customize

customize is a skill for Claude Code, Codex from UnicomAI/wanwu. It costs 88 tokens per session (5,336 once invoked), scanned A, original, Apache-2.0.

A workflow for creating and maintaining custom AI agent profiles and skills through a programming interface. Profiles bundle an agent's identity, description, available skills, and connector access.

In plain words
What is it for?
Use it to create agents, author skills, modify capabilities, attach or remove skills and connectors, and inspect available tools.
Why use it?
It removes the need to configure these profiles manually and makes their capabilities easier to inspect and change consistently.

    Skill modifies its own code, configuration, or behavior at runtime. Self-modification enables an agent to escalate privileges, disable safety constraints, or install persistent backdoors.
    Fix: Prevent the skill from modifying its own code, SKILL.md, or configuration files. Treat skill files as read-only at runtime.

Token cost

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.

Security

Grade A, and why

customize scanned grade A with 1 finding 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 458 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Customize

Build and maintain agent profiles and skills programmatically via the repl tool using host.agents.* and host.skills.*.

A profile is a named bundle that shapes how an agent behaves:

  • system_prompt — the profile's identity. This is the opening of the agent's system prompt; it REPLACES the generic "You are Claude Science" base identity. Write it in second person, lead with You are {display_name}, ..., state what the agent specializes in and what it does NOT do. Everything else (tool-usage rules, working-style bullets, scope guardrail) is inherited automatically — don't restate it.
  • display_name / description / icon_key / color_key — picker metadata.
  • skill_names (optional restriction) — by default a profile sees the full live skill catalog via search_skills / skill(...), same as the main agent. Pass an explicit list ONLY to deliberately restrict it; [] creates a zero-skill specialist. Restricting skills also restricts connectors — a single unrestricted flag governs both; passing skill_names flips the profile to curated mode and starts it with zero connectors (see next).
  • Connector access — an unrestricted profile (the default) reaches every connector (bundled + custom + authorized directory), same as the main agent; use detach_connector to subtract specific ones. A curated profile (one created with an explicit skill_names list, or flipped via {"unrestricted": False}) starts with no connectors — reach is exactly what you attach_connector.
  • excludedTools — per-tool blocklist applied after connectors resolve. Use to strip specific high-risk or irrelevant tools from an otherwise-useful connector. Per-connector, not a profile field — set via attach_connector(..., include_tools_pattern=/exclude_tools_pattern=); the profile's excludedTools in list() is the read-only aggregation across all its attached connectors. Patterns match the connector's bare tool names (e.g. '^list_marts$', as returned by list_connectors(name)['tools']); the aggregated excludedTools entries are stored fully-qualified as mcp_<connector>_<tool> since the list spans every attached connector.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

customize is a skill published in the GitHub repository UnicomAI/wanwu (2,371 stars, last pushed 3d ago), licensed Apache-2.0. It adds 88 tokens to every session and 5,336 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
