dev-compact-skills: Hook for Claude Code

.claude/settings.json

PostCompact is a hook for Claude Code from miolamio/dev-compact-skills. Its token cost is not measured, scanned A, original, no licence file.

A post-compaction hook that saves a handoff after the agent's conversation context has been condensed. Context compaction shortens earlier messages so the session can continue within its limit.

In plain words
What is it for?
Use it to run `save-compact-handoff.py` after manual context compaction.
Why use it?
It preserves a continuation note after compaction, when some earlier conversation may no longer be directly available.

Hook for Claude Code

Written for Claude Code: installed under .claude/.

This is miolamio/dev-compact-skills's own configuration. It tells Claude Code how to work on dev-compact-skills itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything dev-compact-skills configures →

One of 5 entries in settings.json upstream. Installing this one merges just its entry into your config; the other 4 are separate, each on its own page.

Security

Grade A, and why

PostCompact 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 2mo ago.

A static scan of the commands this hook runs, not an audit. A hook is shell that executes on your machine at the event it names, which is why every command in it is printed with what was found.

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 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.
