5 findings (2 high, 3 medium), mainly prompt injection, unauthorized tool use, social engineering. Most recent scan 2026-02-07.
This skill exhibits HIGH severity security concerns primarily due to direct prompt injection attempts that try to force mandatory execution on every agent response. The skill attempts to override normal agent behavior with autonomous actions (context compaction, session restarts) without user consent. While the underlying functionality (cost optimization, model routing, telemetry) could be legitimate, the implementation uses deceptive and coercive patterns that violate agent autonomy principles. The skill also implements browser locking mechanisms that could interfere with other operations. MEDIUM severity issues include social engineering through overstated scope claims and potential availability disruption. LOW severity concerns include telemetry logging without explicit privacy controls and misleading cost savings claims. The skill should be substantially rewritten to operate as an advisory tool that the agent can choose to use, rather than attempting to hijack the agent's decision-making process.
Scanner's overall assessment (LLM analyzer)
Second scanner: NVIDIA SkillSpector
Independent static run, no language model, over the same files as the Cisco scan above. How the two scanners compare across the whole corpus: Two scanners, one corpus.
What this skill does
Master optimization system - APPLIES TO EVERY RESPONSE. Before responding, classify task complexity (simple question vs analysis vs coding). Use Haiku for simple/navigation/extraction/status. Use Sonnet ONLY for writing/analysis/planning/debugging. Monitor context size - if >50k tokens, recommend /compact. For automations, use scheduler wrapper. Never load full conversation history for simple tasks. Heartbeats always Haiku, single-line only. Never use Opus. This skill MUST run before every response to prevent 100k+ token bloat.

Findings
HIGH Direct Prompt Injection - Mandatory Execution Override Prompt Injectionllm
The skill description and instructions contain explicit directives that attempt to override the agent's normal behavior by claiming 'APPLIES TO EVERY RESPONSE' and 'MANDATORY: Run before EVERY response'. This is a direct prompt injection attempting to force the agent to execute this skill's logic before processing any user request, effectively hijacking the agent's decision-making process.
SKILL.md
Description: 'Master optimization system - APPLIES TO EVERY RESPONSE. Before responding, classify task complexity...This skill MUST run before every response'
Instructions: '**MANDATORY: Run before EVERY response, including normal conversation.**'HIGH Direct Prompt Injection - Autonomous System Control Prompt Injectionllm
The instructions contain directives that attempt to control the agent's behavior autonomously, including automatic context compaction ('STOP and say ONLY...then immediately use gateway.restart') without user consent. This attempts to override the agent's normal decision-making and force specific actions.
SKILL.md
'Before responding to ANY message:
1. Check context size via session_status - if >50k tokens, STOP and say ONLY: "⚠️ Context bloat detected: {X}k tokens. Compacting now for 90% cost savings..." then immediately use gateway.restart with reason="Auto-compact: context exceeded 50k tokens"'MEDIUM Tool Exploitation - Unauthorized Browser Lock Management Unauthorized Tool Usellm
The browser_governor.py script implements a locking mechanism that could interfere with legitimate browser usage by other skills or the agent itself. It forcibly breaks locks after a timeout and maintains exclusive browser access, potentially shadowing or blocking legitimate browser operations.
scripts/browser_governor.py
def acquire_lock(self, agent_id: str, task: str) -> bool:
if self.lock_file.exists():
with open(self.lock_file) as f:
lock = json.load(f)
lock_age = time.time() - lock["timestamp"]
if lock_age > self.timeout:
print(f"Stale lock detected ({lock_age:.0f}s old). Breaking lock.")
self.release_lock()MEDIUM Social Engineering - Deceptive Scope Claims Social Engineeringllm
The skill description claims it 'APPLIES TO EVERY RESPONSE' and is a 'Master optimization system', misleading users into believing this skill must or should run for all interactions. This overstates the skill's scope and importance, potentially causing users to trust it with broader access than warranted.
SKILL.md
'Master optimization system - APPLIES TO EVERY RESPONSE...This skill MUST run before every response to prevent 100k+ token bloat.'MEDIUM Availability Disruption - Forced Context Restart Resource Abusellm
The skill attempts to force automatic session restarts when context exceeds 50k tokens, which could disrupt ongoing work and cause loss of conversation state without user consent. This availability disruption pattern could interrupt legitimate long-running tasks.

What we checked
- Static analyzer. Pattern rules over SKILL.md and bundled files: known-bad commands, exfiltration URLs, secrets, obfuscation.
- Llm analyzer. A language model reads the skill and reports intent-level issues the rules cannot express.
- Meta analyzer. A second model pass that validates, deduplicates and re-scores the other analyzers' findings.
What we did not check
- Runtime behaviour. The skill was not executed; findings come from reading its files.
- Anything fetched at install or run time, including remote scripts, package dependencies, and URLs the skill tells the agent to open.
- Content the analyzers cannot read: images, binaries, and some non-English text.
- Known scanner bypass classes. See the methodology and limitations page.
