It does not install this agent by itself. - This review did not execute the resource. - The plugin README says the skill runs in full-auto mode, ignores a supplied mode, and applies annotations without approval gates. This file does not add an approval step. - Listed tools include Edit. The comments-only limit is an instruction. This review did not test whether a host can stop a non-comment edit. - It points at dimension-algebra.md for the algebra rules. That reference was not opened. - The dimensional-analysis README has no single-line install command for this plugin alone. 02 / THE REVIEW RECORD ## What we actually inspected. Source review has boundaries. A clear record is more useful than a “safe” badge. ### Material inspected - plugins/dimensional-analysis/agents/dimension-propagator.md - plugins/dimensional-analysis/README.md - README.md - LICENSE ### Our findings - It must process every assigned file and return propagated, reviewed with no propagation changes, or blocked with a reason. It says not to skip silently. - It says to add comments only and never modify executable code, including not fixing a bug it notices while propagating. - It says not to change arithmetic, function logic, control flow, or variable assignments, and not to add or remove scaling. - It says never to overwrite an existing step-2 annotation. A conflicting inference is reported as a mismatch and the existing annotation is left in place. - Its mismatch scale includes a missing or wrongly directed scaling factor and inconsistent return paths. Those are reports. It calls the later validator the full check and does not claim to be that pass. ### Not established by this review - The resource was not executed and its tools were not called. - No source file was annotated. - dimension-algebra.md and the dimensional-analysis skill were not opened. The review applies to the material and revision named here. A newer upstream release can change its behavior. 03 / PUT IT TO WORK ## Use the role in your project. [Upstream setup instructions ↗](https://github.com/trailofbits/skills/blob/8e54050ae63c2f62224c35b1616efe71865b4777/README.md) DOCUMENTED COMMAND /plugin marketplace add trailofbits/skills Copy command ↗ Copying does not execute this command. It may retrieve a newer version than the reviewed source. - The repository README at this pin shows /plugin marketplace add trailofbits/skills as one unindented line. That line adds the marketplace, not this agent. - The dimensional-analysis README names dimension-propagator as the propagation step. It shows no install line. - The same root README shows /plugin menu for browsing plugins. It does not name this file. ### Before you start - Claude Code, which is the host the marketplace README documents - A dispatch that supplies the units file, the assigned paths, and the earlier anchor annotations this file says it expects ### Compatibility Claude Code ### Comment edits on assigned source files - Listed tools include Read, Grep, Glob, and Edit, plus TodoRead, TodoWrite, and List. - The body says to add comments only and not to change executable code or existing anchor annotations. - The plugin README says the workflow applies annotations without an approval gate. This file does not add one. ### Cost model CC-BY-SA-4.0 with attribution and share-alike. No fee is stated for this file, and the agent was not run. 04 / FOLLOW THE EVIDENCE ## The source trail.
