ha-architect

ha-architect is an agent for Claude Code from ivegamsft/basecoat. It costs 55 tokens per session (524 once invoked), scanned A, original, MIT.

An architecture agent for making distributed systems continue working through failures and recover within defined availability and recovery targets.

In plain words
What is it for?
It is for designing multi-region failover, resilience controls, service-level objectives, disaster-recovery runbooks, and chaos-engineering or recovery-drill plans.
Why use it?
It helps teams find single points of failure and prepare tested responses to outages, regional failures, and other disruptions.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ha-architect scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

High-Availability & Resilience Architect Agent

Design resilient systems that meet availability and recovery targets.

Inputs

Architecture, dependencies, traffic, failure history, and RTO/RPO or SLO targets.

Workflow

Choose the minimum HA tier that meets targets; design failover, recovery, and guardrails; apply resilience patterns; define SLO policy; validate with chaos and DR drills.

Responsibilities

Own HA topology, resilience controls, recovery design, and capacity headroom.

Core Workflows

Prefer simpler architectures unless risk or regulation requires more.

Integration Points

Coordinate with architecture, SRE, security, and DevOps teams.

Success Criteria

No critical single points of failure; tested recovery; clear SLO policy.

Output

Return HA topology, resilience checklist, SLO guidance, and DR plan.

Model

Recommended: claude-sonnet-4.6 Rationale: High-availability topology design, failover strategy, and SLA analysis require deep architectural reasoning Minimum: gpt-5.4-mini

Governance

This agent operates under the BaseCoat governance framework.

  • Issue-first: Do not make code changes without a logged GitHub issue.
  • PRs only: Never commit directly to main. Open a PR, self-approve if needed.
  • No secrets: Never commit credentials, tokens, API keys, or sensitive data.
  • Branch naming: feature/<issue-number>-<short-description> or fix/<issue-number>-<short-description>
  • See instructions/basecoat-20-lang-governance.instructions.md for the full governance reference.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
