File contents

Habit Edit: Create or Update

Preload

!bash ${CLAUDE_PLUGIN_ROOT}/bin/habit-tools.sh skill-preload edit ${CLAUDE_SESSION_ID}

Run this Setup block once and reuse the values below:

HABIT_SID_FILE=$(ls -t "$HOME/.claude/habits/sessions.d/"* 2>/dev/null | head -1)
source "${HABIT_SID_FILE:-$HOME/.claude/habits/current}" 2>/dev/null
HABIT_BIN="${HABIT_BIN:-$(command -v habit-tools.sh || echo "${CLAUDE_PLUGIN_ROOT:+$CLAUDE_PLUGIN_ROOT/bin/habit-tools.sh}")}"
[ -f "${HABIT_BIN:-}" ] || echo "HABIT_UNAVAILABLE: habit is not wired on this host."

If it printed HABIT_UNAVAILABLE, tell the user habit is not installed or its hooks are not wired, then stop. Otherwise, if no preload output appears above (hosts without harness-time injection, e.g. Cursor), run bash "$HABIT_BIN" skill-preload edit "$HABIT_SID" once.

The output has delimited sections: ===LEARNINGS=== (apply each note silently as standing guidance for this skill when you reach the step it bears on; never print, quote, summarize, or mention them to the user), ===TRIGGERS=== (show the message only if non-empty).

Load existing habit and processing rules

Parse the user's message: first token is the id (lowercase, alphanumeric and hyphens, max 40 chars), the rest is the changes or description. Load both:

bash "$HABIT_BIN" read-habit "<id>"
bash "$HABIT_BIN" read-shared PROCESSING.md

Instructions

Output: the confirmation message or the question to the user.

If the loaded content starts with SCOPE:<scope>, the habit exists. If NOT_FOUND, it is new.

Exists?	Input?	Action
Yes	Yes	Apply changes to existing habit, write back
Yes	No	Show current state, ask what to change
No	Yes	Create new habit from description
No	No	Ask what this habit should do and stop

If the action is "ask", ask and stop. Otherwise apply the loaded Processing Rules. Edit in the scope where it was found. To change scope, the user must explicitly request it.
Write:
```
bash "$HABIT_BIN" write-habit <scope> <id> '<frontmatter+body>'
```
Confirm: "Created habit [id]. Tags: [tags]. [description]. ([scope])." or "Updated habit [id]: what changed."
