Handoffs

Purpose: Structured handoff templates for incoming sources (User / Tome / Saga / Harvest) and outgoing destinations (Growth / Prose / Stage / Canvas / Saga / Morph / Nexus). Read when: Receiving a handoff at FRAME, or preparing a deliverable handoff at PUBLISH.

Incoming Handoffs

From User → Zine

User inputs come in three shapes. Detect the shape at FRAME.

Shape 1: Concept-only

User gives a topic or thesis, no draft:

「Claude Skillsの連載、次は#09 Forgeを書きたい。Forgeはprototype担当のエージェント。」

Zine response at FRAME:

• Confirm platform (defaults to established series platform — here, note).
• Confirm this is #09 in the existing series.
• Re-read #00 Overview + #08 (previous episode) before drafting.
• Re-read series bible in .agents/PROJECT.md.
• Proceed to DRAFT. Generate full article from scratch.

Shape 2: Rough draft

User gives existing prose, wants restructuring / polish:

「こんな感じで書いたんだけど、もっと引きが強くできる？」[attached rough draft]

Zine response at FRAME:

• Read the full draft.
• Identify: what the draft is trying to say (thesis), what's working, what's throat-clearing, where the hook fails.
• Confirm with user: preserve voice vs full restructure?
• Proceed to STRUCTURE → POLISH (skip DRAFT, augment instead).

Shape 3: Source material → article

User gives raw material (git log, notes, PR descriptions, screenshots), wants Zine to author from scratch:

「このPR群から、月次の振り返り記事書いて」[attached PR list / git log]

Zine response at FRAME:

• Read all source material.
• Ask: platform, tone, retrospective vs announcement vs tutorial framing.
• Consider handoff-up to Tome if source is git-diffs (Tome specializes in git-to-learning-doc; Zine takes Tome's output and reshapes for public).
• Proceed to DRAFT.

From Tome → Zine

Tome generates learning documents from git diffs + decision history. Zine reshapes Tome's output for external audience.

Handoff format (Tome → Zine):

TOME_TO_ZINE_HANDOFF:
  source_commits: [commit hashes / range]
  learning_doc: [path to Tome's output]
  key_decisions:
    - decision: [what was decided]
      rationale: [why]
      impact: [what changed]
  technical_claims:
    - claim: [technical fact from diffs]
      grounding: [file/line reference]
  target_audience: [internal team | onboarding | external]
  suggested_platform: [if Tome has context, suggest]

Zine actions on receipt:

1. Read Tome's learning doc verbatim — preserve all technical claims as-is.
2. Identify 1-2 most interesting decisions as the article's thesis (Tome may list 10; a good article has 1-2 payloads, not 10).
3. Convert chronological / decision-order to reader-order (hook-first, not history-first).
4. Add hook, narrative framing, CTA.
5. Mask internal-only details (client names, unreleased features) before publish.

Preservation rule: Do not reword Tome's technical claims. If Tome says "changed from Redis pub/sub to NATS JetStream for at-least-once semantics", keep that phrasing; wrap narrative around it, don't rephrase.

From Saga → Zine

Saga writes product narratives (customer stories, scenario sagas). Sometimes those narratives want a technical blog variant.

Handoff format (Saga → Zine):

SAGA_TO_ZINE_HANDOFF:
  narrative: [path to Saga's customer-story output]
  protagonist: [customer / persona]
  conflict: [what problem they had]
  resolution: [how the product solved it]
  technical_backstory: [what engineering happened behind the scenes]
  external_tone_fit: [platform / audience Saga thinks this could land on]

Zine actions on receipt:

1. The customer story goes in the background, not foreground — external tech blog readers want the engineering perspective.
2. Reshape: Saga leads with customer; Zine leads with engineering challenge.
3. Credit the customer only if they've consented and Saga confirms.
4. Output: technical retrospective pattern (context → journey → lessons) with the customer story as the anchor moment.

From Harvest → Zine

Harvest collects GitHub PR data and generates work reports. PR-heavy periods seed release / retrospective posts.

Handoff format (Harvest → Zine):

HARVEST_TO_ZINE_HANDOFF:
  period: [YYYY-MM-DD to YYYY-MM-DD]
  prs: [list of PR titles, authors, labels, impact summaries]
  themes: [Harvest's auto-extracted themes — e.g., "performance", "a11y", "refactor"]
  notable_shipped_features: [list]
  notable_deprecated: [list]
  suggested_article_types:
    - "monthly release post"
    - "retrospective on X migration"

Zine actions on receipt:

1. Pick ONE theme to anchor the article. Harvest may suggest 3; a good article has 1 thesis.
2. Identify the PR that best embodies the theme (hero PR).
3. Zoom into the hero PR's story; the other PRs become supporting evidence.
4. Draft as: Retrospective pattern (if past-looking) or Announcement pattern (if forward-looking).

Outgoing Handoffs

Zine → Growth

Growth handles SEO / SMO / OGP / GEO (AI citation optimization). Zine delivers the canonical article + seed metadata; Growth adds keyword research, schema, social cards.

Handoff format (Zine → Growth):

ZINE_TO_GROWTH_HANDOFF:
  canonical_article:
    path: [Markdown file path]
    word_count: [count]
    platform: [note | Zenn | Qiita | dev.to | cross-post]
    target_reader: [persona description]
  title_candidates:
    - "[Candidate 1]"
    - "[Candidate 2]"
    - "[Candidate 3]"
  meta_description_draft: [~155 chars, ~120 chars for JP]
  h_tag_outline:
    - H1: "[Title]"
    - H2: "[Section 1]"
    - H2: "[Section 2]"
    ...
  og_text: [social card copy, ~100 chars]
  series_context: [if applicable — index URL, episode number]
  unlocked_claims: [verified technical claims that can be cited]
  growth_asks:
    - "Keyword research on [topic]"
    - "JSON-LD Article schema"
    - "Twitter/X card variant"
    - "OG image brief for Sketch handoff"

Scope boundary: Zine does not do keyword research, ranking strategy, AI-citation optimization (GEO), or JSON-LD schemas — all Growth territory.

Zine → Prose

Prose polishes microcopy / UX strings / CTAs. Zine hands off articles that contain embedded UI copy requiring consistent voice.

Handoff format (Zine → Prose):

ZINE_TO_PROSE_HANDOFF:
  article_path: [Markdown file path]
  microcopy_instances:
    - location: [line reference]
      text: "[current text]"
      context: [what this button/label/CTA is for]
  cta_block: [the article's closing CTA text]
  voice_guide: [link to series bible / voice doc]
  polish_scope: ["CTA only" | "all microcopy" | "voice tone consistency pass"]

Typical case: Article includes a screenshot with a "Subscribe" button; in-body sidebar with a signup CTA; closing CTA. Prose ensures these match product's in-app microcopy voice (not generic marketing voice).

Zine → Stage

Stage converts long-form to slide decks (Marp / reveal.js / Slidev) with WPM-calibrated pacing.

Handoff format (Zine → Stage):

ZINE_TO_STAGE_HANDOFF:
  article_path: [Markdown file path]
  article_word_count: [count]
  target_talk_length: [minutes — e.g., 20, 30, 45]
  key_beats:
    - beat: "[1-2 sentence summary]"
      suggested_slide_count: [1-3]
    - beat: "[1-2 sentence summary]"
      suggested_slide_count: [1-3]
  key_visuals_needed:
    - [diagram / chart / screenshot]
  audience: [conference type — e.g., JSConf JP, internal team, webinar]
  slide_framework_preference: [Marp | reveal.js | Slidev | no preference]

Scope boundary: Zine provides the narrative beats; Stage owns slide pacing (WPM calibration), visual design, transitions, and framework-specific output.

Zine → Canvas

Canvas generates Mermaid / ASCII / draw.io diagrams. Zine articles often need supporting figures (architecture diagrams, sequence flows, decision trees).

Handoff format (Zine → Canvas):

ZINE_TO_CANVAS_HANDOFF:
  article_path: [Markdown file path]
  figure_requests:
    - location: [H2 section where figure belongs]
      purpose: [what the figure illustrates]
      type: [flowchart | sequence | class | ER | state | C4 | journey]
      source_content: [prose or code the figure should visualize]
      output_format: [Mermaid | ASCII | draw.io]

Typical case: A deep-dive article about event-driven architecture needs a sequence diagram showing the happy path and a failure-mode diagram. Zine hands off the prose describing each; Canvas generates the Mermaid.

Zine → Saga

Sometimes a tech blog article has a strong customer-story angle that warrants reshaping for marketing. Zine hands off to Saga for customer-narrative reshape.

Handoff format (Zine → Saga):

ZINE_TO_SAGA_HANDOFF:
  article_path: [Markdown file path]
  technical_story: [1-3 sentences of the engineering angle]
  customer_angle: [1-3 sentences of the customer-value angle]
  persona_hint: [who the customer is, anonymized]
  consent_status: [customer-approved | anonymized | permission-pending]
  requested_output: [marketing site case study | customer testimonial page | pitch-deck slide]

Scope boundary: Zine writes for tech audience; Saga writes for buyer / customer audience. Same material, different framing, different outlet.

Zine → Morph

Morph converts formats (Markdown → PDF / Word / EPUB / HTML). When a series is mature enough to anthologize, Zine hands off to Morph.

Handoff format (Zine → Morph):

ZINE_TO_MORPH_HANDOFF:
  source_articles:
    - [article 1 path]
    - [article 2 path]
    - ...
  anthology_title: [title for PDF / book]
  target_format: [PDF | EPUB | Word | HTML standalone]
  cover_asset: [image path if available]
  toc_structure: [chapter ordering, not necessarily publish order]
  styling_preference: [preserve original | unified book styling | minimal]
  front_matter: [preface / acknowledgments / copyright / etc.]
  back_matter: [index / bibliography / about-the-author / etc.]

Typical case: Series reaches 15+ episodes; user wants PDF zine for download / paid sale. Zine confirms episode ordering, provides front/back matter text, hands off to Morph for PDF generation.

Nexus ↔ Zine Handoff

When Zine is invoked via Nexus (multi-agent chain), use the standard Nexus handoff format.

Nexus → Zine (AUTORUN input):

_AGENT_CONTEXT:
  Role: Zine
  Task: "Draft #09 Forge article for 図鑑 series"
  Mode: AUTORUN
  Chain: [User -> Nexus -> Tome -> Zine]
  Input:
    source: "Tome learning doc at docs/learning/forge-2026-04.md"
    series_context: ".agents/PROJECT.md has 図鑑 series bible"
  Constraints:
    - Platform: note
    - Series: 図鑑-#09
    - Tone: first-person teaching (matches #00-#08)
    - Length: 3500-5000字
    - Language: Japanese
  Expected_Output: "Full article + updated index + Growth handoff seed"

Zine → Nexus (AUTORUN output):

_STEP_COMPLETE:
  Agent: Zine
  Status: SUCCESS
  Output:
    deliverable: "articles/zukan/09-forge.md"
    artifact_type: "Article + Series Index Update"
    parameters:
      platform: note
      series_position: "図鑑-#09"
      hook_type: contradiction
      word_count: 4200
      tone: first-person teaching
      cta_type: next-episode
    files_changed:
      - path: articles/zukan/09-forge.md
        type: created
        changes: "Full #09 Forge article, 4200字"
      - path: articles/zukan/00-overview.md
        type: modified
        changes: "Added #09 to episode list; updated #10 as next planned"
  Handoff:
    Format: ZINE_TO_GROWTH_HANDOFF
    Content: "[Full handoff content — title candidates, meta desc, H-outline]"
  Artifacts:
    - articles/zukan/09-forge.md
    - articles/zukan/00-overview.md (diff)
    - metadata/note-tags-09-forge.yaml
  Risks:
    - "LOW CONFIDENCE: Forge's retry policy details — author should verify before publish"
  Next: Growth
  Reason: "SEO/OGP packaging for #09 before publish"

Handoff Decision Tree

Article deliverable ready
├── Needs SEO / OGP / social packaging?
│   └── → Growth
├── Needs microcopy / CTA voice polish?
│   └── → Prose
├── Will become a talk?
│   └── → Stage
├── Needs diagrams/figures?
│   └── → Canvas
├── Has customer-story angle for marketing?
│   └── → Saga
├── Series mature → anthology?
│   └── → Morph
└── None of the above → publish directly, notify user

Pick at most two downstream agents per article — fanning out to more agents dilutes coherence.
