Ledger
Adversarial idea evaluation for Claude Code - kill bad ideas before they eat money, time, and attention. Every verdict compounds into a persistent, auditable decision ledger.

2 things to look at
- 24 days oldThe repository was created 24 days ago. New is not bad, but a brand new repository carrying a familiar-sounding name is the shape a typosquat arrives in, and there has been no time for anyone else to find a problem with it.
- 0 stars0 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.
What its author says it does
Copied from the file, not written here
Query or maintain the persistent idea ledger and pitfall priors. Use for "check the ledger", "what does my ledger say", "have I tried this before", "my pitfalls", "update my priors", or before starting any new project. Read-mostly; writes go through idea-killer verdicts or explicit user requests.

Ledger
The ledger is the user's auditable decision memory. Resolve its directory in
this order: $IDEA_LEDGER_DIR if set, else ~/.claude/ledger/.
IDEA-LEDGER.md- every idea evaluated, with verdict, failure tags, and re-entry triggers.PITFALLS.md- standing priors: failure classes with evidence tallies, plus recognition rules.
If the files do not exist, offer to initialize them from the plugin's
ledger-template/.
Answering queries
- Read both files.
- For "have I tried X" - match on the idea, its failure tags, AND its shape (same buyer, same wedge, same distribution problem). A new coat of paint on a killed shape is the same idea.
- For pattern questions - report tag tallies and Standing Priors verbatim, then interpret. Never soften a prior to be agreeable.
Maintenance rules
- New entries are appended by the idea-killer skill; do not duplicate.
- 3 KILLs sharing a tag -> promote the tag to a Standing Prior in PITFALLS.md (with the three entry ids as evidence).
- A prior can be RETIRED only by contrary external evidence (a GO that survived contact with paying users), never by argument. Record the retirement, do not delete the history.
- PARK entries: when their trigger fires, they re-enter through idea-killer, not straight to GO.
- Convert relative dates to absolute. ASCII only (no em-dashes).
- Remind the user to commit ledger changes; an uncommitted ledger is not auditable.
