What is supervisor-specs?

A specification for a software supervisor that assigns work to coding agents and checks their results. It defines required goals, acceptance criteria, saved state, validation, and stopping conditions.

Use it when designing or operating an agent supervisor that must be explicit, restartable, and controlled by an operator.

It prevents agents from inventing tasks, expanding the scope, retrying silently, or making changes without review.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00167	$0.00167
Opus 5.5	$0.00067	$0.00067

Security

Grade A, and why

supervisor-specs 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 today.

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.

Origin

This is a copy

100% identical to supervisor-specs — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Supervisor Specifications

The supervisor does not define goals.
Operator must inject goals.
Scope cannot be expanded by AI.
All tasks require explicit acceptance criteria.
No task runs without validation.
No refactoring without explicit instruction.
State must be persisted after every step.
Ambiguity halts execution.
Cursor CLI is a worker tool, not decision authority.
AUTO MODE is default and mandatory.
AUTO MODE cannot be disabled without operator instruction.
No silent retries.
All outputs are reviewable (diffs, logs).

Anti-Goals (Do NOT Implement)

Autonomous goal refinement
Speculative task creation
Retry heuristics
AI-based validation
"Helpful" corrections
Fallback behaviors

If tempted → HALT.

Changes

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.
