trajectoriz

Library and CLI to search, browse, and analyze past agent trajectory files. Supports Claude Code, Codex, OpenCode, Copilot, Hermes and more.

Installation

pip install trajectoriz

Search

trajectoriz-cli search lets you find past agent sessions by content — what was discussed, what commands were run, what files were edited.

# AND semantics: all words must appear in a step
trajectoriz-cli search "salary KTH overhead"
trajectoriz-cli search "telegram send_message bot_token"
trajectoriz-cli search "deploy dokku researchers webapp"

# OR semantics: use \| between alternatives
trajectoriz-cli search "pytest\|unittest"

# Restrict to the current project
trajectoriz-cli search "fix login bug" --local

# Fast metadata-only search (first message only, no parsing)
trajectoriz-cli search "refactor auth" --fast

Results are returned as a paginated Markdown table with trajectory ID, agent, date, step number, and a context snippet:

## Search: `salary KTH overhead` — 8 match(es)

| ID           | Agent  | Date       | Step | Snippet                                              |
|---|---|---|---|---|
| `cl-4d72f7b5`| claude | 2026-05-15 | 73   | …kth_salary = ws["E8"].value  # KTH  Direkt lön…   |
| `cl-4ef313e6`| claude | 2026-05-04 | 93   | …Organization: KTH Royal Institute of Technology…  |

Then inspect any result:

trajectoriz-cli show cl-4d72f7b5 --step 73

Search backends

Backend	Setup	Semantics
`grep` (default)	none	substring, in-process
`sqlite`	`trajectoriz-cli refresh --no-recoll`	whole-word FTS5
`recoll`	`trajectoriz-cli refresh --no-sqlite`	full Xapian index

trajectoriz-cli search "openssl handshake" --backend sqlite
trajectoriz-cli search "openssl handshake" --backend recoll

CLI

# List trajectories in the current directory
trajectoriz-cli list

# Show a trajectory (markdown, paginated)
trajectoriz-cli show cl-1234abcd
trajectoriz-cli show cl-1234abcd --last         # jump to the last page
trajectoriz-cli show cl-1234abcd --step 42      # jump to the page containing step 42
trajectoriz-cli show cl-1234abcd --html > out.html   # self-contained HTML export

# Trajectory metadata (JSON)
trajectoriz-cli info cl-1234abcd

# Blame a file — every agent edit in chronological order with line deltas
trajectoriz-cli blame src/main.py

# Aggregate statistics across all trajectories
trajectoriz-cli stats --all

# Aggregate shell-invoked programs across a repo
trajectoriz-cli advanced tools --dir /path/to/repo

Memory filesystem

trajectoriz-cli memory mounts a read-only FUSE filesystem where every local trajectory shows up as an ATIF v1.7 JSON file — so any tool that reads files (grep, an agent's own file tools, etc.) can browse past sessions directly, without going through this CLI.

pip install trajectoriz[fuse]   # requires libfuse (Linux) or macFUSE (macOS)

trajectoriz-cli memory                          # mounts ./memory (created if missing), daemonizes
trajectoriz-cli memory ~/mnt/traj-memory        # or mount elsewhere
trajectoriz-cli memory --foreground             # or run attached

ls memory
cat memory/2026-05-15_claude_cl-4d72f7b5.atif.json

fusermount -u memory                            # unmount (umount on macOS)

Use --dir PATH to expose a different repo's trajectories instead of the current directory's. The listing is recomputed on every access, so new sessions appear without remounting. If the mountpoint sits inside a git repo, it's added to that repo's .gitignore automatically.

Features

Full-content search — three backends (grep / sqlite / recoll); space-separated words are AND, \| is OR; matches at step level across message, tool calls, and results
Unified record API — iterate and parse sessions from Claude Code, Codex, Copilot, OpenCode, Hermes and more through a single iter_records() / parse_record() interface
Blame — trace every agent edit to a file across all trajectory sources, with line/char deltas
HTML export — trajectoriz-cli show <id> --html renders a trajectory as a self-contained HTML page
ATIF export — trajectoriz.atif translates parsed trajectories to ATIF v1.7 (Claude Code, Codex, Copilot, agentknit, or any iter_records()/parse_record() result)
Memory filesystem — trajectoriz-cli memory <mountpoint> mounts a read-only FUSE view where every local trajectory is one ATIF JSON file

Python API

from trajectoriz import iter_records, parse_record

# Iterate sessions across all supported agents (Claude, Codex, Copilot, OpenCode, …)
for record in iter_records():
    print(record.agent, record.timestamp[:10], record.first_msg[:60])

# Iterate sessions for the current project only
for record in iter_records(cwd="/path/to/repo"):
    trajectory = parse_record(record)
    if trajectory is not None:
        print(f"{record.agent}: {len(trajectory.steps)} steps, {trajectory.total_tokens} tokens")
