qprompt-cli 0.1.3

Flight recorder for LLM apps

qprompt-cli

Internal trace utility for LLM workflows.
Goal: make answers inspectable with structured records of parsing, tool execution, evidence, and risks.

Why we use this internally

• Identify why a model answer is wrong without re-running blind.
• Detect when an answer claims tool usage that did not actually happen.
• Preserve a portable artifact for incident review and QA.
• Standardize trace shape across model/tool backends.

What is captured

• Request metadata: trace_id, timestamp, model, question
• Parse stage: intent, entities, assumptions, missing_context, suggested_tools
• Request envelope: model messages and available tools
• Tool execution: name, redacted input, output summary, status, error
• Evidence records: claim/source/evidence id
• Model response metrics: latency, token usage estimates (or provider usage when available)
• Audit output: claims, unsupported claims, risk flags

Explicit limitations

• No hidden chain-of-thought extraction.
• No neuron/attention internals for hosted closed models.
• Token usage depends on provider payload; may be estimate-only.

Install

python -m pip install -e .

Import:

from qprompt import Tracer

CLI

qprompt run "why did revenue drop in March?"           # real path: stub LLM, no synthetic tools
qprompt run "why did revenue drop in March?" --demo    # synthetic SQL + evidence (marked is_demo=true)
qprompt list
qprompt show <trace_id_or_path>
qprompt diff <trace_a> <trace_b>

The --demo flag is opt-in; the default never injects fake tool calls or evidence. Demo traces carry is_demo: true and are flagged on stdout/stderr so they can never be silently mistaken for real data.

Default storage:

.traces/YYYY-MM-DD/trace_<uuid>.json

Data contract

• JSON schema: src/llmtrace/trace_schema.json
• Runtime builder/validator: src/llmtrace/schema.py

Operational behavior

• Trace write occurs only after schema validation.
• Failed tool calls are recorded as step errors and surfaced as risks.
• Multi-month phrasing (e.g. "April vs March") is preserved in parsed period.

Integration notes

• Tracer.run(...) currently includes a mock model path for local validation.
• For production usage, replace the callable used by Tracer.chat(...) with provider-specific calls and pass back usage fields when available.
• For SQL/tool-backed workflows, run tools in code and pass outputs into the traced context; prompt text alone does not execute tools.
