Vault re-sync

This pulls the user's scattered capture sources into one place — the Obsidian vault inbox — and refreshes the dashboards they read. The whole point of the vault system is that they shouldn't have to hold "what's new across Feishu / WeChat / ~1500 browser tabs / my Claude projects" in their head. This skill is the recurring sweep that keeps that promise.

User-specific values (vault path, Feishu app details, the WeChat self-chat hint) live in local.private.md next to this SKILL.md — it's gitignored and machine-local, kept out of the public repo on purpose. Read it at the start of a run. Where a value can be discovered at runtime instead of stored, prefer that (noted per-source below). $VAULT below = the vault root from the sidecar.

The four sources → where they land

Source	Tool	Output note
Feishu tasks + all-chat messages	lark-cli (read-only scopes)	01_inbox/feishu/feishu-inbox-<date>.md + feishu-messages-<date>.md
WeChat self-saves	chatlog HTTP API	01_inbox/wechat/wechat-inbox-<date>.md
Zen browser tabs	scripts/decode_zen_tabs.py	01_inbox/tabs/zen-tabs-<date>.md
Active Claude sessions	list_sessions MCP	01_inbox/projects/claude-projects.md (the AI Build Queue)

<date> is today as YYYY-MM-DD. Always read the previous dated note first so you can frame the pull as "what's new since last sync" rather than re-dumping everything.

Orchestration pattern (do it in this order)

1. Snapshot first. cd "$VAULT" && git add -A && git commit -m "snapshot before re-sync". This gives a restore point before you write anything.
2. Pre-flight: disk space. See "Disk pre-flight" — a full disk silently breaks everything, including your own shell. Check before you start.
3. Fan out the slow pulls. Feishu and WeChat each involve many API calls and per-conversation summarization — launch them as parallel background subagents (one per source) using the prompts in references/sources.md, so they run while you do the fast local work.
4. Do the fast local pulls inline while the agents run: decode Zen tabs (one script call) and rebuild the AI Build Queue from list_sessions.
5. Fold in the agent results as they land. Read each agent's summary; don't re-read the full note unless something looks off.
6. Update the Command Center. Repoint the capture-source links in homepage.md to the new dated notes, and surface any genuinely actionable finding (a deadline, an escalation) onto Tasks Board.md with an area tag + due date — don't let a real action item rot inside a digest.
7. Commit + push. git add -A && git commit -m "Re-sync all capture sources (<date>): ..." && git push. If push fails with an HTTP/2 framing error, retry with git -c http.version=HTTP/1.1 push.

Scale to what was asked. "Re-sync everything" → all four. "What's new in Feishu" → just that one, still following its source rules.

Disk pre-flight

A 100%-full disk on macOS makes the shell itself fail (ENOSPC: no space left on device) — commands can't even write their output, so you'll be blocked before you start. If a trivial Bash call errors with ENOSPC, the disk is the problem, not your command.

The user has Burrow for exactly this — its MCP tools run out-of-process so they work even when the shell can't. Use burrow_doctor (read-only health) and burrow_analyze (size-ranked tree) to see the situation, and burrow_clean to clear caches. Caches rarely free enough alone; the big wins are usually VM images, app DB backups (e.g. ~/Library/Application Support/Dayflow/backups + timestamped Dayflow.backup-* copies), and stale build dirs. Only auto-delete caches. For real user data — VMs, project folders, app data — show the user the sizes and let them choose. Never nuke a directory you didn't create without their say-so.

Per-source details

Each source has non-obvious auth/format traps. Read references/sources.md before pulling — it has the exact commands, the subagent prompts, and the gotchas. The traps that bite hardest:

• Feishu — read-only scopes ONLY. Re-auth (only if needed) with lark-cli auth login --scope task:task:read,im:message:readonly,im:chat:read,contact:user.base:readonly. Never use --domain — that requests write scopes, and authorizing write scopes triggers a slow enterprise admin review that has cost hours. A needs_refresh token auto-refreshes on the first valid API call; only if that fails do you re-auth (you can drive the logged-in browser to click Authorize). App/enterprise IDs and the dev-console URL are in local.private.md.
• WeChat — discover the self-chat at runtime. It's the chat flagged isSelf in the chatlog session list, NOT filehelper / 文件传输助手 (which is empty). The chatlog server must be running (chatlog server, binary at ~/go/bin/chatlog) on http://127.0.0.1:5030. Quote URLs in curl — a bare ? gets eaten by zsh globbing and looks like a dead server when it isn't.
• Zen tabs — use the bundled script. python3 scripts/decode_zen_tabs.py --out "$VAULT/01_inbox/tabs/zen-tabs-<date>.md" --date <date>. It handles the mozlz4 decode with no dependencies. Don't pip install lz4 (PEP 668 blocks it).
• Claude sessions — dedupe by folder, flag status. list_sessions returns ~85 with heavy duplication (recurring "weekly sync" etc.) and many merged-PR sessions that are actually done. Group by cwd, collapse dupes, flag ✅-done (merged PRs) as archive candidates, surface what's new since last sync.

Quality bars (what makes this "the same high quality")

• Dedupe and categorize, don't dump. 1,500 raw URLs or 250 raw messages is just moving the mess. Bucket, summarize, count. The note should be skimmable in 30 seconds.
• Surface deadlines as tasks. A real commitment with a clock (a demo date, an escalating reminder) belongs on the board with a 📅 due date, not buried in prose.
• Frame as a delta. "9 new since 06-23" beats re-listing 259 old items. Read the prior note first.
• Keep Chinese text as-is but make it scannable.
• Don't loop on Feishu auth. If read-only re-auth still fails, stop and tell the user — repeated login attempts re-trigger the admin-review trap. One clean attempt, then escalate.

After a re-sync, give a tight recap: what each source surfaced, the count of new items, and the one or two things that actually need attention this week.
