Rudder Docs is an agent skill from Undertone0809/rudder. Use when the user asks how Rudder works; needs current Rudder docs, exact behavior, commands, contracts, APIs, or source evidence; asks to create, hire, or configure Rudder agents; or asks to scaffold, develop, or verify Rudder plugins. For explicit creation requests, verify the current interface before acting within existing authorization. Do not use for greetings, ordinary work merely running inside Rudder, routine actions already clear from the active context and typed tools, non-Rudder plugin work, or general…
Its SKILL.md is about 2.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 11 other files, including reference files (for example `evals/retrieval-authority-evals.json`, `evals/trigger-evals.json` and `references/agent-creation.md`).
The repository describes itself as: Open-source local Agent harness for self-improving agent teams: run agents, review work, and turn feedback into reusable skills. The licence is Apache-2.0.
7 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit b82f1b4. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Hosts in commands or code, which the agent is likely to contact:
docs.rudderhq.devFrom URLs in SKILL.md, links to its own repository left out.
Names these keys or tokens, usually read from environment variables:
RUDDER_API_KEYFrom names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Rudder Docs loads about 2.3k tokens when it runs, and up to ~22k if it reads all its reference files. Until then it costs about 147 tokens; SKILL.md has 1,132 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/rudder-docs/SKILL.md (or your agent's skills folder). This skill also uses 9 other files; get the full folder from GitHub.Provide authoritative, current guidance about Rudder. This is Rudder's documentation and self-knowledge entry point, not a workflow that must run merely because the agent is hosted by Rudder.
If this body is already present in the prompt but the current request does not need Rudder guidance, do not perform a docs lookup. Continue the user's actual task using the current tools and context.
Classify the Rudder question, consult the smallest authoritative source set, and answer with clear provenance. Use current evidence instead of memory for commands, interfaces, versioned behavior, and design proposals.
This router does not make an ordinary hosted task into a Rudder workflow. It does not provide a command catalog, replace runtime-owned execution rails, or authorize an operation merely because it documents that operation.
Choose one primary class before retrieving evidence:
For a mixed question, resolve each material claim through its owning source instead of applying one global priority.
Inspect exposed typed Rudder tools first. If capability discovery is needed,
use rudder agent capabilities --json; then use rudder --version and the
exact installed command's --help. Consult the relevant part of the CLI
reference only after those live checks. Use the API reference only for an
explicit internal, debugging, or compatibility question.
For Agent creation or configuration, read Agent creation. For Plugin scaffolding or authoring, read Plugin authoring. Verify the current typed capability, installed command, engineering contract, or source before acting. Only an explicit user request to perform the creation or change authorizes entering a mutation workflow; a question about how it works remains read-only.
For public user guidance, start with
https://docs.rudderhq.dev/llms.txt. Open only one or two official pages
relevant to the request, prefer the user's language when an equivalent page exists, and link the
exact page. Do not crawl or load the whole site for a narrow question.
Follow the checkout's AGENTS.md, then use doc/README.md to choose the
documentation layer: docs/ for public user guidance, doc/plans/ for design
proposals, doc/engineering/ for contributor detail, and
source and tests for exact implementation. Search the owning area narrowly and
cite local paths and line numbers when supported.
When local source is unavailable and source evidence is necessary, use only
the official https://github.com/Undertone0809/rudder repository and its
release or tag pages by default. Match the release tag to the installed version
when explaining installed behavior. Use the default branch only for explicit latest development questions, and label it as latest development, not installed behavior.
Offline, use live capabilities and the relevant bundled references, and disclose which preferred source was unavailable, the fallback used, and the resulting limits. Missing evidence narrows the answer; it does not justify invention.
Current callable or installed behavior wins for this environment. Proposals record intended changes and rationale. Source and tests own exact implementation evidence. Public docs own published user guidance. An official release or tag owns version-specific history.
Do not flatten disagreement:
State conflicts and bounded uncertainty explicitly. Do not average sources together or imply certainty that the evidence does not support.
Read only the reference needed for the request:
RUDDER_API_KEY for documentation lookup.docs.rudderhq.dev and
github.com/Undertone0809/rudder, including that repository's official
releases and tags. Follow stricter host policy when it applies.doc/product/ registry is historical reference, not an approval gate.Before answering:

Run `npx skills add Undertone0809/rudder --skill rudder-docs -a claude-code`. Or copy the skill folder (server/resources/bundled-skills/rudder-docs in Undertone0809/rudder) into .claude/skills/rudder-docs in your project. Claude Code loads it when a task matches its description.
Run `npx skills add Undertone0809/rudder --skill rudder-docs -a codex`. Or copy the skill folder (server/resources/bundled-skills/rudder-docs in Undertone0809/rudder) into .agents/skills/rudder-docs in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Undertone0809/rudder --skill rudder-docs -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/rudder-docs, .gemini/skills/rudder-docs, .github/skills/rudder-docs and .opencode/skills/rudder-docs in your project.
Going by SKILL.md and its folder, Rudder Docs needs credentials named RUDDER_API_KEY. Our summary lists: A credential in RUDDER_API_KEY.
SKILL.md names 1 domain. In commands or code: docs.rudderhq.dev; the agent is likely to contact it when it follows the instructions. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Rudder Docs is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.3k tokens (SKILL.md is roughly 9.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 20k tokens, read only when the agent opens those files.
