constitution_chat: Skill for Claude Code

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

langgraph-persistence is a skill for Claude Code, Codex from kevyder/constitution_chat. It costs 55 tokens per session (4,351 once invoked), scanned A, original, no licence file.

A guide for adding persistence to LangGraph workflows. Persistence means saving state so a workflow can remember conversations, revisit earlier points, or share the right saved data between subgraphs.

In plain words
What is it for?
Configuring checkpointers, thread IDs, time travel, shared stores, and persistence for LangGraph subgraphs.
Why use it?
It helps workflows retain information across runs instead of losing it when execution ends. It also addresses how saved state is separated and accessed.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is kevyder/constitution_chat's own configuration. It tells Claude Code and Codex how to work on constitution_chat 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 constitution_chat configures →

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.
