Mcp server stress

/mcp-server-stress $ARGUMENTS

Maintainer-only repo-local alias for /mcp-server-surface-test --output-mode=fragments. Routes to the canonical audit prompt at ${CLAUDE_PLUGIN_ROOT}/skills/mcp-server-surface-test/prompts/full.md with fragments-mode emission so findings produce <audited-repo-root>/backlog.d/<finding-id>.md files for the /backlog-intake pipeline.

What this skill does

Invoke /mcp-server-surface-test --output-mode=fragments against the current Claude Code session's repo root (the only path the Roslyn MCP server's sanctioned-root restriction permits — see Limitations below). Forward any additional flags (--no-worktree, --single-agent, --quick) verbatim.

Why this skill exists (and why it's a thin alias)

Before v1.X.Y, /mcp-server-stress used a separate maintainer-overlay.md prompt that duplicated ~85% of full.md while adding three repo-coupled phases (backlog.d/ fragment emission, ai_docs/audit-reports/ report path, ai_docs/backlog.md regression cross-check). Every prompt fix had to be applied to both files, and they drifted in subtle ways.

The v1.X.Y refactor folded the maintainer-overlay's unique content into full.md behind:

• --output-mode=fragments → Phase 19 emits backlog.d/ fragments (the maintainer-overlay's Phase 19 behavior).
• Auto-detection of ai_docs/audit-reports/ vs audit-reports/ → reports land in the maintainer's doc-audit schema location when that schema exists, top-level otherwise.
• Auto-detection of ai_docs/backlog.md vs backlog.md for regression source → Phase 18's "prior source" probe handles both.

/mcp-server-stress survives as a 1-line alias because:

1. Muscle memory. The maintainer types /mcp-server-stress reflexively; renaming to /mcp-server-surface-test --output-mode=fragments everywhere is friction.
2. Repo-local discoverability. This skill is only available from Claude Code sessions rooted in Roslyn-Backed-MCP (per .claude/skills/ discovery). The repo-local placement signals that fragments-mode is the maintainer-standard invocation.

Invocation

The skill body delegates entirely to /mcp-server-surface-test. The agent should:

1. Read ${CLAUDE_PLUGIN_ROOT}/skills/mcp-server-surface-test/SKILL.md for the canonical preconditions, flag handling, and prompt-execution flow.
2. Execute that skill with --output-mode=fragments prepended to any $ARGUMENTS the operator passed.
3. The audited repo is the current Claude Code session's repo root (no --target=<path> — see Limitations).

Functionally equivalent to typing /mcp-server-surface-test --output-mode=fragments $ARGUMENTS.

Limitations

• No cross-repo --target=<path> flag. The Roslyn MCP server's workspace_load refuses any path outside the Claude Code client's sanctioned root, which is fixed at session-start time to the directory Claude Code was opened in. To audit a different repo, open Claude Code in that repo and invoke /mcp-server-surface-test --output-mode=fragments from that session (the skill is plugin-shipped, so it's available from any repo). This is a structural limitation of the MCP root-sanction model; the cross-repo --target= invocation that the prior version of this skill advertised never actually worked end-to-end and has been removed.

Hard rules (inherited from /mcp-server-surface-test)

• Server-required. No generic non-MCP fallback exists. If mcp__roslyn__server_info is not callable or connection.state is not ready, halt.
• Read-only against main. Phase 6 apply-mode mutations confine to the disposable worktree the prompt creates. Never push or merge from inside this skill.
• Mutation isolation contract. Phase 7 / 8b / 13 writes target the disposable worktree only. Run-end primary-checkout git status MUST be empty (Phase 0 baseline + Final surface closure step 3a hard gate).
• No silent truncation. Subagent phases that return skipped-budget / skipped-context / truncated markers are hard FAILs; orchestrator re-dispatches or records phase-failed-budget as P1.
• P0 / security findings never go to GitHub Issues under findings mode. Under fragments mode, area: security triggers /backlog-intake --publish's refusal contract when the fragment is later published.

Exit annotation

This skill is a thin alias and does not track its own semantic-call count. To verify that the underlying surface-test run made meaningful Roslyn tool calls, check the audit report's tool-invocation section (Phase 17 in full.md): it records the complete list of MCP tools called and their call counts for the session. If the tool-invocation section is absent or shows zero semantic calls (only infrastructure calls such as workspace_load / server_info), treat the run as potentially incomplete and re-invoke with an explicit --single-agent flag to reduce context-budget pressure.
