description	Debug Okojo.Node large-app failures through sandbox/OkojoInkProbe and sandbox/OkojoNodeDebugSandbox. Use this for Ink bring-up, reduced Okojo.Node repros, CommonJS/ESM/runtime compatibility debugging, debugger/disassembly investigation, and focused regression-driven fixes. Use when this capability is needed.

Okojo.Node Ink Debug

Use this skill for work under:

• sandbox\OkojoInkProbe
• sandbox\OkojoNodeDebugSandbox
• src\Okojo.Node
• src\Okojo
• tests\Okojo.Node.Tests
• docs\PALE_NODE_INK_DEBUG_WORKFLOW.md

Primary goal

Move sandbox\OkojoInkProbe forward by fixing real engine/runtime/compiler bugs and missing compatibility surfaces in a disciplined order.

Prefer:

1. correctness
2. observability/tooling
3. focused compatibility increments
4. measured optimization

Core policy

Do not treat large-app failures as app-specific until reduction proves they are.

Prefer:

• Node as the reference for Node-facing behavior
• V8 / Node bytecode behavior when the failure looks compiler/VM related

Avoid:

• broad speculative fixes
• Ink-specific hacks for general runtime/compiler bugs
• skipping the reduction step when a smaller repro is possible

Required workflow

1. reproduce in sandbox\OkojoInkProbe
2. reduce to the smallest JS shape possible
3. move the reduced shape into tests\Okojo.Node.Tests when stable
4. inspect disassembly / debugger state in sandbox\OkojoNodeDebugSandbox
5. compare with Node behavior
6. implement the narrow fix
7. rerun focused regressions
8. rerun Ink to reveal the next blocker

Read:

• docs\PALE_NODE_INK_DEBUG_WORKFLOW.md

before doing substantial work in this area.

Required tools

Real integration checkpoint

dotnet run --project sandbox\OkojoInkProbe\OkojoInkProbe.csproj -c Release -- --debugger

Focused debugger sandbox

dotnet run --project sandbox\OkojoNodeDebugSandbox\OkojoNodeDebugSandbox.csproj -c Release -- --app-root <appRoot> --entry <entry> --stop caught --log <logPath>

Use the focused debugger sandbox for:

• debugger; stops
• caught exceptions
• disassembly around the current PC
• locals/register inspection
• reduced app repros

Testing loop

Focused loop:

dotnet test tests\Okojo.Node.Tests\Okojo.Node.Tests.csproj -c Release --filter <Name>

After a fix, rerun nearby focused regressions before going back to Ink.

If the change becomes broad or touches shared compiler/runtime paths, expand validation appropriately.

Current known lessons

• the old Ink require(undefined) failure was actually a wide-register compiler bug
• dedicated debugger/disassembly tooling was necessary to prove the root cause
• AbortController support may be needed tactically for bring-up, but Abort* / Event* likely belong long-term in Okojo.WebPlatform / shared web globals

Deliverables expected from this skill

When using this skill, aim to leave behind:

• a reduced repro
• a focused regression test
• a narrow code fix
• a rerun of Ink showing either success or the next blocker

If the blocker changes, update the workflow note or the active session plan so other agents can resume cleanly.
