Guardrails

Critical guardrails for Engineering agents

Ten controls that hold regardless of prompt, plan or pressure. Open one to see what it protects, what trips it, what the agent is forced to do, who may release it, and what is written to the record.

GR-01No production mutation without change-ticket approvalOverride defined▸

Target

Production databases, deployments, force-pushes, deletions and infrastructure state across live environments.

Trigger

Any write, delete or deploy targeting a production resource without an approved change ticket.

Action — enforced

Platform blocks execution, converts the step to a staged plan, and requires the ticket reference before release.

Human override

Release manager via approved change ticket linked in the deploy pipeline.

Logged evidencechange ticket id · target resource · diff hash · approver identity · execution timestamp · rollback plan id

GR-02No agent egress beyond the sandbox allow-listNo override▸

Target

Network calls, file writes and artifact uploads from agent sandboxes and CI runners.

Trigger

Traffic or file output addressed outside the pinned per-task allow-list.

Action — enforced

Platform drops the connection, freezes the sandbox for forensics, and lets the task resume only on allow-listed destinations.

Human override

None — cannot be overridden in session

Logged evidencesandbox id · destination address · payload size and hash · task id · freeze timestamp

GR-03No instruction embedded in repo content, issues or PRs executedNo override▸

Target

Source files, README text, issue threads, PR descriptions and instruction files agents ingest.

Trigger

Directive text or hidden-Unicode payloads detected in repository or tracker content.

Action — enforced

Platform treats the content as data only, quarantines the artifact, and blocks writes to agent memory and instruction files.

Human override

None — cannot be overridden in session

Logged evidenceartifact hash · payload excerpt · repo and ref · quarantine id · scanner version

GR-04No plaintext secret in code, logs or answersOverride defined▸

Target

Generated code, commit diffs, CI logs, chat answers and artifact stores agents produce.

Trigger

A credential-pattern match in any agent output before write or send.

Action — enforced

Platform redacts the match, blocks the commit or reply, and opens a rotation task for the exposed credential.

Human override

Security engineer via confirmed false-positive disposition in the secret scanner.

Logged evidencedetection id · secret fingerprint · output channel · rotation ticket · block timestamp

GR-05No unreviewed edit to CI workflow definitionsOverride defined▸

Target

Pipeline YAML, branch-protection rules, runner permissions and check configurations in every repo.

Trigger

An agent-authored change touching workflow files, permission scopes or required checks.

Action — enforced

Platform splits the change into a separate PR, requires platform-team review, and blocks self-merge by any agent identity.

Human override

Platform engineering lead via CODEOWNERS-enforced review on the workflow PR.

Logged evidencePR id · workflow diff hash · permission delta · reviewer identity · merge timestamp

GR-06No tool call on a mutated tool manifestOverride defined▸

Target

MCP servers, tool descriptions, skills and connectors registered for agent use.

Trigger

A manifest hash differing from the version approved at registration time.

Action — enforced

Platform refuses the call, disables the tool fleet-wide, and requires re-approval of the changed manifest by security.

Human override

Security engineering via re-pinned manifest approval in the tool registry.

Logged evidencetool id · approved hash · observed hash · disable timestamp · re-approval record

GR-07No export-controlled data sent to external modelsOverride defined▸

Target

ITAR and EAR technical data, controlled designs and trade-secret material in prompts or uploads.

Trigger

A classification tag or control marking detected in content bound for an external endpoint.

Action — enforced

Platform blocks the transfer, keeps processing on approved in-boundary models, and notifies the export-control officer.

Human override

Export-control officer via documented licence determination for the specific dataset.

Logged evidencecontent classification · destination endpoint · block timestamp · requester identity · determination reference

GR-08No dependency added without registry provenance verificationOverride defined▸

Target

Package manifests, lockfiles, imports and build scripts across all repositories.

Trigger

A suggested package absent from the approved registry or below the age-and-adoption floor.

Action — enforced

Platform blocks the install, checks the name against known-good packages, and proposes a vetted alternative in the PR.

Human override

Staff engineer via allow-list addition recorded with a provenance review.

Logged evidencepackage name and version · registry check result · typosquat distance · PR id · approver identity

GR-09No closure of exploitable findings without sign-offOverride defined▸

Target

SAST, DAST, dependency and pentest findings in the vulnerability queue.

Trigger

An agent disposition of not-exploitable or wontfix on a finding above severity threshold.

Action — enforced

Platform holds the closure, requires a security engineer’s sign-off with rationale, and keeps the finding open meanwhile.

Human override

AppSec lead via documented risk acceptance with an expiry date.

Logged evidencefinding id · severity · proposed disposition · sign-off identity · rationale hash · expiry date

GR-10No merge without meaningful human review attestationOverride defined▸

Target

Agent-authored pull requests to protected branches across product and infrastructure repositories.

Trigger

A merge attempt where review time, diff coverage or comments indicate rubber-stamping.

Action — enforced

Platform blocks the merge, records model, prompt and context versions, and assigns a second reviewer with a review checklist.

Human override

Engineering manager via attested review confirmation on the pull request.

Logged evidencePR id · reviewer identity and dwell time · model and prompt versions · checklist result · merge timestamp

Oversight

Human review — triggers, decisions and evidence

When a defined risk trigger fires, the affected action is routed to a named reviewer. Every decision is recorded with its correction, escalation and final outcome for full traceability.

Department lead review

For applicable high-risk agents, the client’s designated department leader reviews the evaluation criteria and pass thresholds before baseline approval.

Test-case rotation

Evaluation cases are refreshed regularly to reduce memorisation and maintain reliable performance measurement.

Scorecard integration

Scorecards track results against the approved baseline and flag material declines for review and escalation.

Department-specific extensions

Where included in scope, evaluations may be expanded using approved workflows, tools, templates, policies, and incident history.

Monitoring

Change-aware monitoring

When agent performance changes, Nestack correlates the shift with changes to the agent, prompt, model, tools, knowledge base, guardrails and evaluation suite.

Something missing?

Don’t see your agent’s issue here?

Every AI environment is different. Share what you’re seeing, and we’ll review the behaviour, assess the risk and recommend the evaluations or controls that may help.

No commitment. Even if you never become a client, we’ll tell you what we think is happening.

Process

Universal incident runbook

Severity is assigned based on business impact, customer harm, data exposure, operational disruption and overall scope.

Severity scaleSEV-1 Critical SEV-2 Major SEV-3 Moderate SEV-4 Minor

Detect

Automated monitoring or human review identifies unusual behaviour. Alerts are recorded and routed according to severity.

Contain

For critical incidents, agreed actions may restrict autonomy, pause affected workflows, or switch the agent to a safer operating mode.

Diagnose

Review available logs and traces, classify the incident, and estimate the affected scope, duration, and business impact.

Remediate

Apply the agreed corrective action, validate the change through targeted testing, and recommend when normal operation can resume.

Notify

Inform the client according to the agreed response target, including known impact, actions taken, current status, and next steps.

Learn

Review significant incidents, document lessons learned, and update evaluations, controls, or procedures where appropriate.

Cost control

Keep engineering / r&d AI agent costs under control

Token spend is monitored, optimised and reported as part of Agent Care — and savings never come at the expense of quality, because every change is verified against your evaluation baseline.

Cost visibility per agent

We review token spend by agent, workflow, model, and session so you can understand where AI costs are coming from.

Cost-anomaly review

We watch for unusual spend patterns such as retry loops, long-running sessions, repeated calls, and sudden usage spikes.

Model right-sizing

We recommend where lower-cost models can support routine tasks, while keeping stronger models for complex or high-risk workflows.

Caching & reuse opportunities

We identify repeated questions, stable answers, and reusable context that may be handled without unnecessary fresh model calls.

Prompt & context optimization

We review prompts, retrieved context, repeated instructions, and long histories to find practical token-saving opportunities.

Budget guardrails & reporting

We help define per-agent budget thresholds, cost alerts, and monthly spend summaries so AI bills stay easier to manage.
