time-bomb-radar

time-bomb-radar is a skill for Claude Code from Terryc21/radar-suite. It costs 80 tokens per session (11,004 once invoked), scanned A, original, Apache-2.0.

A code review tool for finding failures that appear only after stored data becomes old or reaches a time limit. Examples include expired caches, expired trials, delayed deletions, and scheduled actions.

In plain words
What is it for?
Auditing deferred deletions, cache expiry, trial expiry, background accumulation, date-based transitions, and other operations triggered by aging data.
Why use it?
Normal tests often use fresh data, so they can miss bugs that happen weeks or months later. It helps identify these delayed failure paths before they affect long-running users.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

time-bomb-radar scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Time Bomb Radar

Finds code that works today but crashes after the data gets old enough.

Time bombs are deferred operations that pass every test, every code review, every pattern matcher, then crash your app weeks or months after release. The trigger is data age + environment state, not code paths. They produce 1-star reviews from your most loyal users -- the ones who kept the app long enough for the timer to fire.

Origin: A production-class crash where SafeDeletionManager archived items for 30 days, then cascade-deleted them, triggering a SwiftData _FullFutureBackingData fatal error on unresolved iCloud .externalStorage faults. The bug was invisible during development because no test data was 30 days old. If shipped, every user would have crashed on day 31.

Quick commands

Command What it does
/time-bomb-radar Full audit across all 7 patterns
/time-bomb-radar deferred-deletes Pattern 1 only -- cascade deletes on aged data
/time-bomb-radar cache-expiry Pattern 2 only -- cache purge with model relationships
/time-bomb-radar trial-expiry Pattern 3 only -- subscription/trial expiry paths
/time-bomb-radar background-tasks Pattern 4 only -- accumulated background work
/time-bomb-radar date-transitions Pattern 5 only -- date-threshold state changes
/time-bomb-radar scheduled-side-effects Pattern 6 only -- notifications/reminders scheduled from aged data
/time-bomb-radar cascade-live-refs Pattern 7 only -- cascade delete with live child references
--show-suppressed Show findings suppressed by known-intentional entries (see § Intentional Suppression Flags)
--accept-intentional Mark current finding as known-intentional (see § Intentional Suppression Flags)

Intentional Suppression Flags

Both flags wrap the protocol in radar-suite-core.md § Known-Intentional Suppression, which owns the canonical spec for .radar-suite/known-intentional.yaml (file format, fields, matching rules).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
