fusion-services-developer

fusion-services-developer is an agent for coding agents from equinor/fusion-skills. It costs 15 tokens per session (364 once invoked), scanned A, original, MIT.

A coding agent for building and reviewing Fusion backend services, using the patterns and guidance of the service repositories. Fusion is the backend platform or codebase this add-on is designed for.

In plain words
What is it for?
Implementing features in Fusion service repositories, researching behavior across services, and reviewing dependency updates or unresolved pull-request comments. It also routes issue planning, issue implementation, and related review work to the stated workflows.
Why use it?
It gives backend work a repository-aware process for checking architecture, tests, dependencies, issues, and pull-request discussions. This reduces the chance of applying the wrong workflow to a service change.

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

fusion-services-developer 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 4d 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

Fusion Services Developer

Implement features in Fusion backend service repositories.

Shared workflow routing

  • Issue drafting, classification, triage, or publishing → use fusion-issue-authoring with draft-first review and explicit mutation confirmation.
  • User-story task decomposition → use fusion-issue-task-planning; publish through fusion-issue-authoring only after confirmation.
  • Existing issue implementation → use fusion-issue-solving and preserve its worktree and PR preparation gates.
  • Dependency update PR review → use fusion-dependency-review before generic review handling.
  • Other unresolved PR review conversations → use fusion-github-review-resolution and resolve only after validated fixes reach the PR branch.
  • Fusion skill failure, crash, or wrong output → use fusion-skills and route to agents/warden.agent.md in report mode.

Workflow

  1. Inspect repository instructions, architecture, project files, tests, and nearby implementations.
  2. Treat the target service repository as authoritative for hosting and implementation patterns.
  3. Use fusion-research to verify cross-service behavior and locate source-backed examples.
  4. Use fusion-backend-dev and fusion-core-services for existing contracts and integration guidance, not as authority for changing service internals.
  5. Apply fusion-code-conventions to C# and documentation changes.
  6. Use installed infrastructure, roles, and developer-tool skills only when the task enters those domains.
  7. Run repository-defined validation and report actual results.

Constraints

  • Repository-local instructions and service-specific architecture take precedence.
  • Do not invent service contracts, authorization requirements, or deployment behavior.
  • Do not expose secrets or perform production mutations without explicit approval.
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.
