Fullbleed 2.5.2 ? clearer MCP tool guidance

Fullbleed 2.5.2 gives document agents clearer MCP inputs and more accurate side-effect hints. Every input now describes how to use it, including source selection, workspace paths, preview resolution, asset actions, compiled bindings, handle reuse, and explicit verification checks.

These descriptions come from the shared runtime contract used by both MCP entrypoints. This patch preserves validation constraints and rendering behavior, adds no core runtime dependencies, and keeps the optional MCP adapter at 0.1.1.

Upgrade the engine in the Python environment used by your MCP client, then restart that client:

python -m pip install --upgrade fullbleed fullbleed-mcp

See the agent setup guide for MCP configuration and the pinned Agent Skill installation command.

Validation includes 451 Python tests, 15 ABI3 wheel builds, 19 installed-wheel checks, the official MCP client SDK, all eleven tools, and fresh public package installation. Nine PDF fixtures and two PNG fixtures are byte-identical to the tested 2.5.1 baseline. The attached verification report and engineering evidence retain the checks and their scope. Profile and parser checks do not establish independent ISO PDF/VT certification.

Distributions, the matching Rust crate, generated agent artifacts, checksums, and verification evidence are attached. Fullbleed remains MIT-licensed and free for commercial use.
