Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00060 | $0.01410 |
| Opus 5 | $0.00030 | $0.00705 |
| Sonnet 5 | $0.00012 | $0.00282 |
| Haiku 4.5 | $0.00006 | $0.00141 |
Grade A, and why
inbox-catchup scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 176 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Inbox Catchup
Scan connected communication sources, build a prioritized briefing, and help triage and respond.
Configuration
Edit these defaults before uploading, or override at runtime when prompted.
sources: all # "all" or comma-separated: gmail, calendar, slack
time_window: 4h # How far back to scan: 1h, 4h, today, yesterday
priority_contacts: [] # Names/emails that always surface first
reply_tone: professional # professional, casual, brief
auto_draft: true # Offer to draft replies for items that need response
Process
1. Detect Available Sources
Check what communication integrations and tools are accessible in this session:
- Google Workspace — Gmail (unread/recent emails), Google Calendar (upcoming events)
- MCP servers — Check for any connected messaging tools (Slack, Teams, Discord, etc.)
- Other integrations — Any other data sources available
Report what was found:
Connected sources:
✅ Gmail — via Google Workspace
✅ Google Calendar — via Google Workspace
✅ Slack — via MCP server
❌ Messages — not connected
If no communication sources are detected, explain what integrations are needed and how to connect them (Settings > Connected apps for Google Workspace, or configure MCP servers in Desktop settings). Then stop.
2. Ask Preferences (First Use Each Conversation)
If this is the first time running in this conversation, ask:
Quick setup for this catchup:
- Which sources to scan? (default: all connected)
- Time window? (default: last 4 hours)
- Any priority contacts to surface first?
Accept brief answers. If the user says "just go" or similar, use the defaults from the Configuration section above.
3. Scan All Sources
For each connected source, gather recent items within the time window:
Gmail:
- Unread emails in inbox
- Emails where the user is in To: (not just CC:)
- Threads with recent replies
Google Calendar:
- Events in the next 4 hours
- Events that started in the last hour (may have missed)
- Events with attachments or agenda docs
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 11d ago First seen · 176 lines · 60 tokens per session scan A 71e309c0b537
inbox-catchup is a skill published in the GitHub repository mostafa-drz/claude-skills (4 stars, last pushed today), licensed MIT. It adds 60 tokens to every session and 1,410 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
Other skills, from other repositories
hydra
Fan multiple independent tasks out to SEPARATE Terminal.app windows, each running its own live claude session with exactly the context it needs — real parallel sessions with isolated context windows, not subagents. Confirms grouping/model/risk with the user before launching, delivers context invisibly, auto-tiles…
shipkit-work-memory
Log session progress and save resume state. Infers from conversation and git. Triggers: 'log progress', 'session summary', 'checkpoint', 'save progress', 'end session'.
session-update
Use when the user says "update session", "log progress", "checkpoint session", or invokes /session-update — especially before /clear or handoff.
interview-kit-builder
Generate a complete structured interview kit for a role — 3-5 role-specific competencies, one behavioral (STAR-format) question per competency, 1-5 scoring rubric with explicit behavioral anchors at each level, per-panel scorecards, interviewer debrief template.
codex-symphony
Install and operate a portable OpenAI Symphony + Linear orchestration setup in any Git repository. Use when the user wants a one-command local Symphony runner, a reusable WORKFLOW template, background launch scripts, or a Codex wrapper that restarts Symphony automatically when reopening the CLI.
claudeshrink
Automatically compress large natural text or log files before processing. Trigger when the user pastes massive text blobs, or asks to analyze a large file (logs, docs, transcripts), or provides a prompt that is too large for the context window. DO NOT trigger on source code files or structural data (JSON, XML).
