nplog

A tool that reads NotePlan’s structured plugin log to investigate what happened during a plugin action. NotePlan is a notes and planning app, and its plugin log records plugin activity and errors.

In plain words
What is it for?
Use it to inspect recent plugin runs, follow activity after an x-callback command, wait for delayed log entries, and return structured records for debugging.
Why use it?
It shows delayed or asynchronous plugin activity without relying on guesses or manually reading the raw log. It is useful when a command does nothing, throws an error, or behaves unexpectedly.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

nplog scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Reading the NotePlan plugin log

scripts/nplog/nplog (in this repo) parses NotePlan's log into structured records. Run it as node scripts/nplog/nplog from the repo root, or just nplog if scripts/nplog/install.sh has been run.

Always use --json for programmatic reading. The default mode is a full-screen interactive viewer for humans and will hang a non-TTY caller.

The core loop: "what happened when I did X?"

CURSOR=$(node scripts/nplog/nplog --mark)
open "noteplan://x-callback-url/runPlugin?pluginID=jgclark.Dashboard&command=Show%20Dashboard"
node scripts/nplog/nplog --since "$CURSOR" --follow --wait-idle 5 --json

An x-callback returns immediately while the plugin keeps running — a Dashboard refresh ping-pongs asynchronously for anywhere from 2 to 30 seconds. Do not guess a duration:

  • --follow streams entries as they arrive.
  • --wait-idle 5 stops after five seconds of silence. A run still in flight writes something within five seconds, so that much quiet means it finished.
  • --timeout (default 90s) is the hard cap.

The log flushes in batches. Measured: the file sat untouched for 24s after an action, then gained 80 lines at once. So never conclude "the action logged nothing" from an empty result — check the summary's sawOutput and timedOut fields, which exist precisely to tell that apart from "I looked too early". Do not lower --timeout below ~30s.

Exit code 1 means at least one emitted entry was an ERROR — check it before reading anything, it is the cheapest possible signal.

Recipes

# only the most recent plugin invocation
node scripts/nplog/nplog --json --last-run

# the last 10 minutes (also accepts 30s / 2h / a bare number = minutes,
# or a local wall-clock time like 19:36 or "2026-07-29 19:36")
node scripts/nplog/nplog --since 10m --json

# problems only
node scripts/nplog/nplog --since 10m --json --min-level warn

# find a diagnostic line and see the 10 entries that followed it
node scripts/nplog/nplog --json --mode 10 '\[DIAG\]'

# keep the output small (default 500; truncation is always reported, never silent)
node scripts/nplog/nplog --since 1h --json --max-entries 50

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

nplog is a skill published in the GitHub repository NotePlan/plugins (204 stars, last pushed 3d ago), licensed MIT. It adds 109 tokens to every session and 1,538 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
