Past Claude Code, Codex, GitHub Copilot, DeepSeek Harness, Hermes Agent, Kiro, Kimi Code, OMP, Pi, and ZCode sessions -- queryable by your agent, browsable by you.

English · 中文

Obelisk indexes your local coding-agent history into one SQLite database and serves it to two audiences:

• Agents — the obelisk CLI plus an agent skill that teaches coding agents to search their own session history. The agent writes JS queries, runs them locally, and answers in plain language.
• Humans — an Electron desktop app to browse sessions, manage memories, view usage stats, and see weekly recap cards.

Both read the same ~/.obelisk/obelisk.sqlite, kept fresh by watching every configured provider directory.

20K lines of scattered JSONL → something your agent can search() and sql() against in milliseconds.

The shortest path is to give the bootstrap guide directly to a coding agent with shell access. Paste this as a prompt into Claude Code, Codex, or another agent — not into your terminal:

Install Obelisk by fetching and following this guide:
curl -fsSL https://raw.githubusercontent.com/tommy0103/obelisk/main/SKILL.md

The agent will ask before changing your machine, install and verify the CLI, then ask whether the formal /obelisk skill should be installed for the current project or globally. The bootstrap guide is only for one-time setup; it is not the query skill itself.

Obelisk requires Node.js 22.13 or newer. Install the platform-neutral CLI (zero runtime npm dependencies — it uses Node's built-in SQLite):

npm install --global @obelisk-apps/cli
obelisk --version

On macOS, Linux, or WSL, the CLI-only installer is equivalent:

curl -fsSL https://raw.githubusercontent.com/tommy0103/obelisk/main/install.sh | sh

Then install the agent skill:

obelisk install

obelisk install delegates to the standard skills installer for tommy0103/obelisk-skill. Then in any agent session: /obelisk <your question>. First run builds the index (~5 seconds for 100 sessions); after that it rebuilds incrementally.

You ask a question
  ↓
Agent writes a JS query against the SQLite index
  ↓
Runs it via obelisk --query <script>
  ↓
Reads the JSON result, answers in natural language

Default query surface (CLI 0.3.0+): overview(), sessions(), search(), messages(), memories(), summaries(), and sql(). Specialized helpers and legacy script globals remain available. Signatures, options, and query patterns live in the API reference.

When a retrieval produces a conclusion worth keeping, the agent proposes a markdown memory file. After your approval, it registers the file with obelisk --attune <script>. Memories are recalled via memories() in future sessions — a synthesis cache, not a replacement for raw evidence.

The optional /obelisk recap flow turns a period of sessions into shareable weekly/monthly recap cards. It loads its references only for explicit recap intent, starting at skill-doc/references/recap/overview.md and proceeding card by card.

• Sessions — browse all sessions with search, project filtering, readable tool calls (diffs, terminal output, file viewers)
• Memory — list and detail views for registered memory files
• Activity — GitHub-style heatmap, weekly/cumulative token charts
• Recap — shareable weekly/monthly recap cards with archetype theming
• Settings — data source configuration, auto-refresh, rebuild index

Prebuilt releases are available for macOS and Linux amd64 from Releases, with in-app updates (Sparkle on macOS, DebUpdater on Debian installations). On macOS, Windows, and Linux you can also run the app from source — Node.js 22.13+ for the build tools; the app itself runs on Electron's embedded Node:

git clone https://github.com/tommy0103/obelisk.git
cd obelisk/app
npm ci
npm run dev

Debugging, packaging, and the release workflow are maintainer docs; they live in CONTRIBUTING.md.

Note: while the desktop app is running it owns index writes, so CLI invocations stay read-only.

Every provider projects into the same shared layers; a few layers exist only where the source tool has the concept:

Full-text search via FTS5 covers all layers. Per-provider source locations are listed under Provider coverage.

Every provider indexes into the same schema; rows carry a source value and non-Claude IDs are provider-prefixed so they cannot collide.

Where a provider attests superseded history, Obelisk preserves it as inactive rows that normal queries omit; supported query helpers can opt in with includeInactive: true.

Non-default locations — a Pi --session-dir, an OMP custom root, the VS Code Insiders User directory — can be selected in the app's Settings.

Adapter internals (identity hashing, supersession replay, per-provider root discovery) are documented in retrieval semantics and the ADRs.

Contributions are welcome. Read CONTRIBUTING.md before opening a PR — it is short, and it is written from what actually blocked past PRs rather than from generic style rules. The parts worth knowing up front:

• Run every claim in your PR description end to end. The most common reason a PR stalls here is a capability that is advertised but unreachable — including inputs shown in screenshots.
• Assert the requirement, not the implementation. Copy the sentence from the issue into your test name.
• Transcript content is attacker-controlled. Obelisk indexes third-party agent logs; anything reaching shell.*, fs.*, innerHTML, or DDL is deny-by-default.
• Re-run verification after merging main. A merge voids every result above it, including your own noted limitations.
