CogSig IDE

Cognitive Signature IDE — a Claude Code plugin that syncs Claude to your cognitive signature and keeps it aligned as you change. https://github.com/Choppaaahh/cognitive-signature-ide Two functionalities on one pipeline: 1. Voice signature — 7 dimensions of how you direct AI (directive style, compression, reframe patterns, trust signals, idiomatic tells, iteration cadence, texture energy). Extracted from raw user-typed directives across your Claude Code JSONL corpus. 2. Operational signature — 4 dimensions of what you've learned through usage (recurring_decision_templates / recurring_failure_patterns / recurring_tooling_invocations / vocabulary_anchors). Auto-promoted to a permanent signature when n≥2 instances observed. Four onboarding presets (normie / power / team / enterprise) map to three deploy modes (standalone / team-shared / cloud-governed). Hands-off by default; user surfaced only on conflict. Ships 3 dual-function governance subagents — brutus (Opus, adversarial), qa (Haiku, schema/compile/dead-code), historian (Sonnet, drift tracking) — across two substrates (in-session Claude Code plugin + API-level Managed Agents). Same architecture, different persistence. Measurement: 100% auto-scorer accuracy on N=10 blind tests (Claude-as-judge) = +66.7pp over chance, 5-persona simulation grid showing same pipeline produces visibly-distinctsignatures, 5 real governance catches during this build cataloged (QA caught 3 plugin-loader schema violations pre-demo; Brutus caught 3 contaminated blind-test prompts before 30 Opus calls fired; and more).
