From 2c61fb69c1cca5ea46136fe71ade96efba1a2e45 Mon Sep 17 00:00:00 2001 From: theonejvo <125909656+theonejvo@users.noreply.github.com> Date: Tue, 17 Feb 2026 02:26:41 +1100 Subject: [PATCH] feat(security): add client-side skill security enforcement MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add a capability-based security model for community skills, inspired by how mobile and Apple ecosystem apps declare capabilities upfront. This is not a silver bullet for prompt injection, but it's a significant step up from the status quo and encourages responsible developer practices by making capability requirements explicit and visible. Runtime enforcement for community skills installed from ClawHub: - Capability declarations (shell, filesystem, network, browser, sessions) parsed from SKILL.md frontmatter and enforced at tool-call time - Static SKILL.md scanner detecting prompt injection patterns, suspicious constructs, and capability mismatches - Global skill security context tracking loaded community skills and their aggregate capabilities - Before-tool-call enforcement gate blocking undeclared tool usage - Command-dispatch capability check preventing shell/filesystem access without explicit declaration - Trust tier classification (builtin/community/local) — only community skills are subject to enforcement - System prompt trust context warning for skills with scan warnings or missing capability declarations - CLI: `skills list -v`, `skills info`, `skills check` now surface capabilities, scan results, and security status - TUI security log panel for skill enforcement events - Docs updated across 7 files covering the full security model Companion PR: openclaw/clawhub (capability visibility + UI badges) --- CHANGELOG.md | 2 + docs/cli/security.md | 54 +++ docs/cli/skills.md | 162 ++++++- docs/gateway/security/index.md | 14 +- docs/tools/clawhub.md | 22 +- docs/tools/creating-skills.md | 20 +- docs/tools/skills.md | 202 ++++++++- src/agents/pi-tools.before-tool-call.ts | 15 + src/agents/skills-status.ts | 8 +- src/agents/skills/frontmatter.ts | 14 + src/agents/skills/types.ts | 33 ++ src/agents/skills/workspace.ts | 106 ++++- src/agents/system-prompt.ts | 19 +- src/agents/tool-policy-shared.ts | 2 + src/cli/skills-cli.format.ts | 420 ++++++++++++++---- src/cli/skills-cli.ts | 46 +- src/security/dangerous-tools.ts | 61 +++ src/security/skill-scanner.ts | 226 ++++++++++ src/security/skill-security-context.ts | 142 ++++++ ui/src/styles/components.css | 6 + ui/src/ui/app-render.ts | 2 + ui/src/ui/app-view-state.ts | 1 + ui/src/ui/app.ts | 1 + ui/src/ui/controllers/logs.ts | 28 +- ui/src/ui/types.ts | 12 + ui/src/ui/views/agents-panels-tools-skills.ts | 2 + ui/src/ui/views/logs.ts | 23 +- ui/src/ui/views/skills-shared.ts | 46 +- ui/src/ui/views/skills.ts | 2 + 29 files changed, 1571 insertions(+), 120 deletions(-) create mode 100644 src/security/skill-security-context.ts diff --git a/CHANGELOG.md b/CHANGELOG.md index 70185653ff1..8ed3e46781e 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -10,6 +10,8 @@ Docs: https://docs.openclaw.ai - Discord/Allowlist: canonicalize resolved Discord allowlist names to IDs and split resolution flow for clearer fail-closed behavior. - Memory/FTS: add Korean stop-word filtering and particle-aware keyword extraction (including mixed Korean/English stems) for query expansion in FTS-only search mode.
