For engineers

The core verbs, in full. Real commands, real output.

Every example below runs read-only against live cloud state and returns structured output you can render however you want. These five are the everyday verbs; Solon also ships the identity and reachability verbs (path-analysis, escalation-paths, compromise-reachability) that trace who and what can reach what across network and identity. Solon advises; you apply. It never touches your cloud.

One agent loop

One read-only loop.
Every verb rides it.

ask drives the agent. audit and recommend are templated wrappers over ask; change-package and architect add their own grounded emit and citation discipline. The identity and reachability verbs (path-analysis, escalation-paths, compromise-reachability) run over the same loop to trace access across network and identity. Every verb shares the grounding and citation registry and returns structured output you can render however you want.

Flags

The flags you will reach for.

--strictfail on any ungrounded citation

--model <id>swap the Claude model
Examples

The five core verbs, end to end.

Each block is a real command and its grounded output. The architect example shows the honesty split: what Solon observed in your account, separated from general best-practice guidance it did not assess.

Ask

ask

Ask your cloud anything.

Audit

Check yourself before the auditor does.

Findings (Section 5, Networking):
  5.1   Ensure no NACL allows ingress from 0.0.0.0/0 to :22         PASS
  5.2   Ensure no NACL allows ingress from 0.0.0.0/0 to :3389       FAIL (acl-0a1b)
  5.3   Ensure VPC flow logs are enabled in all VPCs                FAIL (vpc-09ee, vpc-07dd)
  5.4   Ensure default security group restricts all traffic         FAIL (sg-default in vpc-04aa)
  5.5   Ensure routing tables for VPC peering are 'least access'    PASS

Change plan

change-package

A change plan with the undo already written.

solon · zsh● live
$ solon change-package "Allow web tier sg-abc to reach app tier sg-def over port 8080." --cloud 111122223333
→ Investigating read-only...
→ aws.describe_security_group_rules  count=146
→ aws.list_nacls  count=24

Pre-checks:
  • sg-abc and sg-def both exist in vpc-04aa            PASS
  • No existing rule already permits sg-abc → :8080      PASS
  • NACL acl-0a1b currently blocks :8080 between them    NOTED

Ordered change (minimal diff):
  step 1  authorize sg-def ingress  tcp/8080 from sg-abc
          back-out: revoke that ingress rule            [reversible]
  step 2  add NACL acl-0a1b allow  tcp/8080  sg-abc → sg-def
          back-out: delete the added NACL entry         [reversible]

Post-verify:
  • path sg-abc → sg-def on :8080 reachable             assert
  • no new 0.0.0.0/0 exposure introduced                assert

Architect

architect

Design it to the gold standard from day one.

solon · zsh● live
$ solon architect --goal "Harden the access posture of this account against the AWS Well-Architected Security pillar" --cloud 111122223333

→ aws.list_security_groups  count=438
→ aws.list_s3_buckets  count=52
→ playbook.load  aws-well-architected  pillar=security  SEC1..SEC11

Design recommendations (grounded on what Solon reads):
  SEC2  Reduce blast radius: 7 users hold inline "*:*" policies; move to
        scoped roles assumed via OIDC.              Cited: 7 user ARNs, policy AdminAll
  SEC5  Close 3 security groups with 0.0.0.0/0 → :22 ingress.

  SEC8  Enable default encryption on 4 public-readable S3 buckets.

General guidance (not assessed from your account):
  SEC4  Stand up centralized detection (GuardDuty, Security Hub) and route
        findings to a single account. Solon does not read detection config.
  SEC10 Define an incident-response runbook and rehearse it. Out of read scope.

Advise-only design. Solon never applies anything; you decide what to act on.
