+The CLI reads your local [ccusage](https://github.com/ccusage/ccusage) data (cost, tokens, models, sessions), uploads it to Straude, and auto-creates a post on your feed. That includes all 16 built-in sources in the bundled ccusage 20.0.20 release: Claude Code, Codex, OpenCode, Amp, Droid, Codebuff, Hermes Agent, pi-agent, Goose, OpenClaw, Kilo, Kimi, Qwen, GitHub Copilot CLI, Gemini CLI, and Grok Build CLI. First run opens a browser login; after that, just run `npx straude@latest` daily. It automatically pushes new stats since your last sync.
 
 Options: `--date YYYY-MM-DD` to push a specific date, `--days N` to backfill the last N days (max 7), `--dry-run` to collect usage without submitting it. Run `npx straude@latest status` to check your streak and rank.

 ### Changed
 
+- **Track all 16 coding-agent sources released in ccusage 20.0.20.** Straude CLI 0.1.31 raises the dependency floor and lockfile to 20.0.20, adding Grok Build CLI to the existing unified collector. Gemini-only, Qwen-only, Grok-only, and mixed synthetic sessions now run through the real bundled binary in regression tests. Tests verify source IDs, token buckets, reasoning, and model costs, and the API tests store row-specific metadata for every released source. CLI documentation and public product guidance describe the broader support. Join pages and share images use "AI coding" so Gemini, Qwen, and other usage is not mislabeled as Claude Code. Mistral Vibe remains an upstream collector gap.
+
 - **Extracted `ActivityCard`'s hardcoded model chip colors** into `apps/web/lib/constants/model-colors.ts`, which now owns the whole name-to-colour decision (`modelColor`) rather than exporting raw tables for callers to recombine. Same colors, same matching order, per the design-system-consistency roadmap item.
 
 - **All ccusage sources and the OpenAI GPT-5.6 family are now tracked.** The CLI dependency floor is `ccusage@20.0.16`, the first release with `gpt-5.6`, `gpt-5.6-sol`, `gpt-5.6-terra`, and `gpt-5.6-luna` plus request-level long-context pricing. Collection now uses current online LiteLLM pricing by default, avoiding stale embedded-price estimates. Unified rows are no longer filtered to Claude/Codex: Straude accepts every source ID emitted by ccusage, carries each row's source IDs through submission metadata, and retains source-aware handling for trusted Codex corrections. A real bundled-binary fixture locks the four GPT-5.6 variants to 440,000 total tokens and asserts that every variant resolves to a non-zero LiteLLM price, with the day total equal to the sum of the per-model breakdown. The dollar amounts themselves are owned upstream and move without notice, so they are deliberately not pinned.

 # Architecture & Design Decisions
 
+## Follow released ccusage source support through the unified collector (2026-09-04)
+
+**Decision:** Raise the bundled dependency and runtime floor to ccusage 20.0.20. Keep the existing source-agnostic daily report and metadata pipeline. Its released native binary exposes 16 coding-agent sources, including Gemini CLI, Qwen, and Grok Build CLI. Antigravity and ZCode appear on upstream main but are absent from this release; Mistral Vibe remains unsupported.
+
+**Alternatives considered:** (a) Add separate Gemini/gemistat, Qwen, and Mistral parsers as proposed in PRs #77 and #22. This could add an unsupported agent sooner, but duplicates parsing, deduplication, pricing, and maintenance. (b) Upgrade the unified collector and test its released source inventory. Chosen because Gemini and Qwen already work through this path, Grok needs only the dependency update, and the API already preserves dynamic source IDs. Mistral support should first land upstream.
+
+**Presentation:** Join-page text and share images use "AI coding" instead of inferring Claude Code or Codex from model names. Other agents can use the same models, so that inference mislabels their usage. Reading source metadata would allow specific labels but would add data queries to a copy fix; generic wording is accurate with the existing data.
+
+**Evidence and limits:** Native binary fixtures cover Gemini, Qwen, Grok, and a mixed day without Claude or Codex logs. They check cache buckets, reasoning totals, source metadata, and nonzero per-model prices. Grok's recorded USD ticks are checked exactly. The source inventory test compares all 16 documented IDs with installed binary help, and API tests check each ID independently. Tests run with an isolated child environment and synthetic logs. They do not prove every upstream parser or real provider billing. No database migration or extra collector is needed.
+
 ## Route sensitive mutations through the server service client (2026-08-27)
 
 **Decision:** Publishable Supabase roles retain only the reads and narrow self-service updates the browser needs. Security-sensitive writes go through authenticated API routes, which validate ownership and input before using the server service client. `SECURITY DEFINER` functions authorize their callers or restrict execution to the service role; public read RPCs expose explicit fields, enforce ownership joins, and bound batch and pagination work.

-### Surface Multi-Agent CLI Support
+### Complete Multi-Agent Presentation and Upstream Coverage
 
-Straude already ingests usage from far more than Claude Code and Codex, and nobody knows it. The CLI shells out to `ccusage daily --json` with no source scoping (`packages/cli/src/lib/ccusage.ts:454`), and `ccusage@^20.0.16` detects Gemini CLI, Qwen, Kimi, GitHub Copilot CLI, Amp, Droid, OpenCode, Goose and others. Nothing downstream is hardcoded: `CcusageAgent` is `string`, agent names come from `metadata.agents` per row, and `/api/usage/submit` only checks that they are non-empty strings — no allowlist.
+The CLI now documents all 16 released ccusage 20.0.20 sources. Real binary fixtures cover Gemini CLI, Qwen, and Grok Build CLI, including users without Claude or Codex logs. The landing explanation and agent-readable guidance describe this broader support.
 
-Discovered while triaging PRs #77 and #22, both of which hand-wrote parsers for capability the collector already has. Work to make it real to users:
+Remaining work:
 
-- `prettifyModel` cases for Gemini, Qwen, Kimi and Copilot model IDs, so they read as product names rather than raw slugs.
-- Deliberate entries in `MODEL_COLOR_PATTERNS` for those families, so they get a chosen colour instead of a hashed one from the fallback palette.
-- Landing-page and README copy naming the supported agents. "Works with your whole toolkit" is a stronger acquisition line than "works with Claude Code", and it costs no engineering.
-- Mistral Vibe is the one real gap — it is not a ccusage source. Best path is upstreaming it to ccusage rather than carrying a Straude-local parser.
+- Add `prettifyModel` cases and deliberate model colors for Gemini, Qwen, Kimi, and other families. These affect presentation; collection already accepts their source IDs and model names.
+- Upstream Mistral Vibe parsing to ccusage, then upgrade the bundled release and add a synthetic native-binary fixture. PR #22 proposed a local adapter, but ccusage 20.0.20 has no Mistral source. Preserve token accounting and model pricing in upstream tests before advertising support.
+- Upgrade when Antigravity and ZCode ship in a published ccusage release. They are present on upstream main but absent from 20.0.20. Extend the native source inventory and add fixtures when adopted.

+
+## Supported coding agents
+
+The bundled ccusage 20.0.20 release detects all 16 sources by default: **Claude Code, Codex, OpenCode, Amp, Droid, Codebuff, Hermes Agent, pi-agent, Goose, OpenClaw, Kilo, Kimi, Qwen, GitHub Copilot CLI, Gemini CLI, and Grok Build CLI**. You can sync any one source or combine several on the same day. Claude Code and Codex are optional.
+
+For example, Gemini CLI sessions under `~/.gemini/tmp`, Qwen chats under `~/.qwen/projects`, and Grok sessions under `~/.grok/sessions` are collected automatically. ccusage also respects `GEMINI_DATA_DIR`, `QWEN_DATA_DIR`, and `GROK_HOME` overrides. Run `npx straude@latest --dry-run` to inspect collected totals before submitting them.
+
+Straude preserves source IDs emitted by ccusage, including compatible custom IDs and sources added by later compatible releases. This does not add parsers for unsupported agents: **Mistral Vibe is not a built-in source in ccusage 20.0.20**. Support follows the installed collector release, not unreleased upstream documentation. See the [ccusage 20.0.20 source adapters](https://github.com/ccusage/ccusage/tree/v20.0.20/rust/adapters).

+# Synthetic ccusage source fixtures
+
+These records were written for Straude tests. They contain invented session IDs and token counts, with no prompts or real user usage.
+
+Shapes follow the [ccusage v20.0.20 adapters](https://github.com/ccusage/ccusage/tree/v20.0.20/rust/adapters):
+
+- Gemini: cached input is included in the input count and identified through the total; thoughts are separate output tokens.
+- Qwen: prompt, cached, candidate, and thought token counts are separate buckets in the upstream adapter.
+- Grok: cache reads and writes are subsets of input; reasoning is a subset of output. Recorded `costUsdTicks` use units of 1e-10 USD, so 123,000,000 ticks equals $0.0123.
+
+The test supplies one source root at a time, then all three roots. Its child environment excludes inherited source paths, configuration, and pricing caches. Offline embedded prices keep source parsing tests independent of the network; the separate GPT-5.6 test checks online pricing.
+
+`../ccusage-sources.json` lists the 16 source IDs exposed by the released native binary. It is shared with CLI parser and API tests. The native help comparison must change when a dependency update adds another built-in source.
