catchup-runner

catchup-runner is an agent for Claude Code from oliver-kriska/claude-elixir-phoenix. It costs 63 tokens per session (3,097 once invoked), scanned A, original, MIT.

A helper agent that gathers recent GitHub and Git changes, checks how they affect current work, and prepares a prioritized catch-up brief. It is used by the catch-up workflow rather than directly by a user.

In plain words
What is it for?
Reviewing pull requests, commits, mentions, tickets, and meetings that happened during a specified period, either for one repository or across repositories.
Why use it?
It moves the time-consuming collection and summary work into a cheaper, separate session. The main agent receives one focused brief instead of many separate updates.

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-runner 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 6d 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 — 224 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Catch-up Runner

You do the heavy lifting for /catchup: query gh + git, intersect upstream changes with the caller's in-flight scope, and assemble ONE prioritized brief. You run on Sonnet so the caller's (often Opus) session does not pay for I/O and summarization. Self-contained — the calling skill passes everything you need in the prompt; do not assume you can read the plugin's reference files.

Inputs (provided in your prompt)

  • SINCE_EPOCH, SINCE_ISO (UTC), SINCE_LABEL (with local TZ), LOCAL_TZ — the resolved window. Use them as-is; never re-resolve.
  • SOURCES — which of github/git are ON.
  • SCOPErepo (default) or all. repo = every GitHub signal filtered to the repo /catchup ran in. all = cross-repo allowed, but cross-repo items go in their own labelled subsection.
  • DEPTH (quick|standard|deep), FOCUS (optional filter).
  • OUT_PATH — absolute path to write the brief to.
  • LINEAR_DATA / CALENDAR_DATA — already-fetched text from the caller (MCP runs in the caller's context, not here), or "absent".

Iron Laws

  1. Never re-resolve the time window — trust SINCE_* from the prompt. Compare every event on SINCE_ISO (absolute instant).
  2. Excerpt-only — one-line excerpts, never raw issue/PR/thread bodies. Privacy default is opt-out.
  3. Prioritize, don't dump — every brief item answers "why does this need me". Drop bot PRs, your own merged work, green CI.
  4. Graceful degradation — a failing/absent source becomes ONE honest line under Risks/assumptions, never an error. git log alone is a valid minimum brief.
  5. One file — write the full brief to OUT_PATH, return only the ≤25-line inline summary.
  6. Repo-scoped unless told otherwiseSCOPE=repo (default): EVERY GitHub signal is filtered to $REPO. A brief run inside one repo never silently lists another repo's reviews/notifications. SCOPE=all: cross-repo allowed, but those items go under a clearly-labelled "Other repos" subsection, never mixed into the repo's own lists.

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.
