message-test-designer

message-test-designer is a skill for Claude Code from aaron-he-zhu/aaron-marketing-skills. It costs 190 tokens per session (3,327 once invoked), scanned A, original, Apache-2.0.

A test plan for checking whether people understand a proposed brand message before it is widely used. It defines the hypothesis, participants, message samples, comprehension tests, success limits, and when to revise.

In plain words
What is it for?
It helps design five-second comprehension tests and message-market-fit studies, where a target audience evaluates whether a message is clear and relevant.
Why use it?
It reduces the risk of scaling a tagline or narrative that people misunderstand. It also provides a clear decision rule for changing the message after testing.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

message-test-designer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Message Test Designer

Designs the pre-scale message validation for a candidate narrative — the hypothesis, the target panel and recruit criteria, the comprehension / 5-second / message-market-fit (Wynter-style) protocols, the stimulus set drawn from the canon, the success thresholds, and the stop/revise decision rule. It sits in the Evaluate phase of the TALE loop and feeds the E sub-item the message is tested before scale (comprehension / 5-second / message-market-fit panel) — see tale-benchmark.md. Its output is a test design spec only: this skill designs the test, hands execution to the experiment builders, and never runs the panel, analyzes results, or adjudicates a claim. It also encodes the E1 discipline downstream — a message that fails its test triggers revision, not louder repetition (the narrative-whiplash guardrail's counter-move).

Scope guard: this skill produces the test design document only. It does not run the panel or the A/B experiment (hand execution to send-experiment-designer or ad-test-designer), analyze the returned results (use performance-analyzer), author or edit the message under test (message-system-architect owns the durable house), adjudicate any claim in the stimulus (unverifiable claims are marked [needs source] and submitted to memory/events/claims.ndjson via an authorized operation: propose request to registry-events.pyoffer-claims-registry is the sole adjudicator), or compute the TALE profile result (only the narrative-quality-auditor gate scores TALE). It works one lever — test design — and hands off.

Quick Start

Design a message-market-fit panel test for [tagline / one-liner]. Target panel: [role / segment]. Variants: [list or "single"].

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
