3	Hindsight Agent Memory Skill | AI Coding Assistant Integration	Give AI coding assistants like Claude Code and Codex persistent memory across sessions with Hindsight's Agent Skill — a reusable prompt template for long-term context retention.

Skills

Hindsight provides an Agent Skill that gives AI coding assistants persistent memory across sessions. Skills are reusable prompt templates that agents can load when needed to gain specialized capabilities.

Supported Platforms

Platform	Skills Directory
Claude Code	~/.claude/skills/
OpenCode	~/.opencode/skills/
Codex CLI	~/.codex/skills/

Deployment Modes

The skill supports two deployment modes:

Mode	Best For	Data Location
Local	Individual developers	Your machine (~/.pg0/)
Cloud	Teams sharing knowledge	Hindsight Cloud

Quick Install

Option 1: Interactive Installer (Recommended)

curl -fsSL https://hindsight.vectorize.io/get-skill | bash

The installer will:

1. Prompt you to select your AI coding assistant
2. Select deployment mode (local or cloud)
3. Configure the appropriate settings
4. Install the skill to the appropriate directory

Install for a Specific Platform

# Claude Code (interactive mode selection)
curl -fsSL https://hindsight.vectorize.io/get-skill | bash -s -- --app claude

# OpenCode
curl -fsSL https://hindsight.vectorize.io/get-skill | bash -s -- --app opencode

# Codex CLI
curl -fsSL https://hindsight.vectorize.io/get-skill | bash -s -- --app codex

Install with Cloud Mode

# Direct cloud setup (skips interactive prompts for mode)
curl -fsSL https://hindsight.vectorize.io/get-skill | bash -s -- --app claude --mode cloud

Option 2: Using add-skill

If you use add-skill to manage your agent skills:

# For local mode (individual developers)
npx add-skill vectorize-io/hindsight --skill hindsight-local

# For Hindsight Cloud (teams)
npx add-skill vectorize-io/hindsight --skill hindsight-cloud

# For self-hosted Hindsight servers
npx add-skill vectorize-io/hindsight --skill hindsight-self-hosted

On first use, the AI will guide you through the remaining setup:

• Local: Run uvx hindsight-embed configure to set up your LLM provider
• Cloud: Provide your API key and bank ID
• Self-hosted: Provide your server URL, API key, and bank ID

What the Skill Provides

Once installed, your AI assistant gains the ability to:

• Retain - Store user preferences, learnings, and procedure outcomes
• Recall - Search for relevant context before starting tasks
• Reflect - Synthesize memories into contextual answers

The skill uses the hindsight-embed CLI which runs a lightweight local daemon with an embedded database.

How Skills Work

Skills are model-invoked, meaning the AI assistant automatically decides when to use them based on the context of your conversation. You don't need to explicitly trigger the skill.

The assistant will:

• Store when you share preferences, when tasks succeed/fail, or when learnings emerge
• Recall before starting non-trivial tasks to get relevant context

What Gets Stored

The skill is optimized to store:

Category	Examples
User Preferences	Coding style, tool preferences, language choices
Procedure Outcomes	Commands that worked, configurations that resolved issues
Learnings	Bug solutions, workarounds, architecture decisions

All data stays on your machine. The daemon auto-starts when needed and shuts down after inactivity.

Shared Memory Bank (team-accessible)

Data is stored in Hindsight Cloud and shared across your team. All team members with the same bank ID can access shared memories.

---

Local Mode Setup

The skill uses configuration stored in ~/.hindsight/config.env. Reconfigure anytime:

uvx hindsight-embed configure

---

Cloud Mode Setup

Cloud mode connects to Hindsight Cloud, allowing teams to share memories about a codebase. When one team member learns something, everyone benefits.

Prerequisites

1. A Hindsight Cloud account (sign up)
2. An API key from your team admin
3. A bank ID for your project (e.g., team-acme-frontend)

Installation

Run the installer with cloud mode:

curl -fsSL https://hindsight.vectorize.io/get-skill | bash -s -- --mode cloud

You'll be prompted for:

Setting	Description	Example
Cloud API URL	Hindsight Cloud endpoint	https://api.hindsight.vectorize.io
API Key	Your authentication key	hs_xxx...
Bank ID	Shared memory bank for your team	team-acme-frontend

Configuration Files

Cloud mode creates two files:

~/.hindsight/config — API connection settings (TOML format):

api_url = "https://api.hindsight.vectorize.io"
api_key = "hs_xxx..."

~/.claude/skills/hindsight/SKILL.md — Skill definition with your bank ID baked in.

Team Setup

To set up cloud mode for your team:

1. Team admin creates a bank in Hindsight Cloud (e.g., team-acme-frontend)
2. Team admin generates API keys for each team member
3. Each developer runs the installer with their API key and the shared bank ID
4. All team members now share the same memory bank

What to Store in Team Banks

Cloud mode uses a shared team bank. Be thoughtful about what goes in:

Type	Examples	How to Store
Project conventions	Linting rules, testing requirements, Node version	"Project uses ESLint with Airbnb config"
Team knowledge	Architecture decisions, common pitfalls, domain logic	"Auth module requires Redis 7+"
Individual preferences	Personal coding style, communication preferences	"Alice prefers verbose commit messages"

Key distinction: Project conventions apply to everyone. Individual preferences should include the person's name so the AI knows when to apply them.

Example Workflow

Day 1: Alice discovers a requirement
─────────────────────────────────────
Alice's AI assistant stores:
  "The auth module requires Redis 7+ due to HEXPIRE command usage"
  "Alice prefers explicit error handling over silent failures"

Day 2: Bob starts working on auth
─────────────────────────────────
Bob's AI assistant recalls:
  "The auth module requires Redis 7+ due to HEXPIRE command usage"

Bob avoids the same issue Alice hit!
(Alice's personal preference is stored but won't be applied to Bob)

Testing Cloud Connection

After installation, verify the connection:

# Store a test memory
hindsight memory retain team-acme-frontend "Alice works at Google as a software engineer"

# Recall it
hindsight memory recall team-acme-frontend "Alice"

Switching Between Banks

If you work on multiple projects, you can have different skills installed for each AI assistant, or manually switch banks:

# Environment variable override (temporary)
HINDSIGHT_API_URL=https://api.hindsight.vectorize.io \
HINDSIGHT_API_KEY=hs_xxx \
hindsight memory recall different-bank "query"

For permanent multi-bank setups, reinstall the skill with a different bank ID.

Troubleshooting

Skill not activating

The skill activates based on its description matching your request. Try being explicit:

• "Remember that..." triggers storage
• "What do you know about..." triggers recall

Local Mode Issues

Daemon not starting:

uvx hindsight-embed daemon status
uvx hindsight-embed daemon logs

Reconfigure LLM provider:

uvx hindsight-embed configure

Cloud Mode Issues

Authentication errors:

# Verify your config
cat ~/.hindsight/config

# Test connection manually
hindsight bank list

Wrong bank ID:

Check your SKILL.md file to see which bank ID is configured:

cat ~/.claude/skills/hindsight/SKILL.md | grep "memory retain"

To change the bank ID, reinstall the skill:

curl -fsSL https://hindsight.vectorize.io/get-skill | bash -s -- --mode cloud

Network/firewall issues:

# Test connectivity to cloud API
curl -I https://api.hindsight.vectorize.io/health

Requirements

Local Mode

• Python 3.10+ (for uvx)
• An LLM API key (OpenAI, Anthropic, Groq, etc.)

Cloud Mode
