…ncode.db OpenCode 2.x keeps credentials in the credential table of opencode.db, next to the sessions; auth.json is gone and a fresh data dir never imports it, so the 1.x plugin reported "not authorized" against a live login and its shadow could not share the user's providers. The plugin now targets 2.x only. auth() reads the provider ids from the credential table through node:sqlite without launching the harness. home() builds the shadow as a snapshot of the user's DB (VACUUM INTO from a read-only connection, every project/session row deleted, no table dropped, ~240 KB) written through a .tmp file, so a resumed turn finds a finished shadow. models() runs the same throwaway ACP handshake grok uses inside a temporary shadow, because `opencode models` starts a persistent background service when none runs and `--standalone` prints nothing in 2.0.20. OPENCODE_PRINT_LOGS=1 keeps the private server's stderr as evidence. extractUsage also reads thoughtTokens and cachedWriteTokens. Node 22.13+ for unflagged node:sqlite. Offline tests cover the snapshot, idempotent resume, and the auth refusals. Verified against opencode 2.0.20: smoke + resume and the cancel probe on zai-coding-plan/glm-5.3-flash, the user's session list and background service untouched.

Codex no longer serves gpt-5.3-codex-spark or the gpt-5.6 pair to ChatGPT accounts; the routing template, the tool description example and the live test's cheap bundle now name gpt-6.1-sol and gpt-6-luna. Claude Fable 5.1 in Claude Code. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

…n be selected OpenCode lists its models before its plugins have added theirs, so a spawn on an OpenCode Go model (or a provider from the user's config) was refused with "model not found" every time. The server announces the full list with config_option_update about a second later. When the model is refused with -32602, the ACP turn now sets it again after each config_option_update, for up to 5 s, and records each retry in the evidence. A model that never appears fails with the harness's own refusal, as before. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

… database OpenCode takes its database path from OPENCODE_DB when it is set. The shadow only changed XDG_DATA_HOME, so with that variable in the user's environment the subagent's session landed in the user's own database, and the login check and the snapshot looked at the default file instead. The login check and the snapshot now read the file OPENCODE_DB names, and the child gets OPENCODE_DB set to the shadow database. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

Version bump for 0.2.0. Minor rather than patch because OpenCode support moved to OpenCode 2 (#6). Ships since 0.1.1: - #5 the newest installed copy of a harness is launched - #6 support OpenCode 2 - #7 OpenCode model is set once, without a retry - #8 Grok's requested model is no longer overridden by launch campaigns - #9 README: the caller's instructions are an inline example Done by Claude Opus 5.5 in Claude Code. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>

OpenCode 2 keeps credentials and sessions in one SQLite file,
opencode.db, and has noauth.json, so the opencode plugin could neither check the login nor build a shadow home. It also lists its models before its plugins have added theirs, so a spawn on an OpenCode Go model (or a provider from the user's config) was refused with "model not found" every time.The plugin now works with OpenCode 2 only.

The user's sessions never reach the shadow and the shadow's sessions never reach the user's lists.OPENCODE_DB. When the user's environment sets it, the login check and the snapshot read the file it names, and the child gets it set to the shadow database, so the subagent cannot write into the user's.-32602, the ACP turn sets it again after eachconfig_option_update, for up to 5 s, and records each retry in the evidence. A model that never appears fails with the harness's own refusal, 5 s later than before. This needs OpenCode 2.0.21 or newer; upstream tracks the remaining gap in acp: set_config_option rejects a configured model selected right after session/new anomalyco/opencode#52472, and the retry can go once that lands.subturn status. Models come from a throwaway ACP handshake in a temp shadow;opencode modelswould leave a background service running. It shows the list the server gives at session start, so late models such asopencode-go/*are not listed even though a turn can select them.cachedWriteTokensandthoughtTokensare read from OpenCode 2's usage records.Node 22.13 is now the minimum, for
