### [Your agent can't fix what it can't see](https://yomu.fyi/post/your-agent-can-t-fix-what-it-can-t-see.md)

Coding agents frequently fail to resolve production bugs when restricted to source code alone, as they lack critical runtime context such as stack traces, breadcrumbs, and environment data. To bridge this gap, Sentry introduces Sentry MCP and the Sentry CLI to supply agents and developers with structured production telemetry. The Model Context Protocol integration supports clients like Claude Code, Cursor, and VS Code, while the CLI enables scripted workflows. When an alert triggers, an agent uses trace and commit metadata to diagnose root causes across service boundaries, generate regression tests, and open draft pull requests. Over six months, the Autofix pull request merge rate increased from 41% to 46%.


### [What it feels like building with Stripe Projects](https://yomu.fyi/post/what-it-feels-like-building-with-stripe-projects.md)

The post recounts a 60-minute attempt to build a GitHub traffic dashboard with Stripe Projects, motivated by GitHub’s 14-day limit on traffic history. Using Cursor’s agentic chat workflow alongside Projects, the builder assembled a Next.js application with Auth0 authentication, Supabase persistence, Prisma schema management, Vercel hosting, scheduled jobs, environment wiring, and periodic GitHub traffic synchronization. The experiment largely avoided direct coding and instead tested whether AI-mediated orchestration could produce a production-shaped stack quickly. As services and credentials appeared across providers, the main difficulty shifted from implementation to understanding ownership, deployment topology, environment management, and operational flow. The repositories synced, charts populated, and historical data appeared, while the experience also exposed a need for clearer generated architecture or infrastructure-as-code descriptions of the assembled system.


### [AI as the Next Abstraction Layer: How I see engineering evolving at Thumbtack](https://yomu.fyi/post/ai-as-the-next-abstraction-layer-how-i-see-engineering-evolving-at-thu.md)
- Company: [Thumbtack](https://yomu.fyi/company/thumbtack.md)
- Author: Ananda Kanagaraj Sankar
- Published: May 22, 2026
- Type: Explainer

Thumbtack is transitioning its engineering workflow from ad-hoc tool experimentation to end-to-end agentic software development. Unlike previous deterministic abstractions such as compilers or high-level languages, artificial intelligence introduces non-determinism where identical prompts can produce varying code and trade-offs. Because consumer marketplace experiments still require weeks for behavioral signals to stabilize, accelerated implementation primarily helps teams prepare cleaner experiment designs and parallelize hypotheses within experimentation bandwidth constraints. Consequently, day-to-day engineering responsibilities shift upstream from manual coding toward problem framing, system architecture, validation, and co-designing features with product managers. Teams maintain technical sharpness by rigorously reviewing generated code while accepting that long-term specialization above the abstraction layer will become standard across the organization.


### [Introducing Nova, our internal platform for coding agents](https://yomu.fyi/post/introducing-nova-our-internal-platform-for-coding-agents.md)

- Author: Ilya Yakovlev,Andrew Cheung,Binoy Dash,Simran Jumani,Dmitriy Meyerzon,Mark Breitenbach,Ishan Mishra,Kazuaki Okumura,Mike White,Kevin Altschuler
- Published: May 21, 2026

Dropbox developed Nova, an internal platform that runs AI coding agents in isolated cloud environments integrated with their Bazel monorepo. The platform supports both interactive developer workflows and autonomous background tasks, such as automated CI debugging, flaky test remediation, and codebase-wide migrations. By pairing code generation with automated validation and strict execution guardrails, Nova ensures generated fixes are tested and reproducible.


### [The product analytics you already have](https://yomu.fyi/post/the-product-analytics-you-already-have.md)

Software engineers frequently rely on separate product analytics tools and teams to answer user behavior questions, creating disjointed data models and delayed insights. Existing debugging telemetry within tools like Sentry—specifically spans, structured logs, and application metrics—can serve as the primary source for product metrics. Developers enrich request spans with business-level attributes, record discrete business events through wide structured logs, and track KPIs with metric counters and distributions. This unified telemetry links business outcomes directly to underlying traces, errors, releases, and source code lines, enabling immediate root-cause analysis and automated alerts. While multi-session cohort and funnel aggregation remains a current tooling gap, standard telemetry solves day-to-day adoption, performance, and revenue questions.


### [clickhousectl v0.2.0: Postgres, ClickPipes and more](https://yomu.fyi/post/clickhousectl-v0-2-0-postgres-clickpipes-and-more.md)
- Company: [Clickhouse](https://yomu.fyi/company/clickhouse.md)
- Author: Al Brown
- Published: May 20, 2026
- Type: Announcement

clickhousectl v0.2.0 expands the beta CLI with local and ClickHouse Cloud managed Postgres, ClickPipes, SQL over HTTP for Cloud services, agent-oriented output changes, and a standalone Rust client for the ClickHouse Cloud API. Local Postgres runs in Docker, is keyed by name and major version, stores isolated data under .clickhouse/servers/-pg/data/, and supports versions 16, 17, and 18. ClickPipes covers batch, streaming, CDC, and snapshot sources including object storage, Kafka-compatible systems, Kinesis, Postgres, MySQL, MongoDB, and BigQuery. Cloud queries use a provisioned or lazily enabled Query Endpoint and service-scoped API key, while the endpoint uses sql\_console\_admin and the key has no organization-level roles. The release also adds Markdown-style tables and credential debugging, with more than 5,000 users reported five weeks into the project.


### [Optimizing Our Build Times by Migrating from Webpack to Rspack](https://yomu.fyi/post/optimizing-our-build-times-by-migrating-from-webpack-to-rspack.md)
- Company: [Yelp](https://yomu.fyi/company/yelp.md)
- Author: Benson Pan, Software Engineer
- Published: May 20, 2026
- Type: Problem & solution

As Yelp's JavaScript monorepo expanded over time, Webpack build speeds became a significant engineering bottleneck. To resolve this without rewriting complex configurations, the team selected Rspack for its direct compatibility with existing Webpack setups and plugins. Yelp implemented an adapter pattern to generate Rspack configurations dynamically from original Webpack files, enabling a staged opt-in rollout across development tools and CI environments. Following the initial migration, engineers addressed performance issues in barrel files using automated codemods to replace star re-exports and import-then-export patterns with named re-exports. Combined with Rspack's portable persistent caching, the migration reduced integration build times by approximately 52 percent and warm cache builds by up to 80 percent.


### [PaddleOCR 3.5: Running OCR and Document Parsing Tasks with a Transformers Backend](https://yomu.fyi/post/paddleocr-3-5-running-ocr-and-document-parsing-tasks-with-a-transforme.md)
- Company: [Hugging Face](https://yomu.fyi/company/hugging-face.md)
- Author: AlexZhang, cuicheng, Jun Zhang, Manhui Lin, Yue Zhang
- Published: May 18, 2026
- Type: Announcement

PaddleOCR 3.5 adds a more flexible inference-engine interface for OCR and document parsing, allowing supported models to run with a Hugging Face Transformers backend selected through engine="transformers". It keeps pipelines managed by PaddleOCR while exposing backend-specific settings such as dtype, device placement, and attention implementation through engine\_config. The release supports command-line and Python usage, with examples configuring GPU execution and float32, bfloat16, or SDPA options according to hardware and deployment environment. This provides a more natural path for RAG, Document AI, search, analytics, and agent stacks centered on PyTorch and Transformers, while the default paddle\_static backend is usually recommended when maximizing OCR or document parsing throughput is the priority.


### [Coding Agent Horror Stories: The Security Crisis Threatening Developer Infrastructure](https://yomu.fyi/post/coding-agent-horror-stories-the-security-crisis-threatening-developer.md)
- Company: [Docker](https://yomu.fyi/company/docker.md)

- Type: Problem & solution

Autonomous AI coding agents increasingly handle developer workflows, but their execution model introduces critical security risks. Operating with the executing user's full permissions, these agents can read ambient secrets, inherit cloud credentials, and run destructive shell commands without human intervention. Documented incidents between October 2024 and February 2026 reveal systemic hazards, including unintentional home directory deletions and increased security vulnerabilities in generated code. To address these vulnerabilities, Docker Sandboxes isolate agent execution within dedicated microVMs, preventing access to the host filesystem and blocking common credential paths by default. Routing changes through Git worktrees and restricting network egress ensures that agent actions remain strictly bounded and reviewable before affecting main branches or production infrastructure.


### [Scaling developer experience: How we improved Android Studio in a large monorepo](https://yomu.fyi/post/scaling-developer-experience-how-we-improved-android-studio-in-a-large.md)
- Company: [Grab](https://yomu.fyi/company/grab.md)
- Author: Rifqi Fahmi
- Published: May 15, 2026
- Type: Problem & solution

Grab’s passenger Android monorepo contains roughly 2,000 modules and 11 million lines of code, making Gradle-based Android Studio syncs increasingly slow and memory-intensive even though Bazel handles builds. A cold full sync could exceed 35 minutes, and a survey of 55 developers found that 82% wanted an option to exclude modules from syncing. The team built a custom Focus plugin that uses a dependency graph generated during migrateToBazel, avoids repeating Gradle’s configuration phase, and integrates with Android Studio through a one-click Select → Focus → Sync flow; a Groovy include-shadow technique avoids requiring teams to reorganize settings files. Typical focused syncs fell below two minutes, while reported results show reductions from 35 minutes to under one minute depending on module size, memory usage from 10 GB to 2 GB, and improved Compose preview updates, with broader IDE operations requiring expanded focus or full sync.


### [From latency to instant: Modernizing GitHub Issues navigation performance](https://yomu.fyi/post/from-latency-to-instant-modernizing-github-issues-navigation-performan.md)
- Company: [Github](https://yomu.fyi/company/github.md)
- Author: Natalie Guevara
- Published: May 14, 2026
- Type: Problem & solution

GitHub Issues addressed navigation latency by shifting workloads to the client using a local-first, stale-while-revalidate architecture. To evaluate perceived delays, the team tracked user transitions through Highest Priority Content thresholds, aiming for instant rendering in under 200 milliseconds. The core implementation added a persistent client-side cache using IndexedDB, paired with a synchronous in-memory tier to serve hot issue payloads without asynchronous overhead. A selective preheating mechanism resolves missing cache entries for high-intent links without overburdening backend capacity with redundant requests. Following broad rollout, the proportion of instant React soft navigations increased from 4% to approximately 22%, yielding an overall cache-hit ratio of around 33%.


### [New ways to agentically build and edit dashboards](https://yomu.fyi/post/new-ways-to-agentically-build-and-edit-dashboards.md)
- Company: [Sentry](https://yomu.fyi/company/sentry.md)
- Author: Ben Coe, Steve Zegalia
- Published: May 14, 2026
- Type: Announcement

Pre-configured monitoring templates often fail to meet organization-specific needs, forcing developers to manually build dashboards widget by widget. Sentry introduced AI-agent-powered dashboard creation and editing in open beta, alongside CLI management tooling and template revisions. Users can prompt an AI chat interface to build or adjust dashboards, duplicate and customize uneditable Sentry-built templates, or execute dashboard commands directly in their terminal. Dashboards leverage issue, tracing, and application metric data across frontend, backend, mobile, and framework-specific views like Next.js and Laravel. Edits made through the UI, CLI, or AI agent are automatically tracked in a revision history that supports one-click rollbacks.


### [You can't whisper at an AI agent](https://yomu.fyi/post/you-can-t-whisper-at-an-ai-agent.md)
- Company: [Stripe](https://yomu.fyi/company/stripe.md)
- Author: James Beswick
- Published: May 14, 2026
- Type: Explainer

Stripe engineers ran roughly a dozen experiments to determine how to get AI agents to use current API versions, follow integration best practices, and load the Stripe skill. Passive hints, including SDK files, AGENTS.md guidance, and API warning responses, were largely ignored, while active prompts and distribution mechanisms performed better. A modular, progressively disclosed skill structure outperformed a monolithic file by roughly 10% and reduced token usage; a CLI login prompt led 30–35% of viewers to copy its install command, and explicit compatibility-mode errors prompted agents to correct version mismatches. The results suggest that agent-facing developer experience is primarily a distribution problem, with hard steering through errors and loaded instructions more reliable than soft hints agents may never encounter.

- Company: [Pinterest](https://yomu.fyi/company/pinterest.md)
- Author: Pinterest Engineering
- Published: May 12, 2026
- Type: Problem & solution

Software engineers deploying AI agents often encounter unreliable skill invocation for repository-specific architectures, such as Pinterest's iOS framework. To quantify and resolve this issue, a Bash test harness piped positive and negative prompts into Pin-agent and Claude Code while parsing streamed JSON logs for execution signatures. Initial vanilla benchmarks yielded baseline accuracies of 73% for GPT 5.2-codex and 62% for Opus 4.5 Claude. Optimizations such as expanding YAML frontmatter descriptions with architectural context, utilizing capitalized imperative directives, and adding reference tables in AGENTS.md raised invocation rates. Both agents reliably loaded skills when prompts contained explicit invocations, demonstrating that empirical testing paired with descriptive prompting stabilizes agent skill adoption.


### [Fighting Tool Sprawl: The Case for AI Tool Registries](https://yomu.fyi/post/fighting-tool-sprawl-the-case-for-ai-tool-registries.md)
- Company: [MongoDB](https://yomu.fyi/company/mongodb.md)
- Author: Peter Richards
- Published: May 11, 2026
- Type: Problem & solution

Rapid enterprise AI agent adoption without centralized infrastructure introduces widespread tool sprawl, duplicated engineering effort, and severe operational opacity. Individual application teams frequently build ad hoc, undocumented integrations, leaving security teams unable to discover, audit, or approve active agent capabilities. Internal enterprise tool registries address this coordination failure by establishing an organization-specific catalog tailored to internal security policies, data, and compliance requirements. A production-grade registry delivers core discovery and version tracking functionality while surfacing security certification metadata and enabling consistent identity-scoped access control across teams. Organizations establishing centralized tool infrastructure can accelerate agent onboarding, implement deny-by-default governance policies, and mitigate technical debt before uncoordinated deployments compound across the enterprise.


### [Beyond efficiency: PayPal expands what's possible to build with AI](https://yomu.fyi/post/beyond-efficiency-paypal-expands-what-s-possible-to-build-with-ai.md)
- Company: [Cursor](https://yomu.fyi/company/cursor.md)
- Author: Cursor
- Published: May 11, 2026
- Type: Explainer

PayPal describes how it used Cursor to accelerate software development across an organization of 8,000 developers and a codebase spanning decades. It began with high-impact teams because the company moves money for more than 400 million customers and mistakes are costly; within two weeks, those teams were deploying daily rather than weekly or biweekly, and adoption spread organically. The company says a Java upgrade across 3,000 applications took two months instead of an estimated eight to twelve, while highly adopting teams saw more frequent deployments, shorter lead times, and lower change failure rates. PayPal continues to measure deployment frequency, lead time, and change failure rate rather than AI-generated code, and Michelle Chance believes the company could deliver 40% more capabilities in 2026 than in 2025.

JavaScript application performance monitoring tools rely on monkey-patching via require-in-the-middle and import-in-the-middle, which breaks with ECMAScript Modules, bundlers, and non-Node runtimes. To solve this, an initiative is replacing monkey-patching with Node's built-in diagnostics\_channel TracingChannel API across server-side JavaScript libraries. Under this pattern, libraries publish structured events while monitoring vendors subscribe to them with zero overhead when unlistened. The author leveraged Claude Code workflows alongside direct maintainer communication to draft proposals, implement code, and manage reviews across 44 target packages. Ten libraries including mysql2, node-redis, ioredis, and unjs modules have merged support, while active efforts continue on shared OpenTelemetry mapper registries and remaining ecosystem packages.


### [Improved debugging for Expo apps with the React Native SDK](https://yomu.fyi/post/improved-debugging-for-expo-apps-with-the-react-native-sdk.md)
- Company: [Sentry](https://yomu.fyi/company/sentry.md)
- Author: Aleksandr Pantiukhov
- Published: May 6, 2026
- Type: Announcement

Expo applications generate approximately 75% of the total event volume received from React Native applications in Sentry. In response, Sentry updated its React Native SDK starting in version 8.10 to improve Expo debugging and performance monitoring workflows. The update automatically enriches events with Expo constants and over-the-air update context, including channels, runtime versions, and emergency launch warnings when an OTA update fails. Developers can track remote EAS Build lifecycle failures and successes using dedicated hooks configured in package.json. Performance instrumentation now supports span generation for Expo Router route prefetching as well as asset and image loading through wrapper functions around expo-image and expo-asset.


### [Introducing @supabase/server](https://yomu.fyi/post/introducing-supabase-server.md)
- Company: [Supabase](https://yomu.fyi/company/supabase.md)
- Author: tomas\_pozo, kalleby\_santos, katerina\_skroumpelou, matt\_johnston
- Published: May 6, 2026
- Type: Announcement

Supabase is releasing @supabase/server in public beta, a package for authentication verification, client setup, request context, and common server-side boilerplate across backend runtimes. Supabase says an anonymous analysis of 25,000 deployed Edge Functions found developers repeatedly rebuilding setup for clients, JWT verification, claims parsing, CORS, auth context, and shared files. The package's withSupabase wrapper or createSupabaseContext function supplies a SupabaseContext containing a user-scoped client, service-role admin client, verified identity, JWT claims, auth metadata, and auth mode, while declarative modes cover user, none, secret, publishable, or combined access. It returns standard Request-to-Response handlers for Edge Functions, Vercel Functions, Cloudflare Workers, Hono, Bun, and Deno, and includes primitives for custom middleware and adapters. @supabase/server does not replace @supabase/ssr, which remains focused on cookie-based sessions, and the release invites feedback on its public-beta API and adapters.


### [Introducing Application Metrics: Track the signal, see the spike, jump to the trace](https://yomu.fyi/post/introducing-application-metrics-track-the-signal-see-the-spike-jump-to.md)
- Company: [Sentry](https://yomu.fyi/company/sentry.md)
- Author: Ben Coe
- Published: May 5, 2026
- Type: Announcement

Sentry launched Application Metrics to capture application signals without pre-aggregating counters or discarding high-cardinality attributes like user IDs, project IDs, and regions. The system supports counters, distributions, and gauges within the existing SDK while linking each metric event directly to trace IDs for integrated debugging. Engineers demonstrated the feature by troubleshooting a Session Replay failure that triggered silently when sessions exceeded 1,000 video segments. By instrumenting distributions for replay event counts with project and replay attributes, the team isolated seven affected occurrences, navigated to connected traces and log lines, and reproduced the issue. Application Metrics comes enabled in recent SDK versions with 5GB included per plan.
