Claude Skills

The open format is called Agent Skills and works in Claude Code, Codex, Cursor and other agents — most people know it as Claude Skills.

Every Agent Skill we could find on GitHub, deduplicated by content. 80 149 files from 1 774 authors, of which 62 489 are unique — the rest is the same skill repackaged into someone else's repository. For each one: what it weighs in tokens, whether it ships runnable scripts, and which MCP servers it needs.

Gtm Signal Sweep
by markfulton

Weekdays, heavy browser lane. Reads the member's own signal sources and saved searches, captures dated buying signals together with the contactable people attached to them, and appends both to the ledgers the outreach queue reads. Read only on every people surface, LinkedIn included. It holds every outbound action unless you released the channel, and it never touches a credential.

Gtm Paid And Tracking Guard
by markfulton

Weekly. Audits the paid and measurement setup the member already has by reading it, then assembles the parts that are missing as local files: campaign structure, ad copy, negative keyword seeds, and conversion tracking specifications, each one complete and ready to paste. It creates nothing in an account, saves nothing, activates nothing, and spends nothing, unless you released the channel. This is where the spend stop lives.

Sales Desk Standup
by markfulton

Weekdays, file work only, no browser at all. Reads every ledger, queue file, and run record written since its own cursors, turns the member's ticks into sent rows and closed cards, folds the card inbox, re-renders the pipeline board, and writes the short morning brief the member opens first. It names the veto window every day. It holds every outbound action unless you released the channel, and it never touches a credential.

20k tokens
Sales Desk Setup
by markfulton

Runs once by hand on the first day and once a month after that, on the first weekday, light browser lane. On the first run it researches the business from its own public surfaces before asking anything, writes the strategy folder, seeds the pipeline, reconciles the schedule table, and registers the recurring jobs. On every monthly run it re-reads the evidence the kit produced, applies what changed to the files it owns, and carries every member written setting across verbatim. It holds every outbound action unless you released the channel, and it never enters a credential.

Sales First Touch Drafts
by markfulton

Weekdays, heavy browser lane. Selects the qualified people who have never been written to, drafts each one a first touch into a dated queue file the member reads, and composes each passing draft into the member's own mailbox as an unsent draft. It verifies by the Drafts count and never by a toast. It holds every outbound action unless you released the channel, and it never touches a credential.

18k tokens
Sales Followup Sweep
by markfulton

Weekdays, heavy browser lane, two halves in one run. First it reads the member's own mailbox for replies on the threads the ledger says were sent and records them. Only then does it work out who is due a follow up, write each one into a dated queue file, and compose it into the mailbox as an unsent draft. It holds every outbound action unless you released the channel, and it never touches a credential.

Sales Pipeline Review
by markfulton

Weekly, on a Friday, read only everywhere. Scores the week from the ledgers with a source path beside every number, replays the browser flows the other routines depend on, names one thing to kill and one thing to scale, and files both as cards. It sends only where you released the channel, spends only where you released it, never touches a credential, and never writes a number it did not count out of a named file this run.

19k tokens
Sales Prospect Sweep
by markfulton

Weekdays, heavy browser lane. Reads the member's own saved searches and the named sources for one buyer segment, captures candidate accounts together with the contactable people attached to them, scores every row against the named tests in the qualification file, and writes each one with the evidence that qualified it. Read only on every people surface, LinkedIn included. It holds every outbound action unless you released the channel, and it never touches a credential.

SEO Answer Visibility

Observe answer visibility for approved buyer questions, audit discoverability and file evidence-backed improvement cards.

SEO Calendar Refill
by markfulton

Weekly, browser only when a source refuses to be fetched. Counts unpublished calendar entries per property by folding the published ledger against the calendar, and where every property is above its runway threshold it records the counts and exits, which is the normal run. Where a property is low it researches the next block from rank evidence, the topic map, and live result sets, refuses any keyword already targeted, and appends fully specified entries after the last existing block. It is the only writer of the calendar and it never modifies, reorders, or renumbers an existing entry.

15k tokens
Sales Qualification Refresh
by markfulton

Monthly, on the last weekday, light browser lane. Re-tests every named qualification test and every buyer segment against a month of this kit's own ledger evidence, then rewrites both files itself where the evidence disagrees with the assumption they were written on. It records every change in strategy/CHANGELOG.md with the ledger path that justified it. It sends only where you released the channel, never re-queues anyone, never edits the contacted ledger, and never writes a number it did not count out of a named file.

19k tokens
SEO Draft Run
by markfulton

Weekdays, browser only when a source refuses to be fetched. Works the single card the standup marked next: reads the shared publishing standard and the card's specification, pulls the live result set for the primary keyword, reads the pages currently ranking, writes the body, the metadata, the internal links and the outbound authority links, generates and compresses a hero, and leaves a complete draft folder with one ready line. It never opens a publishing surface, never touches a live property, and never touches a credential.

18k tokens
SEO Index Sweep
by markfulton

Weekly, browser heavy. Unions every sitemap each property declares without a browser, builds the candidate set from URLs not already in the indexing ledger, then drives the member's own search performance console to inspect each candidate and request indexing inside an account wide allowance. Spends what is left on sitemap health, which is unmetered. It inspects, requests, and views or submits sitemaps inside that console and does nothing else there, ever, and it never removes a sitemap.

15k tokens
SEO Rank Review
by markfulton

Weekly, browser heavy, read only on every screen. Fixes a scoring window that neither double counts nor loses an hour, reads the member's search performance console and analytics property, verifies each range actually applied before reading a figure, reconciles every number against what this Employee published, writes the week's scoreboard and the short rolling state file every other routine reads, and files what it found as cards rather than doing the work itself. It types nothing on any screen, changes no setting, publishes nothing, and never touches a credential.

19k tokens
SEO Publish Run
by markfulton

Weekdays, browser only when the property has no publishing route but a screen. Takes the oldest ready draft, resolves its property, and publishes it by that property's own route: a post file plus a registry entry plus a sitemap update plus a build plus a push, or a publishing surface driven through the flow file it owns. It verifies the live URL by loading it, records the published line, and leaves the draft ready on any failure so tomorrow retries it. It publishes one article to one named property and does nothing else outward, ever.

18k tokens
SEO Intake And Map
by markfulton

Monthly, browser conditional. On its first run it discovers the member's properties from the sites they name, writes the three strategy files, creates every ledger and folder the kit reads, files the opening cards, and registers the eight scheduled jobs. Every month after that it re-reads the evidence rather than its own previous conclusions, rebuilds the topic map and the internal link map, corrects any property fact it can prove wrong, and records every change with the path of the evidence that forced it. It holds publishing and spending unless you released the channel, and it never touches a credential.

24k tokens
SEO Standup
by markfulton

Weekdays, file work only, no browser at all. Reads every run record since it last ran, folds the published, draft, indexing, and rank ledgers, folds the card inbox into the work board, marks the single card the draft run works today, and writes the short morning brief the member opens first. It holds publishing and spending unless you released the channel, and it never touches a credential.

20k tokens
Soc Calendar Standup
by markfulton

Weekdays, file work only, no browser at all. Reads every ledger, queue file, and run record, turns yesterday's ticks into facts a machine can count, folds the slot inbox, rewrites the content calendar, and writes the one short brief the member opens first. Its most important line names which slots publish today and how to stop them. It publishes only where you released the channel, never replies, spends only where you released it, and never touches a credential.

19k tokens
Soc Engagement Sweep
by markfulton

Weekdays, heavy browser lane. Opens the member's own signed in profile, post, and notification surfaces for every platform in the channel plan, confirms that everything published since the last run is genuinely live, reads the counts attached to each post, captures every comment, mention, quote, reply, and inbound message into a queue the member answers by hand, and drafts a suggested reply for each one. Read only everywhere and totally read only on LinkedIn. It sends only where you released the channel, never replies, spends only where you released it, and never touches a credential.

16k tokens
Soc Draft Queue
by markfulton

Weekdays, browser only where a link genuinely needs verifying. Writes tomorrow's slots, one draft per due slot per destination, from the voice file, the drafting standards, and the dated material captured this morning. It rotates the post framework so no skeleton repeats, enforces the plain text and character budget rules the platforms actually impose, and judges every candidate before it lands. It publishes only where you released the channel, never schedules, never replies, spends only where you released it, and never touches a credential.

17k tokens
Soc Intake And Voice
by markfulton

Runs once by hand on the first day and once a month after that. On the first run it researches the business from its own public surfaces, reads the member's own already published posts, and builds the voice file from real samples rather than from an idea of a voice, then writes the plan, creates the proof inventory, seeds the opening slots, and registers the recurring jobs. On every monthly run it re reads the evidence the kit produced and rebuilds only what the evidence contradicts. It publishes only where you released the channel, never replies, spends only where you released it, and it never enters a credential.

23k tokens
Soc Material Sweep
by markfulton

Weekdays, heavy browser lane. Captures the dated raw material tomorrow's drafts are built from, out of the member's own shipped work, their own site and changelog, their own signed in saved searches, and the places their audience already is. Every line carries a source URL read this run, a date, a verbatim quote, and an expiry. It invents nothing, it is read only everywhere and totally read only on LinkedIn, and it sends only where you released the channel, spends only where you released it, and never touches a credential.

17k tokens
Soc Performance Review
by markfulton

Weekly, on a Friday, read only everywhere. Scores the week from the kit's own ledgers with a source path beside every number, cuts it by platform, framework, pillar, slot time, and post length, rewrites the drafting standards from that evidence and from nothing else, replays the browser flows the other routines depend on, and files exactly one thing to stop and one to do more of. It publishes only where you released the channel, never replies, spends only where you released it, never touches a credential, and never writes a number it did not measure.

Web Guardrail Review
by markfulton

Monthly, file work only, no browser at all. Re-reads a month of real change outcomes and rewrites the file that decides what the fix runner may change without asking first. A class the member merged unchanged repeatedly widens by exactly one step. A class they edited, closed unmerged, or that regressed narrows immediately. It never touches the outer boundary, which no volume of evidence can widen.

13k tokens
Soc Publish Run
by markfulton

Weekdays, light browser lane. The one routine in this kit with an outward surface. Takes the slots that are due today, whose drafts were written yesterday and passed the copy check, whose hold box is not ticked, and whose destination the member wrote into the publish allow list themselves, and hands each one to the channel the member configured. It records a receipt the instant each slot lands. It never drives a browser control to publish, never replies, sends only where you released the channel a message, spends only where you released it, and never touches a credential.

Web Fix Runner
by markfulton

Weekdays. Takes the one card the standup marked next and turns it into a reviewable change on a branch, never a deployment. It reads the project's own rules and docs first, makes the smallest change the card describes, runs that project's own gate, writes a change brief with the rollback in one line, and pushes the branch for the member to merge. It never merges, never deploys, never applies a migration, and never rotates a key.

17k tokens
Web Dependency Run
by markfulton

Weekly. Works dependency and supply chain debt one project at a time, sorting every candidate into patch and lockfile only, minor, and anything major or breaking. It bumps the first class on a branch behind that project's own gate and pushes it for the member to merge. It holds the other two with a reason and a card carrying the evidence, so the member decides rather than being handed a red build.

14k tokens
Web Inventory Refresh
by markfulton

Monthly, and on its first run it is the whole setup, launched by hand. It discovers what the member actually runs by walking their code roots and reading the registrar, the host, and the hosted database, then writes the inventory, the domains file, the starting budgets, and the opening safe fix rules, seeds the board, builds the dashboard, and registers one scheduled job per routine. It creates no account, buys nothing, and provisions nothing.

17k tokens
Web Site Sweep
by markfulton

Weekdays. Checks every project in the inventory from the outside, records one dated observation per project, then reads the production log surfaces since its own cursor and groups every error into a fingerprint so a hundred sightings are one incident. It appends the health ledgers, writes the health digest, and cards the incidents that clear the threshold. It changes nothing, deploys nothing, and never rotates a key.

17k tokens
Web Platform Guard
by markfulton

Weekly. Confirms that the registrar, the host, and the hosted database still match what the inventory says, in one read only pass per project, and names every drift with the exact screen, the exact current value, and the exact intended value. It records that a variable exists and never its value, it fixes nothing inside an account, it buys nothing in any state, and it never rotates a key.

16k tokens
Web Standup
by markfulton

Weekdays, file work only, no browser at all. Reads every ledger and run record since its cursor, resolves which drafted changes actually merged by reading the commit graph rather than a dashboard, closes and reopens incidents on that evidence, folds the card inbox, re-renders the review board, and writes the short morning brief the member opens first. It never merges, never deploys, and never touches a credential.

Web Weekly Report
by markfulton

Weekly. Scores the week from the ledgers with a source path beside every number and never writes a number it did not count in a file this run. It names exactly two things and files both as cards, the one fix worth doing next week and the one thing to stop, and it replays every learned browser flow once, read only, so a drifted selector is found on a Friday rather than on a Tuesday morning a routine needed it.

Claude Skills — questions

Answers built from the skills we actually parsed.

What is a Claude Skill?
A folder with a SKILL.md file: instructions that teach an agent to do one thing well, optionally with scripts and reference files alongside. The format is open and called Agent Skills — Claude Code, Codex and other agents read the same files. It is not a program you run; it is knowledge the agent loads when the task calls for it.
How is a skill different from an MCP server?
A server gives the agent new abilities — it connects to something and exposes tools. A skill gives the agent knowledge: how to use what it already has. They combine, and often literally: 11 696 of the skills here declare which MCP servers they need to work.
Why are there fewer skills here than in other catalogues?
Because we deduplicate by content. Of 80 149 files found on GitHub, 62 489 are unique — the rest is the same skill copied into someone else's repository, word for word. Catalogues that count files rather than skills show every copy as a separate entry.
What does the token count mean?
A skill is loaded into the model's context when it is used, so its size is a running cost on every request that touches it. We measure the whole folder, not just SKILL.md: one official skill is 377 tokens, another drags 83 files of fonts behind it.
How do I install a skill?
Copy the skill folder into ~/.claude/skills for personal use, or into .claude/skills inside a project. The agent picks it up by the name in the SKILL.md header — which is worth checking: 7 984 skills here share a name with another skill, and two of them cannot sit side by side.
