ECLAIR AI Companion: AI is only as powerful as the analyzer behind it

AI has quickly become table stakes in static analysis. Across the market, assistants explain findings, prioritize them, and propose fixes. Useful? Certainly. Distinctive? No longer.

The ECLAIR AI Companion starts from a different premise: an AI assistant can only exploit capabilities the underlying analyzer actually has. Give it shallow evidence or coarse controls and even the best model soon reaches a ceiling. Give it ECLAIR and long-standing strengths become accessible at an entirely new scale.

MCP (Model Context Protocol) is how it connects. The advantage is what it can reach.

One Companion, two ways to work

ECLAIR AI Companion is included with ECLAIR at no additional ECLAIR licence fee. It brings ECLAIR manuals, product knowledge, configuration guidance, and engineering workflows into compatible AI clients. Engineers can use it to learn and configure ECLAIR, understand coding rules and findings, formulate reviewable deviations, and work through possible corrections using the context available in their workflow.

ECLAIR AI Companion Pro is the annual add-on for teams that want a more direct report-grounded workflow. It includes everything in ECLAIR AI Companion and adds richer ECLAIR report context retrieved directly for the task. This reduces manual context gathering and makes detailed investigations, deviation work, and correction workflows more focused.

The distinction is not between useful and unusable AI integration. Both options put ECLAIR knowledge to work. Pro changes how directly and efficiently a connected assistant can obtain the detailed report evidence it needs.

From expert-only power to an everyday workflow

Applying MISRA C or MISRA C++ to an existing codebase is not a matter of blindly fixing every finding. Some findings expose genuine defects. Others concern intentional constructs that need a justified deviation. Recurring project patterns may require carefully scoped configuration. Tailoring is not optional; it is what makes rigorous compliance work possible without damaging working code.

ECLAIR has always provided exceptionally powerful deviation mechanisms. Each deviation can be defined with surgical precision, drawing on the rich syntactic, semantic, and contextual information ECLAIR derives from the code and its analysis. It can preserve the finding, attach a meaningful classification and rationale, and remain reviewable instead of merely making a counter go down.

That power used to have one practical drawback: only a small community of power users ventured deeply enough into the ECLAIR User’s Manual to master it. Our extensive experimentation shows that modern AI is remarkably good at closing this gap.

With ECLAIR AI Companion, a compatible assistant can consult the manual and relevant project documents, help develop configuration matchers, and support deviation and remediation work using the context available in the workflow. With Companion Pro, it can also retrieve richer ECLAIR report evidence directly, reducing the amount of context the engineer must assemble manually.

This distinction matters. AI cannot invent precision that the underlying analyzer does not possess. With a less expressive tool, a better model may write a better explanation, but it cannot deliver equally precise tailoring. This is the kind of capability we applied to demanding existing-code initiatives involving the Xen Hypervisor and the Zephyr RTOS, as described in Bringing Existing Code into MISRA Compliance: Challenges and Solutions.

Companion Pro: reports made for evidence-based reasoning

ECLAIR is also known for the thoroughness of its reports. They can show source code both before and after preprocessing, identify the code areas contributing to a finding, and preserve macro-expansion and file inclusion chains. Those reports were designed for serious engineering review. They also turn out to be ideal grounding for AI.

ECLAIR AI Companion supports report-driven work using the ECLAIR knowledge and analysis context available in the workflow. ECLAIR AI Companion Pro adds a more direct path: it lets a connected assistant retrieve richer, focused report evidence from ECLAIR for the finding under investigation.

The assistant can explain a violation, distinguish different causes behind similar findings, prepare a narrowly scoped deviation, or propose a source change. Where the connected client has the necessary capabilities and permissions, it can also implement an approved modification and rerun ECLAIR. Better evidence leads to better AI-assisted work.

Companion Pro: depth without token waste

ECLAIR AI Companion is designed to connect ECLAIR to MCP-capable AI products and clients without prescribing one model or interface. The Companion family uses progressive, bounded retrieval: the assistant starts with statistics and grouped counts, retrieves compact summaries, and requests further context only for the findings that matter.

With Companion Pro, this approach extends to detailed report evidence, source excerpts, and relevant documentation. Even very large analyses remain navigable without pouring the entire report into the model’s context. Pro is designed to reduce manual context gathering and token use in detailed report investigations. Actual token use varies by project, task, AI client, model, and supplied context.

About 200% higher productivity in BUGSENG internal experiments

Across deviation formulation, proposed source changes, and implementation, BUGSENG experienced about 200% higher productivity with ECLAIR AI Companion Pro in repeated internal experiments: roughly three times the output for the same effort.

This is not a theoretical projection based on a generic AI benchmark. It is the gain we experienced while applying report-grounded ECLAIR AI Companion Pro workflows to engineering work of the kind our users perform.

The increase comes from shortening the path between a finding and a well-informed next action: less time locating evidence, consulting documentation, constructing precise configuration expressions, drafting changes, and repeating routine steps.

Results vary by project, task, model, and client. The engineer remains responsible for every decision, approval, and validation, but far more of ECLAIR’s power is now accessible in everyday work.

Availability

ECLAIR AI Companion is included with ECLAIR at no additional ECLAIR licence fee.

ECLAIR AI Companion Pro is available only as an annual add-on. With annual-term ECLAIR licences, Pro is aligned with and cannot extend beyond the underlying licence term. With indefinite-term ECLAIR licences, Pro requires current ECLAIR maintenance and is purchased and renewed with the applicable maintenance term. Maintenance may be renewed without Pro; Pro cannot be renewed without the associated maintenance.

If Pro is not renewed, ECLAIR AI Companion continues with its included capabilities.

Charges for third-party AI clients, models, services, and token use are separate and are not included in the ECLAIR licence.

The breakthrough is not an AI layer on top of ECLAIR

The breakthrough is that ECLAIR already has more underneath, and AI can finally make that power routine. ECLAIR AI Companion makes ECLAIR knowledge more accessible to every user. ECLAIR AI Companion Pro makes detailed report-grounded workflows more direct.

The engineer remains in control. ECLAIR remains the source of analysis evidence. The connected AI assistant helps engineers navigate that evidence, formulate options, and carry out approved work.

And the best is still to come.
