Brag Doc Skill

Nobody remembers in December what they shipped in March — so good work goes uncredited at review time. A brag doc is the fix: a running, dated log of what you did and the impact it had, captured while it's fresh. This skill turns a pile of "stuff I did" into impact-first entries you can paste straight into a self-review or promotion-packet.

Required Inputs

Ask for these only if they aren't already provided:

• The win(s) — what you did (rough notes are fine; the skill structures them).
• Impact — the outcome and any metric (before → after, time saved, revenue, users) — even a rough one.
• Scope & role — your specific contribution vs. the team's, and who it affected.
• Date / period and any evidence (PR, doc, dashboard, kudos, ticket link).

Output Format

Brag Doc — [your name], [period]

Entries newest-first, grouped by theme (or quarter). Each entry is impact-first:

[Verb-led headline — the outcome, not the task] · [date]

• What I did: [the specific action and your role in it]
• Impact: [metric / outcome — before → after where possible]
• Scope: [who/what it affected — team, org, customers]
• Evidence: [link]
• Maps to: [the competency / ladder level it demonstrates — e.g. "cross-team influence"]

Example:

Cut onboarding drop-off 18% → 9%, unlocking ~$140k ARR · Mar 2026

• What I did: led the redesign of the 3-step signup flow; wrote the PRD, drove eng + design alignment.
• Impact: activation 41% → 52%; drop-off halved (measured over 6 wks, 20k users).
• Scope: owned end-to-end; affected all new signups.
• Evidence: [PRD] · [dashboard]
• Maps to: drives measurable product outcomes; cross-functional leadership.

End with a "Themes this period" summary — the 3–4 narrative threads your wins ladder up to.

Quality Checks

• Every entry leads with impact/outcome, not the activity
• Metrics include the baseline (before → after), not a bare percentage
• Your specific contribution is distinguished from the team's
• Each entry links real evidence
• Entries are tagged to a competency/ladder level, so the doc feeds a review or promo case directly

Anti-Patterns

• Do not log tasks ("attended planning", "wrote code") — log outcomes ("shipped X, which moved Y")
• Do not wait until review season — capture wins within a week, while the metrics and context are fresh
• Do not inflate or claim team wins as solo — overstated credit is worse than none when a manager checks
• Do not omit the metric because it's imperfect — a rough, labelled estimate beats "improved things"
• Do not bury the evidence — an unlinked claim is one a busy manager can't verify or champion
