Email campaign/sequence performance review composite. An agent skill from majiayu000/claude-skill-registry.

  • Works in 7 steps: Intake → Pull Campaign Data → Quantitative Analysis → …
  • Tasks that involve GraphQL
  • SKILL.md covers When to Use, Phase 0: Intake, Step 1: Pull Campaign Data and Step 2: Quantitative Analysis, plus 4 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Sequence Performance is an agent skill from majiayu000/claude-skill-registry. Email campaign/sequence performance review composite. Pulls campaign data (sends, opens, replies, bounces), reads actual email copy and subject lines, analyzes reply content (objections, positive interest, questions), and produces a diagnostic report covering quantitative metrics, copy quality, lead quality, and actionable recommendations. Tool-agnostic — works with Smartlead (MCP), Instantly, Outreach, Lemlist, Apollo, or CSV data.

Its SKILL.md is about 3.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `metadata.json`).

It sits in Business, Finance & HR, covering GraphQL, Email marketing and Performance reviews. It works with Model Context Protocol. The repository describes itself as: Searchable Claude Code skills catalog with source-linked guides and generated registry artifacts. The licence is MIT.

When your agent uses it

  • Tasks that involve GraphQL
  • Tasks that involve Email marketing
  • Tasks that involve Performance reviews

Example prompts

  • “/sequence-performance”

Workflow steps

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

  1. Intake
  2. Pull Campaign Data
  3. Quantitative Analysis
  4. Reply Analysis
  5. Copy Quality Assessment
  6. Lead Quality Assessment
  7. Generate Report

What it can do on your machine

Read from SKILL.md and the folder at commit 2d14a69. 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

    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

Sequence Performance loads about 3.3k tokens when it runs. Until then it costs about 114 tokens; SKILL.md has 1,313 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~114
When it runs · the whole SKILL.md, loaded when a task matches
~3.3k

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.

Sequence Performance

Goes beyond vanity metrics. Most campaign reports tell you open rate and reply rate. This skill reads the actual emails you sent, reads every reply you received, classifies the responses, evaluates your copy, evaluates your lead quality, and tells you specifically what's working, what's not, and what to do about it.

Three layers of analysis:

  1. Quantitative: The numbers — sends, opens, replies, bounces, conversions, by touch and by variant
  2. Qualitative (Copy): Are the subject lines, email bodies, CTAs, and personalization actually good?
  3. Qualitative (Replies): What are people actually saying? What objections keep coming up?

When to Use

Use this skill when:

  • User says "how's my campaign doing", "sequence performance", "campaign review", "email analytics"
  • User says "analyze my outreach", "why isn't my campaign working", "review my email results"
  • A campaign has been running for 7+ days and has meaningful data

Phase 0: Intake

Outreach Tool
  1. What outreach tool do you use? (Smartlead / Instantly / Outreach.io / Lemlist / Apollo / Other)
  2. How do we access campaign data? (MCP tools / API / CSV export / paste metrics)
Campaign Selection
  1. Which campaign? (name or ID)
  2. Date range? (or "all data")
Your Company Context (for copy evaluation)
  1. What does your company do? (one-liner)
  2. Who is your ICP? (titles, industries, company size)
  3. What problem do you solve?
  4. What's your CTA goal? (book meeting, get reply, drive to page)
Benchmark Context
  1. Is this cold outreach or warm/nurture?
  2. What segment are you selling to? (SMB, mid-market, enterprise)

Step 1: Pull Campaign Data

Pull three categories of data from the user's outreach tool:

A) Campaign Metrics
Data PointWhat We Need
Total emails sentBy touch (Touch 1, Touch 2, Touch 3, etc.)
Total unique recipientsDeduplicated count
OpensBy touch, unique opens vs. total opens
RepliesBy touch, total reply count
BouncesHard bounces + soft bounces
UnsubscribesCount
ClicksIf link tracking is on
Positive repliesIf categorized in the tool
Meetings bookedIf tracked

How to pull by tool:

ToolMethod
Smartlead (MCP)mcp__smartlead__get_campaign_stats, mcp__smartlead__get_campaign_sequence_analytics, mcp__smartlead__get_campaign_variant_statistics
Instantly / Outreach / Lemlist / ApolloAsk user for CSV export or paste metrics
OtherUser provides CSV with columns: email, status, opened, replied, bounced
B) Email Copy (Sequence Content)

Pull the actual templates for every touch:

ToolMethod
Smartlead (MCP)mcp__smartlead__get_campaign_sequences
OthersUser pastes the copy or provides CSV export
C) Reply Content

Pull the actual text of every reply:

ToolMethod
Smartlead (MCP)mcp__smartlead__get_campaign_leads_history, mcp__smartlead__fetch_master_inbox_replies
OthersUser provides reply dump or CSV export
Human Checkpoint
Campaign: [name]
Status: [active/paused/completed]
Sent: X emails to Y recipients
Replies: Z (full text pulled for analysis)
Touches: N touches, M variants

Data looks complete? (Y/n)

Step 2: Quantitative Analysis

Benchmarks
MetricCold (SMB)Cold (Mid-Market)Cold (Enterprise)Warm/Nurture
Open rate40-60%30-50%25-40%50-70%
Reply rate3-8%2-5%1-3%10-20%
Positive reply rate1-3%0.5-2%0.3-1%5-10%
Bounce rate<3%<3%<2%<1%
Unsubscribe rate<1%<1%<0.5%<0.5%
Calculate

Overall metrics: open rate, reply rate, positive reply rate, bounce rate, unsubscribe rate, deliverability rate. Compare each to the benchmark.

Per-touch breakdown:

  • Touch-level open/reply rates
  • Marginal reply rate (replies from THIS touch / people who received this touch but hadn't replied yet)
  • Touch contribution (what % of total replies came from each touch)

Variant analysis (if A/B testing):

  • Open rate and reply rate per variant
  • Statistical confidence: <50 sends = "insufficient data", 50-100 = "directional", 100-250 = "likely winner", 250+ = "statistically significant"
  • Winner recommendation: scale, keep testing, or kill

Step 3: Reply Analysis

Read every reply, classify it, and extract patterns.

Reply Categories
CategoryDefinition
Positive interestWants to learn more, open to a conversation
Meeting requestExplicitly asks to meet or provides availability
Warm / CuriousInterested but non-committal, asks questions
Objection — TimingNot now, but potentially later
Objection — BudgetCan't afford or not a priority
Objection — CompetitorAlready using a competing solution
Objection — RelevanceDoesn't see the fit
Objection — AuthorityNot the right person
Not interestedFlat no
Auto-reply / OOOAutomated response
ReferralRedirects to someone else
QuestionAsks about product/offering
Objection Patterns
  • Which objection appears most? (reveals systemic issues)
  • Do objections cluster at Touch 1 (bad targeting) vs. Touch 3 (fatigue)?
  • Which are handleable (timing, authority) vs. terminal (relevance)?
  • What exact language do people use?
Positive Signal Patterns
  • Which touch/variant generated positive replies?
  • What do positive responders have in common? (title, industry, company size)
  • What questions do warm leads ask? (reveals what's missing from the email)
Reply Quality Score
ScoreCriteria
Strong>50% positive/warm. Objections are handleable.
Mixed30-50% positive. Mix of handleable and terminal.
Weak<30% positive. Dominated by "not interested" and "not relevant."
ToxicHigh unsubscribe + angry replies. Something is fundamentally wrong.

Step 4: Copy Quality Assessment

Evaluate the actual email copy against best practices and reply data.

Subject Lines
CriterionRed Flags
Length>60 chars gets truncated on mobile
SpecificityGeneric "Quick question" or "Checking in"
Spam triggers"Free", "Limited time", ALL CAPS
Open rate correlationLow open rate = subject line problem
Show full SKILL.md (523 more words)Show less
Email Body
CriterionRed Flags
Hook (first line)"I'm reaching out because..." or "We are a company that..."
LengthOver 150 words
Value prop clarityJargon, vague language, buzzwords
Proof pointsNo proof = no credibility
PersonalizationOnly {first_name} merge field
CTAMultiple CTAs, high-friction asks, or no CTA
Filler language"Hope this finds you well", "just checking in"
Sequence progressionTouch 2 is just a "bump" of Touch 1
Grades

Grade each touch A through F on: hook quality, value prop clarity, proof usage, personalization level, CTA quality.

Step 5: Lead Quality Assessment

Evaluate whether we're sending to the right people.

Targeting Check
  • Do lead titles match ICP buyer/champion/user personas?
  • Are leads in target industries?
  • Right seniority level for the ask?
  • Company size in target range?
Signal Quality (from replies)
PatternWhat It Tells You
High "not relevant" repliesSending to people who don't have the problem
High "wrong person" repliesRight companies, wrong roles
High "already have a solution"Right problem, late to the party
High "timing" objectionsRight people, right problem, wrong moment — not a targeting issue
Low reply + high open ratePeople open but don't find it relevant — copy/targeting mismatch
High bounce rateList quality issue — bad emails, old data

Adapting to Data Availability

Missing DataWhat Gets SkippedStill Useful?
Reply textReply classification + objection patternsPartially — metrics + copy still run
Variant dataVariant analysisYes — single-variant analysis still runs
Lead demographicsTargeting assessmentYes — infers from reply patterns
Open trackingOpen rate analysisPartially — reply rate + copy still run

Minimum viable data: Emails sent + reply count + email copy text.

Cost

Free. Pure reasoning + data from user's outreach tool.

Tips

  • Run at Day 7 and Day 14. Day 7 catches deliverability and subject line problems. Day 14 gives enough replies for objection analysis.
  • Reply analysis is where the gold is. Metrics tell you WHAT. Replies tell you WHY.
  • High open + low reply = copy problem. The subject gets them to open but the email doesn't deliver.
  • Low open + decent reply rate = subject line problem. The email works, people just aren't seeing it.
  • "Not relevant" is the most important objection. If >20% say "this isn't for me," it's targeting, not copy.
  • Don't kill a variant too early. Need 100+ sends per variant for directional data.
  • Touch 2/3 should contribute 30-40% of replies. If Touch 1 is 90%+, your follow-ups aren't adding value.
