## Identity
- platform: x
- handle: ai_dx_tsubota
- platform_url: https://twitter.com/ai_dx_tsubota
- website: https://lin.ee/N1Y3Q16
- entity_type: creator
- person_id: Cross-platform identity not resolved for this creator.

## Reach
- followers: 1360
- following: 203
- posts_total: 1517
- posts_observed: 1
- posts_per_day: 0.841
- account_age_days: 1804
- verified: true
- size_tier: nano

## Engagement
- status: peak_post_only
- peak_post_engagement_rate: 0.00147
- best_post_interactions: 2
- measurement_source: x_post_interactions
- measurement_formula: interactions on one post — likes, or likes + reposts + replies depending on the discovery path (the two are not distinguishable in the stored data)
- comparable_pool: peak_interactions
- status_note: We have only the single best observed post, so no mean exists. peak_post_engagement_rate is an UPPER BOUND, systematically higher than an average — never compare it against an average rate.
- unit_note: engagement_rate and peak_post_engagement_rate are ratios (0-1); avg_interactions_per_post and best_post_interactions are absolute counts. Read status before reading any number: a null rate has several different causes and status says which one applies here.

## Evidence
- [x_ai_dx_tsubota#1aa3d06d] 僕がClaude Codeの同時セッションを2〜3本に制限してる理由はこれ 工場がラインを止めて品質を守るように セッション数を絞って自分の判断力を守る 5本同時に動かして手戻りが出るより 3本で丁寧にやった方がトータルの生産量は上がる AIは速くなっても、使う人間の脳みそは変わらない (https://twitter.com/ai_dx_tsubota/status/2072999744528613591)
- [x_ai_dx_tsubota#e094f862] CLAUDE.mdは書き足すほど精度が落ちる Anthropicが7/24に発表した話なんだけど 自社のClaude Codeの指示書を80%以上削除しても 測定できるコーディング評価の劣化はゼロだった 指示が増えるほど「指示同士の衝突」が起きて Claudeの判断が重くなる とりあえずmd書き足すって発想は無駄を生む
- [x_ai_dx_tsubota#fc174b75] Claude Codeで制限にかかる一番の原因はだいたいこれ 全部の作業を同じモデル・同じ設定で動かしてること 軽い作業はSonnet 5のlow 重い戦略設計だけFable 5のhigh この使い分けだけでトークン消費が変わる
- [x_ai_dx_tsubota#7df28ca6] 業務の8割自動化できたのに、Chromeのログインだけ毎回手作業になってる これ、AIをガチで使ってる人ほど感じてる壁だと思う Claude in Chromeっていう拡張機能を入れると、ログイン済みのサイトをそのままClaudeに使わせられる ログインで詰まってた人は試してみる価値ある
- [x_ai_dx_tsubota#df0eba8e] AIで業務効率化するより先にやること 情報の公開範囲の確認 どんなに賢いツールも、使い方を間違えれば逆効果になる
- [x_ai_dx_tsubota#f7cde463] 思ってたのと逆だった effort上げるほど精度が上がると思ってたけど コーディングに限ってはある時点から逆に落ちる 頑張りすぎると空回りするのは人間と一緒だった
- [x_ai_dx_tsubota#3e6676f4] Opus 5を3日間触った正直な感想 ・4.8で多かった「指示無視」がほぼゼロになった ・長文タスクを渡してもブレない ・価格はFable 5の半額 Anthropicが「指示に一番素直なモデル」と言ってるの、体感で分かる 4.8に不満があった人は乗り換えていいと思う
- [x_ai_dx_tsubota#304e83aa] これ地味にでかい 非エンジニアがClaude Codeでツール作るとき、セキュリティってず

- commercial.audience_buyer_fit: source_type=ai_inferred, confidence=0.6, freshness_days=80, method=llm_scorer — Relative signal within Koinon indexing, not a market-wide score.

- quality.anomaly_flags: source_type=heuristic, confidence=0.5, freshness_days=111, method=profile_snapshot_and_engagement_ratio_heuristic — Means "worth a manual check", NOT confirmed fraud. Flags can be wrong and are not a verdict about the person.
- quality.authenticity_score: source_type=heuristic, confidence=0.5, freshness_days=80, method=Profile-shape heuristic from a single snapshot (follower count, following ratio, account age, posting volume, verification), reduced for engagement red flags where post engagement was collected. Where only a follower count is available the score saturates at 58. — The input set differs by platform; do not compare this score across platforms.
- quality.koinon_bd_grade: source_type=ai_inferred, confidence=0.5, freshness_days=111, method=llm_partner_fit_classifier + fit_score >= 0.6 AND authenticity >= 60 => A; fit_score >= 0.4 AND authenticity >= 45 => B; else C. authenticity < 30 or a promotional-pattern flag => quarantine. — Koinon partner-outreach fit, not creator quality.
