Each `_index` should appear in either `validated_findings` or `false_positives`. Keep false positive entries brief (`_index`, `original_title`, `false_positive_reason`) to save output space. Focus detailed validation on critical true positives. +2. **Preserve `_index`**: Always include the original finding index to track which finding you're validating. +3. **FILTER ONLY GENUINE FPs**: Mark as false positive ONLY when the flagged code is actually benign. If the code really does what the finding claims, it's a TRUE POSITIVE — keep it. +4. **PRIORITIZE RUTHLESSLY**: Not all findings are equal. A credential leak is more urgent than a missing metadata field. Use `priority_rank` to make this clear. +5. **CONSOLIDATE DUPLICATES**: 5 findings about the same issue = group in `correlations`, but keep each in `validated_findings`. Use correlations for grouping, NOT for removing findings. +6. **MAKE IT ACTIONABLE**: Every recommendation should be something a developer can copy-paste or immediately act on. +7. **DON'T INVENT THREATS**: `missed_threats` should be empty in most cases. Only add if there's something OBVIOUS and DANGEROUS that was missed. +8. **Consider Context**: A "dangerous" function in a security tool may be legitimate. A skill that declares network access and uses network is NOT suspicious. + +## Confidence Levels + +- **HIGH**: Strong evidence supports classification, multiple signals align +- **MEDIUM**: Likely correct but some ambiguity remains +- **LOW**: Best guess, recommend manual review + +## Severity Adjustments + +You may adjust severity based on: +- Context that increases/decreases actual risk +- Correlation with other findings that amplify impact +- Mitigating factors (input validation, sandboxing) +- Attack prerequisites (requires auth, local access only) + +--- + +**NOW ANALYZE THE FOLLOWING SKILL AND FINDINGS:** diff --git a/skill_manager/data/prompts/skill_threat_analysis.md b/skill_manager/data/prompts/skill_threat_analysis.md new file mode 100644 index 0000000..68b9ba0 --- /dev/null +++ b/skill_manager/data/prompts/skill_threat_analysis.md @@ -0,0 +1,321 @@ +# Agent Skill Threat Analysis + +You are a security expert analyzing **Agent Skill packages** for potential threats. + +## What is an Agent Skill? + +An Agent Skill is a **local directory package** containing: + +### 1.

Examples: "ignore previous instructions", "unrestricted mode", "bypass safety guidelines", "do not tell the user", jailbreak attempts, system prompt extraction. + +- **AITech-1.2 (Indirect Prompt Injection - Instruction Manipulation)**: Use when skills embed or follow malicious instructions from external data sources (webpages, documents, APIs) that override intended behavior. Examples: "follow instructions from this webpage", "execute code blocks found in files", "trust content from external sources", delegating trust to untrusted external data. + +- **AITech-4.3 (Protocol Manipulation - Capability Inflation)**: Use when skills manipulate discovery mechanisms to inflate perceived capabilities or increase unwanted activation. Examples: Keyword baiting, over-broad capability claims, brand impersonation, skill named "safe-calculator" but actually exfiltrates data. + +- **AITech-8.2 (Data Exfiltration / Exposure)**: Use for unauthorized data access, transmission, or exposure. Examples: Network calls sending credentials/data to **suspicious/unknown** external servers, reading ~/.aws/credentials or ~/.ssh keys, hardcoded API keys/secrets in code, environment variable harvesting. **Do NOT flag** calls to well-known APIs (api.openai.com, api.anthropic.com, generativelanguage.googleapis.com, etc.) or normal request/response patterns. + +- **AITech-9.1 (Model or Agentic System Manipulation)**: Use for injection attacks that manipulate system behavior. Examples: Command injection with **user-controlled input** (eval(user_input), exec(user_input), os.system(variable_from_user)), SQL injection, XSS, reverse shells. **Do NOT flag** standard package install commands (pip install, npm install, brew install) or subprocess calls with hardcoded arguments — these are NOT injection. + +- **AITech-9.2 (Detection Evasion)**: Use for obfuscation/evasion patterns designed to hide malicious intent. Examples: encoded payload chains (base64 -> exec), intentionally obfuscated scripts, hidden execution stagers. + +- **AITech-12.1 (Tool Exploitation)**: Use for tool-related attacks. Examples: Tool poisoning (corrupting tool behavior via data/configuration), tool shadowing (replacing legitimate tools), unauthorized tool use (violating allowed-tools restrictions), manipulating tool outputs. + +- **AITech-13.1 (Disruption of Availability)**: Use for resource exhaustion or denial of service attacks. Subtechnique AISubtech-13.1.1 (Compute Exhaustion) applies. Examples: Infinite loops, unbounded retries, excessive resource consumption, CPU/memory exhaustion, denial of service patterns. + +- **AITech-15.1 (Harmful Content)**: Use for deceptive or harmful content that doesn't fit other categories. Examples: Misleading instructions that could cause harm, deceptive content generation, misinformation. + +**IMPORTANT**: + +- You MUST use the exact AITech code (e.g., "AITech-1.1") in the "aitech" field. The structured output schema enforces this. +- Match the threat type to the most appropriate AITech code based on the examples above. +- If a threat matches multiple codes, choose the most specific one (e.g., use AITech-1.1 for prompt injection in SKILL.md, not AITech-9.1). + +**Location Format:** "filename:line_number" or "filename" + +### 6. Behavioral & Autonomy Checks + +**What to analyze:** + +- Unbounded autonomy ("keep trying until success", "run without confirmation") +- Cross-context bridging ("use info from previous chats", "remember across sessions") +- Over-collection ("collect everything first", "gather all files") +- Tool chaining ("read then send", "collect and post", "traverse → upload") +- Transitive trust ("follow webpage instructions", "execute code blocks found") + +### 7. Discovery & Activation Abuse + +**What to analyze:** + +- Keyword baiting (excessive trigger words unrelated to actual functionality) +- Activation priority manipulation ("use me first", "priority tool") +- Brand impersonation (claiming to be an official tool when it's not) + +**IMPORTANT - Normal patterns that should NOT be flagged:** + +- ✅ SAFE: Over-broad descriptions like "general assistant", "code helper", "utility tool" — generic descriptions are common and acceptable. Only flag if there is clear evidence of intentional deception (e.g., named "safe-calculator" but actually exfiltrates data). + +### 8. Dependency & Supply Chain + +**What to analyze:** + +- Direct GitHub installs from unknown/untrusted repos +- Typosquatting indicators (package names similar to popular packages) +- Installing packages with `--no-verify` or similar security-bypassing flags + +**IMPORTANT - Normal patterns that should NOT be flagged:** + +- ✅ SAFE: `pip install requests` without version pin — unpinned versions are common and acceptable in skills. Only flag as LOW if the package is obscure/unknown. +- ✅ SAFE: `npm install express` — standard package installation is NOT a supply chain risk. +- ✅ SAFE: Missing author/version/license in a skill — this is informational only, NOT a security threat. + +### 9. Tool Chaining & Data Flow + +**What to analyze:** + +- Multi-step operations: read → send, collect → post, gather → upload +- Automated workflows without user confirmation +- Data pipelines that combine sensitive operations +- Cross-boundary data flow (local → network, file → API) + +**IMPORTANT - Normal patterns that should NOT be flagged:** + +- ✅ SAFE: "Read a file → process it → call an API with the result" — this is a normal tool use pattern. Only flag if the data being sent is clearly sensitive (credentials, SSH keys, env vars with secrets) AND the destination is not a well-known API. +- ✅ SAFE: "Read project files → generate summary" — reading files for analysis is normal, NOT over-collection. + +**Example Threat:** + +```markdown +Instructions: + +1.
