What it does
Hindsight Recall is an agent skill from vectorize-io/hindsight. Search long-term memory for relevant context from past coding sessions using Hindsight MCP tools
Its SKILL.md is about 310 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 and MCP servers. The repository describes itself as: Hindsight: Agent Memory That Learns. The licence is MIT.
When your agent uses it
- Tasks that involve Agent memory
- Tasks that involve MCP servers
Example prompts
- “/hindsight-recall”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Identify the key topic or question from the user's request.
- Check if in the current context already contains relevant results from the automatic session-start recall.
- If session memory already covered it, use those memories directly.
- If the user needs more specific or deeper recall, use the Hindsight MCP recall tool to search for additional memories.
- If you want to reason over accumulated memories for architectural decisions, use the reflect tool.
What it can do on your machine
Read from SKILL.md and the folder at commit 9269b88. 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
Hindsight Recall loads about 312 tokens when it runs. Until then it costs about 28 tokens; SKILL.md has 161 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.

Hindsight Recall
Trigger
Use when the user explicitly asks about past decisions, project context, preferences, or anything that may have been discussed in prior sessions.
Workflow
- Identify the key topic or question from the user's request.
- Check if
<hindsight_memories>in the current context already contains relevant results from the automatic session-start recall. - If session memory already covered it, use those memories directly.
- If the user needs more specific or deeper recall, use the Hindsight MCP
recalltool to search for additional memories. - If you want to reason over accumulated memories for architectural decisions, use the
reflecttool.
Guardrails
- Only use MCP tools for deeper recall when the session-start memory was insufficient.
- When memories conflict with current context, prefer current context and note the discrepancy.
- Do not expose raw memory metadata to the user unless asked.
Output
- Relevant memories integrated into the response
- If MCP tools are not available, advise the user to check their
