literals). When the TTL knob lands,
a 1h write can no longer be billed at the 5m rate. 18 new tests fail on the base
blob; the new cost code has no surviving mutants.
…blocks
What:
- Pass `cacheWrite1h`/`cacheWrite12h` to the cost call inside `captureUsageData`.
The bag already carried them and fed the shared accumulator vars, but the
telemetry recompute passed only the aggregate write count, so a cancelled
request's telemetry billed every write at the short-TTL rate.
- Add `cacheWritesPrice1h`/`cacheWritesPrice12h` to the `tiers` schema and to the
four Anthropic and four Bedrock 1M-context tier blocks, derived from each
tier's own input price.
- Carry the tier's TTL rates through all three tier-merge seams (anthropic,
anthropic-vertex, bedrock) and derive them from the tier input price in the
OpenAI service-tier seam, so a flex/priority or 1M-context write is not billed
at the base tier's TTL rate.
Why:
Two under-reports survived the first pass. `captureUsageData` recomputes cost for
telemetry when a provider yields no final cost chunk (the cancelled-stream path),
and it dropped the split: 100k 1h tokens at claude-3-5-sonnet billed 0.375
instead of 0.6. Separately, the 1M-context tier merge overrode `inputPrice` but
not the TTL rate, so the entry-level rate derived from the 200K input price
survived: a 1M-context 1h write billed 6.0 instead of the tier's 12.0, a 50%
under-report.
Impact:
Both paths now bill at the correct TTL rate. Three new tests fail on the
pre-fix code (0.375 vs 0.6, and 6 vs 12); a fourth asserts the tier rate reaches
the cost function. No request shape changes.
What:
- Rename "bills a mixed 5m/1h split per class (0.465 case)" to
"(60/40 split, 0.51)".
Why:
The label cited a figure the test does not assert. A 60/40 split of 100k writes
at 3.75/6.0 costs 0.15 + 0.36 = 0.51, not 0.465. The assertion was already
correct; only the name was misleading, and a reviewer reading the label would
have expected a different number.
Impact:
Test name only, no behaviour change.
What:
- Add a per-tier case asserting the 12h write rate follows the tier's own input
price (default 25.0, flex 12.5, priority 50.0 for gpt-6-astra).
Why:
The service-tier seam was changed to derive the TTL rates from the tier input
price, but nothing pinned that behaviour. Without a test, a future edit could
revert to the standard-tier 12h rate and a flex/priority 12h write would be
mis-billed by 2x in either direction.
Impact:
Test only. Fails without the tier derivation (flex bills 2.5 instead of 1.25,
priority 2.5 instead of 5.0).
What: add a `promptCacheTtl` provider-settings knob ("5m" | "1h"), a
`ModelInfo.promptCacheTtlSupport` capability array, and a shared
`resolveCacheTtl`/`cacheControl` helper that the anthropic, vertex and
vercel-ai-gateway caching transforms plus the anthropic, anthropic-vertex,
openrouter, vercel-ai-gateway and zoo-gateway providers thread through.
Why: ADR-0006 phase 2. C5a (Zoo-Code-Org#2260) landed per-TTL write accounting, so a 1h
cache write is billed at 2x instead of the 5m rate. This is the matching
request-side mechanism: once the settings UI ships in C6, a user selecting 1h
causes Anthropic-shaped providers to emit `cache_control: { ttl: "1h" }`.
Impact: no behavior change by default. An unset knob resolves to `undefined`
and the marker stays the byte-identical `{ type: "ephemeral" }` literal, so no
`ttl` key is emitted unless the user opts in AND the resolved ModelInfo
advertises the capability. Absent capability means 5m only (I2), capability is
read from ModelInfo rather than id substrings, and every marker in a request
shares one resolved TTL (I4). Dynamic catalogs (OpenRouter, the gateways) carry
no capability data and therefore stay at 5m, as the ADR requires.
What: adds the 1h cache TTL selector to the Anthropic provider panel, gated
on the model's catalog capability, plus the four locale keys in all 18
locales.
Why: ADR-0006 decision item 3 ships the knob last, after the accounting
(C5a) and the mechanism (C5b) so no request can emit a 1h write that is
not priced. The control is the user-facing half; it renders only where
promptCacheTtlSupport advertises 1h (invariant I2), and selecting the
default writes DEFAULT_PROMPT_CACHE_TTL (undefined) rather than a literal
"5m" so an unset knob keeps emitting no ttl key (invariant I3).
Impact: Anthropic profiles gain an opt-in control; default behavior and
wire bytes are unchanged for every profile that leaves it alone.
Test: webview-ui Anthropic.spec.tsx 8/8.
What: adds the round-trip coverage the Persisted Setting Checklist asks for:
extension-side survival through getStateToPostToWebview (set and unset),
import/export schema preservation of both "1h" and "5m", and the
SettingsView cachedState buffer (restore, buffer-until-Save, and the
absence-vs-explicit-5m distinction).
Why: the knob rides apiConfiguration, so a missing schema field or a
missing state-post field would silently revert the control without any
type error. The import/export case is falsified by removing the schema
entry (test goes red), so it guards the field rather than the fixture.
Impact: test-only; no production behavior change.
Test: src 504/504 across the six affected suites, webview-ui 2235/2235.
… specs
What:
- openai-native: hash over-long task ids with sha256 hex instead of slicing to
64 chars. A slice drops the distinguishing tail, so two ids sharing a 64-char
prefix collapsed into one routing bucket. sha256 hex is exactly 64 chars, so
the result still fits OpenAI's cap.
- openai-native: clamp the 12h write subset at zero as well as at the write
total. A negative `ttl_12h_tokens` from a misbehaving gateway used to reach
the Task accumulator and the webview as a negative count.
- cost: cap the 1h and 12h write subsets at the remaining aggregate write total.
A malformed split (1h + 12h > total) billed the excess; 150k reported 1h
writes against a 100k total cost 0.9 instead of 0.6.
- Task.spec: replace the fixed 50ms sleep with `vi.waitFor` on the captured
telemetry call. The drain is fire-and-forget and touches the filesystem, so a
fixed sleep races it on a loaded worker.
- vercel-ai-gateway.spec: assert the TTL argument of the `addCacheBreakpoints`
mock call. The transform is file-mocked, so `JSON.stringify(mockCreate)` can
never contain `cache_control` and the old assertion could not fail.
- ttl.spec: compare raw `JSON.stringify` output against literal expected strings
in the byte-identical test. `toEqual` on round-tripped objects ignores key
insertion order, so a key reorder passed while the wire bytes changed.
Why:
Seven CodeRabbit "Minor" threads on the C5a/C5b stack. Three are production
correctness (cache-key collision, negative token count, overbilled split); three
are assertions that could not fail. The seventh thread's premise, forwarding the
TTL split into the telemetry recompute, already landed in b647ec7.
Impact:
Long task ids keep distinct cache buckets; malformed TTL splits can no longer
over- or under-bill or leak negative counts. No request shape changes for the
default path: the aggregate-only case still derives both subsets as zero.
What: adds an "anthropic-settings" gallery story and a matching visual test
that asserts the prompt cache TTL control's copy, default value, sibling
alignment, contrast and overflow behavior.
Why: the C6 control is a user-visible settings surface, and the repo asks
for gallery coverage on changes a reviewer would notice at a glance. The
story pins the default Anthropic model (claude-sonnet-4-5), whose catalog
entry advertises promptCacheTtlSupport ["5m","1h"], so the capability-gated
control actually renders.
Deliberately no toHaveScreenshot baseline: committed baselines are rendered
in the CI Linux container (visual-regression.yml) and run-docker.mjs states
host-rendered baselines are not reachable, so a Windows-rendered PNG would
fail the required webview-visual check. The assertions are geometric and
textual instead, following the LayoutContracts.visual.tsx precedent, and
they are falsifiable (a 7px injected offset turns the test red).
Impact: test/visual-infra only; no production behavior change.
Test: playwright -c playwright-ct.config.ts Anthropic.visual.tsx 1/1,
stable across two consecutive runs; eslint and tsc clean.

Anthropic settings now offer a 1-hour prompt-cache duration alongside the 5-minute default, when supported by the selected model.
Prompt-cache duration preferences are saved with provider settings and applied to supported requests.
Cache-write usage and costs now reflect 1-hour and 12-hour cache tiers for supported models.
Prompt-cache settings are available in additional languages.
This change adds provider-profile prompt-cache TTL settings, model TTL capabilities and cache-write rates, TTL-aware provider requests, and billing based on reported cache-write token splits. OpenAI Native requests also use prompt-cache keys in the request body.

Layer / File(s)
Summary
TTL contracts and model pricing packages/types/src/model.ts, packages/types/src/provider-settings/common.ts, packages/types/src/providers/*, packages/types/src/__tests__/*
Types define "5m" and "1h" TTL values, model capability metadata, TTL-specific cache-write rates, and rate derivation helpers. Anthropic and Bedrock catalogs add one-hour rates; selected OpenAI models add 12-hour rates.
The Anthropic settings view displays a TTL selector when the selected model advertises one-hour support. Tests cover selection, save, import/export, and state persistence. Locale files add selector text.
A shared resolver returns "1h" only when the setting and model capability allow it. Cache transforms and provider requests use the resolved TTL. OpenAI Native adds a model-gated prompt_cache_key, hashes keys longer than 64 characters, and removes the session_id header.
TTL-specific usage and billing src/api/transform/stream.ts, src/api/providers/*, src/core/task/Task.ts, src/shared/cost.ts, src/utils/__tests__/cost.spec.ts, src/core/task/__tests__/Task.spec.ts
Usage chunks add optional one-hour and 12-hour cache-write token subsets. Provider handlers and Task collection pass these subsets to cost calculations and background telemetry. Cost calculation resolves explicit or derived rates, caps TTL-specific counts at aggregate writes, and bills remaining writes at the short-TTL rate.

Explanation
No changed path meets the failure condition. promptCacheTtl accepts only "5m" or "1h" through promptCacheTtlSchema. resolveCacheTtl emits "1h" only for an exact setting value and a resolved model that advertises "1h"; missing capability fails closed. OpenRouter, Vercel AI Gateway, and Zoo Gateway retain their existing prompt-caching allowlists and support checks. The changes do not add a new secret or PII sink, execute input, or bypass approval controls.
Full details: Persistence Integrity
Explanation
No changed persistence defect found. promptCacheTtl is added to baseProviderSettingsShape, so it flows through providerSettingsSchema and PROVIDER_SETTINGS_KEYS. The existing save path sends the buffered profile, the message handler awaits upsertProviderProfile, and saveConfig awaits the secret-store write. Import and export also await their manager operations. DEFAULT_PROMPT_CACHE_TTL remains undefined; the UI displays 5m while resolveCacheTtl correctly emits no TTL for the default. The non-awaited webview message dispatch is unchanged and is not a new persistence path.

No changed lifecycle path meets the failure condition. The PR adds TTL resolution, cache markers, pricing fields, prompt-cache key hashing, usage counters, and a React select control. Added production lines introduce no listeners, watchers, timers, subscriptions, workers, or new abort controllers.

They do not cover configured promptCacheTtl: "1h" for a capable model or a configured "1h" value with absent capability. The streaming tests do not exercise this separate non-streaming call site.
Resolution
Add focused completePrompt tests in src/api/providers/__tests__/anthropic-vertex.spec.ts for a capable model with promptCacheTtl: "1h" and for a configured "1h" value with absent or unsupported promptCacheTtlSupport. Assert the emitted cache_control object contains ttl: "1h" only in the capable case and omits the ttl key in the fail-closed case.

Add an accept-path test for the TTL argument on createMessage.
The new handler test covers only the reject path. It asserts that the third argument to addCacheBreakpoints is undefined for a model without TTL capability. VercelAiGatewayHandler.createMessage passes resolveCacheTtl(this.options, info) as that argument, and no handler-level test asserts "1h" for a model whose catalog entry advertises promptCacheTtlSupport including "1h". A handler that always passed undefined would still pass this suite.
Add a sibling test. Use a model that is in the gateway prompt-caching set and has supportsPromptCache, with catalog info that includes promptCacheTtlSupport: ["1h"]. Set promptCacheTtl: "1h" and assert that lastCall![2] is "1h".
The test guidelines require accept-path and reject-path tests for guards through every public entry point. resolveCacheTtl gates the TTL on model capability, and createMessage is the public entry point that calls it. The gateway catalog currently supplies no TTL capability, so this is a test gap rather than a current production failure.

Add an accept-path test for VercelAiGatewayHandler.createMessage using a gateway

Assert that the Vercel default model info has no TTL capability.
The test titled "leaves dynamic-catalog defaults without capability so they fail closed" checks openRouterDefaultModelInfo.promptCacheTtlSupport but not vercelAiGatewayDefaultModelInfo. For the Vercel default, it checks only that the model id is in VERCEL_AI_GATEWAY_PROMPT_CACHING_MODELS. If promptCacheTtlSupport: ["5m", "1h"] were added to vercelAiGatewayDefaultModelInfo, this test would still pass.
The handler uses that info only when the gateway catalog does not supply the default model. In that case, RouterProvider.getModel() falls back to defaultModelInfo. The handler then passes it to resolveCacheTtl, which returns "1h" when the user has selected 1h. Catalog-supplied entries are not affected by this default-info change.

Add a tier-level 1h rate check for Anthropic and Bedrock catalog entries.
The catalog test checks only model-level cacheWritesPrice1h against inputPrice. A regression in a tier's 1h rate passes it. The Anthropic provider test covers the Sonnet 4.5 tier. The other tier entries have no equivalent check. Every tier entry in the Anthropic and Bedrock catalogs already sets its 1h rate to 2x its tier input price, so a tier-level check passes on the current data.

@webview-ui/src/components/settings/providers/__tests__/Anthropic.spec.tsx:
- Line 19: Remove the `any` annotations from the six mocked controls in the test
doubles for `Checkbox`, `VSCodeTextField`, `VSCodeButtonLink`, `Select`,
`SelectContent`, and `SelectItem`. Type each mock’s props and callbacks using
the corresponding real control prop types, preserving the behavior the test
relies on.

@webview-ui/src/components/settings/providers/__tests__/Anthropic.visual.tsx:
- Line 12: Add a focused Playwright screenshot assertion to the prompt cache TTL
visual test, targeting the rendered story with a stable snapshot name so visual
changes to the control are detected.
Review comments at @webview-ui/src/components/settings/providers/Anthropic.tsx:
- Line 120: Associate the prompt cache label with its selector in the
component’s prompt-cache settings UI: assign an id to the SelectTrigger and set
the label’s htmlFor to the same id so clicking the label activates the trigger.
Preserve the existing aria-label.

Review comments at @src/api/providers/__tests__/vercel-ai-gateway.spec.ts:
- Around line 469-472: Add an accept-path test for
VercelAiGatewayHandler.createMessage using a gateway prompt-caching model with
supportsPromptCache and catalog info advertising the “1h” TTL; configure
promptCacheTtl as “1h” and assert addCacheBreakpoints receives “1h” as its third
argument, alongside the existing reject-path coverage.

Review comments at
@packages/types/src/__tests__/cache-write-ttl-pricing.test.ts:
- Around line 61-67: Add a tier-level 1h rate assertion alongside the existing
Anthropic model-level check, iterating over tier entries in both
`anthropicFamilyEntries` and `bedrockAnthropicEntries`. When a tier defines
`cacheWritesPrice1h` and `inputPrice`, verify the 1h rate matches `inputPrice`
multiplied by `CACHE_WRITE_MULTIPLIER_1H`.
Review comments at @packages/types/src/__tests__/prompt-cache-ttl.test.ts:
- Around line 96-101: Update the test “leaves dynamic-catalog defaults without
capability so they fail closed” to also assert that
vercelAiGatewayDefaultModelInfo.promptCacheTtlSupport is undefined; import that
existing symbol from the Vercel AI Gateway provider module if needed, and keep
the existing OpenRouter and model-ID assertions.
Review comments at
@webview-ui/src/components/settings/__tests__/SettingsView.spec.tsx:
- Around line 1124-1127: In the SettingsView tests, add a regression case
alongside “preserves an explicitly stored 5m” that renders with promptCacheTtl
set to "5m", clicks save-button without changing the value, and verifies the
posted apiConfiguration retains promptCacheTtl as "5m".

What: type the six Anthropic spec mocks against the real control props,
give the prompt cache TTL label an htmlFor bound to the trigger id, and add
a label-activation assertion plus a pixel baseline to the visual test.
Why: CodeRabbit review of PR Zoo-Code-Org#2271 raised three Minor findings. The untyped
mocks let a wrong prop shape pass unnoticed, and the label wrapped no control,
so clicking it did nothing for pointer users.
Impact: label clicks now open the selector; the spec fails on a wrong-typed
callback, and the visual test fails when the label association is removed.
What: add the anthropic-prompt-cache-ttl-dark.png baseline rendered by the
pinned Playwright container in the webview-visual CI job.
Why: webview-ui/AGENTS.md forbids creating committed baselines from host
rendering, and Docker is unavailable on the authoring host, so the CI
container fallback supplies the authoritative PNG.
Impact: the visual test's screenshot assertion now has a baseline that
matches CI, closing the last CodeRabbit finding on PR Zoo-Code-Org#2271.
What: add a dedicated `anthropic/claude-3.5-sonnet` catalog row carrying
`promptCacheTtlSupport: ["1h"]`, and a test asserting the third argument to
`addCacheBreakpoints` resolves to `"1h"` when the knob is set.
Why: the existing pair only proved the reject path (`lastCall[2]` undefined)
and a bare `toHaveBeenCalled`. Nothing proved the accept path, so a regression
that dropped the third argument at the call site stayed invisible. The real
gateway catalog never sets `promptCacheTtlSupport`, so the capability has to be
injected by the test catalog rather than assumed from a real model.
Impact: test-only. The shared haiku row keeps no TTL capability, so the
existing reject-path test still asserts fail-closed behavior.
Fixed in 1f3cdf2: added the missing accept-path test for the TTL argument on createMessage, asserting the resolved "1h" reaches addCacheBreakpoints' third parameter. The test injects the capability through a new mock catalog row (anthropic/claude-3.5-sonnet with promptCacheTtlSupport: ["1h"]) rather than amending the shared row used by the reject-path test. Mutation proof: dropping the third argument at the call site fails only this new test.
Note for reviewers: parseVercelAiGatewayModel never sets promptCacheTtlSupport today and resolveCacheTtl fails closed, so the accept path is unreachable for real gateway models at the moment and the new row is a deliberate test injection. Spec 32/32, caching suites 50/50, lint and tsc clean.

What
User-facing prompt-cache TTL setting (PR-C6, settings/UI): a "Prompt cache lifetime" control on the Anthropic provider profile (5 minutes default / 1 hour opt-in), completing the ADR-0006 phase chain (C5b knob emission -> C6 setting/UI).
Why
ADR-0006 Decision item 3. The emitter-side capability gate (shipped in #2264) is the ONLY gate (I2): the stored value is written verbatim;
resolveCacheTtlre-checkspromptCacheTtlSupportat request build and fails closed — a hand-edited1hon a non-capable model never reaches the wire (byte-identical payload, nottlkey).Implementation notes
