v0.9.0: Telemetry and injection-path hardening

Two injection paths into the enforcement surface are closed, one of them Critical: a prompt-injected agent could skip the governance approval gate entirely, and the signed attestation would still record governance: pass. If you run enforce=True, upgrade.

This release also adds anonymous usage telemetry, enabled by default. That is why this is a minor and not a patch. The opt-out is below. We would rather you meet it here than find it in a packet capture.

Important

Telemetry is on by default in 0.9.0. It is anonymous and shape-only (enum values, counts, rounded scores, durations) and never carries prompts, tool arguments, agent names, file paths, or any other content. If you would rather not send it, opt out before upgrading:

export DO_NOT_TRACK=1                      # the cross-tool standard, or:
export AGENTEGRITY_TELEMETRY_DISABLED=1    # agentegrity-specific

Every event and property is documented in docs/telemetry.md, and all payload construction lives in one auditable file: _telemetry_props.py. Read it rather than taking our word for it.

Warning

Breaking: tool-call actions nest their arguments. Custom PolicyRule conditions reading call-derived keys off the top level will silently stop matching. A rule that stops matching does not raise, it passes. See Migration from 0.8.1 below.

Install

pip install --upgrade agentegrity==0.9.0

npm install @agentegrity/client@0.9.0

All seven @agentegrity/* npm packages are published at 0.9.0.

Security

[Critical] Tool arguments could shadow the fields governance matches on

The attack, first:

# Before 0.9.0: this skipped GOV-001's approval gate entirely
agent_calls("payment_execute", {"tool": "noop"})

The pre_tool_use buffer entry was built by spreading the agent's own arguments over the trusted fields:

{"tool": tool_name, "type": "tool_call", **tool_input}   # the bug

That entry becomes context["action"]. So an argument named tool overwrote the real tool name, and GOV-001's sensitive-tool gate evaluated the forgery instead of the actual call. The same trick overrode type.

Both deployment modes were affected, and both outcomes are bad:

• Under enforce=True, the dangerous tool ran with no approval.
• In observe-only mode, the signed attestation recorded governance: pass for a check that never happened. The audit trail asserted a guarantee it had not verified, which is worse than recording a failure.

Untrusted arguments now nest under action["arguments"], where no agent-controlled key can collide with a trusted field.

[High] The LLM classifier skipped the two multi-agent channels

The regex scanner covers seven channels. AdversarialLLMLayer.aevaluate fed only five to the classifier, so shared_memory and broadcast_channels reached neither strong detector.

That gap matters more than a missing code path suggests. We publish that the regex taxonomy scores 0.000 TPR on InjecAgent (N=2,108) against action-oriented injections, which is exactly the traffic those channels carry. So "neither detector" meant no effective coverage at all, on the one surface a compromised peer writes to.

This is the cross-agent cascade (T-CASCADE) that the v0.8 channels exist to defend. A compromised peer's injection into shared memory passed clean. Both channels are now classified, using the same content keys and channel labels as the regex scanner.

Added

Anonymous, shape-only usage telemetry. The client, monitor, chain verification, and CLI emit anonymous usage events to guide adapter and evaluation-surface priorities.

What it sends: enum values, counts, rounded scores, durations. What it never sends: prompts, model inputs or outputs, tool arguments, file paths, agent names, or any other content.

• Stdlib-only sender. No new dependencies.
• Telemetry failures can never reach the host process.
• Nothing is sent on import.
• A random, resettable UUID at ~/.agentegrity/id is the only identifier.
• When disabled, nothing is written, no thread starts, and no network is touched.

Three ways to opt out:

export DO_NOT_TRACK=1
export AGENTEGRITY_TELEMETRY_DISABLED=1

import agentegrity
agentegrity.disable_telemetry()

Changed

LLM classification cost is bounded. aevaluate issued one sequential API call per target with no ceiling, while the multi-agent buffers hold up to 1000 entries per channel. On attacker-writable content, that is both a latency tail and a cost-amplification lever.

• Bounded concurrency (max_concurrency, default 8).
• Per-evaluation target ceiling (max_targets_per_evaluation, default 200).
• Truncation is logged and reported as details["llm_classifier"]["targets_dropped"], so a capped scan never reads as full coverage.
• Verdicts are cached per (channel, content hash), so growing buffers stop re-billing text already classified, and duplicate text within a single evaluation is classified once.
• Every reuse is reported (reused_verdicts, llm_calls) so the skipped calls stay visible too.
• Fail-open verdicts are never cached: they record an outage, not a judgment.

Migration from 0.8.1

Tool-call actions nest their arguments.

# 0.8.1
{"tool": "transfer", "type": "tool_call", "amount": 50000}

# 0.9.0
{"tool": "transfer", "type": "tool_call", "arguments": {"amount": 50000}}

Custom PolicyRule conditions reading call-derived keys off the top level must read them from action["arguments"]. Rules matching only tool or type are unaffected.

The built-in GOV-003 financial rule was updated accordingly: it reads action["arguments"]["amount"] and no longer honors a top-level amount.

Grep your custom rules before you deploy. A rule that no longer matches fails open and silently, so this will not surface as an error. It will surface as an approval gate that quietly stopped firing.

Also in this release

A README claim was wrong, and is now fixed. The "What it does" section still said the library "never makes network calls to Cogensec or any other service" while the same file documented default-on telemetry. Both statements cannot be true. The paragraph now states plainly that evaluation runs locally, that no agent content leaves your process, that shape-only telemetry is the one outbound call, and it links the opt-out.

Design Principle #6 says every claim the library makes is defensible in writing. That one was not, and shipping a release with it intact would have been the exact failure the principle exists to prevent.

Roadmap renumbered. v0.9.0 was previously reserved for Federation + fleet. That work moves to v0.10.0: FederationLayer at pipeline position 0, the Coordination Integrity property, KeyProvider with per-agent attestation chains, and the fleet aggregator for population posture.

Why a minor and not a patch

Semantic versioning reserves patch releases for backwards-compatible fixes. This release adds a capability that is on by default and makes the library's first outbound network call, and it changes a public contract in a way that fails silently. Neither belongs behind a patch number, and burying a default-on phone-home in one is how projects lose trust they spent years earning.

There is a coupling worth naming: the Critical fix and the telemetry ship together. If you want the security fix without the telemetry, set DO_NOT_TRACK=1 and you get exactly that.
