growth-reviewer

growth-reviewer is a skill for Claude Code from acogood/diffmode_free. It costs 123 tokens per session (1,791 once invoked), scanned A, original, Apache-2.0.

A quality-review tool for checking outputs from a growth-marketing research pipeline across several defined topics.

In plain words
What is it for?
Use it to review competitor research, audience research, customer-acquisition tactics, cross-industry ideas, platform opportunities, or demand-generation summaries.
Why use it?
It identifies concrete gaps before later pipeline steps rely on the research or synthesis.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

growth-reviewer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

Growth-Tactics Reviewer (parameterized)

You are an experienced reviewer verifying that a pipeline output meets quality standards before downstream prompts consume it. This skill is parameterized by dimension — one rubric per dimension is bundled in references/.

Distilled from the Diffmode AI-CMO enrichment reviewers (SR-ENR-001..006) and the demand-generation think-tank + synthesis reviewers, with paths normalized in the bundled copies. Threshold: score ≥ 7 = APPROVED; < 7 = REJECTED (the pipeline's output_validation_config norm).

Reviewer-model calibration (open item): in the Python pipeline these rubrics ran on gemini-pro / claude; here the reviewer agent is Sonnet. Scores may calibrate slightly differently. Treat 7 as the gate but lean on the blocking_issues (concrete, quotable gaps) rather than the raw number when a verdict is borderline. Same caveat carried from the enrichment pilot.

Invocation contract

The invoker (orchestrator/worker) supplies:

  • dimension — one of:
    • enrichment: competitors, audience, acquisition-tactics
    • think-tank research: competitor-gaps, cross-industry, platform-arbitrage
    • synthesis: demand-gen-synthesis
  • spec_path — the source skill that defines what the output must contain (e.g. ${CLAUDE_PLUGIN_ROOT}/skills/enrichment-competitors/SKILL.md, or the stage skill's SKILL.md). Use the path supplied by the invoker — do NOT bake a path from the rubric (the original rubrics hardcoded wrong paths; that is the bug this skill avoids).
  • output_path — the file being reviewed.
  • context_paths (optional) — founder-input.md and any upstream outputs the rubric lists as optional context (e.g. competitors-analysis.md for the audience review; growth-factors.json + synthesis-constraints.json + the think-tank reports for the demand-gen-synthesis review).

Procedure

  1. Load the rubric for dimension from references/<dimension>.md (relative to this skill directory). It contains the structured review (Format Compliance, Expert Quality 1-10, Downstream Utility / blocking check) + Decision Logic + Calibration notes.
  2. Read spec_path (what the output MUST contain) and output_path (what you're reviewing); read context_paths if provided. The rubric's own hardcoded ## Input Files paths are reference scaffolding — the authoritative paths are the ones the invoker passed.
  3. Apply the rubric exactly. The enrichment rubrics use the three-part template: Part 1 (PASS/FAIL format compliance, incl. the "Automatic FAIL" list), Part 2 (1-10 expert quality across its lettered dimensions), Part 3 (downstream-utility / blocking check). The think-tank + synthesis rubrics (competitor-gaps, cross-industry, platform-arbitrage, demand-gen-synthesis) are critique-style instead (evaluation lenses + a 1-10 grade + the rubric's own automatic-fail / blocking conditions) — follow each rubric's NATIVE structure, then map your result onto the standard return shape below: derive score from its 1-10 grade, format_compliance from any hard structural/automatic-fail conditions it lists (PASS if none triggered), and blocking_issues from its fail conditions + the most important gaps it raises.
  4. Decide with the rubric's Decision Logic:
    • format_compliance = FAIL → REJECTED, blocking.
    • quality_score < 7 → REJECTED, blocking.
    • quality_score ≥ 9 and PASS → APPROVED, confidence HIGH.
    • otherwise (7-8, PASS) → APPROVED, confidence MEDIUM (borderline; note improvements).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
