Verify completeness
Skill jperrello/C0BALT_CUT/.claude/skills/verify-completeness
Arc-completeness gate. Re-reads each picked span's ASSEMBLED arc (the words inside its cuts) plus a tail lookahead and asks Claude whether the short LANDS as a standalone story — setup → turn → real landing, not an abrupt "so what?" stop. When the payoff is cut off but recoverable in the immediate source tail, it nudges t1 (and the last cut's end) OUTWARD to the landing sentence, within dmax. The outward counterpart to verify-bookends (inward-only). Runs after bookend-trim, before cut-clip, in SOURCE coordinates. Non-fatal, idempotent, disable with VERIFY_COMPLETENESS=0.From its SKILL.md

2 things to look at
- no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
- 2 stars2 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

verify-completeness
verify-coherence only checks that a span stays on ONE topic; verify-bookends
only inspects the first/last 1.5s of the already-cut clip and is deliberately
inward-only. Neither ever re-reads the WHOLE assembled story to confirm the arc
still LANDS. A pick whose payoff sits one sentence past the chosen t1 reads as
truncated — the channel's "cut off early" feeling.
This gate fills that hole. For each span it shows Claude the assembled arc (the
text inside the span's cuts, in order) plus a tail lookahead — the source
lines right after the current end, bounded by the remaining dmax headroom —
and asks for one verdict:
complete— the arc lands; no change.needs_more_tail— the landing is cut off but present in the lookahead; Claude returnsextend_t1, a source line-end boundary, and the span'st1(and last cut's end) are nudged outward to it, capped atdmax.truncated— abrupt but not recoverable within the lookahead/budget; flagged, left unchanged.
Why source coordinates / why here
Outward extension is only clean BEFORE cut-clip: once a clip is cut, trimmed,
and pace-tightened, the clip-local transcript has discarded source timestamps
(see rebase.py), so re-deriving where to extend in the source would mean
re-running the whole trim/tighten sub-chain. Running in source coords right
after bookend-trim lets any extension flow naturally through cut → trim →
tighten. This complements verify-bookends, which owns inward post-cut cleanup.
Usage
verify-completeness.sh <segments.json> <transcript.json> <out.json> [dmax=55]
- Batches all spans into ONE Claude call.
- Non-fatal: any Claude/parse failure passes segments through unchanged.
- Idempotent: skips when
outis newer than both inputs. VERIFY_COMPLETENESS=0disables (passthrough copy).- Biased toward
complete; only a short, clearly-landing tail triggers an extend.
Writes segments.json with completeness_verdict / completeness_note (and an
updated t1/cuts on a successful extend) into each span.

Said here and by no other author read
- batch all spans into one Claude call
- pass inputs through unchanged on any failure
- skip processing when output is newer than both inputs
- disable processing with VERIFY_COMPLETENESS=0
- bias verdicts toward complete
- extend t1 and last cut's end on needs_more_tail
