The Time Capsule

Q: How do I know the The Time Capsule output is good?

The skill verifies itself against its own quality checks: Every prediction is falsifiable with its scoring criterion pre-agreed —; no "things will improve"; Confidence percentages vary; a ledger of all-70% is hedging in costume; At least one fragile-or-pretending item that would never appear in an.

🔵 Stable🕐 updated 2026-10-06 ✅ 4.8/5 🔷 SkillSpec L3 pm-2027

Write a sealed memo to your future self or successor — the honest state of things, falsifiable predictions with confidence levels, and the advice you suspect they'll need — with an open-on date and a scoring ritual for when it's opened. Use when leaving a role, finishing a big project, at year-end or planning season, before a leave, or 'write a letter to my successor'. Produces the sealed capsule, its prediction ledger, and the opening-day ritual.

What to give it

▸Who opens it — (successor, future you, the team) and roughly when (a date, or a trigger event)

▸The occasion — leaving, project end, year-end, pre-leave

▸The current state as they'd tell a trusted friend — including what's fragile, what's pretending to be fine, and what they'd do next if they stayed

▸The calls they're least sure about — those become the best predictions

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓Every prediction is falsifiable with its scoring criterion pre-agreed —

✓no "things will improve"

✓Confidence percentages vary; a ledger of all-70% is hedging in costume

✓At least one fragile-or-pretending item that would never appear in an

✓official handover

✓Advice is in if-then-because form; the permission slip exists

✓The seal has both a date and an early-open trigger, and the memo commits

✓the writer to not editing after sealing

⚠️ What it refuses to do

Do not write a legacy-polishing document — the opener scores it; vanity

ages worst of all

Do not let predictions hide in prose; the ledger table is the contract

Do not settle scores or name-blame — "the truce with X is fragile" is

information; "X is impossible" is a grenade with a delay fuse
