share-code

Draft platform-aware social media copy and generate a styled dark-mode card image for any supported platform (see $PLUGIN_DIR/references/platforms.md).

Quick Reference

Phase	Action
0 — Locate	Locate templates/ and derive PLUGIN_DIR
1 — Clarify	Auto-detect from git; ask platform + tone
1c — Reuse check	Scan docs/media/social/ for existing posts; offer reuse
2 — Draft	Write platform-aware copy
3 — Pick template	diff → diff-card, feature → feature-card, insight → quote-card
4 — Populate	Read template, substitute {{VARIABLES}} including {{COPY_PANELS}}
4b — Save	Persistent save to docs/media/social/
5 — Screenshot	Serve HTML locally, Playwright screenshot
6 — Deliver	Present copy + attach PNG + show saved path

Exit plan mode

ExitPlanMode is a deferred tool. Only call it if currently in plan mode — skip this step entirely when not in plan mode. When calling: use ToolSearch with select:ExitPlanMode first, then call ExitPlanMode silently.

Phase 0 — Locate Plugin Assets

Run silently:

[ -n "${CLAUDE_PLUGIN_ROOT}" ] && [ -d "${CLAUDE_PLUGIN_ROOT}/templates" ] && \
  echo "${CLAUDE_PLUGIN_ROOT}/templates"
find ~/.claude/plugins -path "*/social-media-tools/templates" -type d 2>/dev/null | head -1
find ~/.claude -path "*/social-media-tools/templates" -type d 2>/dev/null | head -1

Use the first non-empty result as TEMPLATES_DIR. Derive:

PLUGIN_DIR=$(dirname "$TEMPLATES_DIR")

If no directory is found: output "Templates not found. Install the plugin or load it with --plugin-dir." and STOP.

---

Phase 0b — Load Project Sharing Config

Check for SOCIAL.md (see $PLUGIN_DIR/references/social-config.md):

SOCIAL_CONFIG=""
GIT_ROOT="$(git rev-parse --show-toplevel 2>/dev/null)"
if [ -f "$PWD/SOCIAL.md" ]; then
  SOCIAL_CONFIG="$PWD/SOCIAL.md"
elif [ -n "$GIT_ROOT" ] && [ -f "$GIT_ROOT/SOCIAL.md" ]; then
  SOCIAL_CONFIG="$GIT_ROOT/SOCIAL.md"
fi

If found, Read it silently. Extract DEFAULT_PLATFORM, DEFAULT_TONE, DEFAULT_HASHTAGS, FOCUS_AREAS, and AUDIENCE from the parsed sections. These serve as defaults — user input in $ARGUMENTS always overrides them.

---

Phase 1 — Clarify

Run silently:

git diff HEAD~1 --stat 2>/dev/null | head -20
git log --oneline -5 2>/dev/null
head -30 CHANGELOG.md 2>/dev/null

• Non-empty diff stat → auto-select diff-card
• Commit with feat: prefix or version bump → auto-select feature-card
• Context found: summarise in one sentence, ask only platform and tone (pre-select DEFAULT_PLATFORM and DEFAULT_TONE from SOCIAL.md if available)
• No context: ask all three inputs via AskUserQuestion
• When FOCUS_AREAS are set, use them to pick the most relevant commit or change as the card's angle
• When AUDIENCE is set, use it to calibrate vocabulary and detail level
• When DEFAULT_HASHTAGS are set, append them per platform rules in Phase 2

---

Phase 1c — Reuse Check

FILE_PREFIX=<detected-card-type>   # diff, feature, or quote

Read $PLUGIN_DIR/references/reuse-check.md and follow its procedure.

---

Phase 2 — Draft Copy

Read $PLUGIN_DIR/references/platforms.md for character limits, tone defaults, the Instructional Voice doctrine, Learn-More CTA rule, Default Per-Platform Copy Formats, and Draft Copy — Standard Procedure (present → approve → store variants).

Takeaway-first: every post must surface a concrete, applicable takeaway — what the reader can learn or apply from this code change (a pattern, technique, pitfall avoided, or design principle). The diff or feature is evidence for the lesson, not the headline.

---

Phase 3 — Pick Template

• diff-card.html — code changes, rule updates, config diffs, PR descriptions
• feature-card.html — releases, new features, version announcements, changelogs
• quote-card.html — insights, opinions, pull quotes, teachable principles

CARD_TYPE=<chosen>          # diff, feature, or quote
TEMPLATE_FILE=$TEMPLATES_DIR/${CARD_TYPE}-card.html
TEMP_HTML=code-share-card.html
FILE_PREFIX=$CARD_TYPE
SLUG_INPUT=<commit subject, filename, or feature title>

---

Phase 4 — Populate Template

Read TEMPLATE_FILE. For variable reference, read $PLUGIN_DIR/references/variables.md.

For {{COPY_PANELS}} markup and escaping rules, read $PLUGIN_DIR/references/copy-panels.md.

Write the populated HTML to ~/.claude/tmp/code-share-card.html:

mkdir -p ~/.claude/tmp

---

Phase 4b — Persistent Save

Variables set in Phase 3: FILE_PREFIX, SLUG_INPUT, TEMP_HTML.

Read $PLUGIN_DIR/references/saving-and-delivery.md — Persistent Save section.

---

Phase 5 — Screenshot

Read $PLUGIN_DIR/references/rendering-pipeline.md and follow the full pipeline.

---

Phase 6 — Deliver

Read $PLUGIN_DIR/references/saving-and-delivery.md — Deliver section.
