# Codex Skill E2E Run: Product Launch Email

Run date: 2026-06-04
Host: Codex
Mode: agent-native semantic rewrite, no CLI or regex rewrite pass

## Scope

- Surface: product launch email.
- Audience: practical product and editorial teams.
- Goal: improve launch-note quality by making the announcement direct, credible, and evidence-aware.
- Evidence policy: keep feature claims supported by the evidence file; soften any performance claim without benchmark support.

## Voice Profile

- Source: `sample.txt`
- Style: direct, launch-note oriented, skeptical of broad market claims.
- Rhythm: short paragraphs, clear "what changed / who it helps / what is rough" structure.
- Constraint: avoid pretending early signals are proven results.

## AI-pattern Audit

- Removed chatbot residue: "Great question!"
- Removed inflated language: "groundbreaking", "pivotal", "modern AI landscape".
- Replaced promotional phrasing: "seamless async collaboration".
- Removed formula: "not just a writing tool, but a trust layer".
- Flagged unsupported quantitative claim: "cut editing time in half for every team".

## Fact Decisions

| Claim | Decision | Evidence handling |
| --- | --- | --- |
| Workspace creates local voice profile, cleaner rewrite, and claim review | Kept | Supported by `evidence.md` |
| Markdown report made handoff easier for pilot users | Kept | Supported by `evidence.md` |
| Cuts editing time in half for every team | Removed/softened | Evidence says no controlled benchmark |

## Final Rewrite

Subject: A cleaner review flow for AI drafts

We shipped a workspace for teams that edit AI drafts together.

It builds a local voice profile, cleans up the draft, creates a claim review an editor can check, and exports the result as Markdown.

Pilot users said the report made editorial handoff easier. We do not have a benchmark for editing-time reduction yet, so I am not going to claim one.

## Final Audit

- Preserved supported product behavior.
- Removed unsupported editing-time reduction.
- Rewrote the "not just... but..." structure as complete sentences.
- Matched the sample's direct launch-note rhythm.
