InstruktAI Python Logger

Centralized logging utilities for Python services.

This repo provides a shared, consistent logging contract (env vars + output format + log location) intended to keep logs highly queryable (including by AIs that only read a tail window).

Background and rationale live in docs/design.md. Publishing notes live in docs/publishing.md.

Install (editable, local workspace)

From PyPI (recommended):

pip install instruktai-python-logger

From GitHub:

pip install git+ssh://[e-mail]/InstruktAI/python-logger.git

API

• Python entrypoint: instrukt_ai_logging.configure_logging(...)
• Logger helper: instrukt_ai_logging.get_logger(name) (named **kv logging)
• CLI entrypoint: instrukt-ai-logs (reads recent log lines)

Example:

import logging
from instrukt_ai_logging import configure_logging

configure_logging("teleclaude")
logger = logging.getLogger("teleclaude.core")
logger.info("job_started", job_id="abc123", user_id=123)

Per-process log files (multi-producer apps)

When several processes belong to the same app (a daemon plus a watcher plus a cron, for example), each one can own its own file under the same app directory by passing source=:

configure_logging("teleclaude")                       # → teleclaude.log (default)
configure_logging("teleclaude", source="docs-watch")  # → docs-watch.log
configure_logging("teleclaude", source="cron")        # → cron.log

The .log extension is always appended; pass the bare stem. Files all live under $XDG_STATE_HOME/instrukt-ai/{app}/ (fallback ~/.local/state). The CLI merges them transparently (see below).

Environment variables (contract)

Per-app prefix model (example uses TELECLAUDE_):

• TELECLAUDE_LOG_LEVEL
• TELECLAUDE_THIRD_PARTY_LOG_LEVEL
• TELECLAUDE_THIRD_PARTY_LOGGERS (comma-separated logger prefixes to spotlight, e.g. httpcore,telegram)
• TELECLAUDE_MUTED_LOGGERS (comma-separated logger prefixes to force to WARNING+, e.g. teleclaude.cli.tui)

These four per-app variables are the entire contract. There is no log-root override variable — the location is a fixed rule (see below).

Log location (contract)

Every app's logs live at the same predictable, prose-citable location on both macOS and Linux:

• $XDG_STATE_HOME/instrukt-ai/{app}/{app}.log (fallback ~/.local/state, per the XDG Base Directory spec)

This path is always user-writable — no installer step, no sudo, no elevated permissions. configure_logging(...) raises immediately if the log file cannot be opened; logging is an essential subsystem and a process that cannot write its logs must not start blind.

Rotation

Rotation is transparent and runs entirely in user space: configure_logging(...) idempotently ensures a per-user rotation conf plus a per-user scheduler (a launchd LaunchAgent on macOS running newsyslog, a systemd user timer on Linux running logrotate) on every process start. No /etc configuration, no sudo, and no system rotation daemon ever touches these files, so rotated/recreated logs always stay owned by the producing user. Run instrukt-ai-log-setup to check rotation-asset status manually; normal operation never requires it.

CLI

# Last 10 minutes (default), follows
instrukt-ai-logs teleclaude -f

# Last 2 hours
instrukt-ai-logs teleclaude --since 2h

# Filter with regex
instrukt-ai-logs teleclaude --since 10m --grep 'logger=teleclaude'

# Follow (tail -f style) after printing the --since window
instrukt-ai-logs teleclaude --since 10m --follow

# Restrict to specific source streams (per-process files)
instrukt-ai-logs teleclaude --since 1h --logs=cron,docs-watch

Without --logs, every *.log* file in the app directory is merged by timestamp (rotation suffixes included). With --logs=stem1,stem2, only files whose stem matches an entry are read — exact stem match, so --logs=cron picks cron.log, cron.log.0, cron.log.1 and never cron-backup.log. Follow mode reads each selected file with one polling thread per file.
