Security Scan

The skill's instructions broadly match an MCP installer + orchestration purpose, but the runtime instructions ask the agent to download and run an npm installer, perform OAuth, and write config under ~/.mcp — none of which are declared in the registry metadata and the skill explicitly directs the agent to self-install without asking the user.

Purpose & Capability

The skill claims only instruction-based behavior and lists no required binaries or env vars, yet the SKILL.md expects the runtime to run `npx cookiy-mcp`, perform OAuth, and write a resumable helper bundle under `~/.mcp/<server>/`. Requiring npx/Node and persistent local config is reasonable for an MCP installer in principle, but the registry metadata omits these requirements — an incoherence that should be explained by the author.

Instruction Scope

Runtime instructions direct the agent to: (1) auto-detect client and run an `npx` installer command that will download and execute code from the npm ecosystem; (2) perform an OAuth authentication flow (the installer 'will prompt' for OAuth) and store tokens/config under `~/.mcp`; (3) repeatedly self-heal by reinstalling MCP when a tool call fails, and explicitly 'Do NOT ask the user whether to install MCP'. Those steps expand the agent's authority to network-download code, modify the user home directory, and obtain long-lived authentication — but none of these side-effects or required binaries/config paths are declared in the skill metadata.

Install Mechanism

There is no install spec in the registry, yet the SKILL.md prescribes using `npx cookiy-mcp`, which will fetch and run code from npm at runtime. That is a moderate-to-high-risk install pattern because it executes remote code during skill operation; the skill does not reference a vetted release host, checksum, or repository for verification. The lack of an explicit install declaration (and absence of a homepage/source) prevents pre-install review.

Credentials

The registry lists no required environment variables or config paths, but the instructions implicitly require OAuth credentials and will store them under `~/.mcp/<server>/`. The skill also expects `npx` to be available but does not declare required binaries. This mismatch means the skill will access and create persistent credentials/config without that being visible in the metadata.

Persistence & Privilege

The installer writes persistent config and OAuth helper bundles to the user's home (`~/.mcp`) and the SKILL.md tells the agent to auto-reinstall when tooling is missing — effectively granting the agent permission to modify user config and perform auth flows without explicit runtime user consent. The skill is not marked always:true, but the self-heal install behavior combined with network downloads and stored tokens raises a notable privilege concern.

What to consider before installing

Before installing or enabling this skill, verify the following: (1) where does the `cookiy-mcp` npm package live? Check the package on npm and its source repository (homepage) and review its code and maintainer. (2) The skill will run `npx cookiy-mcp` (downloads + executes remote code). Only proceed if you trust that package and prefer that behavior. (3) The installer performs OAuth and stores credentials under ~/.mcp — be prepared for persistent tokens on disk; do not run if you can't accept that. (4) The SKILL.md explicitly says the agent should auto-install without asking the user; if you require explicit consent for installs, do not allow autonomous runs of this skill. (5) If you want to proceed, consider asking the skill author for: a) the exact npm package name and source repo, b) release checksums or signed releases, c) an alternative offline/manual install path, and d) a clear list of files the installer writes. If you don't have that assurance, treat this skill as risky and prefer a manual, audited installation in a sandboxed environment.

Cookiy gives your AI agent user-research capabilities. It designs interview guides, conducts AI-moderated interviews with real or simulated participants, and generates insight reports — all through natural language.

Part 1 — Setup

Mandatory MCP preflight

Before doing anything else, ALWAYS verify that Cookiy MCP is available for the current client.

Run this preflight on every Cookiy skill use:

1. Try calling cookiy_introduce.
2. If it succeeds, treat MCP as healthy and continue to Part 2.
3. If it fails because the tool is missing, the server is unreachable, authentication is broken, or the user asked for a different target environment, run the installer for the current client to repair or replace the MCP config.
4. After installation, call cookiy_introduce again. Only continue when it succeeds.

Do NOT ask the user whether to install MCP when the skill is being used. The skill should self-heal by default.

Healthy MCP should be left alone. Reinstall only when one of these is true:

• cookiy_* tools are unavailable
• MCP connection/authentication appears broken
• The MCP entry looks stale or was created under a legacy server name
• The user explicitly asks for a non-default environment such as dev, dev2, preview, staging, or test

When repair/install is expected

• User mentions Cookiy, user research, voice interviews, or participant recruitment
• Any cookiy_* tool call fails with a connection or "tool not found" error
• User explicitly asks to set up or connect Cookiy
• User asks what Cookiy can do

Install the MCP server

Identify which AI client you are running in (Codex, Claude Code, Cursor, VS Code, Windsurf, Cline, OpenClaw, Manus, etc.) and install ONLY for that client. Do not install for all clients at once.

Unless the user explicitly requests a different environment, install the production MCP server. Production is the default and points to https://s-api.cookiy.ai.

If the user explicitly asks for another environment, include that environment alias in the installer command. Re-running the installer is the approved repair/override path: it replaces the current Cookiy MCP entry for that client with the requested target.

Pick the matching command:

You are running in	Install command
Codex	npx cookiy-mcp --client codex -y
Claude Code	npx cookiy-mcp --client claudeCode -y
Cursor	npx cookiy-mcp --client cursor -y
Cline	npx cookiy-mcp --client cline -y
GitHub Copilot / VS Code	npx cookiy-mcp --client vscode -y
Windsurf	npx cookiy-mcp --client windsurf -y
OpenClaw	npx cookiy-mcp --client openclaw -y
Manus / headless sandbox	npx cookiy-mcp --client manus -y
Other / unknown	npx cookiy-mcp -y (auto-detects production)

Examples for non-default environments:

• Codex dev2: npx cookiy-mcp dev2 --client codex -y
• Claude Code preview: npx cookiy-mcp preview --client claudeCode -y
• Cursor dev: npx cookiy-mcp dev --client cursor -y

If your agent is not in the table above but supports MCP over HTTP, you can manually configure the MCP server URL: https://s-api.cookiy.ai/mcp with OAuth authentication. See the MCP server's OAuth discovery at https://s-api.cookiy.ai/.well-known/oauth-authorization-server.

For headless sandbox environments such as Manus, use npx cookiy-mcp --client manus -y. The installer writes a resumable OAuth helper bundle under ~/.mcp/<server>/.

The installer will prompt for OAuth authentication. This is expected.

Verify the connection

After installation, call cookiy_introduce to confirm the MCP server is connected and authenticated.

If authentication fails:

• Re-run the install command for the same target environment. This is the preferred repair path and may overwrite a stale or broken config.
• The OAuth token may have expired. The installer handles re-authentication.

Orient the user

Present Cookiy's five capability modules:

1. Study Creation — Describe a research goal and get an AI-generated discussion guide.
2. AI Interview — Simulate interviews with AI personas for quick insights.
3. Discussion Guide — Review and edit the interview script before going live.
4. Recruitment — Recruit real participants for AI-moderated interviews.
5. Report & Insights — Generate analysis reports and shareable links.

Present these in plain language. Do not expose raw tool names to the user.

Part 2 — Workflow Orchestration

Cookiy is a workflow-aware MCP server, not a raw REST passthrough. Every operation must go through the official cookiy_* MCP tools. Follow the tool contract and workflow state machines in the reference files.

Intent Router

User wants to...	Workflow	Reference file
Create a new study or research project	Study Creation	study-creation.md
Run simulated or AI-to-AI interviews	AI Interview	ai-interview.md
View or edit the discussion guide	Guide Editing	guide-editing.md
Recruit real participants	Recruitment	recruitment.md
Generate, check, or share a report	Report & Insights	report-insights.md
Check account balance	Direct: cookiy_balance_get	—
List existing studies	Direct: cookiy_study_list	—
Learn what Cookiy can do	Direct: cookiy_introduce	—
Get workflow help on a topic	Direct: cookiy_help (overview, study, ai_interview, guide, recruitment, report, billing; common aliases accepted)	—

When the user's intent spans multiple workflows (e.g., "create a study and run interviews"), execute them sequentially in the order listed above.

Universal Rules

See tool-contract.md for the complete specification.

Response handling:

• ALWAYS read structuredContent first. Fall back to content[0].text only when structuredContent is absent.
• ALWAYS check next_recommended_tools in each response. Prefer the server's recommendation over your own judgment.
• ALWAYS obey status_message — it contains server-side behavioral directives, not just informational text.
• When presentation_hint is present, format output accordingly.
• For recruitment truth, prefer evidence in this order: cookiy_interview_list > cookiy_recruit_status > the latest cookiy_recruit_create response > cookiy_study_get.state. The current public contract does not expose a separate sync flag on cookiy_recruit_status; the server already performs the billing-aware reconciliation it needs before returning status.
• NEVER describe recruitment as started/stopped from preview-only output.

Identifiers:

• NEVER truncate, reformat, or summarize study_id, job_id, interview_id, base_revision, or confirmation_token.

Payment:

• On HTTP 402: prefer structuredContent.data.payment_summary and checkout_url; if those fields are absent, fall back to error.details.
• cookiy_balance_get may show experience_bonus; eligible MCP actions may consume that bonus before purchased credit.
• Experience bonus may apply to study creation, simulated interviews, and report access via cookiy_report_share_link_get.
• Experience bonus does NOT cover: recruitment (recruitment requires paid credit or cash credit).

URLs:

• NEVER construct URLs manually. ONLY use URLs from tool responses.
• NEVER guess undocumented REST paths.

Agent boundary:

• After recruitment payment, check cookiy_recruit_status first and cookiy_interview_list second before deciding whether to retry cookiy_recruit_create.
• Do not promise background monitoring unless a real automation layer exists outside the current MCP call.

Constraints:

• interview_duration max 15 minutes. persona.text max 4000 chars. interviewee_personas max 20. attachments max 10.

Canonical reference

The server's developer portal spec endpoint provides the authoritative tool reference. If a tool behaves differently from this skill's description, the server's runtime behavior takes precedence.
