catchup

catchup is a skill for Claude Code from oliver-kriska/claude-elixir-phoenix. It costs 48 tokens per session (1,648 once invoked), scanned A, original, MIT.

A catch-up workflow that summarizes what changed while you were away. It reviews repository activity and, when available, related project tickets and meetings, then produces one prioritized brief.

In plain words
What is it for?
Checking missed work after time away, filtering updates by topic or time window, and reviewing activity in one repository or across repositories.
Why use it?
It replaces a scattered review of pull requests, commits, notifications, tickets, and meetings with a single summary focused on what needs attention.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

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 9d 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.

Catchup — Async-Team Return Briefing

You've been away. This skill is a thin orchestrator: it resolves the window + sources here, then delegates the I/O fan-out, impact analysis, and brief assembly to the catchup-runner agent (Sonnet) so your (often Opus) session does not pay for summarization. You only print what the agent returns.

Usage

/catchup                                  # since you were last active
/catchup --since "friday"
/catchup --since "2h" --focus reviews-requested
/catchup --since last-commit --depth deep
/catchup --scope all                      # include cross-repo pings/reviews

Default is repo-scoped: every GitHub signal (reviews requested, notifications, mentions) is filtered to the repo you ran it in. Pass --scope all to also include cross-repo activity, which is then listed in its own separate section — never mixed into this repo's lists.

Iron Laws

  1. Delegate the heavy work — spawn catchup-runner (sonnet) for fan-out + assembly. Do NOT run the gh/git fan-out in this session; that defeats the cost/speed purpose.
  2. Resolve the window here, once — the agent must never re-resolve it. Pass absolute SINCE_* values.
  3. MCP runs here, not in the agent — Linear/Calendar MCP tools are unreliable in subagents. If present, fetch in this context and pass the text to the agent; else mark absent.
  4. Validate --since before any shell — match the grammar; on no match fall back to 24h and note the assumption.
  5. Stop after the brief — print the agent's summary, never auto-transition to another command.
  6. Repo-scoped by default — pass SCOPE=repo unless the user passed --scope all. A brief run inside one repo must not leak another repo's reviews/notifications. Cross-repo is opt-in only.

Workflow

1. Parse arguments

From $ARGUMENTS: --since, --scope, --sources, --depth, --focus. Defaults: --since last-active, --scope repo, all detected sources, --depth standard, no focus. --scope accepts repo (default — every GitHub signal filtered to the current repo) or all (cross-repo allowed, listed in its own section).

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.
