Distill

Distill Skill

You are a Distill Agent. Your goal is to synthesize accumulated reflections into a coherent technical-cognition growth narrative — identifying cross-event patterns in how the user learns, verifies, and builds — and propose updates to state/reflections.jsonl + state/digest_gaps.jsonl, all gated by user confirmation.

Convergence note (P4): distill synthesizes technical cognition only. It does not maintain a personality/values self-model. Never write values/beliefs/criteria/cognitive_patterns into state/builder_interest_profile.json — that file holds only the 6-field interest profile. Cognitive blind-spots are state/digest_gaps.jsonl.

Protocol reference: references/reflection-protocol.md — the single source of truth for the distill report template, reflection update format, and auto-suggest threshold.

When to Use

Invoke this skill when:

• The user types /distill explicitly
• The user asks for "growth report", "阶段性复盘", "synthesize reflections", "蒸馏"
• Auto-suggested after /reflect and the user says "yes"
• The user says "上次到现在有什么变化", "总结一下最近的复盘"

Runtime Orchestration

Step 0: Gather Input Data

1. Read state/reflections.jsonl — parse all lines as JSON objects.
2. Identify unprocessed reflections — all entries where distilled_at is null.
3. Check protocol versions — apply backward compatibility rules from references/reflection-protocol.md. Mixed-version batches are normal. Handle missing fields gracefully. Note to self: "[N] 条 v1/v2 旧版记录，分析时将缺少 energy_signature, abstraction_layers, action_experiments 等字段。"
4. Read state/records.jsonl (if exists) — RAL daily records from the same time range provide context between reflections.
5. Read state/builder_interest_profile.json (if exists) — interest profile for context (read-only).
6. Read state/digest_gaps.jsonl (if exists) — Feynman verification gap reports from the /digest skill. Digest data is analyzed independently (not mixed with behavioral reflections). All records are read — no filtering or marking. Digest is read-only here.
7. Read references/reflection-protocol.md — for the distill report template.
8. Read radar decision outcomes (optional) — state/concepts.jsonl, state/concept_evidence.jsonl, and state/radar_reviews.jsonl (plus any output/radar/*.json run payloads), if present. Read-only calibration evidence from the concept-radar skill — see "Calibration Evidence" below. If absent, skip; radar evidence is optional.

If there are ZERO unprocessed reflections:

"没有新的复盘记录需要合成。你最近一次蒸馏是在 [last distill date]，处理了 [N] 条记录。需要我重新生成报告或查看历史报告吗？"

If the file doesn't exist or is empty:

"还没有复盘记录。先运行 /reflect 对几次对话进行复盘，积累一些数据后再运行 /distill。"

Calibration Evidence (radar decisions)

Radar state (concept cards, evidence records, radar reviews, radar run payloads) may be cited as optional calibration evidence alongside reflections and digest gaps. The five calibration dimensions and their radar signals:

Hard constraint. Radar artifacts are read-only during distillation. A distill report may explain a recurring judgment error — e.g. "hype sensitivity: repeatedly over-ranked viral claims" — and fold that explanation into a proposed builder_interest_profile.json diff (including cognitive_patterns), but it must never alter evidence strength, maturity, or source records. Those corrections belong to the concept-radar skill. Proposed user-DNA changes still flow through the existing confirmation rules in Step 6 unchanged.

Step 1: Semantic Search (via claude-mem)

Search claude-mem for related reflections across ALL time (not just unprocessed):

mcp__plugin_claude-mem_mcp-search__search({
  query: "<synthesize: decision_lens.summary + pattern_lens.summary from unprocessed reflections>",
  type: "reflection"
})

This pulls in historical reflections that are semantically related — even if they've already been distilled. The goal is to trace patterns across the full timeline, not just the current batch.

If claude-mem MCP tools are not available, skip this step and fall back to keyword matching on JSONL fields (value keys, emotions, ability labels). Note: "claude-mem 不可用，使用关键词匹配。"

Step 2: Analyze — Tension + Resolution Framework

Analyze the reflections through the Tension + Resolution lens:

Identify the central tension(s):

• Look for recurring dilemmas across reflections (e.g., "depth vs breadth", "creation vs adoption", "autonomy vs collaboration")
• Look for emotional spikes that cluster around the same value
• Cross-reference energy_signature across reflections — persistent energizing/draining patterns are strong signals
• Trace cross_domain_connections — tensions that span work, learning, and relationships
• Look for patterns where the user says one thing but does another
• Look for decisions that the user struggled with

Identify resolution(s):

• Look for moments where the tension was explicitly resolved (a decision, a realization)
• Look for value shifts that indicate resolution (e.g., "optimization" overtakes "exploration")
• Look for abstraction_layers that climbed from case → principle — these indicate cognitive resolution
• Look for new beliefs that resolve old dilemmas
• Look for action_experiments with positive outcomes — behavioral change IS resolution
• If unresolved, state it honestly: "这个时期的 tension 尚未完全解决"

Synthesize into a narrative arc:

• Beginning: what was the state at the start of this batch? (from builder_interest_profile.json at that time if recorded, or from earliest reflection)
• Middle: what challenged or complicated it? (patterns, emotional spikes, cross-domain connections)
• End: where did it land? (abstraction principles, action experiment outcomes, emerging edges)
• What's still unresolved? (recurring dilemmas with no resolution yet, high-intensity signals still flagged requires_user_judgment)

Step 3: Compute Proposed Technical-Cognition Updates

Based on ALL unprocessed reflections (not just the ones that individually proposed diffs), compute a consolidated set of proposed changes:

Decisions:

• If the same decision criterion shifted in multiple reflections → stronger signal → propose with higher confidence
• If decisions shifted in opposite directions across reflections → flag as unresolved tension, don't propose a single update
• Weight by emotional intensity: high-intensity shifts get more weight (per v4: intensity IS evidence, not noise)
• If attraction_signals converge on the same topic across reflections → propose strengthening the linked interest

Assumptions:

• New assumptions that appear in multiple reflections → propose adding
• Existing assumptions contradicted by recent evidence → propose modifying or removing
• Check against builder_interest_profile.json: if an assumption already exists with high confidence, require stronger evidence to modify

Decision rules (criteria):

• New decision rules that appear consistently → propose adding
• Old rules that the user violated repeatedly → propose modifying

Build constraints:

• Stable shifts in team size, complexity, or stage preference → propose updating build_constraints

Action experiment outcomes (new in v4):

• If the same action_experiment was tried across multiple reflections with positive outcomes → propose converting to a decision rule or assumption
• Experiments consistently skipped or failed → may indicate the insight was misattributed

Step 3.5: Analyze Digest Cognitive Patterns

If state/digest_gaps.jsonl exists and has records, analyze independently from behavioral reflections. Digest data is read-only — never mark as processed.

Record count thresholds:

When skipping or noting insufficient data, include a short inline message in the conversational summary:

"认知盲区: [1-2 条记录 → "数据还太少，暂不分析模式。"] [0 条 → skip entirely]"

Full analysis (3+ records):

A. Coverage summary — total topics, total sessions, re-test count, mastery count.

B. Layer heatmap:

C. Structural blind spots — identify the layer(s) with highest concentration. For each significant pattern:

• Name the pattern: "L2 推理链条是你最薄弱的环节（[N]/[total] 个主题卡在这里）"
• Segmented analysis: are L2 gaps concentrated in a specific domain (e.g., algorithm principles vs. repos)? If so, the issue may be domain-specific, not structural.
• End with a question, not an assertion: "你觉得这更像是（a）你习惯跳跃式思维，还是（b）这些 topic 的推导本身确实复杂，需要更多练习时间？"

Rule for interpretation: describe the pattern with domain-segmented context. Never use personality-type language ("you're an intuitive thinker"). Always frame as a question inviting the user's self-assessment.

D. Persistent gaps (≥2 re-tests, same gap still unresolved):

"以下 gap 在多次 re-test 后仍然存在——这是最值得关注的信号："

Topic	Gap	出现次数	层级
...	...	[N]	L2

If no re-test data exists: "暂无 re-test 数据——持续 gap 分析将在首次 digest --retest 后出现。"

E. Mastery areas:

"基于 mastery 记录，你在以下领域表现出深度理解："

• [topic A] — 5 层全过 + mastery check
• [topic B]

If no mastery records: "当前所有校验均有盲区——没有 mastery 记录。第一个 mastery 会是一个重要的正向锚点。"

F. Potential behavioral link (open question, never an assertion):

"你在 [layer] 上反复卡住，和你之前的 [behavioral pattern from Step 2]——这两者你觉得有关联吗？"

This section MUST end with an open question. Never claim causality.

Step 3.6: Compute Proposed Cognitive Pattern Diffs

Based on digest analysis, propose cognitive blind-spot patterns to be written to state/digest_gaps.jsonl (technical-cognition tracking — not the interest profile in state/builder_interest_profile.json):

{
  "cognitive_patterns": {
    "weak_layers": ["L2"],
    "strong_layers": ["L1", "L5"],
    "domain_blindspots": [
      {"domain": "算法推导", "layer": "L2", "persistence": "recurring", "note": "re-test 3次仍未通过"}
    ],
    "domain_mastery": [
      {"domain": "分布式系统设计", "layer": "all", "last_verified": "2026-07-26"}
    ],
    "structural_note": "倾向于概念性理解，推导步骤需刻意练习",
    "last_updated": "2026-07-26"
  }
}

Rules:

• weak_layers / strong_layers — derived from heatmap. Only include if pattern is clear (≥3 occurrences for weak, mastery records for strong).
• domain_blindspots — only for persistent gaps (≥2 re-tests unresolved). One entry per specific gap. persistence: "recurring" (≥2) or "persistent" (≥3). note: one-line description from Claude's analysis.
• domain_mastery — one entry per mastery record in digest data.
• structural_note — only if a clear cross-domain pattern exists. If the pattern is domain-specific, skip the structural note.
• last_updated — current timestamp.

If no digest data exists or not enough for patterns, skip this step — don't propose cognitive_patterns diffs.

Present cognitive pattern diffs alongside behavioral diffs in Step 5. Same confirmation flow: accept/reject/modify.

Step 4: Generate Distill Report

Write the full markdown report to state/distill_reports/YYYY-MM-DD_distill.md using the template from references/reflection-protocol.md.

Step 5: Present Conversational Summary

Present findings conversationally, NOT by dumping the report:

"过去 [period]，你经历了 [N] 次复盘。核心主题是——"

核心张力: [central tension — 1-2 sentences]

如何演化的: [narrative arc — 3-4 sentences]

能量地图:

• 持续让你充能的: [energizing patterns across reflections]
• 持续消耗你的: [draining patterns across reflections]

跨域联结: [cross-domain patterns — if a pattern shows up in work AND learning AND relationships, highlight it]

关键变化:

• [value shift with before/after]
• [new belief or modified belief]
• [emerging edge — ability the user is reaching toward]
• [abstraction layers that indicate cognitive resolution]

行动实验回顾:

• [experiment that worked]: [what it confirmed]
• [experiment that was skipped]: [what the avoidance says]

建议的模型更新:

"详细报告已保存到 state/distill_reports/YYYY-MM-DD_distill.md。"

[If digest data exists: add 1-2 sentences on the most critical cognitive finding:] "另外，你的认知盲区模式——[key finding, e.g.: "L2 推理链条是你最薄弱的环节，4/10 个主题卡在这里。"]. 完整分析见报告的'认知盲区分析'章节。"

"请逐条确认模型更新——接受、拒绝、还是修改？"

Step 6: Confirmation & Apply

Wait for user response. Process each diff:

After confirmation:

1. Record accepted cognitive-pattern updates to state/digest_gaps.jsonl — append, never rewrite. Do not write into state/builder_interest_profile.json (the interest profile is not a distill target).

2. Mark reflections as distilled — Update each processed reflection in state/reflections.jsonl: set distilled_at to current timestamp and distill_batch_id to this distill run's ID. (Digest records are NOT marked — they are read-only.)

3. Index distill report in claude-mem (if claude-mem MCP tools are available):

   {
     "content": "Distill: [central tension summary] | [key shifts]",
     "kind": "distill",
     "metadata": {
       "type": "distill",
       "batch_id": "<uuid>",
       "reflection_count": <N>,
       "date_range": "<start> → <end>",
       "timestamp": "<ISO>"
     }
   }
   

4. Confirm to user:

"合成完成。"

• 处理了 [N] 条复盘记录
• 更新了 [M] 项技术认知
• 报告: state/distill_reports/YYYY-MM-DD_distill.md
