- Updated the hashline mismatch error to describe anchor mismatches against the current file. - Rewrote hashline tool instructions to clarify insert payload rules, anchor usage, and avoidance of fabricated hashes. - Expanded stale-edit detection and tests to recognize the revised anchor-mismatch rejection wording.
session-stats
Ad-hoc analyses over the local agent session corpus
(~/.omp/agent/sessions/). SQLite-backed; data is synced once into the same
~/.omp/stats.db that packages/stats uses, then queried by short Python
scripts.
Layout
scripts/session-stats/
sync.py # walks ~/.omp/agent/sessions/ and populates ss_* tables
analyze.py # tools | edits | followups subcommands over the synced db
One-time prep
pip install tiktoken
Sync
bun run stats:sync # incremental
python3 scripts/session-stats/sync.py --workers 16 --full # rebuild all
python3 scripts/session-stats/sync.py --limit 200 # newest 200 only
The sync is incremental: per-file mtime, size, byte_offset, and
parser_version are tracked in ss_sessions. Re-runs only parse new bytes
and only re-tokenize / re-classify what changed. A bump of EDIT_PARSER_VERSION
in sync.py invalidates ss_edit_* rows on next sync.
Tokenization is o200k_base (GPT-4o / GPT-5 family) via tiktoken — well
within ~5–10% of Claude's BPE in aggregate.
Schema
All tables are prefixed ss_ to avoid collision with packages/stats.
| Table | Granularity |
|---|---|
ss_sessions |
one row per .jsonl; carries sync state + session metadata |
ss_tool_calls |
one row per toolCall content block (arg_json, arg_tokens) |
ss_tool_results |
one row per toolResult message (result_text, result_tokens, is_error) |
ss_assistant_msgs |
per assistant message text + thinking blobs and token counts |
ss_user_msgs |
per user message text and token count |
ss_edit_calls |
per edit call: success, warnings, raw_input_len |
ss_edit_sections |
per @PATH section in an edit; precomputed longest_repeat_*, dup_anchors |
Indexes on (tool_name, timestamp) and (session_file, seq) make per-tool
aggregations and ordered session walks cheap.
Analyses
bun run stats:tools # per-tool token totals
bun run stats:tools -- --by d --top 8 # bucket by day, top 8 tools each
bun run stats:edits # edit-tool reliability audit
bun run stats:followups # five hashline-edit detectors
bun run stats:followups -- --max-fix 2 --min-dup 8 --show 20
All three accept -n N / --folder SUBSTR to scope the query.
The Rust crate that previously lived here was retired in favor of this SQLite-backed flow. The schema persists everything the analyses used to recompute on every run (token counts, hashline parse output, success flags), so subsequent invocations are sub-second over the full corpus.
