What it does

Call Agent Certainty Calibrator is an agent skill from CALLE-AI/awesome-phone-call-agents. Offline experimental CALL-E transcript helper that flags agent statements of specific values absent from the goal facts and callee turns (over-assertion) and goal facts spoken with hedges but no source attribution (over-hedging), plus a three-tier calibrated-wording goal template. It is not proof the agent invented anything, a measure of internal confidence, or authorization to act.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including scripts and reference files (for example `references/example-transcript-calibrated.json`, `references/example-transcript-overassertive.json` and `references/example-transcript.json`).

The repository describes itself as: Portable phone-call Agent Skills, apps, examples, adapters, and scheduler recipes for AI agents. The licence is MIT.

Example prompts

  • “/call-agent-certainty-calibrator”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit 38d4118. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 2 files in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python3

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Call Agent Certainty Calibrator loads about 1.2k tokens when it runs, and up to ~4k if it reads all its reference files. Until then it costs about 104 tokens; SKILL.md has 552 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~104
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

call-agent-certainty-calibrator

An agent that invents specifics is worse than one that says 'I don't know'. An agent that hedges its own record is worse than useless.

Language models can express calibrated confidence in words - and, left unchecked, they drift both ways: asserting specifics nobody gave them ("free delivery on Friday!") and softening facts they were told to state ("I think it might be $45?"). On a phone call both failures are audible, and both end up in the outcome. This skill grades the agent's stated values against the goal it was given.

When To Use

  • after any fact-bearing CALL-E call, together with the goal text (or plan JSON) the call was built from
  • when an outcome contains a value nobody remembers putting in the goal
  • before placing calls, to craft wording that speaks record facts with authority and admits gaps honestly

When Not To Use

  • without the goal file; calibration is graded against the goal's facts and the CLI requires it
  • to prove the agent fabricated a value; an OVER-ASSERTED value may be true and simply missing from the goal text - the card routes to verification, always
  • on the callee's certainty; provenance-grade grades how the callee knew what they said
  • during a call; strictly post-call analysis plus pre-call goal crafting

Workflow

Audit a finished call
bash
python3 scripts/agent_certainty_calibrator.py analyze \
  --transcript path/to/call-result.json --goal-file path/to/goal.txt

Reads the real get_call_run result shape ({status, result: {transcript}}) or the flat fixture shape used by sibling skill fixtures; the goal file is plain text or a JSON with a goal field. Emits a card:

  • goal_facts: amounts, dates, times extracted from the goal text
  • over_assertions[]: agent-stated values in neither the goal facts nor any callee turn - unsourced specifics
  • over_hedges[]: goal facts spoken in a sentence with hedge words ("i think", "might be", "around", ...) and no source marker
  • calibrated_statements: goal facts stated plainly or attributed ("our records show...") - source attribution overrides a hedge
  • verdict: CALIBRATED / OVERASSERTIVE / OVERHEDGED / MIXED, plus unclear paths (empty transcript, no agent turns, goal without extractable facts)

Values a CALLEE introduced and the agent merely confirmed are never over-assertions: repeating the person's own value back is confirmation, not invention.

Show full SKILL.md (206 more words)Show less
Craft the calibrated goal
bash
python3 scripts/agent_certainty_calibrator.py craft --scenario calibrated-fact-stating

Emits the plan_call inputs JSON whose goal implements three tiers of verbalized confidence: record facts stated with attribution, estimates labeled as estimates, and gaps admitted exactly.

Scientific Foundation

ResearchRelevance
Teaching Models to Express Their Uncertainty in Words (Lin, Hilton, Evans, TMLR 2022, arXiv 2205.14334)Established verbalized confidence: models can and should express calibrated uncertainty in language - our three-tier wording operationalizes it for calls
Can LLMs Express Their Uncertainty? An Empirical Evaluation of Confidence Elicitation in LLMs (Xiong et al., ICLR 2024, arXiv 2306.13063)Empirical demonstration that verbalized confidence is often miscalibrated - the failure this skill audits on the transcript axis

Citation notes recorded during verification: Lin et al. appeared in TMLR 2022 (arXiv 2205.14334); Xiong et al. at ICLR 2024 (arXiv 2306.13063). This skill compares lexical value statements only, has no access to model internals, and labels every output analysis_mode: "heuristic".

Differences from sibling skills

  • call-sycophancy-guard catches the agent folding under the person's pushback; this skill catches unsolicited drift - invention and groundless hedging with nobody pushing.
  • provenance-grade grades the callee's epistemic state; this skill grades the agent's stated certainty against the goal record.
  • call-cross-call-consistency-checker compares the organization across calls; this skill compares the agent against its own instructions within one call.
