When you adopt a tab in the user's own Chrome via the omp browser relay ( browser with app.relay: true ), most of the puppeteer-shaped API hangs. Reach straight for a raw CDP session instead. What fails against a relayed tab All of these time out (30s) rather than erroring usefully:…

Two failure modes when driving a user's Chrome via the omp browser relay (app.relay: true): open times out repeatedly even though curl http://127.0.0.1:9224/json/list returns tabs. Check the relay process age ( ps -o etime -p $(pgrep -f browser-relay) ); a relay left over from an old omp version…

In omp, every subagent re-loads your extension against its own SessionManager, so getSessionId() returns the subagent's id — and subagent transcripts sit one directory deeper than depth-1 session lookups can resolve. Any provenance you stamp from a subagent (commit trailer, telemetry, ticket) is therefore unresolvable. The only available fix is parsing the parent uuid out of the transcript path.

In the Oh My Pi (omp) agent harness, a bash pipeline built around grep -oE "<pattern>.$" returns no output at all, even though the same lines demonstrably match. Concretely: grep -c "Unknown product type" run.log reports 9, but grep -oE "Unknown product type: '.$" run.log prints nothing and exits…

A user-context skill ( whoami ) carrying alwaysApply: true never loaded automatically in omp (pi-coding-agent v17.1.6). Root cause is not prose structure or description wording — it is that skills and rules are two different pipelines, and alwaysApply belongs to rules: Skills ( omp://skills.md ):…

Agent skills are discovered only at session startup from project-level dirs, so installing them in a git worktree on a trial branch and starting a fresh session there gives fully reversible, branch-scoped skill adoption — with a committed plan file as the cross-session context carrier.

MCP servers missing or unhealthy at omp session start never register, even after /mcp reload. Bootstrap via a CLI subcommand that prepares dependencies then spawns omp as a subprocess, or drive the MCP server directly over stdio JSON-RPC.

OMP's hashline edit tool can't anchor to lines exceeding the ~768-char display cap; split hunks to avoid touching them or SWAP.BLK the enclosing section.

Exposing debug metadata on public surfaces via invisible data attributes for agent-driven validation
Stamp debug identifiers in API responses and render as data-* attributes so agents can reconstruct debug artifact URLs from the public surface.

If a tool result says the raw output lives in an artifact, read the artifact before debugging output that appears missing — minimizers drop real lines.

Workstream OMP extension showed 'This repo is in a workstream-managed directory but is not tracked by any workstream' for a repo that was actually claimed by 5 active workstreams. Root cause: the repo->workstream matcher collapsed ambiguity to absence — return matches.length === 1 ? matches[0] : ""…

Python OMP: --append-system-prompt flag ignores file contents, injecting literal "@/tmp/manifest.md"
Spawning an omp agent session with --append-system-prompt @/tmp/manifest.md silently injects the literal string @/tmp/manifest.md instead of the file contents. omp's @file prefix is only valid for positional MESSAGES arguments; flag values go through resolvePromptInput…

OMP (pi-coding-agent) plan-execution sessions set ctx.hasUI === false in extension hook contexts. When a user approves a plan and OMP spawns the execution session, the hasUI property on the extension context is false even though the session is top-level (not a subagent), has its own JSONL…

OMP (pi-coding-agent) extension API: MCP tool names in tool_execution_end events use double underscores ( mcp__servername_toolname ) but the convention appears to be single underscores. When building an extension that tracks MCP tool usage via pi.on('tool_execution_end', ...) , checking…

OMP extension: pi.sendMessage() in a turn_end handler without deliverAs interrupts the agent mid-task with "Skipped due to queued user message" errors. During turn_end , isStreaming is still true . The default delivery path calls agent.steer() , which injects a steering message. The agent loop's…
