In plain words
What is it for?
Use them when developing or reviewing the transcript-saving plugin, including its hooks, Go converter, platform launchers, and Markdown templates.
Why use it?
They give contributors a shared description of the project’s files, architecture, conventions, and templates, making the codebase easier to maintain.

Instructions file for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: reads .claude/ paths; mentions .claude-plugin; mentions Claude Code.

This is IDisposable/claude-transcript-plugin's own configuration. It tells Claude Code how to work on claude-transcript-plugin 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 claude-transcript-plugin configures →

Runs only inside a plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else, and the catalogue could not identify which plugin ships it.

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

claude-transcript-plugin CLAUDE.md 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.

Claude Code Transcript Plugin

Project Overview

A Claude Code plugin that saves readable Markdown transcripts of sessions before context compaction. It hooks into the PreCompact event, reads the session's JSONL transcript, and writes a formatted Markdown file.

Architecture

  • .claude-plugin/plugin.json — Plugin manifest (name, version, metadata)
  • .claude-plugin/marketplace.json — Marketplace catalog for distribution
  • hooks/hooks.json — Registers a PreCompact hook that runs the converter via platform shim
  • scripts/run — Unix shim that detects OS/arch and executes the correct binary
  • scripts/run.cmd — Windows shim for native Windows environments
  • cmd/save-transcript/main.go — Go entry point (reads hook stdin, writes Markdown)
  • internal/transcript/ — Core conversion logic (JSONL parsing, message classification, template rendering)
  • internal/transcript/templates/*.tmpl — Embedded base templates (structural blocks: header, user, assistant, etc.)
  • internal/transcript/templates/tools/*.tmpl — Embedded tool templates (one file per tool, modular/overridable)
  • bin/ — Platform-specific compiled binaries (gitignored, built by CI)
  • skills/save-transcript/SKILL.md — Manual /transcript-saver:save-transcript skill for on-demand use

Key Conventions

  • Only plugin.json and marketplace.json go inside .claude-plugin/ — all other files live at the repo root
  • The hook command uses ${CLAUDE_PLUGIN_ROOT} so paths resolve correctly when installed from the plugin cache
  • The shim scripts detect OS/arch at runtime to support WSL and cross-platform use
  • The converter always exits 0 on error so it never blocks compaction
  • Go 1.26.1+ with no external dependencies (stdlib only)
  • Output goes to ~/.claude/transcripts/ by default, overridable via config/env/flag
  • All settings follow: CLI flag > env var > project config > user config > defaults
  • Config files: <project>/.claude/transcript-saver.json and ~/.claude/transcript-saver.json

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.
