* fix: compaction config for small context windows (≤32K)
Raise COMPACTION_SMALL_CONTEXT_WINDOW from 16K to 32K so models like
Haiku 4.5 (30K context) use proportional 50% reserve instead of the
fixed 20K reserve. Also scale fixedOverhead for small contexts (capped
at 40% of context window) to prevent the doom loop where overhead alone
triggers compaction on every step.

* docs: add compaction tuning guidance to limits constants
Explain the relationship between SMALL_CONTEXT_WINDOW and
FIXED_OVERHEAD so devs know the 24K minimum constraint when
tweaking these values.

* feat: add 2-stage pruning to compaction pipeline before LLM summarization
Add two new lightweight stages to the compaction prepareStep pipeline that
recover context tokens cheaply before falling back to expensive LLM
summarization:
- Stage 2: Use AI SDK's pruneMessages to remove old tool call/result
pairs beyond the last 6 messages entirely
- Stage 3: Replace remaining tool output values with short placeholders
("[Cleared — N chars]") while preserving tool call structure and IDs
Both stages re-estimate tokens from message content (not stale step
usage) after modifying messages. The existing LLM summarization and
sliding window fallback remain as Stage 4.
Also adds estimateTokensForThreshold() helper, clearToolOutputs()
function, and COMPACTION_PRUNE_KEEP_RECENT_MESSAGES /
COMPACTION_CLEAR_OUTPUT_MIN_CHARS constants.

* fix: reorder compaction pipeline — truncate before clear, protect recent tools
- Stage 0: Check threshold, return untouched when under (no data loss)
- Stage 1: Prune old tool call/result pairs beyond last 6 messages
- Stage 2: Truncate large tool outputs to 15K chars (keeps partial content)
- Stage 3: Clear old tool outputs with placeholders, protect last 2
- Stage 4: LLM-based compaction with sliding window fallback
clearToolOutputs now accepts keepRecentCount parameter (default 2) to
skip the N most recent tool messages from clearing.

* fix: limits fixes
* fix: address review — preserve toKeep context, derive test values from constants
- When Stage 3 (clearToolOutputs) doesn't resolve overflow, pass
truncated (not cleared) messages to Stage 4 so toKeep retains
meaningful tool outputs for the agent's immediate context
- Add comment explaining intentional conservatism in post-prune
token estimation (step usage is stale, must re-estimate safely)
- Refactor computeConfig tests to derive expected values from
AGENT_LIMITS constants instead of hardcoding magic numbers

* fix: return 500 for server errors in PUT/DELETE skill routes
Previously both handlers returned 404 for all errors, masking filesystem
failures (disk full, permission denied) as "not found". Now only
"not found" errors return 404; everything else returns 500.
* fix: align SKILL.md format with agentskills.io spec
- Move `enabled` and `version` into `metadata` field (spec only allows
name, description, license, compatibility, metadata, allowed-tools)
- Frontmatter `name` now matches directory name (lowercase kebab-case)
- Human-readable name stored in `metadata.display-name`
- Add index signature to SkillMetadata for arbitrary string keys
- Validate frontmatter with type guard in getSkill (remove unsafe cast)
- updateSkill now preserves existing frontmatter fields (license, etc.)
- Tighten buildSkillMd param from Record<string, unknown> to SkillFrontmatter

- truncateToolOutputs: handle all output.type variants (text, json,
content) by checking output.value directly instead of branching on
type. The old code missed type 'content' (array of content parts),
causing 1M+ char tool results to pass through untouched.
- estimateTokens: change chars/4 to chars/3 — HTML/Markdown content
tokenizes at ~3.14 chars/token empirically, not 4.
- COMPACTION_FIXED_OVERHEAD: 5K → 12K to account for system prompt
(~2.5K tokens) + tool definitions as JSON Schema (~8-9K tokens).
- Apply truncateToolOutputs in prepareStep (Stage 0) before token
estimation, not just during summarization.
* fix: support artifact-extracted directory structure in OTA binary discovery
The download_resources system now extracts server binaries into
platform-specific subdirectories (e.g., darwin-arm64/resources/bin/),
but the OTA module only looked for flat binary names. This adds
find_server_binary() which checks both layouts, keeping backward
compatibility with --binaries while supporting the new structure.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* feat: download server binaries from R2 instead of requiring --binaries
Remove the --binaries flag from `ota server release`. The module now
downloads artifact zips from artifacts/server/latest/ in R2, extracts
them, then signs and packages as before. This eliminates the need to
have mono build output locally.

The app icon was oversized in the macOS Dock because the source icon
filled the entire 1024x1024 canvas with no padding. Apple's macOS Big
Sur+ HIG requires ~100px padding on each side (artwork at 824x824
within 1024x1024 canvas). Resized the source icon and regenerated all
platform icons.

* feat: integrate models.dev registry for auto-populated model defaults
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix: fall back to upstream provider for model registry lookup
When the browseros meta-provider is used, the registry lookup now
also tries the upstream provider (e.g., openrouter, anthropic) so
that BrowserOS-hosted models get correct context window and image
support defaults.

* fix: add Object.hasOwn guards to prevent prototype chain lookup
Addresses Greptile review: bracket notation on the registry object
could return prototype-chain properties for keys like __proto__ or
constructor, bypassing the 404 guard in the route handler.
