hayba-debug-level

hayba-debug-level is a skill for Claude Code, Codex from zajalist/hayba. It costs 29 tokens per session (361 once invoked), scanned A, original, MIT.

A guided process for diagnosing performance, physics, or layout problems in an Unreal Engine level. A level is a playable game environment containing objects, rules, and geometry.

In plain words
What is it for?
Use it to investigate low frame rates, physics issues, floating or intersecting objects, and overly dense level areas.
Why use it?
It combines performance statistics, filtered logs, physics checks, and scene inspection to narrow down likely causes.

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

hayba-debug-level scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 22d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Diagnose a level symptom

When to use

Use for a concrete symptom such as floating objects, overlaps, missing generated content, low frame rate, or a streaming gap. Record the camera, active map, and reproduction steps so a later readback is comparable.

Tool routing

  • Start with hayba_check_ue_status. Gather a baseline through editor_get_performance_stats, editor_stream_log, and scene_export in hierarchical mode. Use wp_get_cells when World Partition is relevant.
  • For placement symptoms, run scene_validate_physics; inspect affected actors with actor_list and placement_validate before considering actor_transform or actor_set_visibility. A position that looks unusual may be an intentional user adjustment.
  • For generated content, use the hayba-pcg-build skill and a fresh cook readback. For performance, change one suspected cause at a time, then repeat the same measurement conditions.
  • For an accepted map repair, read back the changed actor or generated output, call level_save for the exact active map, and inspect saved, dirty, and verified status. If persistence cannot be checked safely, report the repair as unsaved and route it to hayba-world-save-integrity.

Evidence

Give the original symptom, baseline values or findings, the smallest confirmed cause, the edit made, and the after measurement. Run validator_run after scene edits. If measurements are unavailable, leave the diagnosis as a hypothesis rather than calling the level fixed.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
