These are local tokenizer estimates, not provider usage, bills, +or real-model task success measurements. + +## Initial schemas + +The seven original meal functions use 820 `cl100k_base` tokens or 850 +`o200k_base` tokens after serialization by the production OpenRouter adapter. +The compact `meals` tool plus `describe_action` use 188 or 190 tokens, +respectively. This is a 77.1–77.6% reduction in the initial meals schema. + +An all-listed-capabilities configuration has 50 tools before the pilot and +45 afterward. It enables both search providers, sandbox, canonical training, +weather, skills, memory, custom data, reminders, Google Health, durable files, +and speech. Gmail remains unloaded. Its complete schema decreases from +6,885–7,009 tokens to 6,253–6,349 tokens, about 9.2–9.4%. This constructed +configuration is not a measurement of a running deployment. + +The generated parameter models also supply discovery schemas. Discovery moves +selected schemas into conversation history; it does not eliminate their cost. + +## Controlled workflow replay + +A deterministic `BaseLlm` supplied model responses to real ADK `Runner` and +`App` instances. Each run used an isolated SQLite database, the production +root instruction, temporal instruction plugin, domain policy plugin, tool +registry, and `build_chat_request(...).create_kwargs(stream=False)` adapter. +The flat baseline used the original seven handlers and the original nutrition +policy from base commit `4e10c3f`. The compact runs used this change's policy. +The replay verified successful tool responses; the logging case independently +verified exactly one 95-calorie entry in SQLite. + +The user messages were "Log one apple with 95 calories on 2026-10-20." and +"Show my calorie summary for 2026-10-20." A direct path called the operation +and then produced a final response. A cold path first called `describe_action`, +then called the operation, then produced a final response. Both compact paths +called the operation through `meals`. + +Token counts below sum compact JSON representations of **all input request +payloads**, including tools, instructions, conversation history, and tool +results. They use `cl100k_base`; `o200k_base` showed the same direction. + +From the repository root, reproduce the replay and both tokenizer counts with: + +```bash +uv run --with tiktoken==0.12.0 python scripts/benchmark_meal_tools.py +``` + +The tokenizer is an isolated measurement dependency, not an application +dependency. Its first run may download public tokenizer vocabularies. The +harness reads the original policy with `git show 4e10c3f:src/blacki/prompts/policies.py`, +so that base commit must be available locally. It creates and closes temporary +databases and never reads deployment credentials. Temporal context can cause +small count differences on later dates. + +| Workflow | Flat input tokens | Compact direct input tokens | Compact cold input tokens | +| --- | ---: | ---: | ---: | +| Log one meal | 19,332 | 18,179 | 28,078 | +| Read calorie summary | 19,324 | 18,171 | 27,635 | +| Model calls per workflow | 2 | 2 | 3 | + +The direct path reduces total input by about 6%. Cold discovery increases it +by about 43–45% because it sends the complete context through another model +call. Tokenized model output JSON was 52–61 tokens for the flat paths, 60–69 +for direct dispatch, and 96–104 for cold discovery. These output counts describe +the scripted responses, not actual generated or reasoning token usage. + +The direct path assumes the model already knows the arguments without needing +discovery in this turn. It does not include an earlier discovery transcript and +is not a measurement of a warmed conversation. The replay does not establish +how often a real model selects either path, actual provider caching or token +framing, latency, or task success rates. + +## Validation and rollout boundary + +`tests/tools/test_meals.py` exercises all seven actions with real SQLite +storage, local saves with failed remote export and explicit requeue, rejected +arguments without writes, owner isolation, private-chat restrictions, +read-only discovery, privacy, progress, retry identity, and a real runner +continuing completed historical `log_meal` call/response events. The serialized +provider-schema test guards the initial payload reduction independently of +the domain dispatcher. + +Run the relevant checks with: + +```bash +uv run pytest tests/tools/test_meals.py tests/test_tools_boundary.py +``` + +The initial schema target is met. This pilot does **not** establish a general +cost reduction. Expansion to other domains requires representative real-model +evaluation of total input/output usage, discovery frequency, repeated actions, +latency, and mutation correctness.
