Risk Summary

Safe With Normal Controls

Dep Visibility is the main signal, but overall risk remains within an acceptable range.

Potential impact: This finding indicates the tool should be reviewed before it is trusted.

Recommended action: No high-risk findings were detected in this scan, but you should still apply least-privilege defaults and rescan after changes.

Suggested policy: keep this tool behind manual approval, do not allow unattended runs, and re-scan after narrowing risky permissions.

Security Findings (30)

  • HighAS-003

    🔀Scope Mismatch ×2

    tool name "fetch_working_example" implies read-only operation but declares exec permission

    fetch_working_example

    tool name "list_known_deprecations" implies read-only operation but declares exec permission

    list_known_deprecations

    Fix: Ensure tool names, descriptions, and permission declarations are internally consistent. Use explicit naming conventions that fully reflect actual capabilities.

  • LowAS-011

    ℹ️Missing Rate-Limit / Timeout ×9

    tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration

    review_framework_coderewrite_framework_codediagnose_framework_errorresolve_symbolfetch_working_examplefetch_latest_syntaxsearch_ai_framework_docsdraft_xrpl_intent_txlist_known_deprecations

    Fix: Declare explicit rate-limit, timeout, and retry configuration for all network and execution tools. Implement exponential back-off and surface resource state to the calling agent.

  • InfoAS-002

    ⚠️Excessive Permissions ×9

    declared capabilities: code/command execution, filesystem access

    review_framework_coderewrite_framework_code

    declared capabilities: code/command execution, network access

    diagnose_framework_error

    declared capabilities: network access

    resolve_symboldraft_xrpl_intent_tx

    declared capabilities: code/command execution, network access, filesystem access

    fetch_working_example

    declared capabilities: network access, filesystem access

    fetch_latest_syntax

    declared capabilities: network access, database access

    search_ai_framework_docs

    declared capabilities: code/command execution

    list_known_deprecations

    Fix: Tool requests broad permissions (exec/fs/network). Validate input parameters using Enums where possible, and restrict file system operations to explicit allowed directories.

  • InfoAS-014

    ℹ️Dependency Inventory Unavailable ×10

    Tool did not expose metadata.dependencies or repo_url, so supply-chain coverage is limited.
