The whole context report: per-session profiles plus cross-session rollups.

Fields

agent: String

since: Option<Date>

sessions_profiled: u64

sessions: Vec<SessionContext>

Per-session profiles, sorted by peak_input_tokens desc (then id).

by_source: Vec<SourceBreakdown>

ESTIMATED transcript-content breakdown across all sessions, sorted desc.

by_server: Vec<ServerBreakdown>

MCP/tool footprint across all sessions, sorted by est_tokens desc.

heaviest: Vec<HeavyItem>

Largest individual contributors across all sessions, sorted desc.

mcp_servers: Vec<String>

Distinct MCP servers actually used (from mcp__<server>__… tool calls).

deferred_tools: u64

Tools available but DEFERRED — not loaded into the window, so not bloat (the max set size seen across deferred_tools_delta attachments).

skills_listed: u64

Skills listed in the window (max across skill_listing attachments).

mcp_instruction_chars: u64

Chars of MCP-server instruction blocks injected into the window.

attachment_chars: u64

Total chars across all attachment lines.

compactions: u64

max_startup_overhead: Option<(String, u64)>

Largest cold-start startup overhead seen (measured), with its session id.
