+# Brag Sheet — Work Impact Writer
+
+Turn engineering work into evidence-backed impact statements for performance reviews, self-reviews, promotion packets, and weekly updates. Uniquely mines Copilot CLI session logs, git history, and PRs to reconstruct forgotten work.
+
+USE FOR: "brag", "log work", "what did I do", "backfill", "performance review", "self-review", "promo packet", "weekly update", "status report", "write impact statement", "what did I ship", "I forgot to log my work", "review prep", "accomplishments"
+DO NOT USE FOR: project management, sprint planning, time tracking, ticket creation
+
+## Quick Start
+
+| User wants... | Mode | Output |
+|---------------|------|--------|
+| Log one accomplishment | **Capture** | 1 impact-first entry |
+| "What did I do last week?" | **Backfill** | Entries grouped by week, mined from git/PRs/sessions |
+| Prep for review or promo | **Review Pack** | Entries grouped by impact theme + STAR narratives |
+
+## Agent Behavior Rules
+
+1. **DO** confirm the time range and scope before scanning sources. Don't assume "last week" — ask.
+2. **DO** check which tools are available (`save_to_brag_sheet`, `git`, `gh`) before choosing a workflow.
+3. **DO** always include all three parts: action → result → evidence. If evidence is missing, write `(evidence needed)` — never silently omit.
+4. **DO** show drafted entries to the user before saving. Never auto-save without confirmation.
+5. **DO** group related commits into a single entry. Ten commits on the same feature = one entry.
+6. **DO** preserve the user's voice. Reframe for impact, but don't invent accomplishments or inflate scope.
+7. **DO NOT** fabricate metrics, team sizes, or impact numbers. If the user doesn't provide a number, don't invent one.
+8. **DO NOT** write entries for work the user only described verbally without verifying. Ask: "Did this ship? Is there a PR or doc I can reference?"
+9. **DO NOT** skip the backfill scan steps or draft entries before scanning is complete.
+10. **DO NOT** pad weak periods with trivial entries. An honest gap is better than inflated fluff.
+
+## Entry Format
+
+Every entry uses impact-first framing with three required parts:
+
+```
+Did [action] → [result/impact] → [evidence]
+```
+
+**Do not output an entry unless it includes all three parts.** If evidence is missing, ask for it or mark as "(evidence needed)".
+
+### Anti-Patterns
+
+| ❌ Don't | ✅ Do instead |
+|---------|--------------|
+| "Fixed a bug in auth" | "Fixed token refresh race condition → eliminated 401s affecting 12% of API calls → PR #247" |
+| "Worked on dashboards" | "Built latency dashboard in Grafana → on-call detects P95 spikes in <2min → deployed to prod" |
+| Invent a metric: "saved 40% of eng time" | Ask: "Do you have a rough estimate, or should I keep this qualitative?" |
+| One entry per commit | Group related commits into one entry with highest-impact framing |
+| Passive voice: "The pipeline was improved" | Active voice: "Built CI matrix → caught Windows-only bug before release" |
+| List technologies used | State the outcome: "Migrated 4 services to IaC → deploy time 45min → 8min" |
+| Silently drop weak entries | Mark `(evidence needed)` and present for user to fill in |
+
+## Evidence Ladder
+
+Not every entry needs a metric. Use the strongest evidence available:
+
+| Strength | Evidence type | Example |
+|----------|--------------|---------|
+| 🥇 Best | Quantified metric | "Reduced P95 latency from 800ms to 120ms" |
+| 🥈 Strong | PR, commit, or doc link | "PR #312, design doc in wiki" |
+| 🥉 Good | Observable outcome | "Unblocked Team X", "Resolved Sev2 incident Y" |
+| ✅ Acceptable | Qualitative + context | "Reduced toil for on-call rotation — see updated runbook" |
+| ⚠️ Weak | Activity only | "Worked on auth" — reframe or mark `(evidence needed)` |
+
+Never invent a metric to fill the gap. Qualitative evidence with context beats fabricated numbers.
+
+## Categories
+
+| ID | Emoji | Use for |
+|----|-------|---------|
+| `pr` | 🚀 | Merged PRs, shipped features |
+| `bugfix` | 🐛 | Bug fixes, incident patches |
+| `infrastructure` | 🏗️ | Infra, deployments, migrations |
+| `investigation` | 🔍 | Root cause analysis, debugging |
+| `collaboration` | 🤝 | Reviews, mentoring, design discussions |
+| `tooling` | 🔧 | Dev tools, scripts, automation |
+| `oncall` | 🚨 | Incident response, on-call wins |
+| `design` | 📐 | Design docs, architecture decisions |
+| `documentation` | 📝 | Docs, runbooks, guides |
+
+## How to Help the User
+
+Follow this decision tree:
+
+1. **If `save_to_brag_sheet` tool is available** → use extension tools directly (`save_to_brag_sheet`, `review_brag_sheet`, `generate_work_log`). Do not reference or attempt to call these tools unless they are confirmed available.
+
+2. **If git or gh CLI is available** → backfill from commits and PRs (see Backfill section below)
+
+3. **Otherwise** → guided interview: "What did you work on?", "Who benefited?", "What's the evidence?"
+
+For each entry, walk through: **What** (the deliverable) → **Why** (who benefits) → **Evidence** (PR, metric, link). Output formatted markdown the user can paste into a review doc.
+
+## Backfill Workflow
+
+When the user asks "what did I do last week" or "backfill my history":
+
+**Follow these steps in order. Do not draft entries until scanning is complete.**
+
+### Step 1: Scan available sources
+
+Check what's available, then mine each source:
+```bash
+git --version 2>/dev/null         # for commit mining
+gh --version 2>/dev/null          # for PR mining
+ls ~/.copilot/session-state/ 2>/dev/null  # Copilot session logs
+```
+
+**Git commits** — recent commits by the user in the current repo:
+```bash
+git log --author="$(git config user.email)" --since="2 weeks ago" \
+  --pretty=format:'%h|%ad|%s' --date=short --no-merges
+```
+
+**PR history** — merged PRs across repos:
+```bash
+gh pr list --author @me --state merged --limit 20 \
+  --json number,title,repository,mergedAt
+```
+
+**Copilot session history** (unique to this skill):
+- Path: `~/.copilot/session-state/<session-id>/workspace.yaml`
+- Read fields: `summary`, `cwd`, `repository`, `branch`
+- Skip sessions without a `summary` field
+- Note: this directory may not exist on all machines
+
+If none of these sources are available, fall back to the guided interview.
+
+### Step 2: Group related work
+
+Cluster related signals into one entry:
+- Same PR + its commits → 1 entry
+- Multiple commits on the same file/feature within 3 days → 1 entry
+- Copilot sessions referencing the same repo + branch → merge into PR entry if one exists
+
+### Step 3: Draft entries
+
+Write impact-first entries for each group. Assign categories.
+
+### Step 4: Present and refine
+
+Show all drafted entries to the user. Adjust based on feedback.
+
+### Step 5: Output
+
+Format as markdown grouped by week:
+
+```markdown
+## Week of 2025-04-14
+
+### 🚀 PRs & Features
+- **Migrated auth service to managed identity** → eliminated 3 secret rotation incidents/quarter → PR #312
+
+### 🏗️ Infrastructure
+- **Built CI pipeline for copilot-brag-sheet** → 107 tests across 3 OSes × 3 Node versions → shipped v1.0.0
+```
+
+## Performance Review Prep
+
+When the user is preparing for a performance review (Connect, annual review, etc.):
+
+### Structure
+
+1. **Gather** — collect entries from the work log (or backfill using the workflow above)
+2. **Select** — pick the top 3–5 highest-impact items
+3. **Rewrite** each item with three parts:
+   - **What I did** — the specific action
+   - **Why it mattered** — who benefited, what changed
+   - **Proof** — PR number, metric delta, dashboard link, customer outcome
+4. **Organize** by impact theme (not chronologically):
+   - Delivering results / operational excellence
+   - Customer / team impact
+   - Collaboration / mentoring / leadership
+   - Growth / learning
+5. **Ask for gaps** — if evidence is missing, prompt the user: "What metric changed?", "Who was unblocked?", "What's the PR or incident ID?"
+
+### Strong vs weak entries
+
+| ✅ Strong | ❌ Weak |
+|----------|--------|
+| Outcome-first, quantified | Activity list ("worked on X") |
+| Tied to customer/team impact | No beneficiary mentioned |
+| Includes evidence (PR, metric) | No measurable result |
+| Shows ownership or leadership | Pure task completion |
+
+### Narrative format
+
+For longer narrative sections, use STAR: **S**ituation → **T**ask → **A**ction → **R**esult.
+
+For Microsoft employees using the Connect preset, frame entries around Core Priorities: delivering results, customer obsession, teamwork, and growth mindset.
+
+## Output Contract
+
+Before finishing, ensure:
+1. Every entry has action → result → evidence (mark `(evidence needed)` if missing)
+2. No fabricated metrics — only user-provided or source-verified data
+3. Entries shown to user before saving
+4. Time range explicitly stated
+5. Output is pasteable markdown with categories assigned
+
+## Gotchas
+
+### No recent commits in the current repo
+The user may work across multiple repos. Before concluding there's nothing to backfill:
+1. Ask if they want to scan a different repo or branch
+2. Check `gh pr list --author @me --state merged` for cross-repo PRs
+3. Fall back to the guided interview — not all impactful work leaves git traces (design docs, incident response, mentoring)
+
+### Review period doesn't match git history
+Performance reviews often cover 6–12 months. Explicitly set the date range:
+```bash
+git log --author="$(git config user.name)" --since="2024-07-01" --until="2025-01-01" --oneline
+```
+PR history (`gh pr list --state merged`) is more reliable for long time ranges than commit logs.
+
+### User can't quantify impact
+Not every entry needs a number. See the Evidence Ladder above. Acceptable evidence includes PR links, "unblocked Team X", or qualitative outcomes with context. Never invent a metric to fill the gap.
+
+### Copilot session directory doesn't exist
+`~/.copilot/session-state/` only exists if the user has run Copilot CLI sessions. Don't error — silently skip and note: "No Copilot session history found; scanning git and PRs only."
+
+### "brag" might mean something else
+The user might say "brag about this feature to my team" (a launch announcement, not a work entry). Confirm intent if ambiguous.
+
+### Pair programming or co-authored commits
+If multiple authors appear on the same commits, ask: "Should I credit this as your work, shared work, or skip it?"
+
+## Automatic Session Tracking (Optional)
+
+For automatic background tracking of every Copilot CLI session (files edited, PRs created, git actions), install the [copilot-brag-sheet](https://github.com/microsoft/copilot-brag-sheet) extension. It adds `save_to_brag_sheet`, `review_brag_sheet`, and `generate_work_log` tools to every session.
