      "message": "loop: do slug generation outside the agent loop\n\n[This commit message written entirely by a human; it is all useful.]\n\nWe can make a slug based on the first message.\nIt\u0027s good enough.\nThat keeps it--and the slug tool--out of the agent\u0027s context.\nIt\u0027s also one fewer step for extremely short Sketch runs,\nwhich is the straw that broke this particular camel\u0027s back.\n\nThis is a mild UI regression, in that there\u0027s a slight stall\nafter the user types their first message, during which\nthe slug is being generated. See (2) below.\n\nWhile we\u0027re here, add handling of compaction agent messages.\n\nThis leaves two big TODOs outstanding:\n\n1.\n\nUntangle the awful rats nest that is slug and branch management;\nwe have callbacks back and forth and layers and locking and it\u0027s all confusing.\nOne visible for that this ugliness takes is that every time the agent tries out a slug,\nthe top bar in the webui updates, even if we then reject that slug as a duplicate.\nthere are other forms of ugliness, just less visible.\n\n2.\n\nMake slug generation concurrent with the rest of the agent,\nto avoid a short stall right after the user\u0027s first request (ick).\n\nWhen we make slug setting concurrent, we\u0027ll likely need to resuscitate\nthe bashPermissionCheck, except it\u0027ll be \"silently block and wait for\nbackground slug generation to complete\", rather than \"reject the tool call\".\nDitto for about_sketch, and any other tool call that expects\nthe slug or branch name to be set.\n\nGenerally, before undertaking this effort, we should fix (1) above,\nmake convos generally concurrency safe (maybe COW?), and\nfigure out to get race-enabled innie builds.\n\nCo-Authored-By: sketch \u003chello@sketch.dev\u003e\nChange-ID: s8ac5f6a9faa611ebk\n"

      "message": "budget: remove num-iterations and wall clock time limits\n\nRemove iteration count and time-based budget limits from the agent budget system\nwhile preserving the budget concept for dollar-based limits only.\n\nProblem Analysis:\nThe budget system previously supported three types of limits:\n1. MaxResponses (iteration count limit)\n2. MaxWallTime (wall clock time limit)\n3. MaxDollars (cost limit)\n\nThis created complexity in both implementation and user experience, with\nmultiple overlapping budget mechanisms that could trigger independently.\nThe iteration and time limits added limited value compared to the more\npractical dollar-based budget control.\n\nImplementation Changes:\n\n1. Budget Structure Simplification:\n   - Remove MaxResponses and MaxWallTime fields from Budget struct\n   - Keep only MaxDollars field for cost-based budget control\n   - Simplify Budget to single-field struct with clear purpose\n\n2. CLI Flag Removal:\n   - Remove -max-iterations flag from command line interface\n   - Remove -max-wall-time flag from command line interface\n   - Keep -max-dollars flag with same functionality\n   - Remove unused time import from cmd/sketch/main.go\n\n3. Budget Logic Streamlining:\n   - Simplify ResetBudget() to only adjust MaxDollars based on usage\n   - Simplify overBudget() to only check dollar limits\n   - Remove iteration and time checking logic throughout\n\n4. Container Configuration Updates:\n   - Remove MaxIterations and MaxWallTime from ContainerConfig struct\n   - Remove corresponding docker command arguments\n   - Maintain MaxDollars configuration and passing\n\n5. UI Cleanup:\n   - Remove budget display of max responses and max wall time from termui\n   - Keep dollar-based budget information display\n\n6. Test Updates:\n   - Update test Budget initialization to use only MaxDollars\n   - Verify all existing tests continue to pass\n\nTechnical Details:\n- Budget struct now contains only MaxDollars float64 field\n- ResetBudget adjusts budget by adding current TotalCostUSD to MaxDollars\n- overBudget checks only dollar spending against MaxDollars limit\n- CLI help shows only -max-dollars option, no iteration/time options\n- Docker container launch passes only max-dollars parameter\n\nBenefits:\n- Simplified budget system with single, clear cost control mechanism\n- Reduced complexity in budget logic and error handling\n- Cleaner CLI interface with fewer confusing options\n- More predictable budget behavior focused on practical cost limits\n- Easier to understand and configure for users\n\nTesting:\n- All existing tests pass with updated budget structure\n- CLI help verification shows only max-dollars option\n- Build verification confirms no compilation errors\n- Budget functionality preserved for dollar-based limits\n\nThis change streamlines the budget system to focus on practical cost control\nwhile maintaining all existing dollar-based budget functionality and removing\ncomplexity around iteration and time-based limits.\n\nCo-Authored-By: sketch \u003chello@sketch.dev\u003e\nChange-ID: sa7be127e12d43ee7k\n"

If originalBranch\nwas already \"foo1\", this created \"foo11\", \"foo12\", etc. instead of the\nintended incremental sequence.\n\nImplementation improvements:\n\n1.

Enhanced retry logic:\n   - Uses parsed base name and starting number for proper incrementing\n   - Formula: fmt.Sprintf(\"%s%d\", baseBranch, startNum+retries)\n   - Ensures consistent incremental naming regardless of starting branch name\n   - Maintains 10-retry limit for robustness\n\n3. Comprehensive test coverage:\n   - TestBranchNamingIncrement covers multiple scenarios with table-driven tests\n   - TestParseBranchNameAndNumber validates parsing logic with edge cases\n   - Tests verify proper behavior for branches with and without existing numbers\n   - Edge cases include numbers in middle vs end of branch names\n\nTechnical details:\n- parseBranchNameAndNumber() scans from end of string backward for consecutive digits\n- Only trailing digit sequences are treated as numerical suffixes\n- Error handling ensures malformed numbers default to treating branch as having no suffix\n- Maintains existing user notification when branch gets renamed\n\nExamples of corrected behavior:\n- \"foo\" -\u003e \"foo\", \"foo1\", \"foo2\", \"foo3\"\n- \"foo1\" -\u003e \"foo1\", \"foo2\", \"foo3\", \"foo4\"\n- \"foo42\" -\u003e \"foo42\", \"foo43\", \"foo44\", \"foo45\"\n\nThis resolves the reported issue where branches were getting names like\nfoo1, foo11, foo111 instead of proper incremental numbering.\n\nCo-Authored-By: sketch \u003chello@sketch.dev\u003e\nChange-ID: sfba5fdcdaf99fdcdk\n\nloop: simplify parseBranchNameAndNumber with regex\n\nReplace verbose manual parsing logic with a clean regular expression\napproach to extract trailing digits from branch names.\n\nChanges:\n- Replace 20+ lines of manual digit scanning with simple regex: ^(.+?)(\\d+)$\n- Add regexp import to support the regex functionality\n- Maintain exact same behavior and test coverage\n- Cleaner, more readable, and less error-prone implementation\n\nThe regex ^(.+?)(\\d+)$ captures:\n- Group 1: Everything up to the trailing digits (non-greedy match)\n- Group 2: The trailing digit sequence\n\nThis handles all the same cases but with much simpler code.\n\nCo-Authored-By: sketch \u003chello@sketch.dev\u003e\nChange-ID: sea27e90c492b83d8k\n"

      "message": "llm and everything: Update ToolResult to use []Content instead of string for multimodal support\n\nThis was a journey. The sketch-generated summary below is acceptable,\nbut I want to tell you about it in my voice too. The goal was to send\nscreenshots to Claude, so that it could... look at them. Currently\nthe take screenshot and read screenshot tools are different, and they\u0027ll\nneed to be renamed/prompt-engineered a bit, but that\u0027s all fine.\n\nThe miserable part was that we had to change the return value\nof tool from string to Content[], and this crosses several layers:\n - llm.Tool\n - llm.Content\n - ant.Content \u0026 openai and gemini friends\n - AgentMessage [we left this alone]\n\nExtra fun is that Claude\u0027s API for sending images has nested Content\nfields, and empty string and missing needs to be distinguished for the\nText field (because lots of shell commands return the empty string!).\n\nFor the UI, I made us transform the results into a string, dropping\nimages. This would have been yet more churn for not much obvious\nbenefit. Plus, it was going to break skaband\u0027s compatibility, and ...\nyet more work.\n\nOpenAI and Gemini don\u0027t obviously support images in this same way,\nso they just don\u0027t get the tools.\n\n~~~~~~~~~~ Sketch said:\n\nThis architectural change transforms tool results from plain strings to []Content arrays, enabling multimodal interaction in the system. Key changes include:\n\n- Core structural changes:\n  - Modified ToolResult type from string to []Content across all packages\n  - Added MediaType field to Content struct for MIME type support\n  - Created TextContent and ImageContent helper functions\n  - Updated all tool.Run implementations to return []Content\n\n- Image handling:\n  - Implemented base64 image support in Anthropic adapter\n  - Added proper media type detection and content formatting\n  - Created browser_read_image tool for displaying screenshots\n  - Updated browser_screenshot to provide usable image paths\n\n- Adapter improvements:\n  - Updated all LLM adapters (ANT, OAI, GEM) to handle content arrays\n  - Added specialized image content handling in the Anthropic adapter\n  - Ensured proper JSON serialization/deserialization for all content types\n  - Improved test coverage for content arrays\n\n- UI enhancements:\n  - Added omitempty tags to reduce JSON response size\n  - Updated TypeScript types to handle array content\n  - Made field naming consistent (tool_error vs is_error)\n  - Preserved backward compatibility for existing consumers\n\nCo-Authored-By: sketch \u003chello@sketch.dev\u003e\nChange-ID: s1a2b3c4d5e6f7g8h\n"
