The model reads a PNG/JPEG/WebP/GIF file, the bytes commit through the durable attachment lifecycle, and the tool result carries the real ImageBlock so the image enters context from the next request onward. FileSystem gains a bounded readBytes primitive (local + E2B providers); registration is conditional on the attachment store, and a strict execution gate refuses routes that do not declare image input, so a text route's durable history stays free of image blocks. llm-replay models may declare inputModalities, letting keyless ACP snapshots pin both the sha256-referenced success and the verbatim refusal. Supersedes the withdrawn route-scoped design of PR #598; the decision record is .agents/notes/implemented/feature/2026-08-10-minimal-read-image-tool.md.
skill/ — skill capability family
English | 中文
This family discovers reusable agent instructions and exposes them to the model through a provider-neutral catalog and loader.
| Package | Role | ctx key |
|---|---|---|
skill/ |
Defines skill provider registration and lookup | ctx.skills |
skill-badge/ |
Contributes the optional bundled dsh badge skill | registers on ctx.skills |
skill-local/ |
Discovers skills from local filesystems | registers on ctx.skills |
tool-skill/ |
Publishes the skill catalog and model-facing loader | registers on ctx.tools |
This capability remains outside the core control spine and can use local, embedded, or remote providers without changing the model-facing contract.
The subsystem reference — discovery priority, catalog snapshots, the skill loader — is docs/subsystems/skills.md.
