Diamond Assess

6b. Check metric snapshot freshness (v0.14; L0/L1/L2/L5 only):

• If the current diamond scale is L0, L1, L2, or L5 AND .claude/jit-tooling/active-metrics.yml exists:
  • For each status: active source, find the newest file in .claude/evals/metrics/<source>/.
  • If the newest snapshot is >7 days old (or missing entirely), flag as a warning and recommend /metrics-pull.
  • If active-metrics.yml is missing, recommend /metrics-detect (softer — info-level, not a gate).
• Rationale: evidence loops for Purpose/Strategy/Opportunity/Market depend on external signal freshness. A stale snapshot silently anchors confidence.
• Do NOT block progression on stale snapshots — this is a NUDGE, not a gate.

7. Check corrections.md:
   • Any relevant past mistakes to avoid?

7b. Check trio perspective coverage (Torres Product Trio):

• For the current diamond phase, verify all three perspectives (product/design/engineering) have been applied.
• Reference engine/theory-gates.md §Trio Perspective Requirement for the per-scale coverage matrix.
• Flag any missing perspectives as a gap: "Design perspective not yet applied at L[X]. Consider running /usability-check or /service-check."
• If perspectives are in conflict, recommend engine/perspective-resolution.md.

8. Coaching check (Rother's Coaching Kata): Surface these five questions in the output to prompt the human's thinking:

   1. What is the target condition for this diamond? (What does "done" look like?)
   2. What is the actual condition right now? (Summarize from steps 2-7 above)
   3. What obstacles are preventing progress? Which one are you addressing now?
   4. What is your next step? What do you expect will happen? (Force a prediction before acting)
   5. When can we check what we learned from that step? (Commit to a review point) The coach (human) should answer these, not the agent. The agent surfaces them. Source: Rother (Toyota Kata) — the 5 questions install scientific thinking as a daily habit.

9. Log assessment in decision-log.md (MANDATORY):

   • APPEND a ### Diamond Assessment entry to harness/decision-log.md
   • Include: diamond ID and scale, gates passed/failed, current confidence with rationale, evidence gaps
   • This log entry is essential for auditability — every assessment should be documented

10. Recommend next action:

• If all gates pass and confidence meets threshold: recommend transition to next phase
• If gates fail: recommend specific actions to address failures
• If confidence is low: recommend evidence-gathering activities
• If anti-patterns detected: recommend corrective actions
• If regression needed: recommend which phase to return to and why

11. Play devil's advocate: Before recommending progression, ask:

    • What are we most likely wrong about?
    • What evidence have we dismissed?
    • Is there a simpler path we're overlooking?

12. Report harness thickness (informational):

    • Count: total skills, active guardrails, mandatory reads, hooks, theory gates
    • Current: 44 skills, 32 guardrails, 4 mandatory reads, 5 hook layers, 12 gates
    • If thickness has increased since last assess, note it
    • This is observability, not a gate — purely informational
    • Source: Trivedy (Anatomy of an Agent Harness, LangChain blog — "scaffolding should decrease as models improve," but harnesses remain valuable as they engineer systems around model intelligence)

Output Format

ALWAYS output in plain language first, then technical details. Use .claude/engine/status-translations.md for translations.

ALWAYS render the journey map first. Follow .claude/engine/wayfinding.md to render the "You Are Here" map before any other output. This orients the user to where they are in the full L0→L5 progression before diving into gate details.

[Journey map from wayfinding.md — rendered first]

## Where We Are

Current focus: [plain-language description from status-translations.md]
  [1-2 sentences of context]
  Confidence: [plain word] ([number], [Gilad level]) -- [why this level, what would increase it]

## Progress

[N] of [M] diamonds complete:
  [Name]: [STATUS] -- [plain-language one-liner]
  [Name]: [STATUS] -- [plain-language one-liner]

## Theory Gate Check (for next transition)

| Gate | Status | Suggested Skill |
|------|--------|----------------|
| Evidence | Pass/Fail | /user-interview or /assumption-test |
| Four Risks | Pass/Fail | /assumption-test |
| ... | ... | ... |

## What I'd Challenge (Devil's Advocate)
- [Key assumption to question]
- [Evidence gap to flag]

## Coaching Check (for the human)
1. What does "done" look like for this diamond?
2. Given what we know now, what's the biggest obstacle?
3. What's your next step -- and what do you expect will happen?
4. When should we check what we learned?

## Recommended Next Step
[Plain-language recommendation with theory justification]

Suggested actions:
  - /skill-name -- [why this is relevant now]
  - /skill-name -- [why this is relevant now]
