Creates YAML policies that control which MCP tools each agent can see and call. Use when user mentions token costs, context window bloat, too many tools, tool scoping, reducing tokens, saving money on API calls, least privilege, restricting tool access, creating access policies, or agent permissions. Also when user says \"my context window is full\" or \"too many tool schemas\" or \"MCP is too expensive\".","version":"","author":null,"license":"","compatibility":"","status":"completed","overallGrade":"B","scannerVersion":1,"fileCount":0,"hasSkillMd":false,"hasScripts":false,"hasReferences":false,"hasEvals":false,"hasAssets":false,"sourceType":"cli","sourceUrl":"","createdAt":"2026-07-17T03:22:17.486Z","completedAt":"2026-07-17T03:22:15.787Z","visibility":"public","publishedAt":"2026-07-28T14:39:04.568Z","category":"","frameworks":[],"badgeStatus":"conditional","downloadCount":0,"verdictRationale":null,"verdictPolicyVersion":null,"skillId":"cmrodgpwl0d7mad082qbgq0ih","findings":[{"id":"cmrodgrx70fqiad083b3qwfpl","source":"vettd","category":"security","label":"References external URL — review for indirect prompt injection risk","detail":"External URL(s) detected in SKILL.md — referenced content can change after audit","severity":"medium","ruleId":"VTD-0088","owaspLlmCategory":null,"intent":null,"chainId":null,"fingerprint":"885bf1b4de9a77b02bbb1cdf717927d5","filepath":""},{"id":"cmrodgrx70fqhad08ur4sp6a9","source":"vettd","category":"security","label":"No prompt injection or jailbreak signals detected","detail":"Scanned text content for instruction override, jailbreak framing, credential solicitation, and embedded injection markers","severity":"info","ruleId":"VTD-0092","owaspLlmCategory":null,"intent":null,"chainId":null,"fingerprint":"ee5675c6452295fc92108d4c30cfebf6","filepath":""},{"id":"cmrodgrx70fqaad08di1uehsz","source":"vettd","category":"security","label":"No repository link","detail":"No repository field found in SKILL.md frontmatter.
