From 351635f56dc54ad6e91baa0b210085600107e43e Mon Sep 17 00:00:00 2001 From: Jeremy Schulze Date: Tue, 16 Jun 2026 16:43:58 +0200 Subject: [PATCH] feat(observability): persist LLM token usage and add sin-code tokens CLI MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes #168. The ChatResponse.Usage struct in cmd/sin-code/internal/llm/provider.go:42-46 was parsed but dropped on every LLM call. This wires a pluggable Recorder interface that persists prompt / completion / total tokens + estimated USD cost to a local SQLite database. Components 1. internal/usage/ (new, CGo-free, modernc/sqlite). - Event { SessionID, Model, Source, InputTokens, OutputTokens, TotalTokens, CostUSD, CreatedAt, HasUsage }. - Store: Record, RecordFromChatUsage, Aggregate (group_by day|month|model|source|session), Tail, Count, SetPricing, OpenWithPricing. - DefaultPricing covers NIM / Anthropic / OpenAI / Fireworks; configurable per-model via llm.pricing_per_1k in user config. - Substring fallback for unknown models (longest-key-first match). - 84.5% test coverage, race-safe, concurrent stress included. 2. internal/llm/recorder.go: Recorder interface + NopRecorder default. SessionID flows via context.Context (llm.SessionIDKey{}). Client.Chat now invokes the recorder on non-zero Usage. agentloop/provider_adapter.go captures its tool-call HTTP path via the same recorder (parity with Client.Chat). 3. internal/agentloop/loop.go: threads SessionID into the per-turn context so the LLM client / adapter see the right session. 4. internal/loopbuilder/builder.go: opens the usage store lazily and wires the recorder into the LLM client. Falls back to NopRecorder (no behavioural change) if the tokens.db cannot be opened. 5. sin-code tokens (39 → 40 subcommands): - tokens show [--session ID] [--today] [--month] [--cost] [--share] [--json] - tokens tail [--session ID] [-n 20] - tokens aggregate [--by day|month|model|source|session] [--json] - Caveat: never renders a fake number (caveman discipline). 6. sin-code summary: appends a Tokens: N (in X / out Y) · est. cost: $Z line when usage has been recorded. Migration-safe (legacy sessions still render with HasUsage=false). 7. llm.pricing_per_1k config: flat map. Quoted and unquoted model keys both accepted. 8. Default permission rules: tokens__show/tail/aggregate all allow (read-only local DB; no network, no mutation). Fits M4. 9. Documents: docs/TOKEN-TRACKING.md (data model, CLI, pricing, concurrency). AGENTS.md §6/§7/§11.1 register tokens.db at $XDG_DATA_HOME/sin-code/tokens.db (NOT a gitignored subdir — issue #62 mandates this). CHANGELOG.md Unreleased section updated. Tests - internal/usage/usage_test.go (84.5% coverage, race-safe, 30 cases). - internal/summary/summary_tokens_test.go. - tokens_cmd_test.go (CLI shape, JSON envelope, share line, e2e, missing-db error, pricing overrides). - internal/agentloop/loop_recorder_test.go (verifies SessionID propagation through per-turn context). Hard mandates honored - M2: SQLite via modernc/sqlite, no CGO. - M4: tokens tools default-allow; consumer code (LLM client) never bubbles recorder failures to caller. - M5: github.com/OpenSIN-Code/SIN-Code only. No SIN-Code-Bundle references. - M7: race-safe under go test -race -count=1 (Store.mu guards pricing lookup and ID allocation; sql.SetMaxOpenConns(1) for cheap writes). --- AGENTS.md | 22 +- CHANGELOG.md | 36 + cmd/sin-code/internal/agentloop/loop.go | 6 +- .../internal/agentloop/loop_recorder_test.go | 72 ++ .../internal/agentloop/provider_adapter.go | 22 +- cmd/sin-code/internal/config.go | 48 +- cmd/sin-code/internal/llm/provider.go | 20 +- cmd/sin-code/internal/llm/recorder.go | 69 ++ cmd/sin-code/internal/loopbuilder/builder.go | 20 +- cmd/sin-code/internal/permission_defaults.go | 5 + cmd/sin-code/internal/summary/summary.go | 100 ++- .../internal/summary/summary_tokens_test.go | 113 ++++ cmd/sin-code/internal/usage/store.go | 537 +++++++++++++++ cmd/sin-code/internal/usage/usage.doc.md | 89 +++ cmd/sin-code/internal/usage/usage_test.go | 624 ++++++++++++++++++ cmd/sin-code/main.go | 4 +- cmd/sin-code/summary_cmd.go | 34 +- cmd/sin-code/tokens_cmd.go | 387 +++++++++++ cmd/sin-code/tokens_cmd_test.go | 233 +++++++ docs/TOKEN-TRACKING.md | 136 ++++ 20 files changed, 2537 insertions(+), 40 deletions(-) create mode 100644 cmd/sin-code/internal/agentloop/loop_recorder_test.go create mode 100644 cmd/sin-code/internal/llm/recorder.go create mode 100644 cmd/sin-code/internal/summary/summary_tokens_test.go create mode 100644 cmd/sin-code/internal/usage/store.go create mode 100644 cmd/sin-code/internal/usage/usage.doc.md create mode 100644 cmd/sin-code/internal/usage/usage_test.go create mode 100644 cmd/sin-code/tokens_cmd.go create mode 100644 cmd/sin-code/tokens_cmd_test.go create mode 100644 docs/TOKEN-TRACKING.md diff --git a/AGENTS.md b/AGENTS.md index 69ae5f8e..6b97d297 100644 --- a/AGENTS.md +++ b/AGENTS.md @@ -271,10 +271,11 @@ SIN-Code/ │ │ ├── loopbuilder/ ← v3.4.0: shared factory (DRY) │ │ ├── vane/ ← v3.8.0: HTTP bridge to ItzCrazyKns/Vane (internal/vane) │ │ ├── stack/ ← v3.8.0: unified install/doctor across 3 layers -│ │ ├── hub/ ← v3.12.0: static tool catalog -│ │ ├── ledger/ ← v3.13.0: semantic session ledger (SQLite) -│ │ ├── summary/ ← v3.13.0: deterministic session summary builder -│ │ ├── llm/ ← provider layer + │ │ ├── hub/ ← v3.12.0: static tool catalog + │ │ ├── ledger/ ← v3.13.0: semantic session ledger (SQLite) + │ │ ├── summary/ ← v3.13.0: deterministic session summary builder + │ │ ├── usage/ ← v3.17.0 (#168): LLM token-usage persistence + aggregation + │ │ ├── llm/ ← provider layer (+ Recorder interface, #168) │ │ ├── orchestrator/ ← DAG, critic, adversary, governor, ... │ │ ├── memory/ ← (existing) store/search/embed │ │ ├── lsp/, notifications/, todo/, plugins/, sandbox/, attachments/, webui/ @@ -317,6 +318,11 @@ Lessons DB: `~/.local/share/sin-code/lessons.db` (SQLite, modernc).
