assumptions

Manage assumptions: $ARGUMENTS

Commands

Parse the first word of $ARGUMENTS to determine the command:

list — Show all tracked assumptions

1. Read all .assumptions/*.jsonl files
2. Parse each line as a JSON record
3. Display sorted by confidence (lowest first) or staleness (oldest verification first)
4. Format as a table: ID | Category | Claim | Confidence | Last Verified | Status

add — Register a new assumption

Parse remaining arguments for: --category, --claim, --evidence, --source

Create a new assumption record in .assumptions/registry.jsonl:

{
  "id": "<category>-<short-slug>",
  "category": "<api|dependency|behavior|environment|tooling>",
  "claim": "<what we assume to be true>",
  "evidence": "<what supports this assumption>",
  "source": "<where this was discovered>",
  "confidence": 0.8,
  "created": "<ISO 8601>",
  "last_verified": "<ISO 8601>",
  "verification_method": "<how to test this>",
  "failure_history": [],
  "status": "active",
  "blast_radius": "<what breaks if this assumption is wrong>"
}

verify — Re-verify an assumption

1. Read the assumption record by ID
2. Execute the verification method (may involve web search, API calls, or code checks)
3. Update last_verified timestamp and confidence score
4. If verification fails, add to failure_history and reduce confidence
5. If confidence drops below 0.3, mark status as suspect and warn

stale — Show assumptions that need re-verification

1. Read all assumption records
2. Filter to those where last_verified is more than 14 days ago
3. Sort by blast_radius (highest first)
4. Display with suggested verification actions

seed — Seed registry from MEMORY.md gotchas

1. Read MEMORY.md
2. Extract entries from "Gotchas", "Known Bugs", and "MCP Knowledge API Gotchas" sections
3. For each entry, create an assumption record with:
   • category: inferred from content (api, dependency, behavior, etc.)
   • claim: the gotcha statement
   • evidence: "Discovered empirically" + date from MEMORY.md
   • confidence: 0.9 (verified by experience)
   • verification_method: suggested test
