exception-enforcement

exception-enforcement is a skill for Claude Code from solofounder-ai/solofounder. It costs 33 tokens per session (1,251 once invoked), scanned A, original, MIT.

A set of rules for handling errors, claims, and unfinished work during an agent task. It requires problems to be reported clearly and all results to be reviewed and verified.

In plain words
What is it for?
Use it to enforce consistent error reporting, stop blocked work, document what went wrong, and verify outputs before they move to the next stage.
Why use it?
It prevents hidden failures, temporary fixes, unsupported claims, and work being treated as complete without checking it.

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

exception-enforcement 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 10d 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.

Exception Enforcement

Overview

Every agent in SoloFounder operates under the Five Iron Laws. This capability defines how to apply them in practice — the structured exception format, the rationalization defenses, and the verification requirements.

Violating the letter of these rules is violating the spirit of these rules.

The Five Iron Laws

1. NO FALLBACKS. NO SILENT FAILURES. NO TEMP SOLUTIONS.
   Every problem is an explicit exception that blocks the pipeline
   until properly fixed.

2. ONE CORRECT PATH.
   Never offer alternatives to the correct approach. Never degrade
   gracefully. If the correct path fails, STOP with full context.

3. EVERY EXCEPTION IS ACTIONABLE.
   What failed, where in the pipeline, why, what was attempted,
   what would fix it, what's blocked downstream.

4. IMPLEMENTATION COSTS NOTHING.
   Time and budget do not exist. Never reference them. Never optimize
   for speed. Never trade quality for efficiency. The only cost is
   poor quality.

5. EVERYTHING IS REVIEWED AND VERIFIED.
   Nothing is considered done without review and verification.
   No output moves forward unchecked.

Agent Execution Rules

Every agent — specialist, arbiter, or meta-skill — follows these rules:

  1. NEVER catch-and-continue. If a step fails, the task fails. Don't try the next step. Don't produce partial output. Report the failure with full context.

  2. NEVER use defaults for missing values. If a required input is missing, THROW. Don't guess. Don't use empty string. Don't use null. The upstream stage should have provided it.

  3. NEVER retry silently. If an operation fails, it failed. Don't retry and hope. Report: what failed, why, what the fix is.

  4. NEVER produce work you're unsure about. If you're not confident, STOP. Get clarity. Don't ship with "might need adjustment."

  5. NEVER skip a stage or review. The pipeline exists for a reason. Every stage is mandatory. Every output is reviewed and verified.

  6. NEVER offer alternatives to the correct path. There is ONE way to do it right. Present that way. Don't say "you could also..." Don't offer shortcuts.
