Sprint Scrum-of-Scrums Report

Weekly progress report for scrum-of-scrums. Compares two sprint snapshots, applies team-specific rules, and produces a markdown report with findings, trends, and trouble areas. Read-only on Jira (uses already-captured snapshots). Writes one report file into the sprint folder.

This skill is the Claude port of the user's "Scrum of Scrums" prompt template. It expects sprint-snapshot has produced at least two snapshots in the target sprint folder. Pairs naturally with sprint-plan (start-of-sprint) and sprint-review (end-of-sprint).

Quick start

/sprint-sos-report                                          → Aurora, current sprint, latest two snapshots
/sprint-sos-report Borealis                                     → single team
/sprint-sos-report Aurora --from "week 1" --to "week 2"     → explicit comparison
/sprint-sos-report Aurora --from "week 1" --to "week 1.5"   → mid-week re-planning churn
/sprint-sos-report Aurora --new-info "Added 2 devs, +10 pts capacity, churn from re-plan"
/sprint-sos-report Aurora --no-council                      → skip clarity-council

Parameters

Workflow

- [ ] Phase 1: Resolve config + load _sprint.md + _team-rules.md
- [ ] Phase 2: Pick the two snapshots (auto or explicit) + load both canvases + JSONL rows
- [ ] Phase 3: Diff the snapshots (added / removed / moved-status / changed-points / wedge delta)
- [ ] Phase 4: Apply team rules (overhead-adjusted velocity, in-review overhead, wedge balancing)
- [ ] Phase 5: Run clarity-council (findings + trends + trouble areas) unless --no-council
- [ ] Phase 6: Render and write the report
- [ ] Phase 7: Console summary

Phase 1 — Config

Same resolution as sprint-plan Phase 1. _team-rules.md is load-bearing here — wedge balancing, in-review overhead exclusion, and overhead-adjusted velocity all depend on it. Bootstrap if missing (per sprint-snapshot/REFERENCE.md).

Phase 2 — Pick the snapshots

1. Read {{output_root}}\_snapshots.jsonl. Sort rows by snapshot_at desc.
2. If --from / --to were supplied:

• Match each against the phase field. If no match, fall back to filename match (<phase>.canvas). If still no match, prompt with the available phases as options.

1. Otherwise pick [0] as to and [1] as from. If only one row exists, prompt: Capture a fresh /sprint-snapshot first / Cancel.
2. Echo the picked pair: "Comparing Aurora Sprint 2 — `week 1` (2026-04-08) → `week 2` (2026-04-15)."
3. Load both <phase>.canvas files. Parse issue cards exactly as sprint-plan Phase 3 (key, summary, assignee, points, status from card color or column position).

Phase 3 — Diff the snapshots

Build five sets:

Plus per-status point-flow:

done.points (to)         - done.points (from)         = velocity delta this period
in_progress.points (to)  - in_progress.points (from)  = WIP delta
in_review.points (to)    - in_review.points (from)    = review queue delta
todo.points (to)         - todo.points (from)         = backlog drain

Compute per-member delta (tickets and points moved per person) for the workload-shift section.

Phase 4 — Apply team rules

• Wedge balancing — let Δadded = sum(added.points), Δwedge = max(0, from.wedge_points - to.wedge_points). If Δadded - Δwedge ≤ 0 → "scope balanced via wedge". Else → flag as scope creep with the delta in points and a list of the contributing tickets.
• Velocity-relevant `done` points — sum done.points from to, then subtract any DONE issue whose summary matches a _team-rules.in_review_overhead.title_patterns entry. This is the number reported as actual velocity for the period.
• Overhead-adjusted member load — for any overhead member, surface nominal vs effective load so the report doesn't read "X is 100% loaded" when they're intentionally overhead-only.
• In-review overhead exception — when computing the "stuck in review" call-out, exclude items matching the in-review overhead patterns. They are expected to sit in review until sprint close.
• Zero-points policy — _team-rules.zero_points_policy: intentional means do not flag 0-point items.

Phase 5 — Clarity-council

Unless --no-council, invoke clarity-council via Skill with the personas list. Pass:

• The Phase 3 diff sets (added/removed/moved/changed/assignee)
• The Phase 4 derived numbers (velocity-relevant done, scope-creep verdict, per-member load deltas)
• Both _snapshots.jsonl rows (from, to) for raw context
• The trailing _snapshots.jsonl window (last 5 rows for trend context)
• The user's --new-info text if provided
• Their assignment: "Produce five short markdown sections: `## Key Findings` (3-7 bullets), `## Observations` (3-5 bullets), `## Possible Trouble Areas` (3-7 bullets, each with severity High/Med/Low), `## Trends` (3-5 bullets — the statistics-expert leads here, with prediction intervals where relevant), and `## Knowledge to Capture` (1-3 bullets — owned by the knowledge-manager, each naming a concrete artifact to update: a runbook line, an ADR draft, a CONTEXT.md entry, or a wiki page; include the confidence that the learning generalises beyond this week). Cite issue keys (JIRA:KEY) for any specific ticket claim. Cite the `--new-info` context when relevant. Strict: no fluff; no knowledge-manager bullet without a target artifact."

Specifically for the statistics-expert: they should compute and surface (1) period velocity vs avg, (2) carry-over rate (tickets in to that were also in from and not yet done), (3) projected end-of-sprint completion if the current pace holds, with a prediction interval. The persona's Output Requirements enforce the "no point estimate without uncertainty" rule.

Phase 6 — Render and write

Output path: {{output_root}}\reports\sos-<to-phase>.md. Phase label is preserved literally (e.g. sos-week 1.md, sos-week 1.5.md). Same overwrite-prompt rule.

Rules

• Read-only. Read snapshots, JSONL, sprint config, team rules. Don't modify any of them; don't call Jira directly.
• Always cite ticket keys. Council and skill output must use JIRA:KEY for any ticket-specific claim. Reject council responses that fail this rule and re-prompt.
• Wedge accounting is not optional when _team-rules.wedge.ticket_key is set and present in both snapshots. Compute and report the verdict; the SM uses this to defend scope.
• Velocity reported is always velocity-relevant (excludes in-review overhead). Surface raw separately when it differs.
• Statistics-expert forecasts must include a prediction interval. Reject point-only velocity forecasts.
• Never overwrite without confirmation. Same prompt pattern as the rest of the sprint-* family.
• Wikilink team members only when the vault note exists (same Glob rule as siblings).

Edge cases

• Only one snapshot in the sprint folder — prompt to capture a fresh one with sprint-snapshot first; do not run a single-snapshot "comparison".
• `from` and `to` are the same snapshot — refuse and ask for a different pair.
• `_team-rules.md` missing — bootstrap prompt; if user picks Skip, run with empty wedge/overhead but flag in console + frontmatter (team_rules: missing).
• Wedge ticket missing from one or both snapshots — fall back to "wedge accounting unavailable this period" warning; don't fail.
• `--new-info` includes capacity changes mid-sprint — capacity-vs-velocity warnings should explicitly account for the delta the SM described. (The council prompt passes the --new-info text verbatim so the personas can reason about it.)
• Mid-week re-planning snapshot (week 1.5) — supported by name. The user captures it via /sprint-snapshot Aurora --phase "week 1.5" and then runs /sprint-sos-report Aurora --from "week 1" --to "week 1.5".
• Council unavailable / `--no-council` — degrade to direct-LLM analysis; mark council_personas: [none] in the frontmatter.
