Note

/note — status-line reminder (per session)

Pin a short reminder for the user to the Claude Code status line. A status-line snippet reads the note for the current session from $CFG/notes/<session_id>.txt and renders it on its own line with a bold black-on-yellow "sticky note" background. The note is scoped to its session (it does NOT leak into other Claude sessions) and persists until cleared.

Throughout, CFG means ${CLAUDE_CONFIG_DIR:-$HOME/.claude} — the agent's config dir. The current session id is in the env var $CLAUDE_CODE_SESSION_ID (use it verbatim; never hardcode).

First-time setup (run once per machine)

Before setting the first note, make sure the status line is wired to render it. This is idempotent — safe to run every time; it no-ops if already installed:

bash ~/.claude/skills/note/scripts/install-note-statusline.sh

(Use wherever this skill is installed.) The installer injects a guarded snippet into CFG/statusline-command.sh. If no status line exists yet it creates one and prints the line to add to settings.json ("statusLine": { "type": "command", "command": "bash <path>" }); relay that to the user. If you see "already installed", stay silent about setup and just set the note.

Behavior

Look at the argument the user passed after /note (or the equivalent natural-language request).

1. Clearing a note

If the argument is empty, or is one of: clear, done, remove, delete, off, x → remove this session's note file and confirm:

rm -f "${CLAUDE_CONFIG_DIR:-$HOME/.claude}/notes/$CLAUDE_CODE_SESSION_ID.txt"

Then reply in one line: Note cleared.

2. Setting / replacing a note

Otherwise, synthesize the user's input into a single terse reminder line:

• Strip filler ("remind me to", "note to self", "don't forget") — keep only the actionable gist.
• Imperative, present tense. No trailing punctuation.
• Keep it short — aim for ≤ 45 characters so it fits the status line. If the source is long, compress to the essential cue, not a full sentence.
• Single line only — strip any newlines.

Write the synthesized text (no quotes, no markdown, no emoji — the status line adds its own 📌) to this session's file:

cfg="${CLAUDE_CONFIG_DIR:-$HOME/.claude}"; mkdir -p "$cfg/notes"
printf '%s' 'SYNTHESIZED_NOTE_HERE' > "$cfg/notes/$CLAUDE_CODE_SESSION_ID.txt"

Use printf '%s' (not echo) so no trailing newline is added. Single-quote the note; if it contains a literal single quote, escape it as '\''.

Then reply in one line showing exactly what was pinned, e.g.: Pinned: ship the eval on the Mac Studio

Notes

• The note is per-session — one active note per Claude session; setting a new one replaces this session's.
• It persists across compactions/restarts of the same session until cleared.
• The status line refreshes on activity, so a freshly pinned note appears on the next render (the next message/tool action), not instantly.
• Old sessions' note files harmlessly remain in CFG/notes/; the status line only shows the current session's.
• Do not over-explain; this is a fast utility. One-line confirmation only.
