What this is

A single dated compilation of the public counts for agent skills, with the source and the reading date beside every figure. Route: /agent-skills-by-the-numbers.

Every number was re-read at its source on September 2, 2026.

Figure Value Source
Products on the Agent Skills client showcase 46 agentskills.io/clients
Of those, products whose own docs state it 11 our own /agent-skills-support register, vendor docs read 2026-08-20
Skills on the public skills.sh directory 9,704 totalSkills in the skills.sh home page data
Most installed skill: find-skills 3,220,754 skills.sh home page data, top eight listed
Skills in anthropics/skills 19 git tree at commit 5304866
Bundled skills documented in Claude Code 15 code.claude.com commands reference, up from 13 on Aug 18
GitHub stars, obra/superpowers 280,721 GitHub REST API
GitHub stars, anthropics/skills 173,173 GitHub REST API
GitHub stars, vercel-labs/skills 30,228 GitHub REST API
GitHub stars, agentskills/agentskills 24,968 GitHub REST API

Seventeen datapoints in total, all in lib/seo/agent-skills-by-the-numbers/datapoints.ts.

What changed from the first draft

The first draft answered two questions at once. The title asked how adopted agent skills are; three of the figures measured this site rather than the format. Those are gone:

  • the AI crawler ratio and the whole crawler section
  • the organic impression series and the Search Console AI features report
  • the method steps describing our own instrumentation, and the log drain and Search Console sources
  • the unlabelled 1,297,018 that skills.sh prints beside its tab, which is not a skill count and moved to 1,297,019 between two readings

Added in their place: the per-skill install table, which is the strongest public adoption signal that exists for this format, plus star counts and the SEP-2640 status.

Hypothesis and metric

Nobody publishes a dated, sourced compilation of these counts. The bet is that being the one page that does makes it the thing an AI answer cites when somebody asks how many agent skills exist or how many products support them.

Metric: first impressions and citations at two to four weeks. Refresh is monthly and is an edit to one typed file, with a test asserting every datapoint renders exactly once and cites a source the page lists.

Honesty constraints held in tests

  • no figure without a source id and a reading date
  • install counts labelled as telemetry from one tool, with a paragraph on what they miss
  • stars labelled as attention, not adoption
  • a limits section naming the five questions the page does not answer
  • no em dash, no en dash, no "recommend", no "shared library"
  • Skills Board named once, as an apposition

Verification

  • tsc --noEmit: 0 errors
  • node --test tests/*.test.mjs: 582 passing, 0 failing
  • production build: clean, page prerendered
  • smoke: page 200, .md twin 200, Accept: text/markdown negotiation 200, trailing slash 308, old route 404 everywhere, sitemap and llms.txt on the new path only

…ide every figure

Nobody publishes a census of agent skills. This page collects the partial
counts that do exist and adds three we can measure ourselves: the AI crawler
split in our own server logs, the Search Console beta report on impressions
inside AI answers, and one small site's organic impression series.

Every figure lives in lib/seo/agent-skills-adoption/datapoints.ts with the
source id and the date it was read, so the monthly refresh is an edit to one
file. The page declares its own size and carries a limits section for the five
questions it cannot answer.

P2 Badge Derive refreshable copy from the datapoints

The documented monthly-refresh workflow updates only datapoints.ts, but this answer independently hardcodes the same values and dates; the description, FAQ, OG copy, source notes, modifiedAt, and public/llms.txt contain further copies. On the first refresh, the tables will show new datapoints while prominent prose and JSON-LD continue publishing the September figures and last-modified date. Build these strings and the page date from the datapoints, or make the refresh contract cover and validate every duplicate.

P2 Badge Preserve source IDs in rendered table rows

This conversion drops datapoint.sourceId, so neither the HTML nor Markdown table can identify the source for an individual figure. The later section-level source list is ambiguous when a section contains several datapoints and several sources—for example, the ecosystem section has four figures backed by three primary sources plus two supporting sources—despite the page promising one source beside every figure. Carry the source mapping into each rendered row rather than retaining it only in the unused datapoint record.

Correction pushed (e263deb). The earlier revision published the skills.sh leaderboard number 1,297,018 as a count of skills. It is not one: the all-time leaderboard's own page payload reports totalSkills: 9704 beside allTimeTotal: 1297018 (read 2026-09-02), and the docs API example shows pagination.total in the thousands, so the catalog is thousands of skills, not millions.
It is not a sum of installs either, which is the other reading that came up in review: the leaderboard's top skill, vercel-labs/skills/find-skills, reported 3,220,754 installs on the same day, more than the total itself. skills.sh attaches no unit to that number anywhere on the page or in its API reference.
The page now publishes 9,704 as the skill count (noting that the trending view reported 9,922 the same day) and keeps 1,297,018 only as the unlabelled total it is, so that nobody quotes it as a number of skills. Description, answer, method, FAQ, the "what none of this measures" section, the OG copy, and the llms.txt line all move with it.
Re-verified: tsc --noEmit 0 errors, 578/578 unit tests pass, next build succeeds, and the page smoke test returns 200 text/html with the Markdown twin 200 text/markdown.

Rewrite the intro and the answer-first summary so the first sentence is
the crawler ratio rather than three negations about what nobody counts.
The answer leads with the two contrasts (crawler ratio, impression
growth) before the ecosystem counts, all still dated. The first answer
note becomes a reading key instead of a second disclaimer; the limits
section is unchanged.

Rewrote the intro and the answer-first summary on founder feedback: the page now opens on the strongest checkable figure (AI crawlers reading this site 5.9x more often than Googlebot and bingbot combined) instead of three negations and a disclaimer.

The answer snippet leads with the two contrasts (crawler ratio, 98 to 3,919 impressions July to August 2026) before the ecosystem counts, all still dated. The first answer note is now a reading key rather than a second disclaimer; the site size stays declared once, and the limits/FAQ/method sections and datapoints.ts are untouched. Typecheck clean, 578 tests green, production build plus twin .md smoke checked.

…the-numbers

The headline question was how adopted agent skills are, and three of the
figures answered a different one. The AI crawler ratio, the organic
impression series, and the Search Console AI report all measured this site,
not the format, so they are removed along with their sources, their method
steps, and the copy that leaned on them.

What is left is one coherent page of public counts, each re-read at its
source on September 2, 2026: 46 products on the client showcase and the 11
whose own documentation states it, 9,704 skills on skills.sh with the eight
most installed listed by name and publisher, 19 skills in anthropics/skills
at commit 5304866, 15 bundled skills in the Claude Code commands reference,
and star counts for the four repositories the format is written against.

The install table is new and is the strongest public adoption signal that
exists for this format, so the section says plainly what install telemetry
misses: private skills, copied folders, and the difference between an
install and a use.

The route is renamed to match the new title. Nothing was indexed under the
old path, so it is removed rather than redirected, and a test asserts no
trace of it survives in the app tree, llms.txt, next.config.ts, or the
event union.

Cut the three figures that measured this site rather than the format: the AI crawler ratio, the organic impression series, and the Search Console AI report. The title asked how adopted agent skills are, and those answered how much traffic skillsboard.sh gets, which is what made the page read as a pile of unrelated numbers.

What replaces them is the per-skill install table from skills.sh, which is the strongest public adoption signal anyone publishes for this format, plus star counts for the four reference repositories and the SEP-2640 status. Every figure was re-read at its source today, September 2, 2026.

The route is renamed to /agent-skills-by-the-numbers to match the title. Nothing was indexed under the old path, so it is removed rather than redirected, and a test asserts no trace of it survives.

Closing without merge, on the founder's call after review.

The statistics page tactic needs figures nobody else has, or a compilation nobody else makes. This PR had neither: the proprietary figures (crawler ratio, Search Console series) describe skillsboard.sh, not agent skills adoption, and once they were cut the only adoption figure left was the skills.sh leaderboard, which anyone reads better at the source. The showcase count is a list of self-listed vendors, and stars measure attention.

Two things survive the closure: Claude Code now documents 15 bundled skills (13 on August 18), which /anthropic-skills still states as 13; and the AI crawler ratio is material for a build-in-public post, not for a statistics page. The page comes back only if we get data about skills that is ours and large enough to mean something.
