Initialize the 3-layer memory structure for cross-session AI continuity.

Overview

Creates memory/ (permanent, agent-focused) and wiki/ (long-term, human+AI) directories with template files, then injects the Session Memory Protocol into the project's agent configuration file.

The result is a structured memory system that:

• Costs ≤ 3000 tokens at session startup
• Is human-readable in Obsidian (valid markdown with wikilinks)
• Self-compacts via size caps and rotation rules
• Integrates with the Corgi lifecycle (apply closeout, archive extraction)

When to Use

• After corgispec-install completes (called automatically unless --no-memory)
• Manually via /corgi-memory-init to add memory to an existing Corgi project
• When a project needs cross-session continuity but doesn't have memory/ or wiki/ yet

Do not use this skill to modify memory contents, run lint checks, or extract knowledge from changes.

Preconditions

• Target project has openspec/config.yaml
• Target project root is known (current working directory or specified path)

Steps

1. Detect project identity and extract knowledge

Read the target project's root for context:

1. If README.md exists → extract project name and purpose (first heading + first paragraph)
2. If CLAUDE.md exists → extract:
   • Tech stack (languages, frameworks, databases, infrastructure)
   • Hard constraints (lines with "must", "never", "always", "required", "forbidden")
   • Preferences (style, naming conventions, patterns to follow)
   • Architecture notes (component descriptions, service boundaries)
3. If AGENTS.md exists → extract same categories as CLAUDE.md (merge, deduplicate)
4. If GEMINI.md exists → extract same categories (merge, deduplicate)
5. If package.json exists → extract project name from name field, framework info from dependencies
6. If docs/ exists → scan top-level .md filenames for architecture clues (don't deep-read, just note presence)

Store extracted values for template population:

• PROJECT_NAME: from README heading or package.json name
• PROJECT_PURPOSE: from README first paragraph
• TECH_STACK: from agent configs + package.json deps
• HARD_CONSTRAINTS: bullet list from agent configs (max 15)
• PREFERENCES: bullet list from agent configs (max 10)
• STABLE_COMPONENTS: well-established tech from stack info
• EVOLVING_COMPONENTS: anything described as new/experimental, or "TBD"
• LEGACY_COMPONENTS: anything described as deprecated/debt, or "None identified"

If a file doesn't exist or a value can't be extracted, use placeholder text.

Note: This is a lightweight extraction for initial setup. For deep knowledge migration from existing projects, run /corgi-migrate after init completes.

2. Create memory/ directory structure

Create the following files. Skip any file that already exists — never overwrite.

memory/
├── MEMORY.md
├── session-bridge.md
└── pitfalls.md

memory/MEMORY.md

---
type: memory
created: <today's date YYYY-MM-DD>

## Done (last session completed)
- (initial setup — memory structure created)

## Waiting (next steps / blockers)
- First change not yet created — run `/corgi-propose`

## New Pitfalls

## Active

(No pitfalls yet — these accumulate during corgi apply sessions)

3. Create wiki/ directory structure

# Wiki Schema — Page Types, Frontmatter & Update Contract

## A. Page Types & Frontmatter

| type | 必需欄位 | 可選欄位 |
|------|---------|----------|
| pattern | `type: wiki`, `created`, `source_change` | `tags` |
| decision | `type: wiki`, `updated`, `status` (proposed/accepted/superseded) | `source`, `tags` |
| session | `type: wiki`, `created`, `source_change`, `status` | `tags` |
| research | `type: wiki`, `updated`, `source` | `tags` |
| meta | `type: wiki`, `generated` | `tags` |

> `wiki/architecture/` is planned but not yet active — no `_index.md` needed until content exists.

## B. Update Contract

| 觸發操作 | 必須同步的動作 |
|----------|---------------|
| 在 wiki 子目錄下新增或刪除任一 .md | 更新對應的 `_index.md` |
| 完成 `corgispec-archive` | 追加 `wiki/log.md` 一條記錄 |
| 完成 `corgispec-archive` | 檢查是否有可抽取的 decision → 若有則創建 decision page |
| 完成 `corgispec-memory-extract` | 更新對應 `_index.md` |
| 完成一次 session | 同時更新 `memory/session-bridge.md` 和 `wiki/hot.md` |
| 跑 `/corgi-lint` | 檢查 orphan page、frontmatter 合規、_index 同步、log 覆蓋率 |

## C. Exemptions

- **Root-level files** (`hot.md`, `index.md`, `schema.md`, `log.md`) 不受 `_index.md` 覆蓋要求約束
- 頁面可透過 `unlisted: true` frontmatter 欄位從 `_index.md` 中排除

## D. Log Format

`wiki/log.md` 採 append-only，每行一事件：

\`\`\`
YYYY-MM-DD | action change-name | +added-file -removed-file

4. Inject Session Memory Protocol

Check the agent configuration file for an existing ## Session Memory Protocol section:

1. If CLAUDE.md exists → check for ## Session Memory Protocol
2. If AGENTS.md exists → check for ## Session Memory Protocol

If the section already exists → skip injection, report "Session Memory Protocol already present."

If the section does NOT exist → append the following block to the end of the primary config file (CLAUDE.md if it exists, otherwise AGENTS.md):

## Session Memory Protocol

### Startup (every session)
Read in order, max 3 files:
1. `memory/session-bridge.md` — last session's state
2. `wiki/hot.md` — current project context (~500 words, hard cap 600)
3. `wiki/index.md` — jump to relevant domain page
Then read `docs/` or code as needed.

### Retrieval Budget
- Startup: max 3 files (session-bridge + hot + index), then on-demand
- Per-question: max 2 wiki pages before answering
- If >5 pages needed: say "this needs a deep session"

### File Size Limits (hard caps)
| File | Target | Hard Cap | Overflow Action |
|------|--------|----------|-----------------|
| wiki/hot.md | 500 words | 600 words | Trim oldest entries |
| wiki/index.md | 40 lines | 80 lines | Archive completed entries |
| memory/pitfalls.md | 10 active | 20 active | Rotate oldest 10 |
| memory/session-bridge.md | 30 lines | 50 lines | Archive old Done items |

### Shutdown (every session end)
Update `memory/session-bridge.md`: Done / Waiting / New Pitfalls / New Discoveries

### corgi Apply → Long-term Memory
After each Task Group completes:
- New pitfalls → append to `memory/pitfalls.md` (link source change)
- New implicit rules → append to `wiki/architecture/implicit-contracts.md`
- Update `wiki/hot.md` Recent Decisions

### Compaction Triggers (agent self-maintains)
- Every archive: compress session-bridge
- pitfalls > 20 entries: rotate oldest 10 to Archive section
- hot.md > 550 words: trim oldest entries
- Every 10 corgi sessions: suggest running /corgi-lint

5. Idempotency and safety

Throughout all steps, enforce these rules:

• Never overwrite existing files. If a file already exists at the target path, skip it and add to the "skipped" report.
• Never overwrite existing protocol section. If ## Session Memory Protocol already exists in the config file, do not duplicate it.
• Only operate within the project directory. Never write to user-home or global paths.
• Report all actions. At the end, print a summary:
  • Files created (list paths)
  • Files skipped (already existed)
  • Protocol injection status (injected / already present / no config file found)
  • Next steps recommendation

6. Output summary

Print a structured summary:

## Memory Init Complete

**Project**: <name>
**Created**: N files
**Skipped**: M files (already existed)
**Protocol**: Injected into <file> / Already present / No config file

### Created Files
- memory/MEMORY.md
- memory/session-bridge.md
- memory/pitfalls.md
- wiki/hot.md
- wiki/index.md
- wiki/schema.md
- wiki/log.md
- wiki/architecture/_index.md
- wiki/architecture/implicit-contracts.md
- wiki/patterns/_index.md
- wiki/research/_index.md
- wiki/sessions/_index.md
- wiki/decisions/_index.md
- wiki/questions/_index.md
- wiki/meta/_index.md

### Next Steps
1. Review `memory/MEMORY.md` — fill in any placeholders
2. Run `/corgi-propose` to create your first change
3. Memory will auto-update during apply and archive phases

Common Mistakes

• Overwriting existing memory files (violates idempotency)
• Injecting Session Memory Protocol twice
• Using absolute paths instead of project-relative wikilinks
• Forgetting to extract project identity before writing templates
• Writing outside the target project directory
