What it does

Hindsight Local is an agent skill from vectorize-io/hindsight. Store user preferences, learnings from tasks, and procedure outcomes. Use to remember what works and recall context before new tasks. (user)

Its SKILL.md is about 1.1k 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. The repository describes itself as: Hindsight: Agent Memory That Learns. The licence is MIT.

When your agent uses it

  • Remember what works and recall context before new tasks

Example prompts

  • “/hindsight-local”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Extracts structured facts from the content using an LLM
  2. Identifies entities (people, tools, concepts) and links related facts
  3. Builds temporal and causal relationships between facts
  4. Generates embeddings for semantic search

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

    Shell commands in SKILL.md call:

    • uvx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use uvx, which can reach the network depending on how they are called.

    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 Local loads about 1.1k tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 380 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~39
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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 Memory Skill (Local)

You have persistent memory via the hindsight-embed CLI. Proactively store learnings and recall context to provide better assistance.

Setup Check (First-Time Only)

Before using memory commands, verify Hindsight is configured:

bash
uvx hindsight-embed daemon status

If this fails or shows "not configured", run the interactive setup:

bash
uvx hindsight-embed configure

This will prompt for an LLM provider and API key. After setup, the commands below will work.

How Hindsight Works

When you call retain, Hindsight does not store the string as-is. The server runs an internal pipeline that:

  1. Extracts structured facts from the content using an LLM
  2. Identifies entities (people, tools, concepts) and links related facts
  3. Builds temporal and causal relationships between facts
  4. Generates embeddings for semantic search

This means you should pass rich, full-context content — the server is better at extracting what matters than a pre-summarized string. Your job is to decide when to store, not what to extract.

Commands

Store a memory

Use memory retain to store what you learn. Pass the full context — raw observations, session notes, conversation excerpts, or detailed descriptions:

bash
uvx hindsight-embed memory retain default "User is working on a TypeScript project. They enabled strict mode and prefer explicit type annotations over inference."
uvx hindsight-embed memory retain default "Ran the test suite with NODE_ENV=test. Tests pass. Without NODE_ENV=test, the suite fails with a missing config error." --context procedures
uvx hindsight-embed memory retain default "Build failed on Node 18 with error 'ERR_UNSUPPORTED_ESM_URL_SCHEME'. Switched to Node 20 and build succeeded." --context learnings

You can also pass a raw conversation transcript with timestamps:

bash
uvx hindsight-embed memory retain default "[2026-03-16T10:12:03] User: The auth tests keep failing on CI but pass locally. Any idea?
[2026-03-16T10:12:45] Assistant: Let me check the CI logs. Looks like the tests are running without the TEST_DATABASE_URL env var set — they fall back to the production DB URL and hit a connection timeout.
[2026-03-16T10:13:20] User: Ah right, I never added that to the CI secrets. Adding it now.
[2026-03-16T10:15:02] User: That fixed it. All green now." --context learnings
Recall memories

Use memory recall BEFORE starting tasks to get relevant context:

bash
uvx hindsight-embed memory recall default "user preferences for this project"
uvx hindsight-embed memory recall default "what issues have we encountered before"
Reflect on memories

Use memory reflect to synthesize context:

bash
uvx hindsight-embed memory reflect default "How should I approach this task based on past experience?"

IMPORTANT: When to Store Memories

Always store after you learn something valuable:

User Preferences
  • Coding style (indentation, naming conventions, language preferences)
  • Tool preferences (editors, linters, formatters)
  • Communication preferences
  • Project conventions
Show full SKILL.md (145 more words)Show less
Procedure Outcomes
  • Steps that successfully completed a task
  • Commands that worked (or failed) and why
  • Workarounds discovered
  • Configuration that resolved issues
Learnings from Tasks
  • Bugs encountered and their solutions
  • Performance optimizations that worked
  • Architecture decisions and rationale
  • Dependencies or version requirements

IMPORTANT: When to Recall Memories

Always recall before:

  • Starting any non-trivial task
  • Making decisions about implementation
  • Suggesting tools, libraries, or approaches
  • Writing code in a new area of the project

Best Practices

  1. Store immediately: When you discover something, store it right away
  2. Pass rich context: Include full observations, not pre-summarized strings — the server extracts facts automatically
  3. Include outcomes: Store what happened AND why, including failures and workarounds
  4. Recall first: Always check for relevant context before starting work
  5. Use --context for metadata: The --context flag labels the type of memory (e.g., procedures, learnings, preferences), not a replacement for full content
