catchup

A command for catching up on every file changed in the current Git branch compared with the develop branch. It asks the agent to read those files and summarize the changes.

In plain words
What is it for?
Use it to inspect changed files, understand which parts of the codebase were affected, summarize the overall purpose, and identify questions or risks.
Why use it?
It gives a quick overview of work already done in a branch and highlights possible concerns before further development or review.

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.

Made for: Claude Code.

Per session 9 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 135 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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 2d 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.

What it actually says

Catchup on current branch changes

! git diff --name-only $(git merge-base HEAD origin/develop)

Please read all the files listed above that were changed in this branch compared to the base branch (develop). For each file:

  1. Use the view tool to read its contents
  2. Provide a brief summary of what changed

After reviewing all files, give me a concise summary of:

  • What areas of the codebase were modified
  • The overall purpose/theme of these changes
  • Any potential concerns or questions I should be aware of
Changes

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.
