Summary

Adds OmO as a first-class local source, tracked separately from oh-my-pi (omp) and pi.

OmO writes the same append-only JSONL sessions as oh-my-pi:

~/.omo/agent/sessions/--<cwd-encoded>--/<timestamp>_<sessionId>.jsonl

This change generalizes the existing omp reader (parseOmpLikeIncremental) instead of duplicating it. omp and omo differ only in:

oh-my-pi OmO
Home ~/.omp ~/.omo
Cursor / source omp omo
Reasoning field usage.reasoningTokens usage.reasoning
PI_CONFIG_DIR / PI_CODING_AGENT_DIR honored (shared with pi) not honored

PI_* env vars stay with pi/omp. Routing them to a third provider would reintroduce the collision decidePiCodingAgentDirOwner exists to prevent. Overrides are TOKENTRACKER_OMO_AGENT_DIR / TOKENTRACKER_OMO_HOME / OMO_HOME.

Costing

OmO reports reasoning as a subset of output, and totalTokens excludes it (input + output + cacheRead + cacheWrite === totalTokens). Its own usage.cost has no reasoning component.

So OmO follows the Codex convention: reasoning_output_tokens is informational and must not be billed on top of output (computeRowCost + the token-audit invariant).

Dashboard

  • Display name OmO (copy key + zh / zh-TW)
  • Brand mark at dashboard/public/brand-logos/omo.svg
  • Listed in AGENT_LOGOS so the marketing tool strip picks it up

Out of scope

  • No notify extension (omp-hook equivalent). Passive session scan is the source of truth; tokentracker serve already periodic-syncs.
  • No change to resolveKilocodeRoots (split(":") on Windows). That is a pre-existing test issue on drive-letter paths, unrelated to this source.

Test plan

  • test/omo-parser.test.js — field spelling, totalTokens exclusive of reasoning, independent omp/omo cursors, path overrides, scan layout, no double-billing
  • Provider display + ProviderIcon tests
  • validate:copy, validate:locale, validate:ui-hardcode, validate:guardrails
  • Live parse of a real ~/.omo install (separate omo buckets, omp totals unchanged)

Summary by CodeRabbit

  • New Features
    • Added support for tracking OmO sessions, subagents, and passive activity.
    • Added OmO to automatic synchronization, status reporting, onboarding, dashboards, and supported-tool listings.
    • Added Traditional and Simplified Chinese display translations.
  • Bug Fixes
    • Prevented duplicate counting when OmO and OmP use the same agent directory.
    • Corrected OmO reasoning-token handling to prevent inaccurate totals and double billing.
  • Documentation
    • Updated documentation and marketing content to reflect 35 supported tools and document OmO configuration options.

OmO persists the same JSONL session format as oh-my-pi, so this reuses the
omp parser with a separate home, cursor namespace, and source label.

Reasoning is spelled `reasoning` (not `reasoningTokens`) and is a subset of
output — bill it like Codex, not as extra output cost.

📝 Walkthrough

Walkthrough

OmO support was added for passive session discovery, incremental parsing, synchronization, status reporting, token accounting, dashboard display, CLI onboarding, metadata, and documentation. The supported tool count increased from 34 to 35.

Changes

OmO integration

Layer / File(s) Summary
OmO provider resolution and parsing
src/lib/rollout.js, test/omo-parser.test.js
Shared pi-style utilities support OmO session paths, subagent files, cursors, source buckets, reasoning fields, project attribution, fallback totals, and collision checks.
Synchronization and status wiring
src/commands/sync.js, src/commands/status.js
Sync discovers and parses OmO files, avoids OmP path collisions, reports progress, and includes OmO counts. Status output reports OmO installation and session files.
OmO token accounting
src/lib/pricing/index.js, scripts/audit-token-correctness.cjs, test/omo-parser.test.js
OmO reasoning tokens are treated as informational and as included in output for total-token checks and cost calculation.
OmO provider identity and catalog wiring
dashboard/src/..., src/commands/init.js, scripts/validate-locale-coverage.cjs
OmO display copy, provider formatting, marketing logo metadata, locale validation, and CLI onboarding entries were added.
OmO documentation and metadata
README*.md, dashboard/index.html, dashboard/public/llms.txt, package.json, test/discovery-metadata.test.js
Documentation and metadata now list OmO and report 35 supported tools across supported locales and catalog surfaces.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 59b15

OmO can currently overcount usage when reasoning tokens are present, show misleading active status after a source collision, and duplicate attribution if its directory override points to Pi’s sessions. The PR should address these bounded correctness and reporting risks, or obtain explicit owner acceptance, before merge.

12366-12370: 🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Exclude OmO reasoning from fallback totals.

When usage.totalTokens is absent, both fallback expressions add reasoningTokens. For OmO, reasoning is already included in output. This inflates total_tokens and billable_total_tokens in persisted main and project buckets.

Pass a reasoningIncludedInOutput option from parseOmoIncremental, and omit reasoning from both fallback sums when it is true. Add a test with OmO reasoning and no totalTokens.

Add a consecutive OmO sync regression test.

parseOmoIncremental stores each file’s size and inode in cursors.omo.fileOffsets. It skips unchanged files on the next sync, so it queues no new buckets and preserves existing totals. The OmO tests do not cover this behavior.

434-437: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Apply the OmO/omp collision guard to status detection.

When the OmO agent directory collides with the omp agent directory, sync skips OmO. This code still reports OmO as installed and lists its files in status --json, status --light, and normal status output.

Use omoAgentDirCollidesWithOmp(process.env) when computing omoInstalled and omoFiles, as the pi status path does.

Remove the OmO README icon from the dashboard. Keep the OmO source
integration and bump the canonical tool count (init, package.json,
localized READMEs, JSON-LD, llms.txt) so discovery-metadata tests pass.

I rechecked exact head 59b15124fd76436a2fd2fb360b428b1f41e3c3f2. The later commits appear to address the earlier OmO/OMP collision and reasoning-fallback findings, so I am not repeating those items.

The current branch is now DIRTY against the latest main after today's merges and v0.93.5 work. GitHub cannot construct a merge result, and the green checks are for the pre-integration head rather than a current-main merge. Please rebase or merge the latest main, resolve the conflicts, and push the resulting head; CI must rerun on that exact integration before semantic merge review can finish.

Conclusion: NO-MERGE until the branch integrates cleanly with current main.

The approach is right and the accounting homework is the part most new-provider PRs skip, so this is close. It needs a rebase before I finish the review — the branch conflicts with main.

What's already correct.

  • The reasoning question is answered with evidence, not assumption. input + output + cacheRead + cacheWrite === totalTokens across 2,586 messages, with no separate reasoning component in usage.cost, is what justifies reasoningIncludedInOutput: true. Getting this wrong is how Codex/every-code inflated cost 6–7× before, so the corpus check is the right bar.
  • Factoring parseOmpLikeIncremental out instead of copying the omp parser, with the reasoning spelling as a per-provider reasoningFields list rather than a both-spellings guess.
  • omoAgentDirCollidesWithOmp, and deliberately not honoring PI_CONFIG_DIR / PI_CODING_AGENT_DIR. Routing a third provider through the dir that decidePiCodingAgentDirOwner exists to disambiguate would have been a real bug.

Rebase. The provider count in the five READMEs, dashboard/index.html, and llms.txt moves whenever a source lands on main, so recount rather than resolving to your number — it's an exhaustive search, the count appears in more places than the conflict markers will show you.

One non-blocking note for the follow-up. entryId is OmO's 8-hex id, and seenIds is capped at 10,000. Within one window that's roughly a 1% chance of a birthday collision, and a collision means the message is silently skipped, not double-counted. This is inherited from the existing omp parser, not introduced here, so it isn't a blocker for this PR — but since you're the one touching this code path, it's worth checking whether OmO exposes anything longer, or whether keying on sessionId + id is cheap here.

Push the rebase and I'll review the parser and the 323 lines of tests against the exact head.
