Inspect Claude Code session JSONL files at ~/.claude/projects/ to extract real conversation telemetry: token counts (input/output/cache reads/cache writes), assistant turn counts, human prompt counts, tool-use counts, compaction boundaries, and the contents of compaction summaries. Use this skill when the user asks "how many tokens did this session use", "how many prompts have I sent", "show me the stats for this conversation", "what got compacted", "where are the compaction boundaries…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Claude Session Introspect Claude Code persists every conversation as a JSONL file on disk. This skill is the recipe for opening one and pulling out the numbers you actually want — token usage, prompt counts, compaction events, tool calls — without guessing. ## Where sessions live ``` ~/.claude/projects/<encoded-cwd>/<session-uuid>.jsonl ``` `<encoded-cwd>` is the absolute path of the project's working directory with `/` replaced by `-` and a leading `-`. Example: `/Users/swyx/Work/foo` → `-Users-swyx-Work-foo`. Each line is one event. The interesting `type` values: | type | what it is | |---|---| | `user` | a real user message **OR** a tool result (distinguished by `toolUseResult` being non-null) | | `assistant` | an assistant turn (one model response). `message.usage` has the token counts. | | `system` | system messages (mostly compaction-related) | | `file-history-snapshot` | edited-file snapshots used for undo | | `attachment` | image/file attachments | | `permission-mode` | permission mode toggles | ## Quick locate: find the current session ```bash # 1. encode current working directory ENC="-$(pwd | sed 's,/,-,g' | sed 's/^-//')" …

How to install
mdr add swyxio/skills/claude-session-introspect@sha256:8082a4af11e3db2dThe line at the top of this page pins the label v1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
