description

Analyze every Claude Code skill (`.claude/skills/*/SKILL.md`) and agent (custom definitions under `.claude/agents/*.md`, plus built-in agent types referenced from skills via the `Agent` tool) defined in this repository, and generate/update the Antora documentation describing them — a reference table and dependency graph in `index.adoc`, purpose-grouped sections for the catalog's recurring end-to-end workflows, and one detail page per skill/agent under `docs/modules/ROOT/pages/skills/` and `.../agents/` covering its purpose, inputs, outputs, execution flow, and dependencies. Invoke as `/analyze-claude-skills-and-agents`. Idempotent — safe to re-run whenever skills/agents are added, removed, or changed; it regenerates content from the current `SKILL.md`/agent definitions rather than hand-maintaining pages that drift from them. Use whenever this catalog's own documentation needs to reflect its actual current set of skills and agents, instead of manually writing or updating each page by hand.

Analyze Claude Skills and Agents

Turn the actual, current set of Claude Code skills and agents defined in this repository into an Antora documentation site: a reference table, a dependency graph, purpose-grouped workflow walkthroughs, and one detail page per skill/agent. This skill only writes documentation — it never edits a SKILL.md, an agent definition, or any other source file. It makes no assumption about which skills or agents exist; discover the real, current set fresh each run so the generated docs never drift from what's actually on disk.

Step 1 — Locate the Antora documentation module

Find antora.yml (find . -name antora.yml -not -path '*/node_modules/*').

• Not found: there is no documentation module to write into yet. Ask the user whether to bootstrap one now via the antora-setup skill (run as a sub-agent via the Agent tool, briefed that it's about to be followed by this skill so its starter pages don't need to anticipate skill/agent documentation). If they decline, stop here — there's nothing for this skill to write into.
• Found: read it for the component name and the nav: file(s) it declares, then read that nav.adoc to get the current page list. Note the antora playbook (commonly antora-playbook.yml) and confirm it wires up a Mermaid extension — every diagram this skill produces is a [mermaid] block, and it's silently useless if the extension isn't configured. If it isn't, tell the user and either stop or fall back to plain bulleted/tabular descriptions instead of diagrams, per their choice.

Step 2 — Discover every skill and agent actually defined

• Skills: find .claude/skills -maxdepth 2 -name SKILL.md. Each is one skill; its directory name is its canonical name (should match the name: frontmatter field — flag any mismatch).
• Custom agents: find .claude/agents -maxdepth 1 -name '*.md' (the directory may not exist yet — that's not an error, just means there are none). Each is one custom agent definition.
• Built-in agent types actually used: grep every SKILL.md found above for Agent( / Agent tool / subagent_type usage. For each call site, note whether it names a specific agent type (e.g. "Explore") or omits subagent_type entirely (which resolves to Claude Code's default, general-purpose, at invocation time). Only document a built-in type here if some skill in this repository actually spawns it — don't produce a page for every agent type Claude Code ships, only the ones this catalog uses.
• Build a plain list of every skill name and every agent (custom or built-in-but-used) found. This is the complete inventory the rest of this skill documents — if it's empty of skills, tell the user there's nothing to document and stop.

Step 3 — Read and classify each skill/agent

For each skill, read its full SKILL.md and extract:

• Purpose: the one-line description frontmatter field, expanded into a short paragraph grounded in the skill's own opening paragraph and step list — don't just repeat the description verbatim on the detail page, explain it.
• Invocation and inputs: the Invoke as part of the description, plus whatever the skill's own early steps (usually "Step 1" or "Step 0") say about arguments — positional args, an args block of key: value lines accepted from an orchestrating skill, or no arguments at all. Note defaults and what happens when an expected argument is missing.
• Outputs: concrete artifacts and side effects — files created/modified, PRs/branches opened, or "a report only, no changes" for read-only skills. Ground this in the skill's own "Report" step and whatever Step explicitly writes/edits something.
• Execution flow: the numbered ## Step N headings, in order, including the real branches described in each step (a skill stopping early, an AskUserQuestion choice, a loop back to an earlier step).

For each custom agent (.claude/agents/*.md), extract the same shape from its frontmatter/body: what it's for, what tools it has, and what triggers its use.

For each built-in agent type found in Step 2, its "definition" is just how it's described in the session's own agent-type list (or, absent that, general Claude Code documentation) — summarize that briefly; the detail worth capturing is where and why this repository's skills use it, gathered in Step 4.

Step 4 — Build the dependency graph

For every skill, find every other skill/agent it depends on, in both directions:

• Skill invokes skill: search for Skill({skill: "<name>", ...}) calls, and prose like "invoke the <name> skill" or "run /<name>". Record the calling skill's step number and why (e.g. "to ground the plan in a prior exploration").
• Skill spawns agent: search for Agent({...}) calls. Record which built-in/custom agent type each one uses (or "default, i.e. general-purpose" if none is named) and why a sub-agent is used here specifically (context isolation from a verbose report, running a delegated skill with a clean context, parallelizing independent work) — this "why" belongs on both the skill's page and the agent's page.
• External dependencies: a skill may reference another skill by name that does not exist under .claude/skills/ in this repository (e.g. one assumed to be available globally/session-wide rather than checked into this catalog). Record these separately — they get named in prose on the relevant detail page(s) and in the dependency graph, but never get their own detail page or a broken xref: link.
• Invert the "invokes"/"spawns" edges to get "invoked by"/"used by" for each target.
• A skill or agent with no inbound edges from this repository's own skills is a top-level entry point (typically invoked directly by a person) — note that explicitly rather than leaving its "invoked by" section looking like an oversight.

Step 5 — Group by purpose

Cluster the skills into a small number of purpose groups based on the role each plays, using the dependency graph from Step 4 and each skill's own description as evidence — orchestrators and the skills they invoke usually belong together. Don't assume a fixed taxonomy or a fixed number of groups: infer groups that fit the actual current skill set, and expect this to change as skills are added or removed. Give each group a short, descriptive name and a one-paragraph summary of what it covers. Assign every skill to exactly one primary group, even if it's also reused from a workflow that spans groups (note that reuse in prose rather than double-counting it).

Step 6 — Identify the catalog's recurring end-to-end workflows

Separately from the purpose groups (which categorize skills), identify the handful of real, multi-skill sequences a user actually runs end to end — evidenced by an orchestrator skill's own step list, or by two standalone skills that are commonly run back-to-back per their own descriptions (e.g. "run after code has already changed"). Typical examples in a repository like this one: bootstrapping a brand-new repository, going from a tracked issue to an open/reviewed pull request, cutting a release, and refreshing docs/README/ changelog after unrelated code changes — but derive the actual list from what this repository's skills really support rather than assuming these four apply verbatim. For each workflow, note the ordered sequence of skills involved and any decision points (e.g. "hand off to /code automatically, or stop for manual review?").

Step 7 — Write index.adoc

Update (don't blindly overwrite unrelated hand-written content) the top-level page to contain, in this order:

1. Whatever introductory/conceptual material already exists (what this repository is, why it exists) — preserve it; only add a short "core concepts" note about agents if Step 2 found any custom or built-in agent usage and the page doesn't already explain the skill/agent distinction.
2. A reference table: one row per skill and per documented agent, with columns for name, purpose group (linking to that group's section via an anchor, e.g. xref:index.adoc#group-<slug>[]), a one-line purpose, and a link to its detail page (xref:skills/<name>.adoc[] or xref:agents/<name>.adoc[]). Every name in this table must resolve to a real page created in Step 8 — no dangling links, and no row for an external dependency that isn't actually part of this catalog.
3. Purpose groups: one subsection per group from Step 5, each with its own anchor ([[group-<slug>]] immediately above the === heading) matching what the table links to, a short description, and the skills it contains.
4. A dependency graph: a single [mermaid] flowchart (subgraphs per purpose group keep a catalog of more than a handful of skills readable) showing every "invokes" edge as a solid arrow and every "spawns an agent" edge as a dotted arrow, per Step 4. Name any external dependency in the diagram (e.g. as a dashed/external-looking node) without linking it anywhere.
5. Common workflows: one subsection per workflow from Step 6, each with a short [mermaid] flowchart of its skill sequence and prose noting any decision points and which skills also work standalone.

Match the AsciiDoc conventions already used on this page (table [cols=...] syntax, xref: link style, any existing AI-generated-content disclaimer note — keep it on every page you touch or create).

Step 8 — Write one detail page per skill and per documented agent

Create (or update, if re-running after a skill/agent changed) docs/modules/ROOT/pages/skills/<name>.adoc for every skill, and docs/modules/ROOT/pages/agents/<name>.adoc for every custom agent — or a single docs/modules/ROOT/pages/agents/overview.adoc covering all built-in agent types together, if there is no .claude/agents/ directory to give each one its own natural page. Give every page this shape:

1. = <Title> heading, then the repository's existing AI-generated-content disclaimer note if one is used elsewhere in this docs module.
2. A short intro paragraph (the expanded purpose from Step 3).
3. == Purpose — the fuller explanation of what problem this skill/agent solves and how it fits the catalog.
4. == Purpose group — an xref:index.adoc#group-<slug>[] link to its Step 5 group (skills only).
5. == Invocation and == Inputs — the slash command and a table of arguments (name, required, description, default), grounded in Step 3.
6. == Outputs — grounded in Step 3.
7. == Execution flow — a [mermaid] flowchart derived from the skill's real ## Step N headings (or the agent's real behavior) — collapse a long, repetitive sub-loop (e.g. "for each task: implement, test, document, quality-check") into one labeled node rather than drawing every sub-step literally, but don't omit a real branch or stopping condition.
8. == Dependencies with === Invokes / === Invoked by / === Related agents subsections (skills), or === Used by (agents) — every real edge from Step 4, each catalog skill linked via xref:skills/<name>.adoc[] and each documented agent via xref:agents/<name-or-overview>.adoc[]; external dependencies named in prose with no link; "None" stated explicitly rather than the section being silently empty when there really are no edges.
9. == Source — a link to the actual file this page documents, so a reader can jump straight from the generated docs to the definition it was generated from. Derive the repository's web URL and current branch (git remote get-url origin, git branch --show-current or equivalent default-branch lookup) once and reuse it for every page rather than hand-guessing or hardcoding a stale one. Skip this section entirely for a built-in agent type (there is no repository file to link to) or note "not tracked in this repository" instead of a broken link if the remote can't be resolved (e.g. no origin, or it isn't a web-viewable host).
   • Skill page link text: "SKILL.md on GitHub", target <repo-url>/blob/<branch>/.claude/skills/<name>/SKILL.md
   • Custom agent page link text: ".md on GitHub", target <repo-url>/blob/<branch>/.claude/agents/<name>.md

When re-running this skill after a skill/agent was added, removed, or materially changed: update only the pages whose source actually changed, add pages for new skills/agents, and remove pages (and their nav.adoc entries and any table rows/edges referencing them) for ones that no longer exist — don't regenerate every page from scratch on every run if most of the catalog is unchanged.

Step 9 — Update nav.adoc

Add an xref: entry for every new page from Step 8 that isn't already listed, nested under a "Skills" and, if any agent pages exist, an "Agents" heading (matching whatever nesting style nav.adoc already uses elsewhere in this module). Preserve the order and content of existing entries; remove entries only for pages Step 8 determined no longer exist.

Step 10 — Verify the site builds

From the docs module directory:

npx antora <playbook-file>

Fix any broken xref: (a typo'd skill/agent name, a page created under the wrong path), malformed table, or invalid Mermaid syntax before finishing — don't report success against a build that actually failed or warned about content this skill just wrote.

Step 11 — Report

Summarize: how many skills and agents were found and documented, the purpose groups and workflows identified (name them), any external dependency named but not linked, any page added/updated/removed versus the previous run (if this is a re-run), and the build result from Step 10. Remind the user to review the generated pages themselves, particularly the dependency graph and any workflow this skill inferred rather than found spelled out explicitly in an orchestrator skill's own steps.
