_llm called env_manager.set_env() at import time, which connected to a private
ArangoDB to fetch secrets. That single line meant a fresh clone could not start,
regardless of what else was configured. Both packages also lived in separate
private repos and were gitignored here, so the code shipped without them.
packages/llm/ is 780 lines against _llm's 1750. Dropped as unused by this project
(measured, zero call sites): token counting and message trimming, image/vision
handling, make_summary, the ollama-specific paths, the query/user_input/context
argument style, and the self-mutating provider_quirks.json cache.
Kept and reworked:
- tools.py, the docstring -> JSON-schema tool registry, which has no equivalent
in the cuj-fup client and which llm_tools.py depends on entirely.
- The provider quirks that actually matter: vLLM-only extra_body fields stripped
for hosted providers, enable_thinking disabled at template level when think is
off, reasoning models (o1/o3/o4/gpt-5) switched to max_completion_tokens.
Adopted from cuj-fup's client: LLMConfig as a dataclass instead of 20 constructor
kwargs, the SDK's native max_retries instead of hand-rolled backoff, and error
messages that name the likely cause.
Fixes a latent bug: Optional[list[str]] parameters were advertised to the model as
strings, because get_origin(Optional[X]) is Union, so neither the schema mapping
nor the list coercion in execute_tool fired. `parties`, `people` and `focus_ids`
were all affected.
Also drops a dead SELECT-only guard in execute_tool that keyed on a parameter name
(`sql_query`) that no tool has ever used. Real SQL hardening is tracked separately.
Verified: `import backend.app` succeeds with all external network blocked and zero
outbound connection attempts; all 12 tools register; live vLLM calls confirmed for
plain generation, structured output via format=, tool execution, and the
error-returns-a-string contract that call sites branch on.
