CARBON Lite

CARBON Lite

By testers.ai

CARBON Lite helps developers and QA engineers test software inside their coding agent. Jay, an AI test manager, guides eight bounded workflows: broad assessment, focused feature testing, issue hunting, accessibility, current-run evidence maps, disposable demos, help, and preferences. Talk directly to Jay with /jay or /j. Includes a portable visual Studio report with evidence-backed findings, coverage gaps, and confidence assessments. Uses the coding agent's authorized browser and terminal tools; reports distinguish executed checks from proposed work. Test coverage depends on the available project context, access, and execution tools. No MCP server, OAuth, telemetry, or hosted account. Open source under the MIT license. Not a certification or guarantee that software is defect-free.

Fiera Incrementality

Fiera Incrementality

By Fiera

Measure whether your ads drive results that would not have happened anyway. Fiera Incrementality helps paid media teams choose the right test, design it, and read it: - Planner: turns a question (is brand search incremental? should we cut Meta prospecting?) into a test plan. Recommends the platform's own lift study when one is available, a geo experiment when channels must be compared on business data, and a switchback or a directional before/after read when nothing else is possible. - Geo test design: from a CSV of KPI by region and day, picks treated regions by stratified randomization, estimates the minimum detectable effect on held-out history, the test length and the cost, and writes a plan to approve before launch. - Geo test readout: estimates the effect with two methods (time-based regression and synthetic control), intervals from placebo tests, incremental CPA and ROAS, and robustness checks. - Quick incrementality: a directional read on a pause or budget change, compared with several baselines and their normal noise, plus switchback analysis for single markets. - Lift result review: an independent check of a lift study, vendor test or internal claim. Results feed attribution (incrementality factors) and marketing mix models (Meridian, Robyn, PyMC-Marketing) as calibration. Methods follow the published work behind Google's TBR and Meridian GeoX, Meta's GeoLift and the synthetic control literature, with sources cited in the skills. The analysis runs in a bundled Python script on the data you upload. It is calibrated on simulated panels: false positive rate in A/A tests, coverage of the true effect, and power at the predicted detectable effect. Intended for performance marketing, growth and analytics teams. Limits: results are as good as the KPI data you provide; directional methods are labeled as such and do not prove causation; platform lift studies are run in the ad platform, not by this plugin.

No BS PPC by Fiera

No BS PPC by Fiera

By Fiera

Answers to Google Ads questions the way a senior paid search manager gives them: the verdict first, the numbers that decide it, the next action, and what would change the answer. No generic checklists. - No BS PPC: bidding, budgets, keywords, match types, negatives, Performance Max, AI Max, Demand Gen, ad copy and tracking. Corrects common mistakes (Ad Strength as a KPI, bid adjustments under Smart Bidding, scaling brand, reading immature conversions) with the reason and the number. - Performance triage: from a campaign report with a date segment, splits a change in CPA or conversions into demand, impression share, CTR, CPC and conversion rate, by segment (brand, non-brand, PMax, app, upper funnel), and separates mix shift from real change. - Search terms cleanup: n-gram analysis of a search terms report, negative keyword candidates that do not block converting traffic, and routing decisions for competitor, geo and brand terms. - Account quick audit: measurement, bidding, structure, queries, ads and efficiency in order of money at stake, with evidence for each finding. - RSA review: writes and checks responsive search ads against character limits and the editorial rules that cause disapprovals. - Bid targets: target CPA or ROAS from margin, lifetime value and funnel rates, not from last quarter's results. - Budget pacing: month-to-date spend, forecast and the daily spend needed to land on budget. - Auction insights: who gained share, who is new, who ranks above you. - Change history review: target changes inside the calibration window, large swings, auto-applied recommendations, and which change lines up with a performance shift. - Quality Score review: spend-weighted score and the component that costs the most. Platform facts (limits, dates, policies) are checked against Google's help pages and cited. Report exports in English and Spanish are read directly, including the interface's preamble and totals rows. Built by Fiera, a paid media agency, from the rules it applies to the accounts it manages. Intended for in-house paid search teams, agencies and founders who run their own ads. Limits: the plugin does not connect to or change your Google Ads account; it works from what you share.

Uptick Workspace Audit

Uptick Workspace Audit

By Uptick Systems

Find practical improvements in how you or your team work with AI. Uptick inspects the workspace evidence you make available, including agent instructions, skills, workflows, documentation, and verification steps. Get ranked opportunities with supporting evidence and confidence levels, proposed instruction changes, a seven-day action plan, and ways to measure progress. The audit is read-only: it does not edit files or send workspace contents to Uptick. It needs access to relevant workspace material through your AI tool. Limited evidence produces a limited audit, and recommendations do not guarantee savings or business results.

ui-consistency

ui-consistency

By Kamen Kurtev

ui-consistency makes your project's own design system something the coding agent reads before it writes UI. Ask for a page, a form or a change to one, and the agent first reads how the pages you already have are built: which shared components they use and how, the theme and its tokens, how they validate input and show errors. Then it writes the new page the same way, from a checklist, and has a separate agent compare the result with the page it follows. It works with any UI technology, including plain HTML and CSS, in a single app or a monorepo, and needs no configuration. It reads only your project; it has no server, no network access and no telemetry, and writes nothing into your repository besides the pages you asked for. It needs a project with code to read: in a conversation without one there is nothing for it to follow.
