Telescope

OpenCode TUI plugin for fast keyword search across local conversation history, session transcripts, and past AI coding chats.

Install the npm package @bojackduy/opencode-telescope to grep OpenCode chat history, find old code snippets, scope searches to user asks / assistant replies / thoughts / patches, and jump back to any session instantly.

Inspired by telescope.nvim — a fuzzy finder for your conversation history.

Use cases

• "I know I discussed this somewhere" — grep all your sessions by keyword
• "What did I ask about auth caching?" — scope search to only your prompts with user:auth caching
• "Find that code snippet" — search for code you saw in a past LLM response
• "Find that patch" — scope search to edits and patches with patch:validateForSubmit
• "Revisit a decision" — find the conversation where you chose approach X
• "Session journal" — browse your entire conversation history like a timeline

Features

• Fuzzy grep — fast sidecar FTS search across your prompts and assistant replies
• Scoped queries — opt into noisier fields with thought:, patch:, or tool:name, or narrow with user: and assistant:
• Semantic memory search — optional opt-in local vector search with llama-server embeddings and sqlite-vec
• Live preview — preview the matched conversation result before opening
• Find & jump — select any result and jump straight to that session
• Neovim Telescope-style UX — familiar <leader>f keybind and /telescope command
• Local-first search — reads your OpenCode session database without sending chat history to a remote service

Installation

Install from npm as @bojackduy/opencode-telescope.

Add the plugin to your tui.json:

{
  "plugin": ["@bojackduy/opencode-telescope"],
}

To use it from a local clone:

"plugin": ["./path/to/opencode-telescope"]

Usage

Action	Key / Command
Open search	<leader>f or /telescope
Type to filter	Fuzzy match against conversation text
Navigate results	↑ / ↓ or j / k
Preview	Select a result to see the conversation preview
Open	Press Enter to jump to the selected session
Owner filter	Press o to cycle all / you / assistant

Scoped Search Queries

Telescope defaults to fast keyword search across user prompts and assistant replies only. Thoughts, patches, file names inside patches, and tool output are intentionally excluded from bare search so normal typing stays low-noise. Add a scope prefix when you want those fields:

Query	Searches
user:timeout	Your prompts only
assistant:timeout	Assistant replies only
thought:indexing	Assistant reasoning/thought parts
patch:SearchResponse	Code edits from apply_patch, edit, and write tools
in:patch SEARCH_WORKER_TIMEOUT_MS	Same as patch:..., useful when you prefer in:<scope>
tool:apply_patch SearchResponse	A specific tool's indexed content
timeout patch:SearchResponse	One-line OR search: bare conversation text for timeout or patches for SearchResponse
user:auth patch:SearchResponse	One-line OR search across mutually exclusive scopes
patch:"SearchResponse kind"	Quoted scoped search value with spaces
text:patch:SearchResponse	Literal conversation text that looks like scope syntax
\patch:SearchResponse	Same literal search using a leading backslash escape

Scoped queries highlight only the searched term, so patch:SearchResponse highlights SearchResponse, not the patch: prefix. Multiple one-line clauses use OR, which keeps mixed scopes useful because one indexed row cannot be both user and patch. Explicit scopes override the owner filter.

Semantic Search

Semantic search is optional and opt-in. Keyword and scoped search work out of the box; set OPENCODE_TELESCOPE_ENABLE_VECTOR=1 to enable the local vector path.

The semantic path stays local-first:

• OpenCode's SQLite database is opened read-only.
• Derived keyword and vector indexes are stored in Telescope's sidecar database.
• Keyword updates are incremental: Telescope serves the last-good index while new conversation parts synchronize in small background batches.
• Search and preview workers stay warm across picker openings; keyboard navigation never performs SQLite work directly.
• Embeddings are generated through your local llama-server endpoint.
• If embeddings or sqlite-vec are unavailable, Telescope falls back to keyword search.

Quick setup:

mkdir -p "$HOME/.local/share/opencode-telescope/models"

huggingface-cli download \
  nomic-ai/nomic-embed-text-v1.5-GGUF \
  nomic-embed-text-v1.5.f16.gguf \
  --local-dir "$HOME/.local/share/opencode-telescope/models" \
  --local-dir-use-symlinks false

llama-server \
  -m "$HOME/.local/share/opencode-telescope/models/nomic-embed-text-v1.5.f16.gguf" \
  --embedding \
  --pooling mean \
  -c 8192 \
  -ub 8192 \
  --host 127.0.0.1 \
  --port 8081

Then launch OpenCode with OPENCODE_TELESCOPE_ENABLE_VECTOR=1. Telescope uses http://127.0.0.1:8081 by default and will rebuild the vector sidecar from your local session history.

Useful environment variables:

OPENCODE_TELESCOPE_EMBED_BASE_URL=http://127.0.0.1:8081
OPENCODE_TELESCOPE_EMBED_MODEL=nomic-embed-text-v1.5
OPENCODE_TELESCOPE_HYBRID_ALPHA=0.45
OPENCODE_TELESCOPE_ENABLE_VECTOR=1
OPENCODE_TELESCOPE_DISABLE_VECTOR=1
OPENCODE_TELESCOPE_SQLITE_LIB=/opt/homebrew/opt/sqlite/lib/libsqlite3.dylib
OPENCODE_TELESCOPE_SQLITE_VEC_EXT=/path/to/vec0

See the full tutorial in docs/semantic-search.md.

Configuration

Telescope reads optional plugin-specific config from:

~/.config/opencode/opencode-telescope/config.json

If $XDG_CONFIG_HOME is set, the path is:

$XDG_CONFIG_HOME/opencode/opencode-telescope/config.json

Missing config, invalid JSON, and invalid individual fields are ignored. Defaults are kept for anything not configured.

Example:

{
  "openKey": "<leader>f",
  "keys": {
    "moveDown": ["down", "j"],
    "moveUp": ["up", "k"],
    "scrollPreviewDown": ["d"],
    "scrollPreviewUp": ["u"],
    "open": ["enter", "return"],
    "close": ["q", "escape"],
    "insertMode": ["/"],
    "normalMode": ["ctrl+q"],
    "toggleOwner": ["o"]
  }
}

Key strings support simple names like j, k, down, up, enter, return, and escape, plus modifier strings like ctrl+q.

How it works

Reads the OpenCode local SQLite session database in read-only mode, parses conversations into searchable text, builds a Telescope-owned sidecar index, and opens the selected session through the existing TUI route. Optional semantic search adds local embeddings and sqlite-vec vector retrieval on top of the same sidecar.
