Camunda Docs Lookup

UTILITY SKILL: retrieve source-backed Camunda documentation, then route implementation work to the focused skill.

DO NOT USE FOR:

Do not use this skill to author BPMN, DMN, forms, or connectors, or to deploy and operate process instances. Route those tasks to the corresponding Camunda skill after verifying any version-sensitive fact here.

Two retrieval paths into docs.camunda.io, each with a different strength. Pick by question shape; fall back to llms.txt only if both are unavailable.

Use both primary paths in parallel when in doubt — they're cheap and frequently surface different relevant pages.

camunda-docs MCP server

If the camunda-docs MCP server (https://camunda-docs.mcp.kapa.ai, HTTP transport) is connected, call its knowledge search tool with a single, well-formed natural-language sentence (the tool requires a complete sentence, not keywords).

If it isn't connected, suggest configuring the server once so the user has it set up for future questions. Skip the suggestion if you've already made it earlier in this conversation. Add the HTTP server at https://camunda-docs.mcp.kapa.ai using the harness's documented MCP configuration flow. For VS Code Copilot, Cursor, or other generic MCP clients, see the reference. Google sign-in on first use; 40 requests/hour and 200/day per user; not for CI.

Algolia DocSearch

A bash wrapper around the public Algolia DocSearch endpoint lives at $CAMUNDA_DOCS_SKILL_DIR/scripts/docs-search.sh. Set CAMUNDA_DOCS_SKILL_DIR to the installed camunda-docs directory before running it:

"$CAMUNDA_DOCS_SKILL_DIR/scripts/docs-search.sh" "<query>" [--version stable|next|<major>.<minor>|all]

Default --version stable resolves to the highest numeric version in the index (so it keeps working when 9.0 ships). Default --limit 10. Returns JSON:

• total — hits in this response.
• total_matching — raw count of pages matching the query in the index, before pagination/dedupe. Useful for "how broadly does my term appear?"
• algolia_version — the version facet value sent to the index (e.g. "8.9", "current"). null in --version all mode (no facet filter applied).

Search flow

1. Pick a version (see table below). Default stable.
2. Run the script with --limit 5 first, on a single line (no \ continuations — interactive shells can stall on them). Every hit stays in context for the rest of the task, so widen the limit only if the first page misses.
3. Inspect the hits — each has url, hierarchy, title, snippet.
4. Fetch the most relevant page(s) directly by URL to read full context. Snippets are short; don't answer from them alone if the question needs detail.
5. Refine if insufficient — see refinement strategy below.

Version handling

The Camunda docs are versioned in the URL path. The Algolia version facet exposes those versions — without filtering, the same page returns 3-4 times across versions, which is noisy.

Pick explicitly when:

• Question is about a specific customer/cluster on a known generation → use that version.
• Question is about an upcoming feature, an alpha, or "will this change in 8.10?" → run stable and next in parallel and compare.
• Question is version-neutral (concepts, BPMN semantics, generic API shape) → stable is fine.

In --version all mode the script over-fetches (4× --limit, capped at 100) so that after dedupe by URL stem the response contains close to --limit unique pages. Dedupe preserves Algolia's relevance order — first hit per unique URL stem wins, then trimmed to --limit.

Examples

The shell starts in the user's project directory, not the installed skill directory. Set CAMUNDA_DOCS_SKILL_DIR to the installed camunda-docs directory (the directory containing this SKILL.md) before running the wrapper, or have the host adapter provide it.

Refinement strategy

If the first query is unhelpful:

• Too broad → too many off-topic hits: add specifics (component, error code, config key).
• Too narrow → no hits: drop adjectives, try the canonical product term (e.g. "Tasklist" not "task UI", "Zeebe" not "workflow engine").
• Wrong version: try --version all to see if the term exists elsewhere, then narrow to the right release.
• Synonyms: try alternative names — e.g. "Operate" ↔ "process monitoring", "Optimize" ↔ "analytics".

Don't loop more than 2-3 refinements. If still nothing, switch to the MCP path (or note the gap to the user).

No credentials needed

The Algolia search-only API key is public — Algolia ships it in the browser JS bundle of docs.camunda.io, so every visitor already has it. It's hardcoded at the top of "$CAMUNDA_DOCS_SKILL_DIR/scripts/docs-search.sh" with a comment explaining why it's safe to commit. No credentials or API environment variables are required, and the wrapper is safe in CI.

Without the wrapper script

If you can't or don't want to run "$CAMUNDA_DOCS_SKILL_DIR/scripts/docs-search.sh" (e.g. jq missing, restricted sandbox, or you just need the raw API), call the Algolia endpoint directly:

Substitute the version: facet for the version you want (current for next, omit facetFilters entirely for all). The response shape is Algolia's raw hits — useful fields per hit are url, hierarchy.lvl0..lvl5, and content. If curl itself isn't available either, use any HTTP client that can POST JSON (Python urllib, Node fetch, PowerShell Invoke-RestMethod); the endpoint, headers, and body are the same. The credentials in the snippet are public by design (see "No credentials needed" above).

Fallback: llms.txt (docs index)

If neither MCP nor Algolia is usable, fetch https://docs.camunda.io/llms.txt (~540 KB) — an index of - [Title](url): description. lines for every Camunda 8 docs page. Do not read the whole file into context. Cache it locally, search for the term to find the matching URL, then fetch that page directly.

Last resort: llms-full.txt (full docs corpus)

Only if llms.txt doesn't surface what you need, fall back to https://docs.camunda.io/llms-full.txt (~11 MB) — every docs page concatenated. Even larger; never read whole into context. Cache locally, search with surrounding context for the term. Use when the right page name isn't obvious from the index.

Troubleshooting

• If MCP is unavailable, use "$CAMUNDA_DOCS_SKILL_DIR/scripts/docs-search.sh" when curl and jq are installed.
• If Algolia search fails, use the llms.txt index to locate a page, then fetch that page directly.
• If no source is reachable, state that the lookup is unverified instead of presenting remembered behavior as current.`
