feature-ideation

name	feature-ideation
description	Generate prioritized feature recommendations for an app from reviews + competitor evidence. Use when the user wants feature ideas, product roadmap input, or "跑功能策划" for a specific app.

Feature Ideation Workflow v3

This skill is the single authoritative reference for the feature ideation flow. Re-read it before every run. v3: removed mechanical review bucketing (rating thresholds + trigger-word list) and removed the direct AppMate RAG dependency. The LLM now classifies each raw review on its own; competitors come from the competitor-research skill's output. v2 had been the prior "negative + wishlist buckets + RAG seed" design.

Step 0 — Prerequisites

0.1 Credentials gate

Every step in this skill calls App Store Connect APIs. Before any other step, run:

python3 scripts/appmate_config.py check

If exit code ≠ 0, STOP. Do not invoke any other part of this skill, do not run scripts/feature_ideate.py. Tell the user AppMate credentials are not configured, show the precheck output verbatim, and tell them to invoke the appmate-setup skill. The downstream script also enforces this gate (exits 2 with the same message).

0.2 Competitor data: auto-chain the competitor-research skill if missing

This workflow consumes data/competitors_<slug>.json, the final artifact produced by the competitor-research skill (invoked for the same <app>). Both skills compute slug via slugify(canonical_app_name, market), so passing the same app argument to both guarantees the slug matches.

Decision rule — before invoking feature_ideate.py:

1. Resolve the canonical app + market for <app> (read data/apps_full.json, call find_app(<arg>) → name, then pick main market via the largest 30-day downloads in sales_cache.json with the same fallbacks the script uses — primaryLocale, then US). Compute expected = data/competitors_<slugify(name, market)>.json.
2. Check whether expected exists.
3. If it does not exist, invoke the competitor-research skill end-to-end for the same <app> argument first — all three stages: Stage 1 script analyze, Stage 2 LLM tokenization, Stage 3 LLM relevance pass + final-JSON + markdown write. Paste the rivals markdown back into the conversation per that skill's own rules. Then return here and proceed to Step 1 of feature-ideation. The user gets two reports out of one ask: rivals first, then features. That is intentional — both are useful, and the rivals card is also the new evidence basis for feature ideas.
4. If it exists, proceed directly. Optionally check competitors_generated_at; if it is > 30 days old, mention staleness when delivering the final feature report (do not auto-refresh unless the user asks).

No RAG fallback. No placeholder competitors. The only two paths are: the cached file, or a fresh competitor-research skill run. The earlier (v2) direct appmate_rag_client.search(...) call is gone for good — competitor evidence is unified through the competitor-research flow so the two workflows stay coherent.

Safety net: feature_ideate.py still exits 2 with competitors JSON not found if the file is missing at script-execution time. This catches the case where the script was invoked outside the skill (cron, manual CLI). When it fires, treat it the same way — invoke competitor-research for the same app, then re-run.

One-line summary

Given a live app → the script aggregates raw reviews (last 90 days, ≤ 150) plus the kept competitors from competitors_<slug>.json → the LLM reads each review and classifies it itself (complaint / suggestion / praise), then scores ideas internally on 4 dimensions → a markdown report with two sentences per feature (what it is + why), with no scores shown.

Input / Output / Trigger

Item	Content
Trigger	the user says "run feature ideation for <app>"
Input	data/apps_full.json (reviews) + data/competitors_<slug>.json (from the competitor-research skill — auto-chained on first run for an app, then cached)
Output	data/phase_a_feature_<slug>.json (intermediate) + data/feature_ideas_<slug>.md (final) + Claude pastes the full markdown back into the conversation
Intervention points	2 (trigger + receive); optional follow-up "detail one of the ideas"

Workflow overview (3 steps)

1. Step 1 · Script pre-aggregation (feature_ideate.py) — app fuzzy match (reuses aso_optimize_v2) → pull raw reviews from last 90 days (≤ 150, no filter) → load competitors from data/competitors_<slug>.json (Claude should have already auto-chained the competitor-research skill per §0.2 if the file was missing; script exits 2 as a safety net otherwise) → data/phase_a_feature_<slug>.json.
2. Step 2 · LLM idea generation (Claude, conversation layer) — read each raw review, decide whether it is a complaint, a suggestion, a praise, or noise; brainstorm 15-20 candidates (5× principle); score each on 4 dimensions (internal only); anti-junk filter (4 hard rules); sort by composite score descending, take the top 5-10.
3. Step 3 · Render + deliver (Claude) — two sentences per item (what it is + why); arrange by composite score descending but do not show scores; save data/feature_ideas_<slug>.md; paste the full markdown back into the conversation.

Step 1 · Script pre-aggregation (decision rules)

1a. App anchoring

Reuses aso_optimize_v2.find_app() — accepts App Store ID / bundle ID / SKU / fuzzy name match.

Main-market selection:

1. Preferred: the country with the largest 30-day downloads (read data/sales_cache.json).
2. Fallback: the country corresponding to the app's primaryLocale.
3. Extreme fallback: US (so the script does not crash).

1b. Raw reviews collector

collect_raw_reviews() does the bare minimum — no rating threshold, no trigger-word list, no semantic split. The LLM in Step 2 reads each body and decides what it is.

Rule	Value
Age cutoff	last 90 days (createdDate ≥ today − 90)
Cap	first 150 entries after newest-first sort
Per-entry schema	{rating, title, body, locale, created_at} (body is Apple's original field name)
Cross-language	no language filter — reviews in all locales pass through; the LLM handles translation

v2 → v3 change: v2 had two pre-computed buckets — reviews_negative (rating ≤ 3 + body ≥ 10 chars) and reviews_wishlist (rating ≥ 4 + a trigger word from a hardcoded list). Both were leaky: rating ∈ {4, 5} entries often carried strong suggestions, low-rating entries were sometimes just venting with nothing actionable, and the trigger-word list missed many real signals. v3 sends raw reviews and lets the LLM do the semantic call.

1c. Competitor loader (no RAG)

load_competitors(app_name, market) reads OUTPUT_DIR / f"competitors_{slugify(app_name, market)}.json". The file is the final artifact of the competitor-research skill (see skills/competitor-research/SKILL.md). Per §0.2, Claude should ensure this file exists before invoking the script — by auto-chaining that skill when it's missing.

Step	Behavior
File missing	return None → build_phase_a returns None → main() prints a safety-net message pointing at the competitor-research skill and exits 2. Normally never fires when the skill flow was followed; fires if the script was invoked directly.
File present	read payload["filtered"] (already top-10 by threat_score, already passed the LLM relevance pass) and copy these fields per entry: name, description_short, outranked_keywords, relevance_reason, threat_score, rating, review_count
Stale data	the script does not check generated_at freshness; it surfaces the timestamp in phase_a so the LLM can flag staleness in the report if it looks old (> 30 days)

v2 → v3 change: v2 called appmate_rag_client.search(query=seed, region=market, top_k=10, ...) directly with a seed-word it picked from the app's name. The seed-extraction was fragile (compound brand names like 便签Pro lost their context, English-only app fallback returned useless rivals), and the RAG result was a different shape than the SERP-overlap rivals produced by the competitor-research skill. v3 reuses the already-curated, already-LLM-filtered result of that skill, so the two workflows produce a coherent picture of the same competitive landscape.

1d. phase_a JSON shape

{
  "app": "<name>",
  "app_id": "<id>",
  "bundle_id": "<bid>",
  "market": "<country>",
  "downloads_30d_in_market": 1300,
  "generated_at": "2026-05-13T...",
  "reviews": [
    {"rating": 2, "title": "", "body": "...", "locale": "CHN", "created_at": "2026-05-05T..."},
    {"rating": 5, "title": "", "body": "希望加...", "locale": "CHN", "created_at": "..."}
  ],
  "competitors_source": "<absolute path to competitors_<slug>.json>",
  "competitors_generated_at": "<timestamp from competitors_<slug>.json>",
  "competitors": [
    {"name": "...", "description_short": "...", "outranked_keywords": ["..."],
     "relevance_reason": "...", "threat_score": 42, "rating": 4.7, "review_count": 1234}
  ]
}

Step 2 · LLM idea generation (decision rules)

2a. Read + classify reviews first (new in v3)

Before brainstorming, walk the reviews[] array once. For each entry decide which bin it falls into — no fixed rating rules, use the body content:

Bin	Looks like
Complaint	crash report, sync loss, billing dispute, broken core flow, uninstall warning
Suggestion	"希望加 X / would love Y / 能否 / please add / 不能 X / 为什么没有 Y / I wish" — explicit feature ask
Praise + hidden signal	rating ≥ 4 but the body mentions a workflow they wish was smoother, or a competitor they prefer for one feature
Noise	spammy / "good" / non-actionable rating-only entry — ignore

You may discount or skip noise; this is not a "first 50" cap. A rating ∈ {4, 5} body that contains a strong suggestion still goes into the suggestion bin — do not anchor on the star count.

2b. The 5× principle

Brainstorm 15-20 candidates internally, pulling 15-20 from the two evidence sources (your bins from §2a + competitors), then cross-dedup → trim to 5-10 finalists by composite score. Rationale: experience says the candidate count should be 5× the finalist count for comparative filtering to be meaningful.

2c. The 4-dimension scoring formula (internal rule — never shown to the user)

The following is the LLM's internal ranking methodology (based on RICE). The final markdown output does not show scores — items are only arranged from high to low score; the user sees only a sorted feature list.

Each candidate is scored 1-5 on 4 dimensions:

Internal dimension	1-5 scoring basis
Reach	reviews mention ≥ 10 → 5; validated by multiple competitors → 4; single evidence → 2
Impact	solves a payment blocker / prevents uninstall → 5; improves retention → 4; experience detail → 2
Confidence	reviews ≥ 3 + competitor validation → 5; single source only → 2; pure speculation → 1
Effort	macOS solo dev: half a day → 1; 2+ weeks → 5

Composite score = (R × I × C) / E (range 0.2 - 125, for LLM internal ranking only).

2d. Anti-junk — 4 hard rules

Rule	Application
❌ Single evidence	Confidence ≤ 2 AND Reach ≤ 2 → cut directly
❌ Platform violation	a mac app proposing "add GPS / push / an iOS-only sensor" → delete
❌ Vague words	"improve performance / nicer / smarter" → must be specific to a behavior
❌ Rename-style non-action	"rename a button" must state "which interaction changed"

2e. Sort and trim

• Sort by composite score, high to low.
• Take the top 5-10 as finalists.
• Main list < 5 → add a ⚠️ "insufficient evidence, suggest adding more reviews or expanding the competitor pool with the competitor-research skill" warning at the top.

Step 3 · Render + deliver

3.1 Output template (what the user finally sees)

Core rules:

1. Do not show any scores (composite score, 4-dimension scores all hidden) — scores are only the LLM's internal ranking basis.
2. No jargon: RICE / R / I / C / E / Reach / Impact / Confidence / Effort / Explore / Exploit / Core value / Onboarding / Delight.
3. Two sentences per item only: the first says "what it is / how it interacts", the second says "why do it / what the evidence is".
4. Arrange by composite score high to low (but do not show the score).

Rendered in the same language the user has been using in this conversation. Default to English; if the user has been writing in Chinese / Japanese / Spanish / etc., translate the template headers, labels and prose accordingly. App Store metadata strings (title / subtitle / keywords / competitor app names) must remain in the App Store's source locale (e.g. zh-Hans names stay zh-Hans) — only the surrounding explanation follows the user's conversation language.

The template below is written with English placeholders. Substitute the equivalent words in the user's conversation language when rendering.

# 🚀 <App name> · Feature recommendations

> ⚠️ <evidence-thin warning — only shown when total reviews < 10 OR total competitors == 0. Example: "Evidence thin: only 7 reviews + 0 competitors. Recommend running the competitor-research skill first to add competitor evidence, then revisit this report.">

**1. <Feature title>** — <one sentence: what the feature is, how it interacts>. <one sentence: why do it, what's the evidence>.

**2. <Feature title>** — <same structure>.

... (5-10 items total) ...

**N. <Feature title>** — <same structure>.

---

**Top N**: #X / #Y / #Z — short summary of each item's core value (one sentence each).

Want one expanded? Tell me the number and I can help you write a mini PRD (user stories / acceptance criteria / sprint breakdown).

3.2 6 layout rules

1. No jargon: the user-visible content must not contain RICE / Reach / Impact / Confidence / Effort / Explore / Exploit / Core value / Onboarding / Delight — always use plain prose in the user's conversation language.
2. No score numbers: do not show the composite score or any of the 4-dimension scores.
3. Two sentences per item: first "what it is", second "why". The two sentences are separated by a period (use the punctuation natural to the user's conversation language — e.g. full-width 。 for Chinese, . for English).
4. Bold feature title: **N. Title** followed by — (em dash, full-width when the surrounding text is CJK).
5. Top evidence warning: when reviews total < 10 or competitors total == 0, the warning must show.
6. Closing "Top N" + "Want one expanded": guide the user to follow up (translated to the user's conversation language).

File structure

File	Purpose
scripts/feature_ideate.py	Step 1 script (runs by app name; hard-depends on data/competitors_<slug>.json)
data/phase_a_feature_<slug>.json	intermediate artifact (overwritten each run)
data/feature_ideas_<slug>.md	final deliverable (overwritten each run)

Connection to existing workflows

Direction	Content
Upstream auto-chain	data/apps_full.json + data/competitors_<slug>.json. When the competitors file is missing, this skill first invokes the competitor-research skill for <app> end-to-end (rivals markdown gets pasted back as a side effect), then continues.
Side-chain trigger	the aso-daily-report skill finds an app's rank dropping out → trigger this flow to find new features as a fix
Downstream upgrade (v4)	add a feature_detail_<slug>.py to expand a single idea into a PRD

CLI

# from the plugin repo root

# Step 0 prerequisite (one-time per app, also refresh whenever the SERP shifts):
python3 scripts/competitor_research.py analyze "<app>"
# ...then Claude tokenizes + the rank pass + Claude writes data/competitors_<slug>.json
# (handled by the competitor-research skill end-to-end)

# Step 1: aggregate reviews + competitors → phase_a JSON
python3 scripts/feature_ideate.py "<app>"

# the app argument accepts: App Store ID / bundle ID / SKU / fuzzy name match
# examples:
#   python3 scripts/feature_ideate.py "Sticky Note Pro"
#   python3 scripts/feature_ideate.py "com.fengyiqi.PostItnoteForMac"
#   python3 scripts/feature_ideate.py "1482080766"

# Steps 2-3: Claude reads the phase_a JSON and generates + renders per §2 / §3 rules

If feature_ideate.py exits 2 with competitors JSON not found, that is the safety net firing — invoke the competitor-research skill for <app> end-to-end, then re-run this command. (In normal skill-driven runs you should not hit this, because §0.2 instructs Claude to auto-chain that skill when the file is missing, before ever invoking the script.)

Known limits

• Reviews mix languages; LLM classification may be off on idiomatic phrasing (taking the most recent 90 days lowers the risk).
• The competitor list reflects whenever the competitor-research skill was last run for this app — staleness shows up in competitors_generated_at; if it's > 30 days old, suggest re-running the prereq before trusting the report.
• The composite score is fairly subjective; running the same app multiple times varies ±20% (suggest taking the union).
• Apps with ≤ 5 reviews struggle to produce reliable ideas (the first run warns "insufficient evidence").
• v3 dropped the direct AppMate RAG call → no more "blind" same-keyword similar apps; the trade-off is a sharper, already-LLM-curated competitor set from the SERP-overlap path.
