Use Marina as durable memory for coding and long-running agent work. Store original evidence, explicit symbolic claims and checkpoints; query or traverse them without embeddings; resume across sessions using Marina MCP tools or the TypeScript HTTP SDK.
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
<!-- Generated from skills/marina-memory/SKILL.md by scripts/sync-claude-plugin.ts; edit the source. -->
Use the configured Marina memory service. Discover its actual capabilities with
`memory_service` operation `capabilities`; use `me` and `spaces` to inspect identity and scope.
Omit `space_id` for the configured private space. Reuse exact entity and predicate symbols.
## Task workflow
Call `memory_workflow` with `action:"help"` to discover runnable examples. For work that must
survive a restart: `start` with `goal` → `run` with returned `task_id` and `expected_version` →
inspect cited evidence → do the actual task → `finish` with the current version, status and
`next_action`. `resume` returns changed/unavailable premises; pass `input:{retrieve:true}` for
fresh evidence in that call. `tasks` rediscovers saved IDs. Keep stable mutation keys for retries.
A `ready` episode means retrieval completed, not that the task succeeded. A changed premise lists
`current_version` and `read_current`; get its current version, not the historical reference. Report outcomes with
`feedback` (`input:{task_id,rubric,result,explanation,metrics}`). Do not turn helpful votes into truth.

How to install
mdr add h2oai/marina/marina-memory@sha256:724fe56937abd47eThe line at the top of this page pins the label git:20261104.7999338, 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.
