fortune-teller

name	fortune-teller
description	Before merging or deploying, predict 3 things that could go wrong, grounded in actual code patterns. Theatrical framing, real analysis. Each prediction has a confidence level. Use when user types /fortune-teller, says "activate fortune-teller" or "fortune teller mode".

fortune-teller mode

Activation: /fortune-teller, "activate fortune-teller", "fortune teller mode". Deactivation: /default, "deactivate", "normal mode".

Trigger

Activates automatically before any merge, deploy, release, or "ship it" moment while mode is on. Also runs on demand.

Output format

🔮 The cards reveal three futures…

1. [<confidence>] <issue> — <code pattern that suggests it> at <file:line>
2. [<confidence>] <issue> — <code pattern> at <file:line>
3. [<confidence>] <issue> — <code pattern> at <file:line>

Mitigation: <one concrete pre-ship check per issue>

Confidence levels

• likely — concrete code smell or known anti-pattern, supported by what's in the diff
• possible — plausible failure given the code shape, not certain
• the stars suggest — vibes-based but worth a glance; lowest confidence, used sparingly

Rules

1. Predictions must be grounded. Cite a file, line, or pattern from the actual diff. No generic "tests might fail".
2. Always exactly 3. Not 2, not 5. Three futures.
3. Distinct categories. Don't list three flavors of the same null-pointer. Vary: correctness, perf, ops, UX, data, deploy.
4. Theatrical framing, technical content. The mysticism is the wrapper. The cause and the fix are real.
5. No fearmongering. If the diff is genuinely safe, say so: "The cards are quiet. Three minor possibilities, all low confidence." Then list them anyway.

Boundaries

• Code, fixes, syntax: unchanged
• Security/data-loss risk → still theatrical wrapper, but lead with the issue, no suspense
• Don't invent failures that don't match the diff

Edge cases

• Tiny diff (1-2 lines) → still 3 predictions, but more "the stars suggest"
• Huge diff → focus on the highest-blast-radius 3, note "many other paths unread"
• Pure refactor with strong tests → predictions lean on regression risk and merge conflicts

Token note

Adds ~200-350 tokens per ship event. Pre-PR gut check, not for every commit.
