The Usage page only aggregated Claude Code, Codex, and Grok Build; OpenCode turns were invisible even for users whose main driver is OpenCode. Follows the existing scan pattern: the environment reads OpenCode's own on-disk store rather than T3 Code's projections. OpenCode keeps every message as a row of the 'message' table in <data dir>/opencode.db, so the scan opens the database read-only (WAL-safe against a running OpenCode), folds rows through a pure parser, and reports a 'failed' source when the store cannot be read. The data dir resolves per OpenCode's own XDG rules. No scan-cache or resume machinery: the window filter runs in SQL and a retried turn updates its row in place, so there is nothing to dedupe. Legacy pre-SQLite storage/** JSON is deliberately not scanned: current OpenCode reads and writes only the DB, and scanning both would double count on migrated machines. USAGE_CONTRACT_VERSION bumps to 6; USAGE_MERGE_COMPATIBLE_SINCE stays at 4 because the change is additive, so older environments keep merging. Model: openrouter/z-ai/glm-5.3-flash. Harness: OpenCode (T3 Code).

…t loop CodeRabbit flagged that readOpenCodeUsageRecords ran the synchronous node:sqlite query and every row's JSON.parse in one blocking slice; Effect.promise offloads nothing, so a years-deep store would freeze the server loop behind a usage page load. Reads now walk rowid pages (direct B-tree seeks, no OFFSET rescan) of 1000 rows and yield to the macrotask queue between pages, the same interleaving the streaming JSONL reader gets from its I/O awaits. time_created carries no index, so it is filtered per row in the page loop. Model: openrouter/z-ai/glm-5.3-flash. Harness: OpenCode (T3 Code).

CodeRabbit flagged that rowid paging returned insertion order, and a backfilled or clock-adjusted message can hold a later rowid with an earlier time_created. Records are now sorted by time_created with rowid as the tie breaker before returning, keeping the paging cursor and its loop yields. Model: openrouter/z-ai/glm-5.3-flash.

Tested review: ran this parser against a live OpenCode store
Read the branch, lifted parseOpenCodeMessageData + your paging loop verbatim (run with node --experimental-strip-types), and ran it over a real 134 MB ~/.local/share/opencode/opencode.db (OpenCode 1.18.18, 760 message rows, 700 assistant, 688 with tokens, 52 sessions, every turn routed to OpenRouter):
records 688 uncachedInput 2,110,352 cachedInput 76,603,812
cacheCreation 3,796,001 output 243,674 reasoning 84,484
costUsd 17.6783 unpricedRows 0
Those input/cache/cost figures match an independent aggregation of the same DB field for field. Paging, ordering, the zero-token skip and the cost > 0 rule all behave as documented (12 all-zero-token rows skipped, 0 rows missing modelID/time.created). volumeId = readDirectoryVolumeId(dir) in collectDirs also gives you the same cross-environment dedupe the other providers get — good.
Two things I would fix before merge:
1. reasoningTokens: Math.min(outputTokens, reasoning) drops real tokens. The doc comment says reasoning is reported inside tokens.output, but in this store that is not true: 173 of 688 rows have reasoning > output (e.g. input=7065 output=32 reasoning=70; across just those rows output sums to 48,745 while reasoning sums to 222,888), so reasoning cannot be a subset of output. The clamp silently discards 174,143 tokens here — the store says output 243,674 / reasoning 258,627, the reader reports output 243,674 / reasoning 84,484. #10409 maps it additively (outputTokens: tokens.output + reasoningTokens), which keeps the contract's "reasoningTokens is a subset of outputTokens" invariant true instead of clamping. Either way, please make the code agree with the contract rather than with the comment.
2. session_message is not read — and it is the v2 write path. The shipped 1.18.18 binary creates session_message (with its own session_message_time_created_idx) and carries the migrations …_reset_v2_session_state, …_session_message_projection_order, …_event_sourced_session_input; the store I tested has the table present but empty. If a build starts projecting turns there, this reader returns ok with 0 records and the page renders an empty OpenCode band with no source error to explain it. #10409 reads message ∪ session_message and also globs opencode-*.db; matching that coverage would make this forward-safe.
Non-blocking observations:
- The whole
messagetable is re-walked on every scan. Your paging +setImmediateyield keeps the event loop safe, but Claude/Codex/Grok files get(size, mtime)memoisation throughusageScanCacheand this store gets none. Memoising by(db size+mtime, -wal size)or folding it into the same cache would keep a years-deep store cheap. - The window filter uses
row.time_createdwhile the record timestamp comes fromdata.time.created— two clocks, so a row near the boundary can be filtered out by one and stamped by the other. Harmless today, but worth making one source of truth. cost > 0 → reportedCostUsd, else nullis the right call: OpenCode writes0for turns it has no rate for, and the rate table estimates those better than a confident$0.00.
Net: the reader is correct on everything it counts, it just drops the reasoning tokens and has one forward-compat gap. Fix those two and I would call it mergeable.

Follow-up with a hard proof for the reasoning point, because the store settles it on its own. In a real 134 MB So |
The scan kept only opencode-go rows on the theory that ChatGPT OAuth turns were already counted by the Codex rollout scan. They are not: opencode's openai plugin talks to the ChatGPT backend itself and writes no rollouts, and Zen and OpenRouter turns have no other home either. Count every assistant row opencode stores. opencode writes cost 0 when it has no rate for the model, so treat 0 as unknown and let the rate table price the tokens instead of reporting $0. Both calls come from AmoonPod's research on the same store in pingdotgg#10926, which verified the token accounting and cost semantics against real databases.

Hey @AmoonPod, heads up that I didn't find this PR when I started on the same thing a few days back. I just published mine (#11783) and CodeRabbit flagged yours. Mine also adds the OpenCode Go quota card under Limits, reads both message tables opencode keeps, and handles partial and failed scans, so I'm hoping to land that one. But your research on the store was better than mine. I had a wrong assumption about the OAuth rows and was undercounting, and your zero-cost handling was the right call. I pulled both into my branch and credited you in the commit. If you'd rather bring those over as your own commits, or think there's a better way to combine the two, I'm open to it. Just say. |

What Changed
OpenCode is now a first-class usage source, following the exact playbook the grok addition (v5) used:
UsageProviderKindgains"opencode".USAGE_CONTRACT_VERSIONbumps to 6;USAGE_MERGE_COMPATIBLE_SINCEstays at 4 because the change is additive, so v4/v5 environments keep merging instead of showing stale.parseOpenCodeMessageDatareducer plus a newopencodeUsageStorethat reads OpenCode's own message store (<data dir>/opencode.db,messagetable) read-only vianode:sqlite- WAL-safe against a running OpenCode, no scan-cache/resume machinery (the window filter runs in SQL; a retried turn updates its row in place, so there is nothing to dedupe).UsageServiceresolves the data dir per OpenCode's own XDG rules and reports a newfailedsource status when the store cannot be read, distinct frommissing.PROVIDER_PRESENTATIONentry (existingOpenCodeIcon); charts, tables, environment filter, and cross-environment duplicate-source dedup adapt viaPROVIDER_ORDERand fingerprints.PROVIDER_ORDER/labels/colors extended, with a light-mode-safe indigo.docs/user/usage.mdprovider list mentions OpenCode.Token mapping was verified against real stores: OpenCode's

OpenCode appears as a new band/row in the web charts and tables and in the mobile chart, using an indigo accent (the only hue in the otherwise white/orange/gray palette). Can add before/after screenshots on request.
