workshop-agent-harness: Skill for Claude Code

.claude/skills/langgraph-persistence/SKILL.md

langgraph-persistence is a skill for Claude Code from caio-moliveira/workshop-agent-harness. It costs 55 tokens per session (4,345 once invoked), scanned A, original, no licence file.

A guide to saving and restoring the state of a LangGraph application. This lets an application remember conversations, revisit earlier points, or share stored data with parts of a graph.

In plain words
What is it for?
Use it when a LangGraph app needs conversation history, checkpoints, time travel, or persistent data. It covers checkpointers, thread IDs, Store, and subgraph persistence modes.
Why use it?
It helps workflows continue after interruptions and prevents conversation or process state from being lost between runs. It also explains how stored state is scoped across subgraphs.

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

langgraph-persistence 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 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.

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.
