Address latest review comments from sky5454 in PR #2654.
scripts/copydir.go:
- Improve repository root detection in a safer, more deterministic way.
- Prefer locating repo root from the script source path via runtime.Caller(), then fallback to upward search from current working directory.
- Replace .git-only root detection with repository anchor validation: go.sum, LICENSE, and .github must exist.
- Keep \ placeholder expansion and existing in-repo path guards.
- Preserve destination safety check to prevent deleting/copying to repo root.
web/backend/api:
- Rename applyLauncherWindowsProcAttrs() to applyLauncherProcAttrs() to expose a platform-independent interface name.
- Keep platform-specific behavior split by build tags: windows keeps HideWindow SysProcAttr setup, non-windows remains no-op.
- Update gateway startup path to call the renamed helper.
Why:
- Follow reviewer feedback to avoid relying on .git detection alone and prefer runtime/file-anchor based repository location.
- Improve naming clarity by making cross-platform interfaces generic while preserving OS-specific implementation details internally.
Validation:
- go test ./cmd/picoclaw/internal/onboard
- go test ./web/backend/api
* Fix Windows build flow
* build(makefile): make windows recipes shell-safe
- avoid backslash line-continuation in Windows build-launcher recipe
- replace cmd-specific if-not-exist with PowerShell check in web build-frontend
* Fix Windows build flow
* build(makefile): make windows recipes shell-safe
- avoid backslash line-continuation in Windows build-launcher recipe
- replace cmd-specific if-not-exist with PowerShell check in web build-frontend
* build(web): avoid shell-expanding powershell vars in windows recipe
- rewrite build-frontend Windows command without PowerShell local vars
- keep install-stamp hash check logic
The launcher wired UI language changes into a process-global backend
switch that changed auto web-search provider selection and the
reported current service for every handler in the same process.
This narrows the fix to the validated leak: remove backend sync from
frontend locale changes, drop the now-unused UI endpoint, and make
auto selection fall back to a stable default when the query itself
does not contain a script hint.
Constraint: Keep the patch small and mergeable without redesigning per-user preference storage
Rejected: Add per-user backend language state | larger scope than the validated bug and unclear maintainer preference
Rejected: Persist preferred language in config | still shares mutable state across clients of the same instance
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: If locale-aware provider routing is reintroduced later, scope it to explicit config or request context instead of package-global state
Tested: go test ./web/backend/api ./pkg/tools -count=1; pnpm lint; pnpm build
Not-tested: Full make check; live multi-browser manual launcher run after the backend endpoint removal
- centralize web search provider readiness and resolution logic
- fall back when the configured provider is unavailable or invalid
- allow native-search-capable models to use built-in search without the client tool
- simplify the tools page and add direct access to web search settings
- add backend, agent, and integration tests for the new selection behavior
* refactor: support explicit model list providers
* fix(web): preserve explicit model providers
* fix(web): preserve legacy provider prefixes on model updates
fix(models): normalize explicit provider-prefixed ids
fix(api): preserve legacy model updates across providers
fix(agent): preserve config identity for explicit provider refs
* fix ci
* feat(web): download attachments in frontend
* fix: proxy pico media and force svg downloads
* feat(web): hide ephemeral media refs from persisted session history
Add a context window usage indicator to the web chat UI and a /context
slash command that works across all channels.
Backend:
- Add computeContextUsage() estimating history + system + tool tokens
- Attach ContextUsage to outbound messages via the pico WebSocket protocol
- Add /context command showing context stats as formatted text
- Add EstimateSystemTokens() on ContextBuilder for system prompt estimation
Frontend:
- Add ContextUsageRing component (SVG ring + hover/tap popover)
- Show usage percentage, token counts, and compression threshold
- Hover on desktop (150ms leave delay), tap on mobile
- "View Details" sends /context with 1s cooldown
- i18n support (en/zh) for popover labels

Add reusable channel array list controls and parsing utilities for channel forms.
Normalize channel string-array payloads in the backend, including pasted values,
numeric IDs, hidden characters, duplicates, and empty clears.
Also allow FlexibleStringSlice to unmarshal null values and cover the new behavior
with backend and config tests.
Filter raw tool messages from session history and avoid duplicate summaries for visible message-tool output. Preserve final assistant replies after tool delivery and add coverage for visible transcript counts.
Also refine the chat UI with collapsible reasoning blocks, send shortcut hints, command-style user messages, stable scroll gutters, and updated i18n strings.
- stop exposing the raw Pico token to the frontend
- add /api/pico/info for non-secret Pico connection metadata
- proxy /pico/ws through the launcher with same-origin and dashboard auth checks
- inject the upstream Pico websocket protocol server-side
- update frontend chat connection flow and Vite websocket proxy path
- refresh related docs and tests
* refactor(docs): reorganize docs by type and locale
* chore(docs): add docs layout lint target and contributor guidance
Introduce a lint-docs script and Makefile target for common
documentation naming and placement checks. Expand docs/README.md
with layout and translation conventions, and update CONTRIBUTING.md
to point contributors to the new docs guidance and validation step.
* docs: add section index pages and fix localized doc links
- add reader navigation to docs/README.md
- add index pages for guides, reference, operations, security, architecture, and migration
- update localized project README links to prefer existing translated docs
* docs: fix broken wecom link in Malay README
