Retrospective

Sprint Retrospective

Generate a sprint retrospective for this project. If the project CLAUDE.md has a Sprint retrospectives section with a template, use it; otherwise use the template below.

Context

Retrospective files are named RETRO-NN.md in the project root. Each covers one sprint's worth of work.

Workflow

Beads availability

Beads is available iff a .beads/ directory exists and command -v bd succeeds; this component is Tier C per CLAUDE.md ### Beads-availability convention. Steps 1–3 and the UPSTREAM / SYNERGY / Basic Memory parts of the trend review are beads-independent and run unchanged. When beads is unavailable, the three bd-dependent steps degrade and announce (never skip silently):

• Health audit (step 4) — replace the bd health checks with an announced skip line in the RETRO ### Health audit subsection (see step 4).
• Findings (step 5) — append a ### Follow-ups (untracked) task list to the RETRO file instead of running bd create (see step 5).
• Decision capture (step 5) — record decisions inline as a ### Decisions block in the RETRO file instead of bd create --type=decision (see step 5).

1. Determine sprint number

ls RETRO-*.md | sort -V | tail -1

Extract the highest sprint number and increment by 1.

This file count is canonical for the trend-review heuristic in step 4 — do not substitute a user-asserted topic number, release number, or bd sprint label. If RETRO-NN.md count is divisible by 4, this IS a trend-review sprint regardless of how the work is verbally framed.

2. Gather context

Run these in parallel:

Recent commits since last retro:

# Anchor to the commit that created/last modified the previous RETRO file.
# Edge cases that both result in full-history range (correct for Sprint 1):
#   1. No prior RETRO-*.md files exist yet
#   2. RETRO files are gitignored — git log -- RETRO-*.md returns empty
# In both cases the inner git log returns empty, making the range "..HEAD"
# which shows all commits — the right behavior for a first retrospective.
git log --oneline "$(git log -1 --format=%H -- RETRO-*.md)"..HEAD --no-merges

Current upstream status:

• Glob for all UPSTREAM-*.md files and read them
• Count open items per file and per section

Current synergy status:

• Glob for all SYNERGY-*.md files and read them
• Count open entries per file and per section
• Highlight actionable items: Extraction Candidates with Readiness: ready, Divergences with Convergence path: adopt-theirs or propose-shared, They Have / We Don't with Priority: adopt-soon
• Note any Shared Patterns with Status: drifting

Recent conversation context:

• Review the current session for friction, workarounds, discoveries, and decisions made during development

Test and coverage status:

Check package.json scripts for a test command. Try in order:

1. npm test (if a test script exists)
2. npm run test:node (if a test:node script exists)
3. npm run test (if a test script exists under another variant)
4. npm run check (if a check script exists — used by validation-suite projects like this one, vp-knowledge, vp-git)

Run the first that exists and show the last 5 lines of output.

3. Draft the retrospective

Create RETRO-{N}.md using this template (omit ### Synergy observations if no SYNERGY-*.md files were found in step 2):

## Sprint {N} Retrospective — {YYYY-MM-DD}

### What went well

- ...

### What could improve

- ...

### Upstream observations

<!-- Review recent work — anything to add to UPSTREAM-*.md files? -->

- ...

### Synergy observations

<!-- From SYNERGY-*.md: extraction-ready candidates first, then drifting
     patterns, then active convergence paths. Omit if no SYNERGY files. -->

- **Extraction Candidates ready:** <!-- e.g. "validate-helpers (vp-knowledge) — Readiness: ready" or "none" -->
- **Drifting shared patterns:** <!-- e.g. "BM note format — drifting since 2026-01" or "none" -->
- **Active convergence paths:** <!-- e.g. "error handling — adopt-theirs from vp-knowledge" or "none" -->
- **New patterns logged this sprint:** <!-- e.g. "Logged 2 new Extraction Candidates" or "none" -->
- **Stale entries flagged:** <!-- entries >3 months old, or "none" -->

### Lessons learned

- ...

Section guidelines:

• What went well — concrete wins: bugs caught, patterns established, clean commits, test improvements. Reference specific files/commits. Focus on process and engineering quality, not just features shipped.
• What could improve — honest assessment of friction, false starts, wasted effort. Not a blame list — focus on systemic issues and what would prevent recurrence.
• Upstream observations — summarize current state of all UPSTREAM files. Log any NEW friction discovered in the session to the appropriate UPSTREAM file using /upstream-tracker workflow 1 (Log a new entry). Review recent session work — did any workarounds or local extensions get built this sprint that are self-contained enough to contribute back? If yes, log via /upstream-tracker workflow 1 (Log a new entry) with type "Upstream Opportunity". Note trends across packages. Flag stale items (>3 months old).
• Synergy observations — summarize current state of all SYNERGY files. Log any NEW cross-project observations discovered in the session to the appropriate SYNERGY file using /synergy-tracker workflow 1 (Log a synergy entry). Report extraction candidates with Readiness: ready as sprint-actionable. If any candidates were acted on this sprint, record the outcome. Review recent session work — did any implementation reveal shared patterns with sibling projects, or produce logic worth extracting into a shared package? If yes, log via /synergy-tracker workflow 1 (Log a synergy entry). Note trends across sibling projects. Flag stale entries (>3 months old). If no SYNERGY files exist, omit this section from the generated RETRO-NN.md entirely.
• Lessons learned — reusable insights. Each should be a principle that future sessions can apply, not a one-off fact. Format: Bold principle — supporting evidence from this sprint.

4. Check for trend review

If this is every 4th sprint (Sprint 4, 8, 12, ...), also perform a trend review: (Sprint number is the file count from step 1, not a topic-asserted number.)

UPSTREAM files: Review all UPSTREAM-*.md files — identify common trends, evaluate whether open items are still valid, delete non-vendor files with no remaining entries.

SYNERGY files: Review all SYNERGY-*.md files — identify stale entries (>3 months), evaluate whether Shared Patterns are still aligned or have drifted, check if Extraction Candidates with Readiness: ready have been acted on, and review whether adopt-theirs Divergences have been adopted.

Health audit: Run bd's full health vocabulary in parallel — five focused checks covering infrastructure, template compliance, lifecycle hygiene, reference integrity, and dependency-graph integrity. Each command emits JSON for stable parsing. Surface counts plus the top 3–5 affected items per check in the generated RETRO-NN.md under a ### Health audit subsection.

Beads unavailable (Tier C): skip the bd health checks and render the subsection as a single announced line instead — - _Skipped — beads not active in this project._ The UPSTREAM and SYNERGY trend-review parts above and the Basic Memory graph health below are beads-independent and still run.

bd doctor --json    # Infrastructure: outdated hooks, gitignore drift, remote config
bd lint --json      # Template compliance: issues missing required sections per type
bd stale --json     # Lifecycle: issues with no recent activity
bd orphans --json   # Reference integrity: refs in commits but issue still open
bd graph check --json  # Dependency graph: cycles, dangling refs (schema_version: 1)

Per-check guidance:

• bd doctor --json — parse warnings[]. Auto-fix is gated on user consent: present the warning list and prompt before invoking bd doctor --fix --yes. Never auto-apply. Note the false positive on the Claude Hook Completeness check — it sometimes flags hooks that are intentionally absent or installed via a plugin (see UPSTREAM-brew--beads.md for the open friction entry); skip the prompt for that warning class until it is resolved upstream.
• bd lint --json — parse issues[]. No auto-fix; lint findings require human triage. List affected issue IDs with the missing section names so the maintainer can update them (e.g., bd update <id> adding ## Acceptance Criteria to a feature).
• bd stale --json — parse issues[]. No auto-fix; suggest one of three human actions per issue: defer (lower priority), close (no longer relevant), or work (claim and progress).
• bd orphans --json — parse issues[]. If --json is unavailable on the installed bd version, fall back to text parsing of bd orphans output. No auto-fix; suggest closing the issue or unmarking the orphan reference.
• bd graph check --json — parse the schema-versioned envelope ({"clean": bool, "cycles": [...] | null, "schema_version": 1, "summary": {...}}). When clean: false, surface cycle paths and dangling refs with fix recommendations (typically bd dep remove <blocker> <blocked> to break a cycle, or bd close for stale references — bd dep uses subcommands, not flag-form). No auto-fix.

Render in the RETRO file as:

### Health audit

- **Infrastructure (`bd doctor`):** {N} warnings — {top items, or "clean"}
- **Template compliance (`bd lint`):** {N} issues — {top items, or "clean"}
- **Lifecycle (`bd stale`):** {N} stale issues — {top items, or "clean"}
- **Reference integrity (`bd orphans`):** {N} orphans — {top items, or "clean"}
- **Dependency graph (`bd graph check`):** {clean | N cycles, top items}
- **Stats (`bd stats`):** {total / open / in_progress / closed / ready / blocked counts}
- **Blocked review (`bd blocked`):** {list blocked issues; for each, run `bd show <id>` to identify its blockers and flag any blockers whose status is currently `closed` — these need `bd update` to re-evaluate readiness}
- **`bd compact` candidates:** {manual judgment — list closed-issue count and flag if >150 closed since last compact, otherwise "below threshold"}

Basic Memory graph health (via Basic Memory MCP tools):

1. Run the knowledge-gardener agent for automated audit (orphans, schema, stale notes, duplicates)
2. Validate both schemas: call mcp__basic-memory__schema_validate with note_type="npm_package" and again with note_type="engineering"
3. Call mcp__basic-memory__schema_diff on both types to detect drift (new observation categories in use but not in schema, or schema fields rarely used)
4. If notes cluster around a new unschemaed type, call mcp__basic-memory__schema_infer and consider creating a new schema
5. Verify all notes have: frontmatter type and tags, ## Observations, ## Relations
6. Flag notes missing any layer; fix or create beads issues

Basic Memory notes (project-independent knowledge base): Basic Memory is a cross-project knowledge store — notes there must be written from a general engineering perspective, not referencing project-specific file paths, table names, or project structure. Vendor package names (e.g., @scope/vendor-package) are fine since they're real npm packages. Mentioning this project by name is okay when genuinely relevant — just don't make notes only useful within this project. Call mcp__basic-memory__search_notes and:

• Update notes that have been superseded by new learnings this sprint
• Remove notes that are too project-specific — generalize or delete
• Check for duplicate notes across directories and merge them
• Verify tags are consistent and discoverable

5. Create beads issues from findings

Review the "What could improve" and "Lessons learned" sections for actionable items that aren't already tracked. Create beads issues for each:

bd create "..." -t bug|task|feature|chore -p N --description "..."

(-t = type; -p = priority: 0=critical, 1=high, 2=medium, 3=low, 4=backlog)

Include code quality issues, process improvements, and any findings that need follow-up work. Skip items that are purely observational or already have open issues.

Beads unavailable (Tier C): there is no backlog to file into — instead append a ### Follow-ups (untracked) task list to the RETRO-NN.md file, one checkbox per actionable finding, so the items are still captured:

### Follow-ups (untracked)

- [ ] {finding} — {type}, {priority}

Announce that follow-ups were written to the RETRO file rather than created as beads (they can be filed later if beads is adopted).

Decision capture. When a sprint outcome is a decision (an architectural or product choice with explicit rationale and rejected alternatives) rather than a task, bug, or feature, file it as the decision issue type — not a generic task. Decision-typed issues are queryable as ADRs and follow the supersede workflow.

Recognize a decision when the sprint surfaced any of:

• A choice between two or more viable approaches with rationale recorded
• A reversal or revision of a previous decision (use supersede to link)
• A constraint accepted (e.g., "we will not support X until Y") that future work must respect

For each decision, prompt the user to either:

1. Invoke the upstream /beads:decision slash command — preferred path. The command lives in the upstream beads plugin (NOT vp-beads) and wraps bd create --type=decision with structured templates plus record/list/show/supersede operations. Use this for the full lifecycle.

2. Or create directly via bd create --type=decision with the four-section template:

   ## Decision
   
   ## Rationale
   
   ## Alternatives Considered
   
   ## Affects
   

   The first three are required by validation.on-create=error; ## Affects is conventional and lists impacted components, files, or future work.

Lifecycle: decision-typed issues stay open while the decision is in force. open = active decision, closed = superseded or reversed (NOT closed-on-create). The retrospective never auto-closes decisions — the upstream /beads:decision slash command handles supersession when the decision is later revised. Cross-reference that command for the full lifecycle (record/list/show/supersede) rather than implementing it here.

Beads unavailable (Tier C): record the decision inline in RETRO-NN.md as a ### Decisions block carrying the same four sections, instead of bd create --type=decision:

### Decisions

**{decision title}**

- **Decision:** {the choice made}
- **Rationale:** {why}
- **Alternatives considered:** {rejected options}
- **Affects:** {impacted components, files, or future work}

Announce that the decision was captured in the RETRO file; it can be promoted to a decision-typed bead later if beads is adopted.

6. Knowledge gap audit

Run /knowledge-gaps (if vp-knowledge is installed):

/knowledge-gaps scans all package manifests in the project (npm, Rust crates, Go modules, PHP Composer, Python PyPI, Ruby gems) and tool manifests (Brewfile, GitHub Actions workflows, Dockerfile, VSCode extensions). It cross-references each dependency against Basic Memory notes to identify undocumented packages and tools.

Steps:

1. Run /knowledge-gaps — it handles all manifest types automatically. If vp-knowledge is not installed, skip this step and note in the retrospective under "What could improve" that knowledge gap coverage was not audited.
2. Include Tier 1 gaps in the retrospective under "What could improve"
3. Create beads issues for the top 3 undocumented packages or tools

7. Write project-independent learnings to Basic Memory

Basic Memory is a cross-project knowledge base — it persists across all repositories and sessions. Notes written here must be generalizable engineering knowledge, not project-specific implementation details. Ask: "Would this note help me on a completely different project using the same technology?" If yes, write it. If it only makes sense in the context of this codebase, it belongs in MEMORY.md or the project CLAUDE.md instead.

For each learning, search first, then create or update:

• If no matching note exists: call mcp__basic-memory__write_note to create it
• If a note exists with new content: call mcp__basic-memory__read_note first to get exact content, then call mcp__basic-memory__edit_note with find_replace or replace_section — never call write_note on an existing note (it requires overwrite=True and risks replacing the full note content)

Organize by engineering domain:

Directory	Topics
engineering/fastify/	Plugin patterns, lifecycle, error handling
engineering/frontend/	Web components, CSS, dark mode, SSR, a11y
engineering/database/	Query patterns, migrations, PostgreSQL
engineering/testing/	Test conventions, infrastructure, coverage
engineering/tooling/	Linter config, build pipelines, knip
engineering/agents/	Orchestration, workflow, quality gates

Guidelines:

• Only write notes for patterns confirmed this sprint — not speculative
• Use concrete code examples, not abstract principles
• Tag notes for discoverability
• No project-specific internals — replace project file paths with generic descriptions (e.g., "route handler file" not "lib/routes/settings.js"), omit table names, and describe patterns in terms of the technology, not the application. Referencing vendor packages by npm name (e.g., @scope/vendor-package) is fine — they're real published packages. Mentioning this project by name is okay when genuinely relevant — just don't make the note only useful within this project.
• Division of labor with upstream-tracker and synergy-tracker. This step writes engineering/* notes (patterns, conventions, lessons learned). For upstream friction about specific packages or tools, use /upstream-tracker workflow 6 (Promote to Basic Memory) instead — it writes to the ## Upstream Friction section of entity notes (npm/*, brew/*, etc.), avoiding duplication. For cross-project extraction opportunities tracked in SYNERGY-*.md files, use /synergy-tracker — it manages the extraction lifecycle and any corresponding Basic Memory notes. For packages not yet in Basic Memory, suggest /package-intel or /tool-intel for enrichment first. NEVER write to engineering/agents/vp-plugins-* paths from this step — those are sibling-relationship notes owned by /synergy-tracker workflow 5 (Promote to Basic Memory). For cross-project lessons that touch a sibling-relationship, log via /synergy-tracker workflow 1 (Log a synergy entry) and let workflow 5 (Promote to Basic Memory) promote them; do not shortcut the relationship-note ownership boundary by writing engineering/agents/vp-plugins-* directly here.

8. Suggest documentation updates

After writing the retro, suggest updates to:

• Project CLAUDE.md — new conventions, gotchas, or commands discovered
• MEMORY.md — stable patterns confirmed across sprints
• README.md — if project structure or commands changed

Present suggestions to the user for approval before editing.
