Minimal install

This release ships a package with exactly what the skill needs at runtime, plus the license:

  • opencode-go-model-picker-2.0.0-min.zip → SKILL.md, references/, scripts/, LICENSE

Unzip it into ~/.config/opencode/skills/ (Linux/macOS) or %USERPROFILE%\.config\opencode\skills\ (Windows) so the folder is named opencode-go-model-picker. No dependencies, no build step.

Chinese documentation: README-ZH.md.

[2.0.0] - 2026-10-30

Added

  • references/quota-math.md and scripts/quota-math.mjs: the one priced-accounting
    implementation. Formula v2 prices each assistant message on its own timestamp,
    picks the price by the request's prompt length when a model has context-length
    tiers, applies the peak-hour multiplier only to models that declare one, and
    bills cache writes on the models that charge for them. Reasoning tokens are
    billed at the output rate, checked message-by-message against the provider's own
    per-message cost — omitting them under-prices a message by 4–34%. Derived quantities
    (share of cap, the three independent pool windows, sessions per window, official
    and observed capacity), the pool reverse-solve order, the eight known gaps, and
    the degradation rules for every missing field.
  • references/console-mcp.md and scripts/probe-console.mjs: the five Console MCP
    states (authorized / gated / unauthenticated / absent / unknown),
    decided cheapest-first (in-run tool result → opencode mcp list → config → one
    initialize request), with the fixed per-state guidance copy, the three-level
    fallback, and the enabling steps for the OpenCode CLI and OpenChamber. The probe
    never prints a token and never classifies a network failure as "not set up".
  • scripts/calibrate-usage.mjs: sums the local OpenCode SQLite database per agent
    and model, compares it with the Console's own cost to measure the bias (warning
    when it drifts more than 10%), reverse-solves the plan pool in the documented
    order, projects month-end occupancy from the billing cycle, and — with --write
    — stores plan, models.<id>.billing, usage.agentSplit and calibration in
    the snapshot.
  • references/model-prices.json gained cacheWritePer1M, ctxTiers, capUsd,
    peak, promoUntil and a verified status per model, plus current
    planVerifiedAt dates. It is now the single home of price, cap, context tiers
    and peak hours.
  • Snapshot schema v3: plan.go, models.<id>.billing, availability,
    capabilities (per-capability source + verifiedAt), usage.agentSplit and
    calibration.
  • scripts/discover-agents.mjs now reports a run-level deadChainIds summary
    (missing-from-catalog, retired, registry-missing, registry-deprecated),
    warns on a shared chain head (contention) because the per-model cap is shared,
    and warns per agent when a Go id's catalog status is retired (catalog).
  • references/data-sources.md gained a Console-bill (priority 0) section, a
    two-quota-layer section, official-vs-observed request counts, and a dated
    capability/compliance table (image input, training, retention, availability).
  • quota-math.mjs reports seed freshness — verifiedAt (the newest
    planVerifiedAt / priceVerifiedAt in the table), ageDays and stale — and
    marks a seed older than seven days as expired, so an offline run labels its
    numbers instead of presenting them as current. calibrate-usage.mjs reports the
    same under prices.

Changed

  • The report now opens with a mandatory Basis: line (Console bill (authoritative) / Estimate / Uncalibrated) and one denominator for the whole
    table, and the table columns are the priced ones: headroom, accounted
    $/session (median · P90), share of the model cap, 10 runs as a share of the
    three pool windows, actual monthly occupancy, and why.
  • A new Usage evidence block is mandatory: last-30-days spend and requests, a
    last-7-days pace with a month-end projection, the count of candidates without an
    ELO, the dead chain ids for this run, and the main agents' share of spend.
  • SKILL.md's workflow was reordered to discover → probe Console → read the bill
    and calibrate → refresh the snapshot → detect plan changes → allocate → build
    chains → output → stop, and now ends with nine explicit self-checks.
  • scripts/refresh-prices.mjs reads the cache-write price and the context-length
    tiers from models.dev, and carries the plan-side constants (capUsd /
    monthlyLimitUsd, peak, promoUntil, estReq*, status) through a rewrite,
    so regenerating the seed no longer deletes them.
  • calibrate-usage.mjs --write raises schemaVersion to 3 when it writes v3 keys;
    an existing v2 file is read as-is (every v3 key is optional).
  • references/agent-sources.md states that a native agent.<name>.model cannot
    express a chain, and points at the chain-capable source when failover is wanted.
  • Stale plan facts from the 2026-09/10 verifications were corrected against the
    2026-10-30 plan page (the DeepSeek V4.1 Flash 4x promo is gone; its cap is $80;
    peak/off-peak pricing replaced it).

Breaking

  • Output format: the previous table columns (role overview, capability focus,
    current model) are replaced by the priced columns, and the Basis: line is
    mandatory. A v1 report shape is no longer valid.
  • Snapshot schema v2 → v3. Existing files stay readable, but the new fields are
    absent (hence null) until calibrate-usage.mjs --write runs.
  • references/model-prices.json entry shape grew from 16 to 21 keys; anything
    reading that seed directly must tolerate the new fields.
  • SKILL.md's workflow numbering changed, so any prompt that referred to
    "step 2 = refresh" now points at the Console probe instead.
