Top 10 best sales and GTM skills for Claude and Codex in 2026

I have been using Claude Code a lot lately for sales work, and I keep hitting the same wall.

It reasons through tasks well, but it remembers nothing about how I work. Every account brief, recap, and outreach draft comes out generic, and I end up re-explaining my ICP and templates every few days.

Skills fix this. A skill is a SKILL.md file that Claude Code loads on its own. It keeps your format, standards, and context, so the same request produces the same output every time.

The problem is that most GTM skill bundles are poorly maintained or never trigger. I tested the popular ones and kept what worked.

Best Sales Skills and Plugins for Claude Code and Codex

In Summary

The right skill depends on the sales job you want the agent to handle. If you need Claude or Codex to work inside actual apps, start with Composio. If you want one general GTM command, use sales-skills/sales. For outbound, enrichment, call follow-ups, transcript review, community listening, or post-sale handoffs, pick the narrow skill that matches that workflow.

What are Skills?

Skills are reusable instruction packs that tell an agent how to perform a specific workflow. Instead of rewriting the same prompt every time, you put the process, format, rules, examples, and guardrails into a SKILL.md file.

For sales work, that means Claude or Codex can remember how you want account briefs written, how call notes should be summarised, what your ICP looks like, and what tone to use in outbound drafts.

Claude Skills and Codex Skills operate similarly. Each skill usually lives in its own folder, with a SKILL.md file that includes a name, description, and task instructions. The description matters because it helps the agent decide when to load the skill. Once triggered, the agent reads the full instructions and follows that workflow.

In practice, skills are useful because they make agent output more consistent. A good sales skill can turn a vague request like “prep this account” into a structured brief with company context, stakeholders, pain points, objections, next steps, and outreach angles.

The simplest way to think about it:

• Prompts are one-off instructions.

• Claude Skills and Codex Skills are reusable workflows.

• MCP tools give the agent access to apps and data.

• Skills + MCP let the agent follow your process while working inside your actual sales stack.

For this list, I focused on skills and plugins that have a real install path, a clear sales use case, and enough structure to trigger reliably.

1. Composio: Connect HubSpot, Salesforce, Gong, and 1000 more apps in 2 minutes

For any serious tasks, you need agents to communicate with your apps. For example, pulling leads from HubSpot, creating email campaigns in Mailchimp, updates on Slack, etc.

Composio MCP with skill is the only setup in which Claude or Codex can reliably and securely access your company records at any given moment. And honestly, it has saved me countless hours of back-and-forth between multiple apps for routine tasks.

It honestly is super easy.

Composio also boasts the highest number of API actions across enterprise apps such as Salesforce, Gong, HubSpot, Outlook, and Google Sheets. This gives your agents the ability to work across your stack with zero hassles.

• Sends Gmail or Outlook messages from the Claude/Codex app.

• Post Slack, Discord, or Teams updates after a call

• Writes pages into Notion and rows into Sheets or Airtable

• Supports dry-run execution for safer first tests

• It can handle a huge amount of data from apps without extra engineering work

• Zero maintenance for all the apps. Just plug and play.

2. sales-skills/sales: A router-first Claude sales pack with hundreds of GTM playbooks

A Claude-oriented repo built around one router, /sales-do, plus a long catalog of sales and marketing skills. I would start here if the team wants one install and one entry point, because remembering 40 skill names is exactly the sort of overhead that kills adoption.

• Routes plain-English GTM asks through /sales-do

• Generates cold outbound sequences from a segment or ICP

• Handles CRM, enrichment, note-taking, and social-listening jobs

• Covers webinar, influencer, email, ad, and directory workflows

• Installs with one command, then triggers after restart

Install the router skill

npx skills add sales-skills/sales --skill sales-do

Restart and invoke it

/sales-do build a stakeholder map and 3-touch outbound sequence for CFOs at Series C fintech companies

3. ColdIQ GTM Skills: outbound playbooks from real campaigns

Built by ColdIQ, an agency that runs outbound for clients. The skills come from real campaigns, not theory:

7 master skills, 52 sub-skills, 137 sales triggers, 34 email templates, and Clay enrichment workflows.

Each master skill routes your request to the right sub-skill.

• 137 sales triggers and 34 cold email templates

• Covers Clay enrichment, list building, and signal-based selling

• LinkedIn ads and organic content skills included

• Browsable directory at coldiq.com

installs a master skill

npx skills add https://github.com/sachacoldiq/ColdIQ-s-GTM-Skills --skill cold-email

Do not install everything. Follow this flow instead:

• SDR teams: take cold email and list building.

• Signal-led or founder-led teams: take signal-based selling and the Clay skill.

• Paid-led teams: take the LinkedIn skills.

Using two or three skills is enough.

4. Vibe Prospecting plugin: live data for lead enrichment

Skills need data. This plugin gives Claude Code and Codex live access to 150M+ companies and 800M+ contacts from Explorium, so the agent looks up titles and emails instead of guessing them.

• Builds prospect lists from ICP filters

• Fills missing emails, phones, and titles in CRM records

• Handles ABM lists, lead scoring, and CSV cleaning

• Shows a preview and cost estimate before any fetch

Install and log in

npx @vibeprospecting/vpai@latest login

Run a first list build

build a list of VP Sales at US SaaS companies, 100–500 employees, that raised in the last 12 months — preview 5 rows first

Benefit: You see five sample rows and a cost estimate before anything is fetched, so a bad filter costs nothing.

Skill page: vibeprospecting.ai/product/plugin

5. Goose Skills: A cross-agent GTM catalogue with 108 skills and one install path

Gooseworks built one of the cleaner mixed-agent catalogs I found. If a team has Claude Code on one laptop and Codex on another, this is easier to live with than maintaining separate repos and separate instructions. It sounds boring. It is. That is why it works.

• Installs to Claude Code, Codex, Cursor, or all detected agents

• Adds access to a catalog of 108 GTM skills

• Covers sales, marketing, SEO, lead gen, and competitive intel

• Let users call a skill by name after install

• Supports updates through the same Gooseworks CLI

Install for Claude

npx gooseworks install --claude

Install for Codex

npx gooseworks install --codex

Update the catalogue

npx gooseworks update

6. AI Marketing Skills: Workflow-heavy Claude skills for pipeline, outbound, and growth ops

Eric Siu’s repo is closer to an operating kit than a prompt pack. The useful part is that the folders are opinionated about outputs: pipeline recovery, outbound optimisation, scorecards, and quote mining. A marketplace-sized bundle usually loses here because reviews get sloppy and trigger quality drops.

• Runs Deal Resurrector and Trigger Prospector sales workflows

• Includes Cold Outbound Optimizer and Lead Pipeline tools

• Adds Weekly Scorecard and experiment workflows for growth teams

• Ships category-level SKILL.md files for Claude Code use

• Supports scripts, scoring logic, and env-based automation

Clone the repo

git clone https://github.com/ericosiu/ai-marketing-skills.git

cd ai-marketing-skills

Copy one category skill into Claude

cp sales-pipeline/SKILL.md .claude/skills/sales-pipeline.md

Run a workflow example

cd growth-engine

pip install -r requirements.txt

cp .env.example .env

7. meeting-notes-and-actions: A Codex skill for turning rough call notes into clean follow-up

ComposioHQ’s Codex registry includes this narrow meeting skill, and I would take that narrowness over a giant bundle every time for post-call work. It misses broader account planning. Fine. The win is that reps get one recap shape to review before anything goes to a customer.

• Turns past notes into customer follow-up drafts

• Creates internal recap bullets for Slack or docs

• Builds next-step checklists with owners and deadlines

• Installs into ~/.codex/skills through the Codex installer

• Relies on Codex auto-triggering from skill descriptions

Install from the Codex registry

python ~/.codex/skills/.system/skill-installer/scripts/install-skill-from-github.py --repo ComposioHQ/awesome-codex-skills --path meeting-notes-and-actions

manual install fallback

git clone https://github.com/ComposioHQ/awesome-codex-skills.git

cp -R awesome-codex-skills/meeting-notes-and-actions ~/.codex/skills/

8. meeting-insights-analyzer: Transcript analysis for recurring objections, risks, and ownership gaps

This Codex skill is for teams drowning in transcripts. Generic summarizers flatten everything into the same bland recap.

The transcript analyzer skill within the skill pack earns its place when you need the repeatable stuff, recurring objections, risk patterns, and missing owners before a manager review or forecast call.

• Pulls themes and follow-ups from transcript files

• Flags call risks and behavioural patterns

• Extracts objection clusters for coaching or messaging

• Runs inside the Codex skill system, no separate app required

• Works on exported notes or pasted transcript text

Install the skill

python ~/.codex/skills/.system/skill-installer/scripts/install-skill-from-github.py --repo ComposioHQ/awesome-codex-skills --path meeting-insights-analyzer

Check that Codex can see it

ls ~/.codex/skills/meeting-insights-analyzer

head ~/.codex/skills/meeting-insights-analyzer/SKILL.md

9. sales-communitytracker: Public-community listening for buyer intent and competitor mentions

This one is a specialised skill pack.

CommunityTracker is for founder-led sales, product-led motions, and scrappier teams that pull demand from public conversations instead of waiting on form fills.

I was sceptical at first. Then I looked at how many real GTM teams are already mining Reddit, LinkedIn, X, and Slack for intent.

• Tracks mentions across Reddit, Slack, Discord, LinkedIn, X, GitHub, and HN

• Surfaces intent-scoring and share-of-voice workflows

• Feeds public discussion into prospecting research

• Lives inside the broader sales-skills/sales install

• Invokes well through the /sales-do router

Install the parent bundle

npx skills add sales-skills/sales --skill sales-do

Route a listening task

/sales-do find high-intent buyer signals for payroll software across Reddit, LinkedIn, and founder communities

10. issue-triage / linear: Post-sale handoff skills for turning friction into tracked product work

I am keeping these paired because the job is one path: transcript or pilot feedback, then triage, then a tracked issue.

This is for post-sale, pilots, and expansion motions, not cold prospecting. If customer pain keeps dying in Slack threads, this pair fixes a real leak.

• Triages Linear or Jira backlogs from the terminal

• Creates and manages Linear issues and workflows

• Turns escalation notes into tracked product follow-up

• Pairs well with transcript and meeting-note skills

• Helps account teams close the loop after pilots

install issue triage

python ~/.codex/skills/.system/skill-installer/scripts/install-skill-from-github.py --repo ComposioHQ/awesome-codex-skills --path issue-triage

Install the Linear skill

python ~/.codex/skills/.system/skill-installer/scripts/install-skill-from-github.py --repo ComposioHQ/awesome-codex-skills --path linear

Also worth a look ( bonus)

Two repos with skills and plugins almost made the list, but with a few caveats

• Extruct's gtm-skills and gtm-cowork-skills cover outbound and deal execution well, but the prompts assume their stack (Granola transcripts, MEDDPICC, and Attio) needs editing before they fit your workflow.

• The Claude GTM Plugin is the largest bundle around and has a useful /bootstrap interview, but it leans more toward marketing than sales. If your motion fits, both are solid.

Write a CLAUDE.md for sales

One habit I always enforce on everyone on my team is to put a CLAUDE.md in the project root. It should only contain:

• ICP,

• deal stages,

• methodology,

• tone rules,

• and guardrails like "never send without review."

This makes the skills read it before they run, so everything comes out in the desired voice. A simple ten-minute hack, and with this, every install above gets better.

Wrap up

A few practical caveats before I wrap:

• Do not install all ten skills at once. This trigger’s quality lives in each skill's description field. In fact, Anthropic's skills guidance identifies under-triggering and over-triggering as the most common failures. Read the SKILL.md instructions before you trust the install.

• Watch overlap. ColdIQ, Goose, and the router pack each ship a cold email skill. Keep one and remove the rest, or they compete for the same trigger.

• Be careful with write access. Once an agent can touch Gmail, Slack, or Linear, you are testing live operations, not drafts. Use dry runs and connect the fewest apps.

• Best to use Composio as an orchestration layer for secure auth, optimised tool calls, and parallel processing.

My blunt recommendation is simple: start with one router, one meeting skill, and one app-action bridge. If you install five overlapping bundles, you will spend next week debugging triggers instead of moving deals.
