No CLI install needed; audited products may require their own credentials at runtime. license MIT metadata {\"author\":\"jay-sahnan\",\"version\":\"1.4.0\"} allowed-tools Read WebFetch Write Bash AskUserQuestion Agent Audit Agent Experience Evaluate how well a product/SDK/docs surface works when an AI agent actually tries to onboard and do a realistic task — starting from a short one-sentence prompt , with nothing pasted in. The agent must find the docs, install what it needs, and attempt real work. That's the only honest test of agent DX. The skill spawns multiple subagents in parallel, captures each one's tool-call trace, and scores the experience using the same dimensions as the Skill Test Arena dashboard: Setup Friction, Speed, Efficiency, Error Recovery, Doc Quality. Core principle Do not spoonfeed. The subagent gets a tiny prompt like \"Get started with {product} and {do its primary thing}\" . It must discover the docs, choose the path, and hit real failures. A good doc survives this; a bad doc does not. Workflow Execute these steps in order. Do not skip ahead. Step 1 — Identify the target and define the abstract goal Resolve what the user is asking to audit. The target may arrive in one of three forms: URL — a docs site or product page (e.g., https://docs.example.com ). This is the seed the subagents start from. Repo / file path — for SKILL.md audits or SDK repos. Product name — if the user is vague (\"test my product\"), ask via AskUserQuestion for the URL or repo. This skill is product-agnostic. Never assume what the user wants to audit. Do not infer a target from environment signals (operator's email domain, git remote, repo name, recent files, memory, CLAUDE.md). Even if context strongly suggests a particular company, the user-facing question must NOT pre-fill or default to any specific product, URL, or company name. Ask open-endedly with neutral options only: e.g., \"Paste a URL\", \"Paste a local path\", \"Type a product name\". If the user did not name a target in their invocation, ask them — start fresh, no priors. Research lightly after the user has named a target. 1 WebFetch max, enough to confirm: what is this product, and does it have a getting-started guide? You're identifying that there is a flow to follow , not extracting the steps. The whole point is to let the docs dictate the path. Define ONE abstract goal, not a step-by-step checklist. The goal should be at the level of \"complete the onboarding\" or \"make the product do its primary thing once\" — NOT a list of specific actions. Why: prescriptive checklists steer agents. If you tell them \"navigate to example.com\" but the docs' quickstart navigates to a different URL, the agent is torn between your instruction and the docs. That pollutes the test. Examples of good abstract goals (the target product is supplied by the user — the examples below are illustrative only, not defaults): A search API → \"Complete the getting-started guide. Success = your code successfully calls the API and prints whatever the docs treat as a meaningful result.\" A payments API → \"Complete the getting-started flow for making a test charge. Success = you have a charge ID or equivalent confirmation.\" A browser-automation SDK → \"Complete the getting-started guide end-to-end. Success = you have code that runs a cloud browser session using whatever approach the docs recommend.\" A SKILL.md → \"Follow the skill's instructions and produce a successful outcome for its advertised job.\" Examples of BAD goals (too prescriptive — don't do this): \"Navigate to https://example.com \" (steers — the docs may pick a different URL) \"Use Playwright\" (the docs may recommend Stagehand or Selenium) \"Print the page title\" (the docs may print session ID, response body, anything) The subagent will self-report against the abstract goal: did I complete the onboarding as the docs described? (yes / no / partial). The concrete sub-outcomes the agent actually achieved live in their trace under primary_outcome_achieved , not in a pre-defined checklist. If the target has no clear getting-started flow (rare — even a README is a flow), ask the user what \"done\" means before continuing. Step 2 — Gather audit config via AskUserQuestion Use AskUserQuestion in a single call with 4 questions . Options: max 4 per question. Test depth (single-select, header: \"Depth\" ): 5 agents (Recommended) — balanced coverage 3 agents — quick sanity check 10 agents — thorough, higher cost Programming languages (multiSelect, header: \"Languages\" ): pick up to 4 — Python , TypeScript , Go , Shell/Bash (let user deselect). Personas (multiSelect, header: \"Personas\" ): Standard (Recommended) — neutral baseline, no behavioral flavoring. Just \"do the task.\" Best for unbiased measurement. Pragmatic — just get it working, fastest path Thorough — read the docs end-to-end before coding Skeptical — verify claims the docs make Execution mode (single-select, header: \"Exec mode\" ): Allow Bash (Recommended) — subagents can run npm install , curl , etc. on your machine. Most realistic. Draft-only — subagents may fetch docs and write code but won't execute anything. Safer. After the user answers, gather one more question about model choice: Model (single-select, header: \"Model\" ): Sonnet (Recommended) — balanced cost/quality, default for most audits Opus — strongest reasoning, highest cost; good for dense/ambiguous docs Haiku — cheapest, fastest; good for checking if docs are agent-friendly to smaller models Mixed comparison — split agents across Opus + Sonnet + Haiku so you can see how doc quality varies by model size. Useful for \"are my docs robust even to weaker models?\" Pass the chosen model to each Agent invocation via the model parameter. If Mixed , distribute N agents roughly equally across the 3 models (round-robin by slot index) and record which model each agent used in the trace + report. After the user answers, you have: depth (N), languages[] , personas[] , exec_mode , model . If exec_mode = \"Allow Bash\" , follow up with a second AskUserQuestion asking about credentials: Credentials (single-select, header: \"Credentials\" ): Auto-discover (Recommended) — skill checks the user's env vars, common dotfiles, and credential managers; only prompts for paste if nothing found. Best for repeat use and for cases where another operator is running the audit. None — let agents block (friction test) — agents hit the credential wall, counts as Setup Friction. Best for pure docs audits. Paste manually — you paste keys directly; skill injects them. Use when you don't have keys stored locally yet. If user picks Auto-discover , run Step 2.5 below before continuing. If Paste manually (or auto-discover falls back), AskUserQuestion asks for the credential values — not the names. The skill then writes them to each workspace .env using generic, product-agnostic names : Primary credential → API_KEY Secondary (e.g. project/org ID) → PROJECT_ID Third (e.g. webhook secret) → SECRET Do NOT use product-specific names like BROWSERBASE_API_KEY , EXA_API_KEY , STRIPE_SECRET_KEY . Those names steer the agent — they see BROWSERBASE_API_KEY in env and skip ever reading the docs to find out what env var the SDK actually expects. The generic name forces them to: Read the docs to discover the product's actual env var name (e.g. BROWSERBASE_API_KEY ). Map the generic API_KEY value into whatever form the SDK requires — either re-export ( export BROWSERBASE_API_KEY=$API_KEY ) or pass inline in code ( new Browserbase({ apiKey: process.env.API_KEY }) ). If an agent fails to figure out the mapping, that's a doc quality signal — the docs weren't clear about credential naming. Step 2.5 — Credential auto-discovery (only if user picked Auto-discover ) Run a tiered lookup. Stop at the first tier that produces a usable candidate. Never print credential values to chat — only names and source paths. The user picks by name; the skill internally maps name → value → workspace .env . Derive the product slug from the target URL/repo to bias toward relevant matches. e.g. https://docs.browserbase.com → slug browserbase . Use lowercase substring match (case-insensitive) when ranking candidates. Tier 1 — Already-exported env vars (free, zero side effects): printenv | grep -iE '^[A-Z][A-Z0-9_]*_(API_KEY|TOKEN|SECRET|KEY)=' | cut -d= -f1 This returns names only. If any names contain the product slug, those are top candidates. Tier 2 — Narrow dotfile scan (a hardcoded short list, NOT a recursive grep): grep -hE '^[[:space:]]*export[[:space:]]+[A-Z][A-Z0-9_]*_(API_KEY|TOKEN|SECRET|KEY)=' \\ ~/.zshrc ~/.bashrc ~/.bash_profile ~/.zprofile ~/.env ./.env ./.envrc 2>/dev/null \\ | sed -E 's/^[[:space:]]*export[[:space:]]+([A-Z0-9_]+)=.*/\\1/' \\ | sort -u Files allowed: ~/.zshrc , ~/.bashrc , ~/.bash_profile , ~/.zprofile , ~/.env , ./.env , ./.envrc . Do NOT expand this list. Do NOT recurse. Do NOT scan ~/Library , ~/.config/ , ~/Documents , etc. This is the entire allowlist; anything else is out of scope and risks leaking unrelated secrets. For each match, record (NAME, source_path) . Read the value lazily — only when the user has confirmed the choice — by re-grepping the specific source file for that exact name. Tier 3 — Credential manager (only if op or security is on PATH AND tiers 1–2 had no good match): 1Password CLI: skip unless op account list exits 0 (i.e. user is signed in). Don't trigger an interactive auth flow inside the skill. macOS Keychain: security find-generic-password -l \"<expected-name>\" -w — try once with the most likely name (e.g. BROWSERBASE_API_KEY ); silent failure means not stored. If a credential manager produces hits, list them as candidates the same way as tiers 1–2. Tier 4 — Fallback to paste: If all tiers above produced zero candidates, fall through to the manual paste flow described in Step 2. Presenting candidates to the user. After tiers 1–3: If exactly 1 candidate and its name contains the product slug → use it silently. Log a one-line confirmation in chat: Using BROWSERBASE_API_KEY from ~/.zshrc. (Name + source only — never the value.) If multiple candidates , AskUserQuestion (single-select, header: \"Use which credential?\" ) with up to 4 options: One option per top candidate, formatted <NAME> (from <source>) Plus a Paste manually instead escape hatch If >3 candidates, show the top 3 by slug-relevance and add a Show all option that re-asks with the rest. If no candidates → fall through to Tier 4 (paste). Reading the value. Once the user has confirmed a choice (or it was auto-selected), read the value: Tier 1: printenv <NAME> (capture stdout, do not echo). Tier 2: re-grep the specific source file for the exact export <NAME>= line and parse the RHS, stripping surrounding quotes. Tier 3: op read \"op://<vault>/<item>/<field>\" or security find-generic-password -l <NAME> -w . Write the value into per-agent workspace .env files using the same generic names ( API_KEY , PROJECT_ID , SECRET ) as the paste flow — see Step 2. The discovery layer is upstream of injection; downstream behavior (generic names, agent must read docs to map them) is unchanged. Orchestrator-retained credentials. After writing per-agent .env files, the orchestrator keeps the original product-specific names → values (e.g. BROWSERBASE_API_KEY ) available to itself for downstream verification work in Steps 6 / 6.5 / 8 — for example, calling the product's API with curl to confirm that a session ID an agent reported actually resolves, or fetching session metadata to enrich the report. The orchestrator can read them with printenv (no need to store anywhere — the parent shell already has them since auto-discover sourced them from there). This is asymmetric on purpose: the subagents see only generic API_KEY / PROJECT_ID / SECRET so the doc-quality test stays honest (they must read the docs to discover the real var name). The orchestrator is not being audited, so it can use the real names freely for verification. Privacy guarantees the skill must uphold: Never write a credential value to chat output, the trace, the report, or any file outside the per-agent workspace .env . Never re-export the value into a subagent's workspace under a product-specific name. Subagents only see the generic names. Treat values as opaque strings — do not log length, prefix, or fingerprint. The HTML report records that auto-discovery happened (and which name was used) but never the value. Step 3 — Safety check If exec_mode = \"Allow Bash\" , print a brief warning to chat before spawning: \"Agents may run real shell commands (npm install, curl, pip install, git clone) on this machine. Make sure you're in a directory you're okay with agents modifying. Continue in 5 seconds or Ctrl-C to abort.\" — then continue. Do not run sleep — just proceed after printing. The user reads the warning before the agents start working. Step 4 — Generate tiny prompts (no checklist) For each of N variants, produce a (persona, language, prompt) tuple. The prompt is one or two sentences , stating the abstract goal + language. No sub-checklist, no prescriptive steps. Template: {persona_prefix} {product}'s getting-started guide using {language}.{persona_tail} You've completed it when you've done whatever the guide treats as the primary successful outcome. {persona_tail} is empty for most personas. The Skeptical persona uses it to inject its \"note anything wrong\" guidance as a separate sentence (with a leading space) so the prefix sentence stays grammatical. See references/prompt-variants.md for the full prefix/tail per persona. Examples (using Acme as a placeholder — substitute the user-supplied product name): Pragmatic × TypeScript → \"Skim and then follow Acme's getting-started guide using TypeScript (Node.js). You've completed it when you've done whatever the guide treats as its primary successful outcome.\" Thorough × Python → \"Read and then follow Acme's getting-started guide using Python. You've completed it when you've done whatever the guide treats as its primary successful outcome.\" Skeptical × Shell → \"Follow Acme's getting-started guide using bash/curl only. Note anything in the docs that seems wrong or unclear as you go. You've completed it when you've done whatever the guide treats as its primary successful outcome.\" The subagent is NOT told what the success outcome is — they have to read the docs to figure that out. That's the point: if the docs are good, they'll convey it clearly. If the docs are bad, the agent won't know when they're done, which IS a finding. Read references/prompt-variants.md for the persona prefix library. Cross-product personas × languages, truncate to N. If cells < N, repeat with slight wording variation on the prefix. Never paste doc content into the prompt. Step 5 — Spawn N subagents in parallel Read references/subagent-brief.md — the full brief each subagent receives. It tells them: You are a real developer doing a real task Use your real tools ( WebFetch , Bash if allowed, Write ) If you need credentials, ask the user via a clear stop-and-ask message (the skill captures this as friction) Return a structured trace at the end with tool calls, errors, timing estimates, completion status For each variant, invoke the Agent tool (subagent_type: general-purpose ). Pass model: \"opus\" | \"sonnet\" | \"haiku\" per the user's choice. For Mixed , rotate models across the N slots deterministically (agent 1 → opus, agent 2 → sonnet, agent 3 → haiku, agent 4 → opus, …) and record the assigned model in the per-agent report row. All N calls in one message so they run in parallel. The subagent's prompt = the brief + their tiny task. The brief passes through exec_mode so the subagent knows whether Bash is available. Wait for all N agents to return before continuing to Step 6. When agents are run in the background, completion notifications arrive one at a time and it is easy to lose count. Maintain a simple in-memory tally of returned-vs-spawned and, when the last agent reports back, print one explicit milestone line to chat: \"All N agents returned — moving to trace parsing.\" Do not start Step 6 until that line has been printed. If the user asks \"are the agents still running?\" mid-flight, answer with the current <returned>/<spawned> count from your tally, not from re-counting prior chat output. Verification of agent claims using orchestrator credentials. Before scoring, if Step 2.5 retained product-specific credentials, the orchestrator may use them to spot-check claims that subagents made (e.g. confirming a session ID with curl -H \"X-BB-API-Key: $BROWSERBASE_API_KEY\" https://api.browserbase.com/v1/sessions/<id> ). Treat any unresolved IDs as evidence the agent may have hallucinated. Never include the credential header in the report — only the verification result (resolved / not resolved). Step 6 — Parse structured traces AND keep the full prose Each subagent returns two things in one response: A fenced JSON trace at the end (structured self-report). All the prose before it — reasoning, tool output, and what the agent actually did. Retain both. Do not throw the prose away after extracting JSON. The prose is where you catch things the JSON self-report misses. Extract JSON using: /```json\\s*(\\{[\\s\\S]*?\\})\\s*```\\s*$/ . Mark malformed/missing as errored with a raw_tail . If >50% errored, warn and offer retry. Compute the top-line numbers from the JSON: Onboarding success rate = fraction of agents with onboarding_status = \"completed\" . Docs-promise-match rate = fraction of agents with docs_promise_met = true . Step 6.25 — Annotate URL provenance per-WebFetch (inline in trace) Subagents don't have search — they guess URLs from training-data priors. Reports must show per WebFetch call where the URL came from, rendered as a small muted line directly under the tool input block in the trace. Do NOT put this at the top of the report as a general callout — it's only useful inline where the reader can correlate it to the specific call. Classify each WebFetch URL into one of four provenance categories and render with the matching label + color: TRAINING PRIOR (violet) — URL is a guess from training data (product name + common doc-site conventions like /introduction , /quickstart , /sdk/{lang} ). Typical for the first 1–2 WebFetch calls. FROM LLMS.TXT (blue) — URL appears in the output of a prior llms.txt fetch in the same trace. FROM PREV PAGE (green) — URL was listed in the output of a previous WebFetch or Bash tool call in the same trace. GUESS · 404 (amber) — URL was guessed but 404'd — this is the most interesting category for doc-quality scoring (the URL should exist by convention but doesn't). Classification heuristic:",
