evaluate-ad

name	evaluate-ad
description	Score a launched paid ad (Meta, Google, TikTok, LinkedIn) from real metrics — network-specific primary metric + diagnosis + fatigue/auction signals — inside an existing eval loop. One cycle per network. Not for loop setup (use run-pipeline), writing new creative (use write-ad), channel-mix retrospectives (use plan-campaign), or campaign-level scoring (use evaluate-campaign).

Ad Eval — Orchestrator

Evaluation skill. Converts launched paid-ad evidence into a cycle snapshot + ledger row + narrowly-scoped next action inside an existing eval loop. One cycle = one network (+ audience-temp on Meta/TikTok).

Core Question: "Did this ad cycle, on this network, create measurable signal strong enough to keep / discard / watch / block — and what should the next strategy/execution skill know?"

Why, methodology, history: references/playbook.md [PLAYBOOK]. Capability metadata (route triggers, prerequisites, load map): routing.yaml.

Critical Gates

1. Existing eval loop required. program.md + context.md absent → NEEDS_CONTEXT, recommend /run-pipeline. This skill does not create loops.
2. Measurement evidence required + the NETWORK's primary metric decides the row. Need ≥1 metric source, window, current value for the network's primary metric — Meta CTR/CPA/ROAS, Google Quality Score + impression share, TikTok thumbstop/hold rate, LinkedIn cost-per-qualified-lead — per the loaded metric surface (references/ad-intelligence/{google-ads,tiktok-ads,linkedin-ads}-metrics.md; Meta is inline). Secondary metrics explain diagnosis; don't override unless program.md defines a guardrail failure.
3. One network per cycle (+ one audience-temp on Meta/TikTok). Networks (and Meta cold/retargeting) evaluated in separate cycles. Mirrors write-ad's one-network-per-artifact. Mixed-network/audience metrics → split before ingest or return BLOCKED.
4. No fabricated analytics. Unknown stays unknown. Manual notes only when labeled operator-supplied + tied to date/window/source.
5. Attribution confidence must be explicit. Every verdict includes sample size (impressions + spend window), baseline comparability, confounders (creative change mid-flight, audience shift, iOS attribution gap), confidence: high | medium | low | blocked.
6. Evaluation does not generate creative. Recommend next changes; route creative authorship to write-ad (revised brief), channel-mix to plan-campaign, LP-bottleneck to brief-landing-page.

Responsibility Split

/run-pipeline owns loop setup + program.md / context.md / results.tsv schema + durable learnings. This skill owns post-launch Meta-ad evidence snapshots for a loop cycle, scoped to a single audience-temp. /write-ad owns next-cycle creative.

Inputs

Required: loop slug/path · network (meta | google-ads | tiktok-ads | linkedin-ads) · audience-temp tag (Meta/TikTok: cold-traffic OR retargeting) · source ad-copy artifact (docs/forsvn/artifacts/marketing/write-ad/[audience-temp]-[date]-[slug].md) · measurement window · the network's primary metric value + source · spend window.

Recommended: baseline/prior cycle row · frequency at window close (Creative-Fatigue scoring) · conversion count + CPA · audience size + reach · guardrails from program.md · qualitative evidence (comments, sentiment, click-quality).

Outputs

.forsvn/loops/[slug]/evals/YYYY-MM-DD-cycle-N.md + append one row to results.tsv via bun scripts/append-loop-result.ts (8-col helper) + update learnings.md ONLY for high-confidence keep/discard reusable lessons (critic-gated) + run bun scripts/manifest-sync.ts.

Agent Manifest + Dispatch

4 sub-agents: Layer 1 parallel (Metric Ingest + Diagnosis) → Layer 2 (Recommendation) → Layer 3 (Critic). Critic FAIL → revise once; still FAIL → no ledger row + BLOCKED. Full agent table + per-layer dispatch + 7-dim rubric: references/agent-manifest.md. Domain rubric: references/rubric.md. Shared frame: _shared/evaluation-loop-rubric.md.

Pre-Dispatch

Canonical: _shared/pre-dispatch-protocol.md + _shared/eval-loop-spec.md. Hard-blocks (BEFORE Cold Start): missing program.md/context.md → NEEDS_CONTEXT + /run-pipeline; no measurement evidence → BLOCKED; mixed-audience metrics with no clean split → BLOCKED; custom 10+ col results.tsv → warn + hand-edit. Cold Start: 6 bundled questions (loop · audience-temp · source ad-copy path · window · primary metric value/baseline · spend window). Full read-order + warm/cold templates + --fast behavior: references/procedures/pre-dispatch.md [PROCEDURE]. Session execution profile (single-vs-multi): inherit per references/_shared/execution-policy.md.

Artifact Contract

• Path: .forsvn/loops/[slug]/evals/YYYY-MM-DD-cycle-N.md. Lifecycle: evaluation.
• Frontmatter (10 fields): skill / version / date / status / summary / purpose / lifecycle / use_when / do_not_use_when / upstream / downstream + provenance (input_artifacts = source ad-copy + brand/BRAND.md + research/icp-research.md; output_eval: null — eval cycles are typically terminal).
• Body sections (8): Title · Verdict · Evidence (6-col table) · What Changed This Cycle · Diagnosis (Likely Drivers + Confounders + Creative-Fatigue Signals) · Next Cycle Recommendation · Results Row (8-col TSV) · Learning Promotion. Verdict block must name the audience-temp (Gate 3); Evidence table scopes metrics to that audience-temp.
• Results Row (8 cols): cycle date artifact primary_metric value baseline status description. status ∈ keep|discard|watch|blocked (Critic Hard Fail otherwise); description includes the audience-temp tag.
• Cross-stack contract: consumed by future ad-eval cycles (trend analysis) + write-ad --rev=N+1 (hypothesis seeding) + human reviewers. Ad-eval does NOT directly consume write-ad output — sibling coordination is at the eval-loop boundary. Schema changes require atomic update across _shared/eval-loop-spec.md + downstream callers.

Full byte-identical template + Evidence/Results/Learning formats + helper invocation: references/format-conventions.md [PROCEDURE].

Results Row Helper

bun scripts/append-loop-result.ts "<loop slug>" \
  --artifact evals/YYYY-MM-DD-cycle-N.md \
  --metric "<primary metric>" --value "<current>" --baseline "<baseline>" \
  --status "<keep|discard|watch|blocked>" --description "<one sentence — include audience-temp>"

Do not append on Critic FAIL — return BLOCKED instead.

Critic Override Protocol

Operator ships despite critic FAIL — log BEFORE writing artifact or ledger row: bun scripts/log-critic-override.ts --skill evaluate-ad …. Three overrides → rubric-revision escalation. An override never promotes a contested cycle to keep; a no-override FAIL still returns BLOCKED. Full protocol: references/_shared/critic-override-protocol.md [PROCEDURE].

Anti-Patterns

references/anti-patterns.md [ANTI-PATTERN] — 7 ad-eval rows + 4 cross-cutting marketing-stack. Most common: mixed-audience contamination (Gate 3 + Critic "Audience-Temp Fidelity"), confidence inflation on low-spend (Gate 5 + Critic "Attribution Honesty"), scope drift to write-ad (Gate 6 + Critic "Decision Discipline"), missing source ad-copy artifact (Critic Hard Fail).

Worked Example

Ad-eval cold-traffic cycle (creative-fatigue keep→watch, critic PASS): references/examples/ad-eval-cycle-walkthrough.md.

Durable Rules (protected)

Completion Status

• DONE — eval artifact written, ledger row appended, critic PASS.
• DONE_WITH_CONCERNS — artifact + row written, but confidence low/medium or confounders material.
• NEEDS_CONTEXT — missing loop, source ad-copy artifact, audience-temp tag, or required metric evidence.
• BLOCKED — contradictory data, mixed-audience ingest, filesystem failure, or critic failed after revision.
