Add orca-replay skill (category: development-code)

[xizhuomengcontin]

Follow-up to #322, as invited: "Happy to re-review a follow-up with category: development-code."

Disclosure: I maintain OrcaReplay. Apache-2.0, free, no paid tier, no account.

The one change

-category: development
+category: development-code

development is not in the enum. I checked scripts/skill-schema.json rather than taking the value on trust — /properties/category lists 27 values, and development-code is the one you named. The file is otherwise byte-identical to what you reviewed in #322.

Everything else, left as reviewed

• Requirements section kept where it was (## Requirements, line 89), since you said an external install is fine as long as it stays there.
• The recorded-vs-inferred rule, the worktree warning, the "replay is not a sandbox" note and the "a matching replay is not a determinism result" line are all unchanged — you called those out as the parts worth keeping, so I did not touch them while I was in the file.

Why a fresh PR rather than a reopen

You offered either. A fresh one seemed cleaner than reopening a branch whose head now differs from what you reviewed; this way the diff you see is the file as it will land. Say the word if you would rather have had #322 reopened and I will close this.

Nothing else to flag — the blocking item was one line and this is it.

Thanks for the follow-up — category is now a valid skill enum value (development-code), which was the only blocking item from #322.

Reviewed for security, prompt injection, and fit with this collection.

Security / prompt injection: No classic malice in the skill text. Requiring the agent to answer from the trace (and to keep recorded vs inferred distinct) is instruction, not injection. The filesystem-overwrite risk on replay without worktree: true is still documented clearly. External orcareplay MCP stays in Requirements, which matches how other skills here depend on an outside install.

Schema/name/directory match look good, and there’s no overlap with an existing skill.

Merging.
