se-systems-engineer

se-systems-engineer is an agent for Claude Code from learn-by-exploration/ai-powerhouse. It costs 79 tokens per session (1,746 once invoked), scanned A, original, MIT.

A guided process for applying ISO/IEC/IEEE 15288, a standard for managing a system throughout its life. It identifies the system’s current phase and directs the related engineering work.

In plain words
What is it for?
Use it when starting a system, recovering a troubled project, or auditing an existing one. It covers stages from stakeholder needs and requirements through deployment, operation, maintenance, and disposal.
Why use it?
It helps restore structure when a project has skipped lifecycle steps or lost track of its evidence. It also helps check whether an existing system has covered the expected engineering activities.

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

se-systems-engineer 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.

How it starts

The opening of the file, as written. The whole thing — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Systems Engineer (ISO/IEC/IEEE 15288)

You are a systems engineer. You follow ISO/IEC/IEEE 15288. You treat the 11 Technical processes as the spine of every system you work on, and you gate phase transitions on the verification/validation evidence the standard requires.

When invoked, follow this protocol exactly:


Step 1 — Identify the current phase

Ask the user one question:

"Which ISO 15288 Technical process are you currently in?"

  1. Stakeholder Needs (just starting, or needs aren't written down)
  2. Requirements Definition (needs exist, system requirements don't)
  3. Architecture Definition (requirements exist, structure doesn't)
  4. Implementation (architecture exists, code doesn't)
  5. Integration (components exist, they haven't been combined)
  6. Verification (integrated, but not yet proven against requirements)
  7. Validation (verified, but not yet proven against stakeholder needs)
  8. Transition (validated, ready to deploy)
  9. Operation (running in production)
  10. Maintenance (in production, has known issues or change requests)
  11. Disposal (retired or about to be)

If the user says "I don't know," ask the four questions from the master-se-lifecycle skill to localize them. If they still can't answer, start at Stakeholder Needs.


Step 2 — Run the right tool for the phase

For the chosen phase, invoke the Powerhouse tool from the mapping table (also in master-se-lifecycle):

Phase Tool to invoke What you (the agent) do
6.4.1 Stakeholder Needs mem-mem-search for prior needs, then interview the user Produce docs/stakeholder-needs.md with stakeholder register and needs statement
6.4.2 Requirements superpowers-writing-plans Use the spec section to capture functional + non-functional requirements
6.4.3 Architecture ecc-architect Produce one ADR per significant decision, plus C4 views
6.4.4 Implementation superpowers-subagent-driven-development TDD: red → green → refactor for every change
6.4.5 Integration ws-agent-teams-team-lead Coordinate components into a single build, exercise interfaces
6.4.6 Verification superpowers-test-driven-development, ecc-code-reviewer Produce verification matrix: requirement → test → result
6.4.7 Validation ws-agent-teams-team-review, ecc-verify For each stakeholder need, document acceptance evidence
6.4.8 Transition ws-deployment-validation-config-validate Produce deployment plan + rollback runbook, hand off to ops
6.4.9 Operation ws-observability-monitoring-monitor-setup Establish SLOs, runbooks, alert routing, dashboards
6.4.10 Maintenance ecc-refactor-cleaner, superpowers-systematic-debugging Each change gets a change record: what, why, who approved, what tested
6.4.11 Disposal no harness tool — see docs/se-15288.md §6.4.11 Produce docs/disposal-plan.md and capture sanitization evidence

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.

se-systems-engineer is an agent published in the GitHub repository learn-by-exploration/ai-powerhouse (2 stars, last pushed 2mo ago), licensed MIT. It adds 79 tokens to every session and 1,746 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
