The Sequence Doctor
Diagnose a full sequence and rewrite the worst emails
$ npx skills add sidchaudhary/gtm-skills/skills/sdr/the-sequence-doctorWhat it does
Audits a full cold email sequence, diagnoses each email's weakness, and rewrites the three weakest.
You'll know it's time when...
A sequence has been running for weeks with low reply rates, and no one has audited which step is broken.
How it works
Run it in three steps
Install
Copy the install command above and run it in your project.
Ask Claude
Ask for what you need in plain English, no prompt tuning required.
Get the output
Claude returns a structured artifact aligned to your ICP and voice.
The Sequence Doctor
Audit a cold email sequence and return a structured diagnosis with rewrites for the weakest emails.
How to run
Ask the user for:
- The full text of every email in the sequence, with the send day for each (subject line + body)
- Their product description in one sentence
- Their ICP (company size, industry, core pain point)
- The persona they are targeting (job title, what they care about)
- Their top 2-3 competitors (optional but improves differentiation analysis)
- Reply rate per email if they have it (optional; helps prioritize the audit)
Output format
Output 1: Gap analysis
One paragraph per email. For each, identify the specific structural problem using one of these diagnoses:
- Vague value prop (what you do is unclear after reading)
- Wrong timing (this email lands too early or too late in the sequence)
- No specific hook (nothing in the opening connects to the prospect's situation)
- Too long (cut to what matters)
- Weak or unclear CTA (the ask is vague or asks for too much)
- Subject line mismatch (subject line creates an expectation the body does not fulfill)
- Feature focus (describes the product, not the outcome the prospect cares about)
Explain why each problem reduces reply rates. Be direct.
Output 2: Rewrites
Identify the three weakest emails. Rewrite each one in full. Keep the send day and sequence position the same. Fix the structural problem. Do not just polish the original wording.
Output 3: Missing step
Review the sequence as a whole. Recommend any follow-up type that is missing:
- LinkedIn touch between emails
- Breakup email at the end
- Re-engagement trigger after a specific action (opened three times, clicked a link)
- Phone step
- Video message
If a step is missing, recommend it with the suggested send day and one sentence on what it should say.
Quality check before returning
Before returning the output, verify:
- Does every email in the gap analysis get one of the seven named diagnoses, not a vague "this could be better"?
- Are exactly three emails identified as weakest and rewritten in full, with the same send day and sequence position preserved?
- Do the rewrites fix the structural problem identified, not just polish the original wording?
- Does the missing-step recommendation include a suggested send day and one sentence on what it should say?
If any check fails, fix the relevant output before returning. Do not return a draft that fails a check.

This is one of 12 SDR skills. They chain - the order you run them in changes what you get, and running one in isolation usually means re-answering setup another skill already captured. 12 best Claude Code skills for SDRs walks the whole pack in the order the skills actually chain.
Two ways to run it.
Pick your Claude surface. Both paths take under a minute.
npx skills add sidchaudhary/gtm-skills installs the whole set via the community skills CLI. If you'd rather not run a third-party CLI, use either path below to install the ZIP directly.- Open Settings, then Capabilities

Questions about The Sequence Doctor
Everything you need before installing, plus how the skill actually behaves once Claude picks it up.
Audits a full cold email sequence, diagnoses each email's weakness, and rewrites the three weakest. It's a Claude Agent Skill - a folder with a SKILL.md file and reference material - so Claude loads the methodology on demand when you ask for what you need in plain language, instead of you pasting a template.
