session

session is a plugin for Claude Code from ericfitz/skills. Its manifest loads nothing; the 2 skills it bundles cost 196 tokens per session together, scanned A, original, Apache-2.0.

A session-continuity toolkit that stores the current coding state in HANDOFF.md and checks that file against the live repository when work resumes. A session is one period of work with the coding agent.

In plain words
What is it for?
It helps save a checkpoint, resume interrupted work, detect changes since the checkpoint, and remind the agent to resume when a handoff file exists.
Why use it?
It reduces confusion between what the previous session recorded and what is actually present in the repository.

Security

Grade A, and why

session 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 10d 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

{
  "name": "session",
  "version": "1.0.0",
  "description": "Session continuity toolkit: write a machine-local HANDOFF.md holding only current state (handoff) and resume from it by checking it against live repo facts, reporting drift, and stopping before any work starts (continue). A SessionStart hook reminds Claude to run continue when a HANDOFF.md exists."

What it installs

The manifest is a name and a version. 2 skills travel with it, and installing the plugin installs all of them — 196 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
