What it does

Calle Script Advisor is an agent skill from CALLE-AI/awesome-phone-call-agents. Draft and check CALL-E phone-call task text and result schemas for clarity, safety, and extraction quality before any call is placed.

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts and reference files (for example `references/examples.md`, `references/safety.md` and `references/script-patterns.md`).

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

  • “/calle-script-advisor”

Requirements

  • Node.js

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. The goal - why this call is happening, in one sentence.
  2. The single decision the call must establish - the one thing that determines what happens next. If there seem to be several, pick the one…
  3. Who is calling and why - the identification line the agent should open with: who they are, who they are calling on behalf of (if anyone)…
  4. How to close the call - the instruction that ends the conversation cleanly once the ask is resolved.
  5. What to do on voicemail - whether to leave a message, what it should say, and whether to try again.

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/ (JavaScript), which the agent can run.

    Shell commands in SKILL.md call:

    • node

    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

Calle Script Advisor loads about 1.4k tokens when it runs, and up to ~4.5k if it reads all its reference files. Until then it costs about 39 tokens; SKILL.md has 838 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~39
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.5k

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-E Script Advisor

CALL-E's task field is free-form natural language, and its quality determines whether a call succeeds. A vague task produces a vague conversation, low extraction confidence, and an unusable result - and by the time that is visible, the call has already been placed and paid for. This skill turns CALL-E's own API guidance into an executable check that catches that before the call happens.

When To Use

Use this skill whenever you are drafting or reviewing a CALL-E task and result_schema, before any call is placed. That includes writing a new call from scratch, adapting an existing task for a new scenario, and reviewing a task or schema someone else wrote.

The Drafting Procedure

Before writing any text, gather:

  1. The goal - why this call is happening, in one sentence.
  2. The single decision the call must establish - the one thing that determines what happens next. If there seem to be several, pick the one that matters most and treat the rest as optional context.
  3. Who is calling and why - the identification line the agent should open with: who they are, who they are calling on behalf of (if anyone), and the reason for the call.
  4. How to close the call - the instruction that ends the conversation cleanly once the ask is resolved.
  5. What to do on voicemail - whether to leave a message, what it should say, and whether to try again.

Then, in order:

  1. Write the task text: identification, purpose, the single ask, edge-case handling, and the close. See references/script-patterns.md for the anatomy and a before/after rewrite.
  2. Write the result_schema to capture exactly the decision the call must establish - not everything that was discussed, just the answer this call exists to produce.

The Checking Step

Run scripts/check-call-script.mjs against the task and schema, and iterate until there are no errors:

bash
node scripts/check-call-script.mjs --task-file <path> --schema-file <path>
node scripts/check-call-script.mjs --task "..." --schema '{...}'

Both arguments are optional independently - lint a task alone, a schema alone, or both. The script prints findings grouped by severity, a score out of 100, and exits 1 if any error-severity finding exists, so it can gate a workflow.

Errors are not negotiable - fix every one. Warnings are judgement calls: read the suggestion, decide whether it applies to this call, and either fix it or consciously accept it. A warning left in place should be a deliberate choice, not an oversight.

See references/examples.md for three complete worked examples that pass the linter with zero errors.

Rules That Are Not Negotiable

  • Never invent a phone number. Use only the number the user provided or that the calling system resolved.
  • Never infer region, locale, or timezone from a phone number.
  • Never solicit sensitive personal data: Social Security numbers, credit card or bank account numbers, CVVs, PINs, passwords, dates of birth, or a mother's maiden name. See references/safety.md.
  • Always include an unknown (or unclear / not_stated / undetermined) enum member for anything the call may fail to establish. CALL-E's own docs recommend this explicitly, and it is what lets a downstream integration tell "the answer is no" apart from "there was no answer" - the sibling plugins/zapier-calle refuses to mark a call actionable when a required field comes back with one of these values, so the enum member is not decoration.
  • Ask the schema for its own evidence. Beside any field an automation will act on, add a <field>_quote string described as the recipient's exact words that establish the answer above. It costs nothing - the extraction model is already reading the transcript - and it is the only thing that separates an answer drawn from the call from one drawn from thin air, since both arrive as equally well-formed JSON with equally high confidence. The sibling plugins/zapier-calle verifies that quote against the transcript and sends the call to human review when it appears nowhere the recipient spoke. Ask for a full spoken sentence rather than a word: a one-word quote can match by coincidence. List the _quote field in required alongside the field it supports. A quote the model may omit is a check that switches itself off on exactly the call that had no evidence to offer, since a missing key is nothing for a verifier to examine; requiring it turns a silent pass into a loud failure.
  • Mark a field required only when the workflow genuinely cannot proceed without it. required is a contract: an integration that checks it will send the whole call to human review when the field is absent or unknown. Requiring a nice-to-have field turns every partially-successful call into manual work.
  • Never let the script imply a commitment the caller cannot honour - no promised callback times, approvals, or guarantees the agent is not authorized to make.

Read references/safety.md before drafting any task that touches consent, disclosure, calling windows, or a do-not-call request.

Progressive Disclosure

This file stays focused on the workflow. Detail lives in references/:

  • references/script-patterns.md - the anatomy of a good task, with a before/after rewrite.
  • references/safety.md - consent, disclosure, sensitive data, calling windows, and do-not-call handling.
  • references/examples.md - three worked examples (appointment confirmation, on-call acknowledgement, lead qualification), each verified against the linter.
