Maintain and update product knowledge base from releases, features, and project changes with optional wiki sync.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# COG Update Knowledge Base Skill ## When to Invoke - After a release — update product knowledge with new features and changes - User says "update knowledge base", "update KB", "sync knowledge", "update product docs" - Periodic maintenance — ensure knowledge base reflects current product state - After major feature launches, architecture changes, or deprecations ## Agent Mode Awareness **Check `agent_mode` in `00-inbox/MY-PROFILE.md` frontmatter:** - If `agent_mode: team` — use parallel agents to scan multiple sources and update multiple knowledge files simultaneously - If `agent_mode: solo` — process updates sequentially, one knowledge file at a time ## Command: `/update-knowledge-base` ## Pre-Flight Check 1. **Read `00-inbox/MY-INTEGRATIONS.md`** for active data sources and publishing targets 2. **Read `00-inbox/MY-PROFILE.md`** for active projects 3. **Get current timestamp:** Run `date '+%Y-%m-%d %H:%M'` using Bash 4. **Scan existing knowledge base:** Glob `05-knowledge/**/*.md` to understand current state --- ## Execution Strategy ### Phase 1: Determine Update Scope Ask the user (or infer from context): ``` What triggered this knowledge base update? …

How to install
mdr add huytieu/cog-second-brain/update-knowledge-base@sha256:e5f480eb9d2cfff9The line at the top of this page pins the label git:20260807.b852369, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
