Anthropic and Ollama endpoints, called over plain HTTP — no vendor SDKs. - **Skill harness** (`ai/harness`): prompt layering, validation of the structured output, and **one repair retry**; if the repair also fails the - run fails — no silent fallback. Every call is recorded in `ai_runs`. + run fails — no silent fallback. Every run writes one `ai_runs` row when it + ends, covering the repair turn too, with status `ok`, `repaired`, + `bad_output` or `provider_error`; a prompt that cannot be rendered is + `bad_output` and a provider that cannot be built is `provider_error`, both + with no turns. The harness builds the provider itself from the settings + and the decrypted API key (`presets.FromSettings`), so the key it redacts + is always the key the provider sends. Request and response + bodies are redacted before they are stored: the decrypted API key, + Authorization and API-key header values, Google Chat webhook URLs and URLs + with key-like query parameters are removed, inside JSON strings too; the + skill, provider and model columns are redacted the same way. Writing the + row is bounded: a run whose work ended in time must write its row before + the skill's deadline or it fails with `llm.ErrTimeout` and its row records + the timeout; a failed run's row has a further fixed bound, and if even + that write fails the run returns the write error with its own and no row + is stored. A stored row's status therefore always matches what the caller + received. + `harness.Purge` deletes rows older than `harness.RunRetention` (30 days), + clearing the `suggestion_batches` and `week_plans` references first. The + harness does not call it: the scheduler's daily `ai_runs` purge + (Feature 20) must call `harness.Purge` with `now - RunRetention`. +- **Concurrency guards** (`harness.Guard`, one per process): `harness.Run` + takes a scope key, and concurrent runs of one skill with one scope share a + single in-flight run and its result, error included (single-flight); runs + with different scopes are independent. A semaphore lets at most + `harness.DefaultMaxCalls` (2, set by `NewGuard`) LLM calls run at once; + waiting for a slot honours the context. Each skill declares a timeout + (`harness.DefaultTimeout`, 60 s, unless it needs another) bounding the + whole run, slot waits and repair turn included; a run past it fails with + `llm.ErrTimeout`. A caller whose context ends gets the context error; the + shared run is cancelled, freeing its slot, once no caller waits for it. +- **Prompt layering** (D-007): each skill version's prompt is a + `text/template` file embedded from `ai/skills/prompts/` + (`.v.tmpl`). The system prompt is always, in order: + [1] the admin persona (`ai_settings.system_prompt`), [2] the skill's + instructions, [3] the household context block, [4] the output contract + with the JSON Schema — the contract is always last. The user message comes + from the skill's input. `checksums.txt` pins every template; changing one + without a version bump fails the tests. +- **Household context** (`harness.BuildContext`): layer 3 holds today's date + and weekday in the household timezone, the Regulars, the Quest log, the + last 60 passed Side quests and the plans of the last four ISO weeks. A + character budget trims the oldest plans first, then the oldest passes; + Regulars and the Quest log are never trimmed. +- **Name dedupe** (`harness.Normalize`, `harness.Similar`, `harness.Deduper`): + a dinner name is normalized by lowercasing, dropping combining marks and + folding precomposed letters to their base letters through a table generated + from Unicode data (`gen_folds.py`), so composed and decomposed spellings + match, stripping punctuation, dropping filler words (easy, best, homemade, quick, simple, + the, a, recipe, classic) and collapsing whitespace.
