What it does

Messaging Performance Analyzer is an agent skill from aiskillstore/marketplace. Analyzes Sent message delivery, webhook, and activity data to explain funnel drop-offs, delivery failures, read-rate gaps, channel fallback, and suspicious performance changes. Use when a user says MDR, delivery report, message activity, webhook event, failed messages, low delivery rate, RCS fallback, WhatsApp read rate, SMS filtering, campaign performance, or asks why messages did not arrive.

Its SKILL.md is about 3.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 11 other files, including scripts and reference files (for example `agents/openai.yaml`, `references/mdr-status-codes.md` and `references/performance-diagnosis-playbook.md`).

It sits in Backend & APIs, covering Webhooks. It works with WhatsApp. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.

When your agent uses it

  • A user says MDR
  • Delivery report
  • Message activity
  • Failed messages

Example prompts

  • “Use the messaging-performance-analyzer skill to analyz Sent message delivery, webhook, and activity data to explain funnel drop-offs, delivery…”
  • “/messaging-performance-analyzer”

Requirements

  • Python 3

Workflow steps

7 steps, taken from the step headings in SKILL.md.

  1. Pin the question before slicing the funnel
  2. Build cohorts from Sent message IDs
  3. Normalize lifecycle stages to Sent’s documented statuses
  4. Check webhook health before diagnosing delivery
  5. Split by channel before naming a root cause
  6. Quantify impact before recommending fixes
  7. Convert the diagnosis into the next action

What it can do on your machine

Read from SKILL.md and the folder at commit ad8daf7. 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 3 files in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python

    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

Messaging Performance Analyzer loads about 3.3k tokens when it runs, and up to ~9.8k if it reads all its reference files. Until then it costs about 107 tokens; SKILL.md has 1,587 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~107
When it runs · the whole SKILL.md, loaded when a task matches
~3.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~9.8k

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,587 words (~3,301 tokens).
