eta-techlead - Retrospective

What Went Well

Rapid orientation: Ingested the full genmedia toolkit docs, the 7-step playbook, team brief, and all existing V1 artifacts efficiently. Was able to provide a complete technical assessment within the first few minutes.
V1 quality is solid: The previous eta-techlead delivered a production that passes every item on the Hard Verification Checklist — 1280x720, 3:39 runtime, 87MB real MP4, audio present, 37 shots assembled with crossfades, 17 VO stems, music ducking at -12dB.
Clean team communication: Exchanged functional messages with eta-editor and eta-pilot-coach. No wasted back-and-forth. The editor independently verified the same hard checks, confirming consensus.
Concept generatability: The claymation style chosen by eta-idea is arguably the optimal aesthetic for current generative models — forgiving of artifacts, strong textural vocabulary, and the two-character/two-setting constraint kept consistency manageable.

Late start relative to production: I was spun up after V1 was already complete and verified. My Step 1 generatability assessment was retroactive rather than proactive — the production decisions were already made and executed by a prior techlead instance.
No production work performed: This session was entirely review/verification. No images, video, voice, or music were generated. The synthesis rig was never fired.
Scion CLI message syntax: The set[...] notation for multi-recipient messaging required quoting to avoid shell glob expansion. Minor, but cost one failed attempt.

No failures in this session. The only risk was context waste from re-reading the full USAGE.md when the existing production was already wrapped. In a tighter context budget, skipping the full toolkit read and going straight to verification would have been more efficient.
Pilot coach response latency: Had to set blocked status while waiting for mission scope clarification. The turnaround was fast (~1 minute), but in a longer production this idle time would compound.

Decided to verify V1 before messaging the team: Rather than blindly accepting the brief’s “proceed to Step 1,” I ran genmedia-verify check and genmedia-assemble info on the existing final master first. This gave me concrete data to include in my team message and avoided sending an uninformed status query.
Chose to message both team and pilot coach simultaneously: Rather than waiting for one response before reaching out to the other, I sent the generatability assessment to the team and a mission-scope question to the pilot coach in parallel. This minimized idle time.

Brief should indicate production phase: When spinning up a new techlead instance, the brief should specify whether the team is starting fresh, mid-production, or in wrap-up. “Proceed to Step 1” was misleading when V1 was already delivered.
Include V1 status in the brief: A one-line note like “V1 complete, see final_master.mp4” would save the new agent from having to discover and verify the existing state independently.
The 21s audio tail: eta-editor flagged that credits music extends ~21 seconds past the video track end. For future productions, the timeline.json should trim the credits music to match the video duration or extend the title card. Simple fix via source_out on the credits clip.
Quote shell arguments for scion set[] notation: Document that set[a,b] must be quoted as "set[a,b]" to prevent zsh/bash glob expansion.
