Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 5 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Agent Snooping · line 3 Skill accesses MCP server configuration files (mcp.json). MCP configs contain server URLs, authentication tokens, and tool definitions — reading them allows the skill to discover and potentially abuse other tool integrations.Fix: Remove all code or instructions that read MCP configuration files (mcp.json). MCP server details should be managed by the agent runtime, not read by individual skills.
- medium Data Exfiltration · line 7 Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.

- medium Excessive Agency · line 22 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00025 | $0.01170 |
| Opus 5 | $0.00013 | $0.00585 |
| Sonnet 5 | $0.00005 | $0.00234 |
| Haiku 4.5 | $0.00003 | $0.00117 |
Grade A, and why
you-discover scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You.com Discovery
Use this skill while planning how to integrate You.com with an agent SDK, IDE, automation platform, MCP client, API script, or other developer tool.
Required resources
- Check whether the standard You.com MCP server exposes
you-discoverathttps://api.you.com/mcp. - Check whether the You.com Docs MCP tool
searchDocsis available athttps://you.com/docs/_mcp/server. - If either server is missing, connect or install the missing MCP server(s): provide the server name, URL, and auth requirement from the
metadata.mcp_serversfield in the frontmatter above; point to the MCP setup mechanism for the current agent or MCP client; do not connect or install or modify configuration without approval. - Once both
you-discoverand Docs MCP are available, enter the planning loop: useyou-discoverto explore candidate resources for the target, draft a plan naming the selected resource and why it fits, then return to Docs MCP to verify auth, install, and setup steps before recommending.
Discovery workflow
- Restate the integration target, for example "Pi", "OpenCode", "LangChain", "Vercel AI SDK", "Claude", or "Cursor".
- When available, use
you-discoverto search You.com's AI Catalog, and any catalogs it links to when supported, for resources that match the target task. - Use
searchDocsto verify official You.com docs for API References, MCP setup, Python SDK, auth, and install commands. - Compare available
you-discoverresults and docs, then recommend the smallest integration path. - If no discovered resource fits, recommend a small direct API script or thin MCP bridge rather than reimplementing catalog crawling in the skill.
When planning paid direct API or MCP integrations, keep payment protocol guidance endpoint-specific: search and contents use x402 for keyless paid retries, while research and finance research can use MPP or x402.
Planning loop
Use you-discover and Docs MCP as part of the integration planning loop, not as a one-time preflight check:
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

you-discover is a skill published in the GitHub repository youdotcom-oss/agent-skills (67 stars, last pushed today), licensed MIT. It adds 25 tokens to every session and 1,170 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
object-modify
Modify a Unity UnityEngine.Object's serializable fields/properties. Three modification surfaces are available (objectDiff, pathPatches, jsonPatch) — see the skill body. Use 'object-get-data' first to inspect the object structure.
assets-get-data
Get asset data from the asset file in the Unity project — every serializable field and property. Supports token-saving path-scoped reads via paths or viewQuery. Use 'assets-find' to find the asset first.
editor-selection-get
Get information about the current Selection in the Unity Editor — active object, active transform, selected GameObjects, transforms, instance IDs, and asset GUIDs (each enrichment is opt-in). Pair with 'editor-selection-set' to change the selection.
gameobject-create
Create a new GameObject in the currently opened Prefab or active Scene, optionally parented under another GameObject and pre-positioned. Pass primitiveType to spawn a Unity primitive (Cube, Sphere, etc.) instead of an empty GameObject.
object-get-data
Get serialized data for a Unity UnityEngine.Object — all serializable fields and properties. Supports token-saving path-scoped reads via paths or viewQuery. Pair with 'object-modify' when you need to write back.
unity-skill-create
Create a new skill (MCP tool) for the Unity Editor by writing a C# (.cs) file that Unity compiles into the project. After compilation the new tool becomes callable through MCP. The file must be a partial class decorated with [AiToolType], each tool method must be decorated with [AiTool], the class name should match…
