call-arithmetic-accuracy-auditor SKILL.md skillA
call-arithmetic-accuracy-auditor from calle-ai/awesome-phone-call-agents is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Offline experimental transcript auditor that recomputes the arithmetic a CALL-E voice agent SPOKE (quantity-times-price totals, line-item sums, percent-off results, balance-due subtraction, clock durations) against the agent's own stated factors and grades ALL_COMPUTATIONS_CORRECT, ARITHMETIC_ERRORS_FOUND, UNVERIFIABLE_COMPUTATIONS_ONLY, or NO_SPOKEN_COMPUTATIONS, plus a factors-first goal crafter; not a pricing database, a billing system, or authorization to act.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# call-arithmetic-accuracy-auditor

Most QA measures whether a total was disclosed. Almost none measures
whether the total was arithmetically true given the numbers the agent
itself just spoke. This skill reads a finished call transcript,
recomputes every spoken computation from the agent's own stated factors,
and grades each one CORRECT, INCORRECT, or UNVERIFIABLE - then rolls the
sentence grades into one verdict a reviewer can act on.
## Why This Skill Exists
LLM arithmetic is not reliable enough to skip verification. Dziri et al.
("Faith and Fate", arXiv:2305.18654) show transformers solve
composition problems by pattern matching, not computation. Mirzadeh et
al. (GSM-Symbolic, arXiv:2410.05229) show accuracy degrades when only
the numbers change, so a clean-sounding factor sentence does not
guarantee a correct total. Wei et al. (arXiv:2505.15000) show spoken
math is worse still for cascade ASR+LLM pipelines - exactly CALL-E's

How to install
mdr add calle-ai/awesome-phone-call-agents/call-arithmetic-accuracy-auditor@sha256:010ed438460e7eabThe line at the top of this page pins the label git:20261020.8518e0f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
