Changes ImageAnalysisConfig from providers array to provider_models
mapping for granular vision model control per CLIProxy provider.
Breaking change: config.yaml image_analysis section now uses
provider_models instead of providers/model fields.
Provider-to-model mappings:
- agy → gemini-2.5-flash
- gemini → gemini-2.5-flash
- codex → gpt-5.1-codex-mini
- kiro → kiro-claude-haiku-4-5
- ghcp → claude-haiku-4.5
- claude → claude-haiku-4-5-20251001
Hook checks CCS_CURRENT_PROVIDER against provider_models and skips
if no vision model configured for that provider.
Intercept Read tool calls for image/PDF files and route through CLIProxy
with gemini-2.5-flash for vision analysis. Returns text descriptions
instead of blocking, enabling Claude to "see" images via proxy.
Key changes:
- Add image-analyzer-transformer.cjs hook script
- Add ImageAnalysisConfig type and loader
- Add hook installer and profile injector
- Add prompt templates for analysis customization
- Add e2e test suite (excluded from normal CI runs)
- Configure test:e2e script for manual testing
Environment variables:
- CCS_IMAGE_ANALYSIS_ENABLED: Enable/disable (default: 1)
- CCS_IMAGE_ANALYSIS_MODEL: Vision model (default: gemini-2.5-flash)
- CCS_IMAGE_ANALYSIS_TIMEOUT: Timeout in seconds (default: 60)
- CCS_CLIPROXY_API_KEY: API key for CLIProxy auth
- CCS_CLIPROXY_PORT: CLIProxy port (default: 8317)
Closes#426
Match WebSearch hook pattern:
- ENABLED by default for settings/cliproxy profiles
- DISABLED for native Claude accounts (account/default)
- User can override via config: hooks.block_image_read.enabled: false
This ensures CCS CLI users get context protection out-of-the-box
while native Claude subscription users are unaffected.
Add PreToolUse hook that intercepts Read tool calls on image files
(.png, .jpg, .webp, etc.) and blocks them with helpful message.
This prevents context exhaustion when image generation skills
produce multiple files and the agent tries to read them (each
image can consume 100K+ tokens).
Configuration:
- Enable via config.yaml: hooks.block_image_read.enabled: true
- Or env var: CCS_BLOCK_IMAGE_READ=1
Hook integration:
- lib/hooks/block-image-read.cjs - the hook script
- src/utils/hooks/image-read-block-hook-env.ts - config loader
- Integrated into all spawn locations (ccs.ts, shell-executor,
cliproxy-executor)
Closes#426
