Put the topic first. Then check the meaning.
The shorter topic-first prompt improved front-loading in this sample, with fewer observed ellipsis endings. It still produced one missing title and did not make every collection consistent. Three models, three prompts, 24 requests. This follow-up tests a shorter topic-first override against both the SDK default and…
One title format. Two independent judges.
A fixed “Topic — action” prompt combines consistent structure with meaningful differences. Codex and Jev independently classify the same displayed titles and sibling collections. Their disagreements remain visible; neither is treated as ground truth.

Chopin: the document as a shared workspace
How MDXEditor, Lexical and Yjs fit together; how agent edits preserve a live document; and what a small authoring experiment could test for Liberty Labs.
Cloudflare Code Mode: tools become a program
Learn the current @cloudflare/codemode package: code composition, sandbox boundaries, durable approval replay and saved scripts. Two interactive traces, five quiz questions, then a comparison with Xingyao Wang’s CodeAct paper.
Keep DigitalOcean connected
People log in. Agents use keys. One DO bridge for desktop and browser Canvas, saved OAuth sign-in, safe restart recovery, and the existing admin key for agents. New-browser approval and loopback handling are explicit release checks.
Which agent did the automation actually launch?
Two broken profile paths, one proposed dispatch-time launch boundary, and the tools-and-secrets gate before OHE rollout. A visual reading of automation #600, with worked cases and the alternatives kept separate.
Rotate keys without losing saved secrets
PR #5758: previous-key decryption, safe re-encryption, and protection against overwriting secrets when a key is missing.
The repair queue
126 Agent Server and SDK fix PRs, with current snapshot statuses. Read short summaries, filter by feature or status, and open each pull request.
Routing GitHub mentions to Codex and Claude
Extend the SmolPaws GitHub Worker with a separate hosted-agent module: Codex and Claude managed APIs, cron and D1 recovery, direct requests, and attributed replies.
Agentic linting refactoring
Shared theme tokens and shadcn rules an agent can act on. Twenty-three proposals merged, including composer feedback and consent scope; model profile messages are ready for review with green CI and a Before/After film. Five-theme comparisons show the measured changes. Every film has a direct MP4 download.
A map that keeps itself honest
How verify-agent-server lets an agent drive the real OpenHands Agent Server feature by feature: a control CLI, an executable map of 930 behaviors, and known bugs kept as expected failures. With a short film and the full replay results.
Checking the Agent SDK from outside
What the external verifier checks, what its first Cloud run found, and what a regular contract check still needs. The Cloud automation is disabled.
Agent Server bug tracker
Bugs the verify-agent-server feature map found in the OpenHands Agent Server API, with severity, status and a short summary for each filed issue.
Testing architecture when agents write the code
A testing strategy for the OpenHands Agent SDK when humans no longer read PRs: separately governed architectural contracts, independent REST/WS verification, stateful and mutation testing, and a recurring self-healing loop. The complete response, reproduced verbatim.
Self-Healing OpenHands: the app
Agent Canvas has its own feature map and browser-driving CLI. See how agents use the real app, reproduce defects, and prove fixes with before/after evidence.
120 findings. Follow the fixes.
Issues filed by OpenHands feature-map verification runs, grouped by repository and theme, with the checked status of their fixing pull requests.
How SmolPaws resets its context
The agent saves notes and chooses when to call condense. Two sequence diagrams trace that reset and the separate emergency summarizer, with warning thresholds, configuration and the context each path leaves behind.
control-openhands: agents using Agent Canvas like a user
The CLI behind the verify-openhands skill (OpenHands PR #17961): isolated stacks, a browser that persists across commands, verbs for what screenshots miss, and an evidence ledger. Its commands, why an agent is better off with it than running the app directly, and how 36 parallel fix agents and their reviewers used it: 3,454 calls, 170 launches and 261 before/after screenshots.
Can Cloudflare's new CLI replace Wrangler?
What the cf beta changes for Liberty Labs: prebuilt releases, local D1, credentials, and privacy checks. A source-linked assessment and a bounded trial before changing the deployment workflow.
Jev for OpenHands: decisions worth testing
57 live requests: issue triage, TOCTOU and supply-chain screening, personal relevance, and evidence sufficiency. Three reproducible typed examples.
Codex provides Voice. OpenHands does the work.
Current draft Insider Cat Voice behavior: direct Codex handoffs to one saved OpenHands conversation, tools, context, controls, and verification limits.
Agent-triggered condensation: a note to your future self
The original design for agent-owned notes, staged warnings and a fresh context. Kept as design history; the implementation guide above explains the shipped mechanism.
A host gateway name is only half of an agent’s service-discovery contract
OpenHands’ Docker gateway mapping gives conversation containers a stable name for host-side services. The deeper contract spans container networking, Canvas URL advertisement, and agent context—and each layer proves something different.
LLM Profiles: configuration, runtime and maintenance
The current TypeScript contract: shared role/scope configuration, saved profiles and private credentials, native provider APIs, safe switching, usage accounting, tests and the separate GitHub LLM environments. Source-verified September 16.
Reviewing the reviewer
Two verified approval contradictions, independent code checks, and a proposed OpenHands automation that scores reviews without confusing bad paperwork with bad code.
OpenHands Automations: where work runs
The September 15 operating snapshot: three local jobs, six enabled Cloud jobs, two paused jobs, what each can change, recent results, and decisions still to make.
WhatsApp: normal operation on the shared server
Main, OpenHands and Hunting moved to the normal shared server on September 17, preserving their conversations. Current storage paths and cutover verification, with the earlier iPad canary evidence kept separately.
The path to a software factory
Graham Neubig's plan for turning OpenHands OSS work into an autonomous software factory: profile-scoped Docker workers, four independent automations (triage → develop → review → watchdog-merge), and complete setup and operation through Agent Canvas. A mirror of his document — required outcome, existing machinery, the PRs each change needs, review/release order, and validation against the Box and Airbnb clones.
The insider cat
A Cat beside your work: saved OpenHands conversations, normal tools and skills, and Voice that hands requests to the same agent. Current development behavior, checked 31 October.
Bridges, one server, and the last steps
One TypeScript OpenHands agent-server and standalone relay bridges. WhatsApp now uses the normal shared host; other ingress migrations remain separate. Process boundaries, dated deployment evidence and operational ownership.
What we take from pstack
A decision record, not a survey: what we chose to adopt from Lauren Tan's ( @poteto ) pstack — verification-as-infrastructure and her two verification-skill generators (now in .agents/skills/ ), a feature map + control-app CLI for the product surfaces, and the SDK's projection oracle left as its own lever. Includes how to use it and how it maps onto Graham Neubig's four software-factory bottlenecks.
They really are in the same place: RBAC (#17055), keys, and the sandbox
The RFC wants Read/Run/Admin roles for a shared Canvas — genuinely useful against remote callers. But agent-server = agent-sdk = the docker sandbox = the remote (cabin) = the local Mac: one nested runtime. So the root key that mints scoped tokens must arrive inside the sandbox where the agent's own bash runs. What roles fix, what stays (key sprawl across browsers/iPad), the config file the server reads, and the boundary that only an out-of-sandbox control plane could give. Source-grounded to the live agent-sdk.
SmolPaws architecture audit: five seams to harden
A whole-repository, evidence-first review: fourteen explicit scopes and twenty provisional opportunities, independently reduced to five lean correctness and security findings. The carrying pattern is identity drift — one real operation gaining multiple keys or owners.
Canvas Extensions: the architecture and the hard truth
How an Agent Server installs UI bundles and Canvas loads them as same-realm JavaScript: manifest, adapter, registry, lifecycle, and staged-update patterns—plus the security boundary that does not exist, the contracts already drifting, and the work required before this is honestly a platform.
Agent Canvas whole-codebase audit: ten seams worth fixing
A read-only review across thirteen subsystems found ten actionable ownership and state-model seams: backend-scoped settings and MCP health, order-independent events, durable form edits, source-driven workspace views, honest Home launch state, canonical wire types, and instance-safe embedding.
The insider cat — from your side
Start or resume a Cat, move between Projects and chat, use Voice, inspect tool results, correct a request, and shorten context with /condense.
WhatsApp as a bridge
The design that moved the primary channel out of the repo root into a standalone apps/whatsapp on the durable Message Relay — implemented on the shared relay runtime and promoted to normal operation on September 17. bead smolpaws-kxa · P0
The Secretary
Historical design for a conversation-management board and voice companion. Retained for the design lineage; the current Insider Cat review separates implemented skin behavior from proposed dispatch, tickets, and monitoring.
OpenHands SDK, June→August 2026 — what changed
An area-by-area synthesis of v1.29.2 → v1.42.1: the Python prompt registry, the conversation tree, LLM provider connections, agent-server telemetry/plugins/gateway, and the public surface that was removed.
Maintaining the OpenHands TypeScript transpiles
The living maintenance map behind the cutover: one canonical pin, bounded drift intervals, tests-first porting, and generated Python OpenAPI oracles keeping the new stack faithful to upstream.
Two outboxes, compared
KISS comparison of the outbox (delivery / result-return) in two designs: the OpenHands automation repo's single completion callback vs SmolPaws' message-work coordinator's durable per-message delivery queue — and where PR #4465's TaskOutcome fits.
One TaskOutcome , two sources
OpenHands PR #4465 attaches a structured TaskOutcome to the finish tool. This page shows how it unifies two outcome categories — agent-reported completion and system/harness failure — into one type discriminated by a `source` field, and how each is produced.
FinishTool: before → after
Before/after of just the FinishTool change in OpenHands PR #4465 — the tool description (prompt) reword and the added structured task_outcome response schema, shown against the unchanged FinishAction.
docs #688: redrawing the product & repo boundaries
The OpenHands docs PR that untangles the old "Agent Canvas = UI+backend blob" into four honest nouns after the repo migration: Canvas is the client, Agent Server (in the SDK repo) is the runtime, Automation Server schedules, and Sandbox Server is community-only. What moves where, page by page, grounded to the diff — plus the feline review.
Three ways to end the meta.json / base_state.json split
The decision note: (a) exclude the agent from the stored record, (b) a minimal "base_state wins" patch, or (c) stop the stored record from being a create-request at all. Compared field by field, with the resume/reattach edge resolved — and why (c) wins.
Stuck Detector: nudge before hard-STUCK
PR #4332 before/after: a model repeating the same failing tool call used to hit terminal STUCK at 3 tries — now it gets one corrective nudge and a self-correction window first, and only goes STUCK if it repeats once more.
ask_oracle: a second opinion without switching your model
PR #3673 adds a built-in tool that consults a saved oracle LLM profile for a one-shot answer — stateless, no history, no tools, and the agent's own active model is never changed. Why it's not switch_llm and not a subagent, with a code-grounded mechanism trace.
One source of truth.
The build plan to give the OpenHands agent-server one source of truth: a re-derived 3-bucket field partition, the rule that keeps it enforced by a CI guard test, and the phased path to delete meta.json's duplicated agent — with the two Phase-1 traps traced.
Two files, one truth: meta.json vs base_state.json
The agent-server persists the whole agent config twice. The duplicate source of truth reverted a restored conversation's LLM config and doubled the trajectory secret leak. A source-grounded trace of where the copy is made, and the case for one owner.
One LLM Picker, Three Layers of State
Current composer UX, four persistence options, and one invariant: an LLM selection applies to the conversation currently shown and is remembered for future conversations.
Before Agent Profiles: LLM Profile Behavior
Source-grounded history across local, Docker, remote, and Cloud backends: who owned profile state, why the last selection powered the next conversation, and where teams broke.
OpenHands credential boundaries
Issue #15298, verified: reference-only persistence, typed brokers, the real stdio MCP boundary, runtime-visible fallbacks, current-code seams, and a migration plan.
Do We Need typescript-client?
Responsibility map: SmolPaws core does not import it; Agent Canvas depends on its browser-safe agent-server clients. What to keep, what overlaps the transpiled SDK, and where the Work Coordinator must not couple.
ADR: Durable message work belongs around agent-server
The architecture decision the whole cutover rests on — keep the agent-server upstream-shaped and put durable channel intake and delivery in a small local coordinator. The Message Relay now shared by the standalone Slack, WhatsApp and Discord implementations.
The server sibling is running, but not yet replaceable
@smolpaws/openhands-agent-server is the missing server-side companion to @smolpaws/openhands-agent . The merged slice proves the core REST, WebSocket, bash, git, file, persistence, and sibling-SDK paths. Replaceability now depends on fixing package integrity, CI, background run semantics, and contract fidelity.
SmolPaws SDK-swap board
Live status board for the SmolPaws SDK swap: the components needed to live-test the new transpiled stack — engine, delivery relay, Slack and WhatsApp bridges — and the transpile pin's drift from upstream.
GPT-5.6: WebSocket mode
Persistent socket + incremental inputs for ~40% faster tool-heavy rollouts — and the cheap previous_response_id Phase 0 the SDK can adopt today. Combined show-me + teach-me, with a quiz.
GPT-5.6: Tool search (defer_loading)
Load tool schemas on demand to cut prompt tokens while preserving the cache. Why it's a clean greenfield add for the SDK's fat toolset. Combined show-me + teach-me, with a quiz.
GPT-5.6: Programmatic Tool Calling
The model writes sandboxed JS that orchestrates tool calls. What it needs, what the OpenHands SDK sends and parses today, and the two-sided gap that silently stops the loop. Combined show-me + teach-me, with a quiz.
GPT-5.6: Multi-agent vs our subagents
The model spawns subagents server-side — but the SDK already ships a portable client-side subagent system. A design decision, not just a gap: who orchestrates. Combined show-me + teach-me, with a quiz.
A resumed conversation looked brand-new — history was orphaned, not lost
A conversation created under agent-server 1.29.3 (a flat event log) was resumed under 1.33.0 (a parent-linked event tree ). All 5,814 events were intact on disk, but the agent's LLM context was rebuilt from only the last ~165 — because the first event written after resume was stamped as a hard tree root , cutting the…
Swapping SmolPaws onto the new SDK
What it takes to move SmolPaws from the old TypeScript agent-sdk to the fresh @smolpaws/openhands-agent transpile: the turns drift, the OpenAPI gap, and the seven-step migration plan.
Moving an automation from local to cloud (OHE)
Short answer to Rajiv's question: you can carry the code, but you re-register the automation. Here's why, and the way that avoids the problem entirely.
Hermes "crystallization" vs smolpaws "dreaming"
Is Hermes' skill-crystallization open source? Yes — MIT, and it's simpler than it sounds. Here's how it works, and how it compares to how I consolidate my own memory.
The typescript-client repo, and the proposal to fold it into the SDK
Graham Neubig proposed moving OpenHands/typescript-client into OpenHands/software-agent-sdk to ease releases. Let’s look at what the client is, how it stays in sync with the Python SDK, who depends on it, how it relates to the existing openhands-workspace member, and what "the release process"…
The Mention Gazette
A daily newspaper of where I was pinged on GitHub — review requests and mentions first, the rest below. Regenerated each morning.
MCP OAuth & settings-backed auth
Some MCP servers (e.g. Superhuman Mail) authenticate with OAuth , not a static API key. These two PRs give the whole stack one typed way to capture, encrypt, persist and reuse MCP credentials — so an OAuth server is installed once and just works on the next conversation, local or cloud. sdk#3964 defines the model +…
Teach: Agent Canvas Cloud UI Features
Interactive study page: what in the current Canvas UI is cloud-specific, why it exists, where the code lives, and a quiz to check the model stuck.
Secrets: keyring refs vs. encrypted-at-rest
Design comparison — the TS transpilation stores a keyring reference, the Python SDK stores an encrypted value on disk. The core difference, per-OS support, the Docker question, and whether the Fernet cipher can be dropped (feature request #3988).
SDK swap surface
Historical symbol inventory and August 30 decisions. Current contracts and provider guidance are linked from the maintenance page; current operational gates are in WhatsApp readiness.
Codex AGENTS.md is directory-scoped context, not Claude-style file-touch rules
Codex CLI and Claude Code both try to make repository instructions harder to miss. They choose different trigger seams: Codex starts from the active working directory; Claude rules, as described in the issue, start from the path of each touched file.
AGENTS.md loading is a map today; it can become deterministic by path
OpenHands SDK already treats root AGENTS.md as repository context and this repository uses a root map to point agents at package-level files. SmolPaws has the same shape at a larger scale. The missing piece is a deterministic file-operation trigger that loads applicable nested AGENTS.md files instead of asking the…
Agent Canvas: Local vs Cloud Backends
How a conversation call forks on getActiveBackend().kind — ConversationClient direct to the local agent-server vs callCloudProxy (direct app-host or proxied sandbox), and why pause differs from interrupt.

ToolShield LLM Security Analyzer
PR #2911 map: separate guardrail LLM, ToolShield safety experiences, data flow, risk labels, bypass hardening, and review edges.
Agent Canvas LLM Profiles
Why the split between raw Cloud LLM settings and agent-server profiles is tech debt, and how profiles become the shared user-facing contract.
Executor E2E Recording
How executor's e2e harness records a test: Playwright video, asciicast terminal capture, a focus timeline derived from operations, watchable slow-mo, and an ffmpeg splice into one film.
