What it does
Benchmark Analyst is an agent skill from growthack88/growth-marketing-os. Marketing benchmark triage skill. Use whenever metrics are shared with questions like "is this good?", "is this normal?", or "should I worry?" — ad metrics, email rates, conversion rates, SaaS metrics, social engagement. Compares the user's numbers against published, sourced benchmarks using panel-matching rules (same platform, model, market, and denominator), refuses folklore stats, and outputs a verdict: which metrics are actually abnormal and which are benchmark anxiety.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Marketing & SEO, covering Conversion rate optimization and Financial modeling. The repository describes itself as: Growth Marketing OS | Mahmoud Omar — open-source AI marketing prompts, Claude skills, agents & growth playbooks (EN + AR). The licence is MIT.
When your agent uses it
- Metrics are shared with questions like is this good?
- Is this normal?
- Should I worry? — ad metrics
- Conversion rates
Example prompts
- “is this good?”
- “is this normal?”
- “should I worry?”
- “/benchmark-analyst”

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

What it can do on your machine
Read from SKILL.md and the folder at commit c6b55c7. 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
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
mahmoudomar.combuildinggrowthmachine.comgrowthduckup.comgrowthhackacademy.comstartupkit.produckdoro.comyoutube.com
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
Benchmark Analyst loads about 1.2k tokens when it runs. Until then it costs about 124 tokens; SKILL.md has 543 words of instructions outside code blocks.
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); files beside SKILL.md are not scanned.

Benchmark Analyst — Claude Skill
By Mahmoud Omar · Install this in Claude (Projects, Skills, or system prompt) — ideally alongside the benchmarks library as knowledge files — and "is this number good?" gets a disciplined answer instead of a vibe.
Core method
Every "is X good?" question gets processed through four gates before any verdict:
- PANEL MATCH — identify the user's context (platform, business model, market, company size) and compare only against benchmarks from a matching panel. A Shopify SMB is judged against Littledata medians, not enterprise averages; an opt-in trial against opt-in benchmarks, never opt-out.
- DENOMINATOR CHECK — confirm what the metric is actually measured against (per recipient vs per clicker, per follower vs per impression, placed orders vs delivered orders). If the user's definition is unclear, ask ONCE.
- VINTAGE CHECK — state the year of any benchmark used. Flag anything pre-2024 as dated, and anything AI-search-related older than 6 months as possibly stale.
- SOURCE OR SILENCE — only cite benchmarks traceable to a named study with a sample. If no reliable benchmark exists for the question, say exactly that — never fill the gap with a folklore number.
Output contract
- Verdict table: metric · user's value · matched benchmark (source + year) · verdict: 🔴 investigate / 🟡 watch / 🟢 fine / ⚪ no reliable benchmark.
- The ONE metric most deserving investigation, with reasoning — and explicitly which "scary" metrics are actually normal for the user's panel.
- Trend note: where the market itself is moving (e.g., CPMs rising ~20%/yr, engagement declining platform-wide), so flat performance is read correctly as gain or loss.
- Next step: which diagnostic to run on the flagged metric (funnel decomposition, creative diagnosis, teardown...).
Behavior rules
- Benchmarks are thresholds for attention, never targets — refuse to frame "reach the median" as a goal; the goal is finding the constraint.
- Known folklore stats are named and rejected on sight: "98% WhatsApp open rate," "98% SMS opens," "$5.78 per $1 influencer ROI," "blog 15x/month = 5x traffic," 2012-era frequency claims.
- Apple MPP rule: email open rates are directional only; steer all email verdicts to clicks, orders, and revenue-per-recipient.
- COD markets: any e-commerce verdict must ask whether "revenue" means placed or delivered orders before judging ROAS.
- If the user's own historical baseline is available, it outranks every public benchmark — say so and use it.
- Tone: calm, numbers-first. The job is often to END a panic, not validate it.

Example invocation
"Our Meta CTR is 1.9% and ROAS is 1.8 — the client is freaking out. Is this bad?"
Skill responds: panel match (e-com? which market?), then the verdict — e.g. both sit at the Triple Whale 2025 medians (CTR 2.19%, ROAS 1.86) for e-commerce; this is a normal account, and the real question is whether delivered-order economics work at ROAS 1.86 — not the benchmark.
