What it does
The plugin adds procedures to Claude Code that raise work discipline rather than model capability. A per-task router turns on the matching pack: verification of render artifacts, where the agent runs and inspects the output before completion; an evidence gate for multi-part tasks, where work is decomposed into steps and is not marked done without proof; and an investigation protocol for debugging through reproduction, competing hypotheses and a causal chain. A separate hook catches promises to do something without actually doing it. The author shipped only the techniques whose effect he measured in a model comparison, and states plainly that the plugin does not raise the capability ceiling and, at the limit, advises escalating to a stronger model or a human.
Who it is for. For developers who want the Claude Code agent to abandon tasks less often and verify its own output.
Good fit when
- The agent often reports completion without actually verifying the result
- You need a strict bug investigation: reproduce, hypotheses, causal chain
- A task has several parts and no step should be skipped
Not a fit when
- The task hits the model capability ceiling, where procedure does not help
- You need a quick one-off answer without extra checks and hooks
Example request
Build this HTML page and see it through: run it, verify the rendering and show evidence that it worksLimitations
The plugin does not raise model capability: open-ended creativity and self-driven reasoning depth are out of reach, which is a model choice, not a harness one. The effect numbers come from a small self-measurement within a single Claude family; the author calls the direction solid but not the exact figures. The early-stop hook can misfire on a declarative offer such as "I'll write the report if you want"; phrasing offers as questions avoids it. Some features require the always-on mode installed via the setup.sh script.
How to disable. Run bash ${CLAUDE_PLUGIN_ROOT}/setup/uninstall.sh to remove the always-on mode, then uninstall the plugin via /plugin.
FAQ
Does the plugin make the model smarter?
No. It adds procedures for finishing work and verifying results, but does not change the model's capability ceiling. At the limit it advises escalating to a stronger model or a human.
How is the right set of checks turned on?
A per-task router picks the pack itself: render verification for artifacts, an evidence gate for multi-part tasks, an investigation protocol for debugging.

README in short
The README explains the plugin's origin: the author compared the Fable 5 model and Opus 4.8 and kept only the work techniques whose effect was confirmed and transferable through a harness. The plugin includes render-artifact verification, an evidence gate for multi-part tasks via goals.py, an investigation protocol and a deterministic early-stop hook, plus a router that turns on the matching pack per task. Ideas with unconfirmed effect, such as style mimicry or broad reasoning injection, were deliberately left out. Installation goes through the plugin marketplace, with setup.sh for always-on mode and uninstall.sh for removal. MIT license.
