prune-discussions

Prune old discussions from `~/.things/for-the-record/discussions/`. Three modes: use the configured `discussion_retention_days` preference (default), specify `--older-than ` explicitly, or use `--interactive` to pick specific files. Always confirms before deleting. Load Configuration

<load-config>
  <action>Resolve the user's home directory.</action>
  <command language="bash" output="home" tool="Bash">echo $HOME</command>
  <constraint>Never pass `~` to the Read tool.</constraint>

  <read path="<home>/.things/config.json" output="config" />
  <if condition="config-missing">Tell the user: "Run `/things:setup-things` first." Then stop.<exit /></if>

  <read path="<home>/.things/for-the-record/preferences.json" output="preferences" />
  <if condition="preferences-missing">Tell the user: "Run `/setup-ftr` first." Then stop.<exit /></if>
</load-config>

Determine Pruning Mode

<action>Parse `$ARGUMENTS` for:</action>
- **--older-than <days>**: Delete discussions older than N days
- **--interactive**: Show all discussions for manual selection

<if condition="--interactive">
  <action>Use interactive mode (step 4).</action>
</if>

<if condition="--older-than provided">
  <action>Use the explicit days value.</action>
</if>

<if condition="no flags">
  <action>Use `preferences.discussion_retention_days`.</action>
  <if condition="discussion_retention_days is null or missing">
    <action>Tell the user: "No retention policy configured and no `--older-than` flag provided. Either run `/setup-ftr reconfigure` to set `discussion_retention_days`, or use `--older-than <days>` or `--interactive`." Then stop.</action>
    <exit />
  </if>
</if>

Find Deletion Candidates (age-based)

<if condition="age-based mode">
  <action>List all `.md` files in `<home>/.things/for-the-record/discussions/`. Parse the date from each filename (YYYY-MM-DD prefix) or from frontmatter. Calculate age in days from today.</action>

  <action>Filter to files older than the threshold.</action>

  <if condition="no candidates">
    <action>Tell the user: "No discussions older than <N> days found." Then stop.</action>
    <exit />
  </if>

  <output>
  Discussions older than <N> days:

    1. <filename> (<date>, <age> days old)
    2. <filename> (<date>, <age> days old)
    ...

  Total: <count> files to delete
  </output>

  <ask-user-question>
    <question>Delete these <count> discussions?</question>
    <option label="Yes">Delete all listed discussions</option>
    <option label="No">Cancel -- keep everything</option>
  </ask-user-question>
</if>

Interactive Selection

<if condition="interactive mode">
  <action>List all `.md` files in `<home>/.things/for-the-record/discussions/` with date and title from frontmatter.</action>

  <if condition="no discussions">
    <action>Tell the user: "No discussions found." Then stop.</action>
    <exit />
  </if>

  <output>
  Discussions:

    1. <filename> -- "<title>" (<date>)
    2. <filename> -- "<title>" (<date>)
    ...
  </output>

  <ask-user-question>
    <question>Which discussions would you like to delete? Enter numbers (e.g., "1,3"), a range (e.g., "1-5"), or "all".</question>
  </ask-user-question>

  <ask-user-question>
    <question>Confirm: delete <count> selected discussions?</question>
    <option label="Yes">Delete selected discussions</option>
    <option label="No">Cancel</option>
  </ask-user-question>
</if>

Delete Files

<command language="bash" tool="Bash">rm "<home>/.things/for-the-record/discussions/<filename>"</command>

Trigger Rebuild

<action>Read `<home>/.things/registry.json` to find the rebuild command for `for-the-record/discussions`. Execute it.</action>
<constraint>If the rebuild command is not found, fall back to: `python3 <cached-path>/scripts/rebuild-index.py <home>/.things`</constraint>

Handle Git Workflow

<git-workflow>
  <action>Pull latest before committing.</action>
  <command language="bash" tool="Bash">git -C <home>/.things pull --rebase 2>/dev/null || true</command>

  <action>Read git workflow from `config.json` (`git.workflow`).</action>

  <if condition="workflow-auto">Automatically `git add`, `git commit -m "prune: <count> discussions"`, and `git push`.</if>
  <if condition="workflow-ask">
    <ask-user-question>
      <question>Commit and push the pruned discussions?</question>
      <option>Yes -- commit and push</option>
      <option>Commit only</option>
      <option>No -- I'll handle git myself</option>
    </ask-user-question>

  <if condition="workflow-manual">Tell the user the pruning is complete.</if>
