Search, browse and add lessons in the local CC Commander knowledge base: recent lessons, topic search, category view, stats and file-edit captures. Use when the user asks what we learned, wants past lessons, the knowledge base, or types /ccc-knowledge.
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
# /ccc-knowledge — search what we learned
**CC Commander** · /ccc-knowledge · past lessons from `<config dir>/commander/knowledge/` (`~/.claude/commander/knowledge/` by default; the config dir is `CCC_CONFIG_DIR`, then `CLAUDE_CONFIG_DIR`, then `~/.claude`), searchable in one step.
> Placeholders like ~~knowledge base refer to connected tools. See [CONNECTORS.md](../../CONNECTORS.md).
## When to use / when not to
- Use to recall lessons before a similar task, review outcomes by category, or record a lesson by hand.
- Use `/ccc-recall` to search past session transcripts, and `/ccc-memory` for project memory in `CLAUDE.md` and `memory/`. This skill reads only the Commander knowledge directory.
## What the directory holds
| File | Written by | Used here |
|---|---|---|
| `kl-<epoch-ms>.json` | the CC Commander CLI (`commander/knowledge.js`) after a dispatched task, or "Add a lesson" below | lessons: `timestamp`, `task`, `outcome`, `category`, `keywords`, `patterns.{techStack, successPatterns, errorPatterns}` |
| `session-*.json` | the plugin SessionEnd hook | session stubs (`sessionId`, `startedAt`, `endedAt`); counted, not shown as lessons |

How to install
mdr add kevinzai/commander/ccc-knowledge@sha256:cc077c2da049fbebThe line at the top of this page pins the label git:20261025.7eae921, 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.
