Snapshot

Snapshot — /snapshot

What this skill does

When the user types /snapshot, read the entire conversation and produce a single copy-pasteable block that preserves all critical context — so they can open a new chat and pick up exactly where they left off, without re-explaining anything.

How to generate the snapshot

Step 1 — Read the full conversation

Scan every message before writing a single word of output.

Step 2 — Extract critical elements

Look for:

• Project context: name, stack, language, frameworks, environment, repo
• Main goal: what was being built or solved
• Key decisions: architecture choices, libraries picked, alternatives rejected and why
• Essential code: central functions, data structures, configs, API contracts
• Problems & fixes: bugs hit, errors seen, workarounds applied
• Current state: what's working, what's broken, what's untouched
• Next steps: anything explicitly agreed upon or left pending
• Sensitive data screening: STRICTLY IDENTIFY AND IGNORE all API keys, access tokens, passwords, and sensitive credentials.

Step 3 — Write the output block

Use exactly this format — no extra commentary before or after:

## 📸 Session Snapshot

**Project:** [name / one-line description]
**Stack:** [languages, frameworks, key tools]
**Goal:** [what was being built or solved]

---

### What we did

• [Bullet 1 — critical decision or action, self-contained with enough context to never need re-asking]
• [Bullet 2 — ...]
• [Bullet 3 — ...]
• [Bullet 4 — ...]
• [Bullet 5 — ...] ← minimum 5
• [Bullet 6 — ...] ← include if there's relevant content
• [Bullet 7 — ...] ← include if there's relevant content

---

### Current state
[2–4 lines: what's working, what's pending, what's broken]

---

### Essential code
```[language]
[Only the most critical snippet — key function, data structure, config, or API shape.
Omit this section entirely if no code is relevant.]
```

---

### Security Note
[Include ONLY IF sensitive data like API keys/tokens were shared in the session but skipped:]
> ⚠️ **Notice:** Chaves sensíveis (API keys, tokens, etc.) foram compartilhadas na sessão original, mas foram ignoradas e removidas na criação deste snapshot por motivos de segurança.

---

### Agreed next steps
• [Next step 1]
• [Next step 2]

---
> Paste this block at the top of your next chat to continue right where you left off.

Quality rules

• Every bullet must be self-contained — someone reading it cold should have full context, no guessing.
• Be specific — use real file names, function names, variable names, error messages. Never generalize.
• Decisions need reasons — if something was rejected, say why (e.g., "dropped Redux for Zustand — too much boilerplate for this scope").
• Code only if essential — don't paste everything; only what a new chat would need to avoid rework.
• No filler — never write "we did several interesting things". Be direct and dense.
• Privacy first — NEVER include API keys, passwords, or sensitive credentials in the snapshot.
• Match the user's language — if they wrote in Portuguese, snapshot in Portuguese. If English, English.
• Bullet length — 1–3 lines each. No sub-bullets.

---

Short session handling

If the session has fewer than 3 meaningful exchanges or no substantial technical content, respond with:

"The session is too short for a useful snapshot yet. Keep working and run /snapshot again when there's more to capture."

Example: bad bullet vs. good bullet

❌ Bad:

• We worked on authentication and fixed some issues.

✅ Good:

• Implemented JWT auth with refresh tokens — access token expires in 15min, refresh in 7 days. Refresh token is stored in an httpOnly cookie (not localStorage) to prevent XSS. Refresh endpoint is POST /api/auth/refresh. Rejected session-based auth because the app is stateless.
