At a glance
Save what was learned to Hindsight long-term memory. An agent skill from vectorize-io/hindsight.
- Works in 3 steps: Decide where it belongs → Write a short, self-contained note that… → Call retain with that note as content,…
- A task finishes
- SKILL.md covers Steps and Rules
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
Memory Retain is an agent skill from vectorize-io/hindsight. Save what was learned to Hindsight long-term memory. Use when a task finishes, when the user states a fact, decision or preference, and when you discover something a later run or another Bot would need.
Its SKILL.md is about 290 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows, covering Agent memory. The repository describes itself as: Hindsight: Agent Memory That Learns. The licence is MIT.
When your agent uses it
- A task finishes
- The user states a fact
- When you discover something a later run
- Another Bot would need
Example prompts
- “/memory-retain”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Decide where it belongs
- Write a short, self-contained note that makes sense with no other context: what happened or was decided, who decided it, when, and why…
- Call retain with that note as content, and tags of source:grok-bot and bot:.
What it can do on your machine
Read from SKILL.md and the folder at commit fb11ddf. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Memory Retain loads about 294 tokens when it runs. Until then it costs about 54 tokens; SKILL.md has 153 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- memory-retain
- description
- Save what was learned to Hindsight long-term memory. Use when a task finishes, when the user states a fact, decision or preference, and when you discover something a later run or another Bot would need.
Save what was learned
Memory is only useful if the next run can find it. Save the outcome and the reason, not a transcript.
Steps
- Decide where it belongs:
- Only useful to this Bot's own work: this Bot's bank,
grok-bot::<bot-name>. - Useful to any Bot, or a fact about the user:
grok-bot::shared.
- Only useful to this Bot's own work: this Bot's bank,
- Write a short, self-contained note that makes sense with no other context: what happened or was decided, who decided it, when, and why. "On 3 Oct the user chose Vendor B over Vendor A because A has no EU data residency" beats "user picked B".
- Call
retainwith that note ascontent, andtagsofsource:grok-botandbot:<bot-name>.
Rules
- One note per distinct fact or decision. Do not paste whole conversations or tool output.
- Never store passwords, one-time codes, API keys, card or account numbers, or health measurements.
- Never write to banks that belong to the user's other tools.
