Explain a complex topic back to you with visuals - the right diagram for each facet (flowchart, timeline, sequence, schema/ER, state machine, chart, comparison, mind map) plus optional conceptual illustrations - rendered in a style you control, then bundled onto a single page. SELF-CONTAINED: it explains what was already discussed or provided; it does NOT research. Decomposes the topic into the facets that most need to be SEEN, picks a visual modality per facet, renders structural diagrams via themed Mermaid (HTML->PNG, $0) and conceptual facets via /create-explanatory-image, then composes /one-pager to assemble everything into one dense page + PDF. Pick the visual style with --style (brand-dark default, clean-light, blueprint, whiteboard, custom). Use when someone says "explain this to me visually", "show me how this works", "diagram what we just discussed", "make this make sense", or wants a visual brief of a topic.
Generate a brand-locked, information-dense single-page PDF that lets a reader understand an entire topic - a company, a product, a project, a status update, any subject - in one page. Distills a raw brief into a composed grid of reusable blocks (hero-stat, KPI strip, two-column prose, comparison table, timeline, callout, icon-grid, fact-rail, mini-chart), renders one HTML via Playwright to a single PNG, mechanically guarantees it fits on ONE page via a fit-guard + tightening ladder, then wraps it as a 1-page PDF. Default 16:9 landscape; A4/Letter portrait via flag. Dark brand canvas default; light print-friendly theme via flag. Use when someone needs a dense one-pager / one-sheet / fact sheet / briefing doc that ships as a PDF.
Generate a brand-locked multi-slide presentation deck (16:9, 1920x1080) and assemble into a PDF. Mirrors the social-carousel pattern - each slide is an HTML+Playwright PNG render with its own textless soft-futurism hero image. Final step combines all slide PNGs into a single PDF for distribution. Six slide types - cover, section, content, statement, closing on the shared dark canvas brand system, plus a dense type composed via /one-pager for information-dense slides (dashboards, fact sheets, at-a-glance briefings). Use when building a workshop deck, conference talk, internal presentation, or any 16:9 slide set that needs to look brand-coherent and ship as a PDF.

ℹ️ First, set expectations: before anything else, print one short line with this skill's version and its most recent change — the top entry of
metadata.changelogabove — e.g.add-git-sync vX.Y — recent: <summary>. Then proceed.
Installs three hooks that turn the agent's own repo into its durable state layer:
| Hook | Event | Job |
|---|---|---|
git-session-start.sh | SessionStart (startup/resume) | Stash local drift → fetch → rebase onto remote branch → restore drift. Every session begins consistent with origin. |
git-pre-compact.sh | PreCompact | Fast local commit so in-flight work survives context compaction. No push. |
git-sync.sh | Stop (async) | git add -A → commit → push with rebase-on-reject retry. Drops .git/SYNC_FAILED if it can't reconcile; SessionStart surfaces the note next run. |
Who this is for: any agent whose directory is its own git repo and benefits from cross-session continuity (Trinity-deployed agents, autonomous workers, long-running research agents). Not appropriate for agents nested inside a larger monorepo.
Why this pairs with deployment: Trinity deploys an agent by cloning its GitHub repo and tracking the branch, so the remote agent's state is whatever the branch tip holds. These hooks keep that tip honest — work is committed and pushed at session end instead of lingering uncommitted, so a git_pull (or /trinity:sync) actually carries the agent forward. Install this before deploying, not after the first surprise.
Escape hatches baked in:
touch .git/NO_AUTOSYNC — disables all three hooksecho "..." > .git/SELF_SELECT_MSG — subagents write structured commit messages that survive the generic Stop-hook commit.git/SYNC_FAILED — propagates push failures forward to the next sessionRun from inside the target agent directory (or ask the user for the path). Verify:
[ -f CLAUDE.md ] || ask_user_for_agent_path
REPO_ROOT=$(git rev-parse --show-toplevel 2>/dev/null)
[ -z ];
:
[ != ];
1
If no .git/: ask "Initialize git repo here?" If yes, git init.
Use AskUserQuestion with these three questions (in order):
Q1 — Sync mode
remote-push (default) — Stop hook commits and pusheslocal-only — Stop hook commits but does not push (use when there's no remote or the agent is air-gapped)Q2 — Remote and branch (only if Q1 = remote-push)
origin / maingit remote get-url origin fails, ask for the remote URL and set it up before continuingQ3 — Commit co-author line
Co-Authored-By: Claude <noreply@anthropic.com>Templates live in this skill's templates/ directory. Copy to the agent's .claude/hooks/ with placeholder substitution:
SKILL_DIR="$(dirname "$0")" # resolved at runtime
TEMPLATES="$SKILL_DIR/templates"
HOOKS_DIR="$AGENT_DIR/.claude/hooks"
mkdir -p "$HOOKS_DIR"
substitute() {
local src="$1" dst="$2"
sed -e "s|__BRANCH__|$BRANCH|g" \
-e "s|__REMOTE__|$REMOTE|g" \
-e "s|__COAUTHOR__|$COAUTHOR|g" \
"$src" > "$dst"
chmod +x "$dst"
}
if [ "$MODE" = "remote-push" ]; then
substitute "$TEMPLATES/git-session-start.sh" "$HOOKS_DIR/git-session-start.sh"
substitute "$TEMPLATES/git-pre-compact.sh" "$HOOKS_DIR/git-pre-compact.sh"
substitute "$TEMPLATES/git-sync.sh" "$HOOKS_DIR/git-sync.sh"
else
# local-only: no SessionStart (no remote to rebase from)
substitute "$TEMPLATES/git-pre-compact.sh" "$HOOKS_DIR/git-pre-compact.sh"
substitute "$TEMPLATES/git-sync-local.sh" "$HOOKS_DIR/git-sync.sh"
fi
Idempotency: before overwriting any existing hook file, diff content. If identical, skip silently. If different, show the diff and ask the user whether to overwrite.
.claude/settings.jsonLoad existing settings (create {} if missing), merge the hooks block, write back. Use jq to keep the JSON canonical:
SETTINGS="$AGENT_DIR/.claude/settings.json"
[ -f "$SETTINGS" ] || echo '{}' > "$SETTINGS"
# Build the hooks JSON we want to ensure is present
NEW_HOOKS=$(jq -n --arg mode "$MODE" '{
SessionStart: (if $mode == "remote-push" then [{
matcher: "startup|resume",
hooks: [{
type: "command",
command: "\"$CLAUDE_PROJECT_DIR\"/.claude/hooks/git-session-start.sh",
timeout: 20,
statusMessage: "Syncing from git..."
}]
}] else null end),
PreCompact: [{
hooks: [{
type: "command",
command: "\"$CLAUDE_PROJECT_DIR\"/.claude/hooks/git-pre-compact.sh",
timeout: 15,
statusMessage: "Snapshotting pre-compact..."
}]
}],
Stop: [{
hooks: [{
type: "command",
command: "\"$CLAUDE_PROJECT_DIR\"/.claude/hooks/git-sync.sh",
timeout: 45,
statusMessage: "Syncing to git...",
async: true
}]
}]
} | with_entries(select(.value != null))')
# Merge: existing + new (new entries fill gaps; do NOT overwrite existing hook arrays
# for the same event — append instead, and warn the user if there are duplicates).
jq --argjson new "$NEW_HOOKS" '
.hooks = (
(.hooks // {}) as $existing
| $new as $toAdd
| reduce ($toAdd | keys_unsorted[]) as $event ($existing;
.[$event] = (( .[$event] // [] ) + $toAdd[$event])
)
)
' "$SETTINGS" > "$SETTINGS.tmp" && mv "$SETTINGS.tmp" "$SETTINGS"
Idempotency check: before merging, scan existing hooks.<event> arrays for any entry whose command already points at .claude/hooks/git-*.sh. If found, skip that event and print [already installed].
.gitignoreAdd only entries not already present. Block-wrap with a header so it's clear what added them:
# --- agent-dev:add-git-sync runtime exclusions ---
# Trinity (#2036) ignores .claude/settings.json fleet-wide and `git rm --cached`s
# an already-committed copy on the next Push, because the base image bakes its own
# container-only copy and HOME is the repo root. THIS SKILL registers its hooks in
# that file — so on a Trinity-deployed agent the registration would be untracked and
# the whole setup would silently stop existing. Emit BOTH lines, plain rule FIRST:
# the plain line satisfies Trinity's exact-line `grep -qxF` gate so it stops appending
# its own copy at the end of the file, and the negation comes last so git's
# last-match-wins re-includes the file.

Before appending, grep each line against the existing .gitignore and skip duplicates. If the entire block header is already present, skip the section entirely.
CLAUDE.mdCheck if a ## Git Sync or **[GIT SYNC (AUTOMATIC)]** section already exists. If yes, skip. If no, append:

## Git Sync (Automatic)
Three hooks manage git sync for this agent. Defined in `.claude/settings.json`, scripts in `.claude/hooks/`.
| Hook | Script | Purpose |
|---|---|---|
| `SessionStart` | `git-session-start.sh` | Auto-stash drift, fetch + rebase onto `<REMOTE>/<BRANCH>`, restore drift. |
| `PreCompact` | `git-pre-compact.sh` | Snapshot commit before compaction so mid-flight work survives context loss. No push. |
| `Stop` (async) | `git-sync.sh` | Commit staged files, push with rebase-on-reject retry (max 2). Honors `.git/SELF_SELECT_MSG` for structured commit messages. |
**Escape hatches:**
- `touch .git/NO_AUTOSYNC` — disable all three hooks until removed
- `echo "msg" > .git/SELF_SELECT_MSG` — override Stop-hook commit message (consumed after use)
- `.git/SYNC_FAILED` — written when push can't reconcile; surfaced in next SessionStart
**Design principle:** hooks enforce session-boundary consistency. Inside a session the agent is free; at boundaries (start / compact / stop) the repo reconciles.
Substitute <REMOTE> and <BRANCH> (or drop the SessionStart row entirely in local-only mode).
Before declaring success, run:
# Syntax check each hook
for h in "$HOOKS_DIR"/git-*.sh; do
bash -n "$h" || { echo "SYNTAX ERROR in $h"; exit 1; }
done
# settings.json parses
jq empty "$SETTINGS" || { echo "settings.json is invalid JSON"; exit 1; }
# .gitignore parses (just ensure it's readable)
[ -r "$AGENT_DIR/.gitignore" ]
Print a summary of what was added and what was skipped (idempotent no-ops).
## Git Sync Installed
Mode: **<MODE>** (remote-push / local-only)
Remote: `<REMOTE>/<BRANCH>` (if applicable)
### What's active
- SessionStart: auto-rebase onto remote
- PreCompact: safety snapshot
- Stop: auto-commit (and push, if remote-push)
### First-run checklist
1. Commit this setup: `git add .claude/hooks/ .claude/settings.json .gitignore CLAUDE.md && git commit -m "Add git-sync hooks"` — then verify the negation actually wins with `git check-ignore -v .claude/settings.json` (it should report the `!` line, or report nothing). If `settings.json` is ignored, the hooks are registered nowhere on any clone but this one.
2. If remote-push: confirm `git remote -v` points at the right repo
3. Trigger a test: make a trivial edit, let the session end, verify a Heartbeat commit appears
### Disable temporarily
`touch .git/NO_AUTOSYNC` — re-enable by deleting the file.
jq must be installed (it's used by every hook and by this skill's settings merge). Check with command -v jq in Step 1; bail with install instructions if missing.local-only mode at their own risk (the Stop hook would still commit to the wrong scope — safer to refuse).__COAUTHOR__ placeholder is substituted as a single line. If the user wants multi-line sign-offs, they can edit git-sync.sh directly post-install.
