This skill should be used when the user wants to "synthesize two competing solutions without averaging", "resolve a design/value disagreement by lifting to a higher frame", "止揚 / アウフヘーベン", "矛盾を止揚", "独立案を統合", "平均化せず統合", "contradiction lift", "sublate competing designs", or has two good-but-divergent answers to the same question and wants a higher-order resolution (a selection mechanism) or an honest aporia — not a compromise. NOTE: Use this when two independent solutions diverge and you want to PRESERVE both truth-moments while lifting to a higher frame. Use devils-advocate to stress-test ONE proposal with an assigned opponent, strong-inference to find an unknown cause, and dialectic-loop to validate a claim against a real corpus.

Analyze an idea, proposal, change, claim, or decision from facts through problem, value, mechanism, consequences, evidence, alternatives, and action. Use when the user asks what something is for, why it matters, whether it is worth doing, what impact it has, or how to decide. Do not use for simple factual lookup or straightforward execution.

Finds where every credential on the machine lives, without showing a value. Trigger to list where keys, tokens and passwords are stored (Credential Manager, gh, .env, settings, .mcp.json, Docker); to cut a gh token to least privilege or switch gh accounts; to rotate a key and update its users; after a key was printed, pasted or committed; to check a command that uses a token before it runs; or say keywarden (inventory, scope, rotate, leak, preflight, refresh). Drives op or bw when present. Leak scans and commit email are shieldwarden's; rules and hooks gatewarden's; routine credentials agentwright's; vetting a vault MCP trustwarden's.
