package

Packager

Stage a product for distribution with triple manifests (MyClaude + Anthropic Plugin + Agent Skills universal).

When to use: After /validate passes. Before /publish.

When NOT to use: If the product hasn't been validated yet (run /validate first).

---

Activation Protocol

1. Shared preamble: Load references/quality/activation-preamble.md — context assembly, persona adaptation, deterministic routing rules.
2. Identify product: $ARGUMENTS as slug → workspace/{slug}/

1b. Mode selection (Express vs Guided). Read creator.yaml → preferences.workflow_style. Resolve the flow mode:

• --express flag OR workflow_style == "autonomous" → Express mode. Skip the "confirm before stage" prompt, skip the manifest preview step, and produce a single post-stage summary. The safety invariants below still hold — only the conversational confirmations are trimmed.
• workflow_style == "guided" or missing → Guided mode (default). Confirm before staging, show manifest preview, and walk the creator through the pipeline with full voice.
• Read .meta.yaml → verify state is "validated" and MCS score >= 75%
• Read creator.yaml → load author metadata for manifests. If missing → "Creator profile not found. Run /onboard first." and stop.
• Maintain creator persona: Adapt language, depth, and examples to profile.type and technical_level throughout this skill's execution. A developer gets code examples; a domain expert gets plain language.
• Load product-dna/{type}.yaml → get install_target
• Load config.yaml → vault_defaults for missing fields

6b. Load proactives: Load references/engine-proactive.md — wire #1 (pipeline guidance: after package, guide to /publish), #20 (test mandate: if MCS-2+ and .meta.yaml.test_result != "pass", block packaging with message "Run /test first").

1. Load voice identity: Load references/quality/engine-voice-core.md. Every user-facing line in this skill honors the ✦ signature, three tones, and six anti-patterns.
2. CLI contract: Load references/cli-contract.md for unified error handling. This skill has conditional severity based on pricing model. Severity map:
3. Blocking (paid products only): stripe status — if product price > 0 and Stripe not connected, halt packaging
4. Silent-skip (free products): stripe status — irrelevant for free products, skip without warning
5. Silent-skip: search --category {type} --sort price-desc — competitive pricing scan, skip without warning on failure
6. All queries: append 2>/dev/null, 15s timeout, treat invalid JSON as CLI absent

Core Instructions

PACKAGING PIPELINE

SAFETY INVARIANTS — see end of file (positioned per D19 attention-aware authoring for maximum model compliance).

Step 1 — Verify Validation

Read .meta.yaml for validation state:

• If state != "validated" AND state != "packaged": "Product not validated. Run /validate first."
• If MCS score < 75%: "Product below MCS-1 threshold. Run /validate --fix."
• If mcs_target is "MCS-2" or "MCS-3" AND (test_result is null OR test_result != "pass"): "MCS-2+ products require behavioral testing before packaging. Run /test first." — BLOCKING. This gate ensures structural validation (/validate) AND behavioral validation (/test) both pass before distribution.

Step 1.5 — Package Rename (if applicable)

Check product-dna/{type}.yaml for package_rename field. If present, rename the primary file to the specified pattern during copy to .publish/.

Currently applies to:

• minds: AGENT.md → {slug}.md (flat file convention for .claude/agents/)

This rename ensures the installed filename matches Claude Code's native discovery pattern.

Step 2 — Strip WHY Comments + Inject Attribution (SE-D17)

Create a clean copy of all product files.

REMOVE:

• <!-- WHY: ... --> (HTML comment blocks — may span multiple lines)
• Lines matching # WHY: pattern (markdown comment format)
• # WHY: pattern in shell scripts (.sh files)
• JSON keys prefixed with _ (e.g., _comment, _why, _events_reference) from .json files. These are documentation keys used in workspace but must not pollute the user's settings.json when hooks are installed. Strip by parsing JSON, removing _-prefixed top-level keys, and re-serializing.

INJECT TWO THINGS into the .publish/ copy of the primary file (SKILL.md, AGENT.md, etc.):

1. Marketplace URL in frontmatter (PRD D3 — viral vector #1): Add a marketplace_url field to the YAML frontmatter of the primary file. This field is read by Claude Code in EVERY session where the product is installed — making every buyer a passive distribution carrier.

---
name: {slug}
description: >
  {original description — DO NOT MODIFY}
marketplace_url: "https://myclaude.sh/p/{slug}"
---

Rules:

• Add marketplace_url as a NEW field — never modify the existing description
• Only add to the .publish/ copy — never touch the original in workspace/
• Use the slug from vault.yaml

2. Attribution comment at end of file:

<!-- Published on MyClaude (myclaude.sh) | Quality: MCS-{level} ({score}%) | Engine: Studio v3 -->

This attribution comment is:

• Invisible to Claude (HTML comment, does not affect behavior)
• Visible in source code (GitHub renders it in raw view)
• Indexable by search engines (creates discoverable MyClaude references)
• A quality signal (MCS score travels with the product)

Never modify originals — work on the copy in .publish/.

Step 2c — Inject README Badges (PRD B2 — viral vectors #2)

Append MCS and Available badges to the end of .publish/README.md:

---

[![MCS-{level}](https://myclaude.sh/badge/mcs/{level}.svg)](https://myclaude.sh/quality)
[![Available on MyClaude](https://myclaude.sh/badge/available.svg)](https://myclaude.sh/p/{slug})

<sub>Built with MyClaude Studio Engine</sub>

Precondition: Verify .publish/README.md exists before injection. If missing (bundle type has no README requirement), skip badge injection silently — do not create a README just for badges.

README quality gate: Before badge injection, verify README follows templates/readme/README.md.template structure — at minimum: Hero, Install (with myclaude install {slug}), Quick Start, Features (3+), Requirements. If missing critical sections, WARN: "README is missing sections that help users decide to install. Consider running /fill to complete it." Continue packaging — this is advisory, not blocking.

Rules:

• Inject ONLY in .publish/README.md — never modify the original
• MCS level from .meta.yaml state.dna_compliance or overall_score. Default to 1 if not validated
• Slug from vault.yaml name field
• Add a blank line before the --- separator to avoid markdown parsing issues

Step 2b — Verify WHY Removal

Grep all files in .publish/ for the pattern WHY:. If match count > 0, re-run stripping on the matched files. If still > 0 after second pass, report error with file paths and line numbers — do not proceed to manifest generation with unstripped WHY comments.

Step 2d — Post-Strip Integrity Check

After WHY removal, verify the stripped files are still structurally valid:

• For .md files: verify YAML frontmatter still parses (regex for ^---\n ... \n---\n)
• For .json files (hooks.json, settings-fragment.json): parse with JSON validator after _-prefixed key removal. If parse fails → abort with file path and error. Never ship invalid JSON.
• For .sh files: verify shebang line survived stripping (first line must start with #!)
• If any check fails: report the specific file + line + issue. Do NOT proceed to manifest generation.

Step 3 — Generate vault.yaml

Read .meta.yaml → intent_declaration.language (written by /create Step 11). This is the canonical source of truth for the product's source language — it captures what language the product was forged in, not what language the creator is currently using. If the field is missing (pre-Wave-3 legacy product), fall back to creator.yaml → creator.language, then to "en" as the final default.

# REQUIRED (from .meta.yaml + creator.yaml)
name: "{slug}"
version: "{from .meta.yaml or config default}"
type: "{product type}"
description: "{from README.md first paragraph or .meta.yaml}"
entry: "{primary file from product-dna/{type}.yaml}"
license: "{from creator.yaml or config default}"
price: {from .meta.yaml or 0}
tags: ["{from .meta.yaml}"]

# LOCALE CONTRACT — see references/locale-adaptive-clause.md §8 for the full wiring map.
# source_language travels with the product to the marketplace so the UI can
# render the "Source: {language} · Adapts to your language at runtime" badge.
# These four fields are REQUIRED for any product that was forged with the
# locale-adaptive clause (all 6 certified types). Omit the block only for
# types that do not carry the clause (bundle, claude-md, application, hooks,
# statusline, design-system, workflow — per locale-adaptive-clause.md §4).
source_language: "{from .meta.yaml intent_declaration.language, fallback to creator.yaml language, fallback to 'en'}"
locale_adaptive: true
locale_adaptive_source: "references/locale-adaptive-clause.md"
locale_adaptive_version: "1.0"

Step 3b — Pricing Intelligence (Intelligence Layer integration)

Read .meta.yaml → intelligence fields. If value_score is populated (set by /validate Stage 8), display value-informed pricing context:

Value Intelligence:
  Value score: {value_score}/12 ({pricing_strategy})
  Suggested range: ${suggested_price_range[0]}-${suggested_price_range[1]}
  Current price: ${price from .meta.yaml or vault_defaults}
  {If price == 0 AND value_score >= 5: "Your product scores {value_score}/12 — consider pricing at ${suggested_price_range[0]}+ based on depth and uniqueness."}
  {If price > 0 AND price > suggested_price_range[1]: "Current price exceeds value signal range. Ensure README clearly communicates the premium."}
  {If price > 0 AND price < suggested_price_range[0]: "Priced below value signal. You're leaving value on the table — or strategically building audience."}
  {If value_score not set: "Run /validate --level=2 to compute value intelligence."}

If the product has a non-zero price:

1. Stripe check: Run myclaude stripe status 2>/dev/null
2. If not connected: BLOCKING — "Paid products require Stripe. Run myclaude stripe connect first."
3. If connected: proceed

1. Competitive pricing scan: Run myclaude search --category {type} --sort price-desc --limit 5 --json 2>/dev/null If results found, display: ``` Pricing context for {type} products: Highest: ${max_price} ({name}) Average: ${avg_price} Your price: ${price} {If price > avg: "Premium positioning" | If price < avg: "Value positioning" | If price == 0 and others charge: "Consider charging — similar products average ${avg}"} ```

1. MCS-price alignment: If price > $5 AND mcs_level < 2, warn: "Price is ${price} but MCS is level {level}. Users expect MCS-2+ for paid products. Consider running /validate --level=2 to increase quality."

Epistemic caveat (always shown when value intelligence is displayed):

"Value signal is estimated from structural quality + market position. Real value is confirmed by daily use."

Continue to enrichment:

# ENRICHMENT (from .meta.yaml + creator.yaml + computed)
displayName: "{humanized from name}"
mcsLevel: {from last validation score}
language: "{from creator.yaml}"
longDescription: "{from README.md}"
readme: "README.md"
installTarget: "{from product-dna/{type}.yaml}"
language: "{from creator.yaml or 'en'}"
compatibility:
  claude_code: ">=1.0.0"

# DISTRIBUTION DNA (viral growth layer — links back to MyClaude ecosystem)
engine: "myclaude-studio-engine"
marketplace: "https://myclaude.sh/p/{slug}"
badges:
  mcs: "https://myclaude.sh/badge/mcs/{mcs_level_number}.svg"
  available: "https://myclaude.sh/badge/available.svg"

Step 4 — Generate plugin.json (Anthropic Plugin Marketplace)

Settings priority: Plugin settings are LOWEST priority in CC's 6-level hierarchy (Plugin < User < Project < Local < Flag < Policy). This means user/project settings always override plugin defaults. Hooks from plugins ACCUMULATE (never replace existing hooks). MCP servers from plugins REPLACE entirely.

Schema constraints (enforce strictly — wrong structure causes silent install failures):

• author MUST be an object { "name": "...", "url": "..." } — never a plain string
• skills field uses a directory path (e.g., ".claude/skills/slug/") — CC loads all .md files in it
• agents field uses an explicit file path array (e.g., [".claude/skills/slug/AGENT.md"]) — NOT a directory
• commands field uses a directory path (e.g., ".claude/commands/")
• hooks key does NOT belong in plugin.json — hooks are declared in a separate hooks.json file
• Only agent key is valid inside settings.json plugin settings (not skill, workflow, etc.)

Emit only the fields relevant to the product type:

{
  "name": "{slug}",
  "description": "{description}",
  "version": "{version}",
  "author": { "name": "{from creator.yaml display_name}", "url": "https://myclaude.sh/u/{from creator.yaml username}" },
  "license": "{license}",
  "homepage": "https://myclaude.sh/p/{slug}",

  // --- Include ONE of the following blocks based on product type ---

  // type=skill or type=workflow or type=squad or type=claude-md:
  "skills": ".claude/skills/{slug}/",

  // type=agent:
  "agents": [".claude/skills/{slug}/AGENT.md"],

  // type=minds:
  "agents": [".claude/agents/{slug}.md"],

  // type=system (if it exposes commands):
  "commands": ".claude/commands/"

  // NOTE: hooks type — no content field in plugin.json. hooks.json is the artifact.
  // NOTE: statusline type — no content field in plugin.json. statusline.sh is the artifact.
  // NOTE: design-system, application, bundle — no content field; vault.yaml handles install.
}

Step 4b — Generate agentskills.yaml (Agent Skills Universal — 33+ platforms)

The Agent Skills format (YAML frontmatter + markdown instructions) is the structured skill definition format used natively by Claude Code and recognized by other AI coding tools. Generate this manifest for cross-platform compatibility.

# Agent Skills Universal Manifest
name: "{slug}"
version: "{version}"
description: "{description}"
type: "{product type}"
author: "{from creator.yaml}"
license: "{license}"
entry: "{primary file}"
platforms:
  - claude-code
  - cursor
  - codex
  - gemini-cli
  - copilot
  - "*"  # Compatible with any Agent Skills-compliant platform
install:
  target: "{from product-dna install_target}"
  files:
    - "{list all files in .publish/ relative paths}"
metadata:
  mcs_level: "{from validation}"
  mcs_score: "{from validation}"
  marketplace: "https://myclaude.sh/p/{slug}"

Only generate for types that map to Agent Skills format (skill, agent, prompt, workflow). For types that don't map cleanly (design-system, application), generate only vault.yaml + plugin.json.

Step 5 — Calculate Checksum

SHA-256 of the entire .publish/ directory contents.

Step 6 — Stage .publish/

Create workspace/{slug}/.publish/ with:

• Cleaned product files (WHY comments stripped)
• vault.yaml (MyClaude marketplace)
• plugin.json (Anthropic plugin marketplace)
• agentskills.yaml (Agent Skills universal — if applicable type)
• CHANGELOG.md (generate if missing)
• LICENSE.md file (generate from license field — use .md extension, CLI rejects extensionless files)

EXCLUDE from .publish/ (internal Engine files — never distribute):

• .meta.yaml (Engine product state tracking)
• domain-map.md (creator's working notes)
• Any file starting with . (hidden files, including .env)
• Files matching secret patterns: *.pem, *.key, *.p12, credentials*.json, *.env
• If any excluded-for-secrets file is found, WARN: "Sensitive file {file} excluded from package. If this is intentional, rename it."

Step 6c — Double-Source Secrets Scan

Run the same secrets scan patterns (from config.yaml → secret_content_patterns) against BOTH .publish/ AND workspace/{slug}/ originals. Compare results. If .publish/ has MORE matches than originals (stripping logic injected content), this is a CRITICAL error — abort packaging immediately and report the discrepancy.

Step 6b — Verify Type-Specific Install Artifacts

The CLI install command has type-specific handlers. The tarball MUST contain the artifacts each handler expects, or install will silently skip critical operations.

| Type | Required in .publish/ | CLI Install Behavior | |------|----------------------|---------------------| | hooks | hooks.json + scripts/ (with .sh files) | Merges hooks.json into settings.local.json + copies scripts/ | | statusline | statusline.sh + settings-fragment.json | Copies script + merges statusLine config into settings.local.json | | minds | {slug}.md (renamed from AGENT.md in Step 1.5) | Copies flat file to .claude/agents/{slug}.md |

Verification (MUST pass or abort):

For hooks:

• hooks.json exists in .publish/ → FAIL if missing
• hooks.json is valid JSON with top-level "hooks" key → FAIL if malformed
• scripts/ directory exists with at least one .sh file → FAIL if missing
• JSON _-prefixed keys were stripped in Step 2 (e.g., _comment, _events_reference)

For statusline:

• statusline.sh exists in .publish/ → FAIL if missing
• statusline.sh has shebang #!/usr/bin/env bash → WARN if missing
• settings-fragment.json exists with "statusLine" key → FAIL if missing

For minds:

• {slug}.md exists in .publish/ (Step 1.5 should have renamed it) → FAIL if missing
• File has YAML frontmatter with denied-tools → WARN if missing (advisory-only guarantee)

For all other types: no additional verification (default install path handles them).

If any FAIL: abort with message listing missing artifacts and expected structure.

Step 7 — Re-validate

Run Stage 1 (structural) + Stage 6 (CLI preflight) on .publish/ contents. If any check fails, report and abort — don't leave broken package.

Step 8 — Update State

# .meta.yaml updates
state:
  phase: "packaged"
  packaged_at: "{ISO timestamp}"

Output Format

UX Stack (load before rendering output):

1. references/ux-experience-system.md §1 Context Assembly + §2.2 Archetype-Aware Insights (pricing emphasis per creator goals)
2. references/ux-vocabulary.md — translate all terms
3. references/quality/engine-voice.md — Brand DNA

Cognitive rendering: /package is a transition moment — the product is ready to meet the world. Adapt output: creators with revenue goals get pricing intelligence front-and-center. Community-focused creators get distribution channel emphasis. Expert creators get compact technical summary. Beginners get reassurance: "Your product passed quality checks. One step to publish." Always include the install command preview as identity reinforcement — seeing myclaude install @{username}/{slug} makes it real.

CRITICAL: Load references/ux-vocabulary.md for UX tier names and type names.

┌─────────────────────────────────────────────┐

│  Quality: {ux_tier} {stars}                 │

SAFETY INVARIANTS (D19 — critical constraints in high-attention zone)

[SOURCE: CC commit handling — never --amend, --no-verify, force push]

These are ABSOLUTE rules that cannot be overridden:

1. Never overwrite .publish/ without confirmation — if .publish/ already exists, ask before replacing
2. Never include secrets — re-run secrets scan from /validate Stage 2 on .publish/ contents AFTER stripping
3. Never strip creator content — only strip WHY comments, _prefixed JSON keys, and .meta.yaml. All content the creator wrote must survive packaging intact
4. Never modify workspace originals — all transformations happen on the .publish/ copy
5. Verify frontmatter completeness — check product-dna/{type}.yaml → frontmatter.required[]. Missing required fields in .publish/ → block with: "Required frontmatter field '{field}' missing. Add it to your product file, then re-run /package." [SOURCE: cc-platform-contract.md §2.1]
6. Compact Instructions preservation — if the workspace file has ## Compact Instructions, it MUST survive into .publish/. This section is NOT a WHY comment — it's functional product content read by Claude Code's compact system [SOURCE: compact/prompt.ts:133-143]

---

Anti-Patterns

1. Packaging unvalidated product — Always check .meta.yaml state first.
2. Modifying originals — Work on copies in .publish/. Never touch workspace/{slug}/ source files.
3. Missing manifests — vault.yaml + plugin.json required. agentskills.yaml for compatible types. Triple distribution.
4. Stale checksum — Recalculate if any file changes after initial staging.
5. Silent failures — If WHY stripping breaks markdown structure, detect and report.
6. Missing install artifacts — hooks without scripts/, statusline without settings-fragment.json. Step 6b catches these. If /validate passed but /package fails here, the DNA spec is missing a required file check.
7. Shipping _comment keys in hooks.json — Step 2 strips _-prefixed JSON keys. Verify after strip: no _comment, _why, _events_reference in .publish/ JSON files.

---

Compact Instructions

When context is compressed, preserve:

• Product slug, type, and packaging state
• Whether WHY stripping completed successfully
• Manifest generation status (vault.yaml, plugin.json, agentskills.yaml)
• Pricing intelligence results if computed
• Any blocking issues (secrets detected, frontmatter missing, JSON invalid)
• .publish/ directory path and file count
