cleanup(engineering): address remaining 7 polish items from PR #718 bot review
Bundle of low-medium-severity follow-ups that were deferred when PR #720
landed the 3 blocking bugs. None of these silently break correctness —
they're discoverability, consistency, and convention gaps.

Bugs / code-quality:

1. fullstack_decision_engine.py: asymmetric cadence matching
   `inputs.cadence in target or target in inputs.cadence` produced
   asymmetric results — "per-pr" matched "per-pr-with-gates" but not
   vice versa. Profile cadences are intentional alternatives joined
   by "-or-" (e.g. "weekly-or-on-demand" → {weekly, on-demand}); now
   parsed explicitly with "-with-..." modifier suffixes stripped.

   Verified:
     cadence=per-pr → matches per-pr, per-pr-with-gates, daily-or-per-pr
     cadence=daily  → matches daily-or-per-pr (only)
     cadence=on-demand → matches weekly-or-on-demand

2. fullstack_decision_engine.py: rename weight_total/weight_matched
   to w_total/w_matched. Backend and frontend engines already use the
   short form; this aligns the three files as a family.

3. sync-gemini-skills.py: 3-way name collision in dedup logic
   The naive `if name in seen_names: name = parent-name` handled one
   collision but not two. Three "status" skills under "skills" parent
   dirs produced two entries both named "skills-status". Now suffixes
   with -2, -3, ... so each entry has a unique index name. Eliminates
   the duplicate-name ambiguity surfaced when checking PR #713.

Discoverability:

4. senior-fullstack/SKILL.md: surface fullstack_decision_engine.py in
   the labeled "Tools" section at the top. Previously only mentioned
   inline in the body (5 references buried in the Stack Decision Matrix
   section); not findable when scanning the SKILL.md.

Conventions / v2.8.0 compliance:

5. commands/cs-{fullstack,backend,frontend}-review.md: add explicit
   "## Forcing-question library" section header per the v2.8.0
   convention. Each lists the 7 questions inline with a pointer to
   the canonical reference file.

6. agents/engineering/cs-{fullstack,backend,frontend}-engineer.md:
   alphabetize the specialist list in the description field (annotated
   that workflow body order remains dependency-driven). Makes the
   three agent descriptions consistent as a family.

7. agents/engineering/cs-{backend,frontend}-engineer.md: promote the
   "Cross-agent invocation" content out of Workflow 3 into a dedicated
   "## When invoked as fork target" section with an explicit question-
   skip table per parent agent (cs-fullstack-engineer, cs-cto-advisor,
   cs-vpe-advisor, cs-ciso-advisor for backend; cs-fullstack-engineer,
   cs-content-creator, cs-product-manager for frontend). Closes the
   cross-agent contract gap the bot flagged.

Not changed:

- CLAUDE.md plugin-schema section (already corrected in #715; bot's
  "stale text" claim was incorrect — it was reading the cumulative diff)
- Workflow body specialist order (intentional dependency order; would
  break the SLO-first → API → DB → migration → observability sequence)

Verification:
- All 3 decision engines: --sample → exit 0
- Cadence matching: 3 test cases pass cleanly
- check_plugin_json.py --all → 0 FAIL, 0 WARN, 69 OK
- sync-gemini-skills.py → 392 unique names (was 391 unique / 1 dupe)

description: Fullstack engineering review — walks the 7 Matt Pocock forcing questions, picks the profile, forks into POWERFUL specialists (api-design-reviewer, database-designer, slo-architect). Invokes the cs-fullstack-engineer agent with context fork.

# /cs:fullstack-review — Fullstack engineering review
Use the `cs-fullstack-engineer` agent (which uses `context: fork` to keep the parent thread clean) to handle this inquiry:
**$ARGUMENTS**
## Forcing-question library
Canonical source: `engineering-team/skills/senior-fullstack/references/forcing_questions.md` (7 questions, one-per-turn, recommendation + canon citation per question).
1. Team size now + 12-month headcount
2. Deployment cadence (per-PR / daily / weekly / quarterly)
3. Customer-facing / internal tool / marketing site
4. One-year p50 + p99 traffic forecast
5. Hiring-against vs training-into the stack
6. Year-one monthly cloud + SaaS budget ceiling
7. Three verifiable success criteria with numeric targets
## Routing protocol
1. **Walk the 7 forcing questions** in `engineering-team/skills/senior-fullstack/references/forcing_questions.md`. One per turn. Recommend the answer with cited canon. Track in `/tmp/fullstack-grill-<date>.md`.
2. **Surface kill criteria** — if any question trips one (e.g., "microservices day 1, team size 3"), STOP and resolve before proceeding.
3. **Run the deterministic profile picker:**
```bash
python engineering-team/skills/senior-fullstack/scripts/fullstack_decision_engine.py \
--team-size <N> --team-size-12mo <N12> --cadence <c> \
--user-facing <true|false> --budget <USD/mo> \
--traffic-p99-rps <N> --data-sensitivity <tier>
```
4. **Surface the matched profile + runner-up tradeoff** (if within 15%).
5. **Fork into specialists** (one at a time, depth-first):
- `api-design-reviewer` for API contract
- `database-designer` for schema
- `slo-architect` for reliability target
- `ci-cd-pipeline-builder` for the pipeline
- `performance-profiler` for perf baseline
- `cs-karpathy-reviewer` before any commit
## Output expectations (≤ 200-word digest)
- Matched profile + reason
- Three verifiable success criteria with numeric targets
- Named approver chain
- List of specialists invoked + artifact paths
- Recommended next sub-skill (if any)
## Anti-patterns
- ❌ Bundling forcing questions — one per turn.
- ❌ Skipping the kill-criteria check.
- ❌ Reimplementing specialist scope. Fork — don't duplicate.
- ❌ Auto-approving production changes. Always name the human approver.
## Customization
Profiles live at `engineering-team/skills/senior-fullstack/profiles/`. To customize for your org:
1. Copy `saas-startup.json` (or whichever best fits) to `<your-org>.json`.
2. Edit `constraints`, `stack_recommendations`, `success_thresholds`, `named_approver_chain`.
3. The decision engine auto-discovers new profile JSONs.
