- Lowered the default session scan limit for edits and tools from 100000 to 1000 and updated usage text to match. - Reworked grand-total and per-tool table rendering in session-stats to compute aligned column widths and include an aggregated "(N others)" row. - Tuned the session-stats release profile by replacing full stripping with line-tables-only debug symbols and disabled split debuginfo stripping.
session-stats
Ad-hoc analyses over the local agent session corpus
(~/.omp/agent/sessions/). Single Rust binary with subcommands.
Subcommands
edits — edit-tool reliability audit
Audits how agents have used the edit / ast_edit / write tools.
For each call we:
- detect the argument-schema family in use (the edit tool has shipped many
shapes over time:
oldText/newText,op+pos+end+lines,loc+content,loc+splice/pre/post/sed, etc.); - record the locator shape and verb combination (for the current schema);
- pair the call with its
toolResultand classify the outcome (success/truncated/aborted/fail:anchor-stale/fail:no-match/fail:parse/fail:no-enclosing-block/ …).
Output: markdown-ish report on stdout plus per-call CSV at $EDIT_ANALYSIS_CSV
(default ./edit-analysis.csv).
tools — per-tool token budget
Aggregates token usage across the most-recent N sessions. Buckets:
tool ARGS— assistant tool-call argument JSONtool RESULTS— tool result content textassistant THINKING— assistantthinkingblocksassistant TEXT— assistant proseuser TEXT— user-authored text content
Token counting uses o200k_base via tiktoken-rs (the GPT-4o / GPT-5
family BPE — well-defined offline and within ~5-10% of Claude's own counts in
aggregate across English/code).
Output: grand totals + per-tool breakdown sorted by total (arg+res) tokens.
Optional CSV at $TOOL_USAGE_CSV.
Usage
# Edit audit on the most-recent sessions.
cargo run --release --manifest-path scripts/session-stats/Cargo.toml -- edits
# Edit audit on the 200 most-recent sessions.
cargo run --release --manifest-path scripts/session-stats/Cargo.toml -- edits -n 200
# Edit audit on a specific date.
cargo run --release --manifest-path scripts/session-stats/Cargo.toml -- edits 2026-04-28
# Tool token budget on the 1000 most-recent sessions.
cargo run --release --manifest-path scripts/session-stats/Cargo.toml -- tools -n 1000
# Tool token budget on every jsonl on disk.
cargo run --release --manifest-path scripts/session-stats/Cargo.toml -- tools -n 0
# Dump per-tool CSV alongside the report.
TOOL_USAGE_CSV=tools.csv \
cargo run --release --manifest-path scripts/session-stats/Cargo.toml -- tools -n 200
The walk root is ~/.omp/agent/sessions/. Subagent jsonls
(<session-id>/<n>-<name>.jsonl) count as their own session and are included
in the recency window independently.

The crate is a standalone Cargo project (it carries its own [workspace]
declaration) so it does not perturb the main workspace's lockfile.
