claude-session-data-schema-reference

Claude Code session log schema — JSONL record types, message structure, tool call/result pairing, subagent file locations, team session layout, task/plan/team configuration paths. Use when parsing ~/.claude/projects/**/*.jsonl files, writing PostToolUse hooks that measure response sizes, building session analyzers, or any agent that reads or queries Claude session transcripts.

Claude Code Session Log Schema

Reference skill for the JSONL session log format written by Claude Code under ~/.claude/projects/.

All claims in the reference are sourced from direct JSONL file inspection and verified against the LM Assist TypeScript source. No fields are inferred.

When to Load

Load ./references/schema.md when you need:

  • Directory structure and project-key encoding rules
  • Complete record type discriminator (system, user, assistant, result, progress, summary, file-history-snapshot)
  • Field-level schema for each record type
  • Tool call / tool result pairing algorithm
  • Subagent and team session file naming conventions
  • Task, plan, and team configuration paths
  • Hook integration — how PostToolUse tool_response maps to tool_result.content
  • What is NOT in the logs (per-tool token costs, streaming events, hook records, per-tool timing)

Source

Schema verified 2026-03-24. Source reference: ./references/schema.md.

Runs the description-drift experiment — spawns all Claude Code agents simultaneously to collect self-reported capabilities, then compares them against static frontmatter descriptions to reveal how reliable orchestrator routing based on descriptions actually is. Use when measuring description drift across the agent fleet, re-running the capability collection experiment, analyzing a specific agent's self-reported capabilities, or auditing whether frontmatter descriptions accurately reflect agent behavior.
