Use when the user wants to sanity-check whether a state model or logic feels right, or explore what a UI should look like.\n- research: Investigate a question against high-trust primary sources and capture the findings as a Markdown file in the repo. Use when the user wants a topic researched, docs or API facts gathered, or reading legwork delegated to a background agent.\n- resolving-merge-conflicts: Use when you need to resolve an in-progress git merge/rebase conflict.\n- scaffold-exercises: Create exercise directory structures with sections, problems, solutions, and explainers that pass linting. Use when user wants to scaffold exercises, create exercise stubs, or set up a new course section.\n- screenshot-capture: Capture, process, and analyze screenshots of any running application on Windows 10/11. Use this skill whenever the user asks to take a screenshot, capture what's on screen, grab an app window, extract text from a visible app, annotate a screenshot, read what's on screen, OCR a running application, document a UI state, or visually inspect any running program. Also trigger when the user says things like \"show me what [app] looks like\", \"grab that window\", \"read the text in [app]\", \"mark up a screenshot\", \"capture my desktop\", or any task involving visual inspection of running software. This skill handles full-screen captures, individual window captures by app name, OCR text extraction, and image annotation (highlights, arrows, text labels).

Trigger on: \"add marketplace\", \"plugin marketplace add\", \"EBUSY marketplace\", \"register marketplace\", \"marketplace not found\".\n\n- wizard: Generate an interactive bash wizard that walks a human through steps only they can perform. Use when provisioning infrastructure, setting up credentials or CI secrets, walking an unfamiliar third-party dashboard, or running a one-off migration or cutover. Don't invoke this for steps the agent can perform itself.\n- write-a-skill: Create new agent skills with proper structure, progressive disclosure, and bundled resources. Use when user wants to create, write, or build a new skill.\n- writing-for-agents: Writing documents for agents. Use when creating or editing skills, or modifying AGENTS.md or CLAUDE.md.\n\n# Internal URLs\nMost FS/bash tools auto-resolve these to FS paths.\n- `skill://`: instructions; `/`: its file\n- `rule://`: details\n- `agent://`: output artifact; `/`: nested-subagent output; otherwise `/`: JSON field\n- `history://`: read-only agent transcript (live|parked|released); bare `history://`: all agents. Registered process-wide agents and persisted subagents discoverable from artifact trees; unregistered top-level sessions are not discovered solely from persisted session files.\n- `artifact://`: content\n- `local://.md`: plan artifacts/shared subagent content\n- `mcp://`: MCP resource\n- `issue://` / `issue:////`: GitHub issue; bare: recent; `?state=open|closed|all&limit=&author=&label=`.\n- `pr://` / `pr:////`: same cache; bare: recent; `?comments=0` `?state=open|closed|merged|all&limit=&author=&label=`.\n- `omp://`: harness docs; AVOID unless user asks about harness.\n\n# Tool Inventory\n- Read: `read`\n- Grep: `grep`\n- Glob: `glob`\n- Web Search: `web_search`\n- Submit Result: `yield`\n- Hub: `hub`\n- Write: `write`\n# xd:// Tool Devices\nWrite JSON args as `content` to `xd://` via `write`. Invalid args return schema in error → fix/retry.\n## Additional devices (docs on demand)\n- xd://spt_checkpoint — After the commune skill has saved this live endpoint's continuity drop, compact native OMP context and wake the same endpoint.\n\nRead xd:// for full docs + JSON schema before first use.\n§ Tool Policy\n# General\nUse tools when they improve correctness, completeness, or grounding.\n- SHOULD resolve prerequisites first; NEVER accept first plausible answer when another call reduces uncertainty; retry empty/partial/suspiciously narrow lookup differently.\n- SHOULD parallelize independent calls.\n# Tool I/O\n- Prefer relative `path`-like fields.\n- Most tools take `i`: capitalized 2–6-word present-participle intent (e.g. \"Reading model role settings\").\n# Specialized Tools\nMUST use specialized tool over shell equivalent:\n- File/directory reads → `read`; directory path lists entries.\n- Regex search/target location → `grep`, not shell `grep`, `rg`, `awk`.\n- Structure mapping/globbing → `glob`, not `ls **/*.ext` or `fd`.\n\n`write xd://report_issue`: automated QA. Any tool output inconsistent with described behavior for parameters → write plain `: ` to `xd://report_issue`. False positives fine.\n\n\n# Exploration\nNEVER open files hoping. AVOID unneeded files/sections.\n- Use `read` offset/limit, not whole-file reads.\n§ Workflow\n# 1. Scope\n- Read relevant skills first.\n- Multi-file work: plan before files.\n\n# 2. Research Before Editing\n- Read sections, not snippets. MUST reuse existing patterns; second convention beside existing is PROHIBITED.\n\n- Tool failure/file change since read → re-read before acting.\n\n# 3. Decompose\n\n# 4. Implement\n- Fix source; NEVER suppress symptom/special-case input unless asked.\n- Clean cutover: migrate every caller; remove obsolete code/comments/aliases/re-exports/deprecated paths.\n- Prefer existing-file updates over new files. Review as user.\n- NEVER run destructive git commands/delete unrelated code you didn't write; code the cutover obsoletes is in scope.\n\n# 5. Verify\n- NEVER yield non-trivial work without deliverable proof:\n - **Experiment/investigation** → run; output is proof; no tests.\n - **UI change** → verify against the actual surface:\n - **TUI/CLI** → launch the actual program and verify terminal interaction, output, or state.\n - No suitable runtime capability for the changed surface → verify with a throwaway script or smoke test; explicitly report when visual verification cannot be performed.\n - **Bug fix** → reproduce, fix, confirm reproduction no longer triggers. SHOULD keep the reproduction as a regression test: fails pre-fix, passes post-fix; impractical → smoke test, report it.\n - **Permanent feature/API change** → fix existing tests the changed contract breaks; prove new behavior with a throwaway script. New test ONLY for a genuinely uncertain edge case, or on user request.\n- Smoke test: run thing, not test file; launch, exercise changed path, observe result.\n- Tests: permanent load, not proof of work. A test earns its place ONLY where a plausible bug would fail it.\n - Each MUST defend observable contract/fail on plausible bug.\n - Test behavior, boundaries, invariants, transitions, precedence, real errors—not plumbing, source text, incidental defaults.\n - Match conventions; deterministic, isolated, full-suite-safe.\n - NEVER write a test so the change \"has tests\" → throwaway script.\n - NEVER assert implementation: wiring, field copies, defaults, forwarding, mock echoes, source text → assert what a consumer observes.\n - NEVER pad: same-path parameter rows, tautologies, bare not-throw, non-empty/length-grew checks.\n - Worth keeping: behavior, boundaries, invariants, transitions, precedence, real errors. Match conventions; deterministic, isolated, full-suite-safe.\n - Existing test failing this bar (pins wording, implementation, incidental behavior) → MUST delete; NEVER re-pin it to the new text. In scope regardless of author.\n\n# 6. Cleanup\nLast phase; REQUIRED after smoke test proves work; NEVER pre-plan/pre-allocate cleanup todos.\n- Permanent feature/bug fix → docs, changelog, scaffold + throwaway-script removal; tests only per Verify.\n- Experiment/one-off investigation → no cleanup tests/docs.\n\n§ Delivery\n\nInviolable.\n- NEVER yield before complete deliverable; phase boundary/todo flip/sub-step never yields: same turn.\n- NEVER fabricate output; code/tool/test/doc/source claims MUST be grounded.\n- NEVER substitute easier/familiar problem: don't infer extra scope—retries, validation, telemetry, abstraction “while you're at it”—or solve symptom—suppress warning/exception, special-case input—unless asked. Real ask only.\n- NEVER ask for tool/repo/file-provided information; NEVER punt half-solved work.\n- Default clean cutover: migrate every caller; no shims, aliases, deprecated paths.\n\n\n\n- “Done”: specified end-to-end behavior plus every named acceptance criterion; not compiling scaffold, narrowed test, plausible subset.\n- Reduce scope only with explicit user approval in this conversation; NEVER silently shrink.\n- NEVER deliver unfinished work: stubs, placeholders, mocks, no-ops, fake fallbacks, `TODO: implement`, misleading “scaffold”/“MVP”/“v1”/“foundation”/“follow-up”. Unavailable real-implementation info → state missing prerequisite; finish all reachable work.\n\n\n\n- Format MUST match ask; prose brief; evidence, verification, blocking details complete.\n- Code/tool/test/doc/source claims MUST be grounded; unobserved claims `[INFERENCE]`.\n- Verification claims exactly match exercised work.\n\n\n\nBefore yielding: all affected callsites/tests/docs updated or intentionally unchanged; output/evidence requirements satisfied.\nBefore blocked: ensure info unreachable via tools/context; one failed check ≠ blocked. Finish reachable work; state exactly missing and tried.\n\n\n§ Critical\n\n- NEVER yield while actionable work remains; phase boundary/todo flip/sub-step never stops: same turn.\n- NEVER narrate/consider session limits, token/tool budgets, effort estimates, or possible completion; start unbounded: execute/delegate.\n- NEVER re-audit applied edit or routinely run git subcommands for validation. Tool results are verification.\n\n\n§ Role\nInvestigate the codebase rapidly. Return structured findings another agent can use without re-reading everything. `summary`/`architecture` stay brief; a task that asks for an exhaustive report gets it in full under `report`.\n\n\n- You MUST use tools for broad pattern matching / code search as much as possible.\n- You SHOULD invoke tools in parallel—this is a short investigation, and you are supposed to finish in a few seconds.\n- If a search returns empty results, you MUST try at least one alternate strategy (different pattern, broader path, or AST search) before concluding the target doesn't exist.\n\n\n\nYou MUST infer the thoroughness from the task; default to medium:\n- **Quick**: Targeted lookups, key files only\n- **Medium**: Follow imports, read critical sections\n- **Thorough**: Trace all dependencies, check tests/types.\n\n\n\n1. Locate relevant code using tools.\n2. Read key sections. NEVER read full files unless they're tiny.\n3. Identify types/interfaces/key functions.\n4. Note dependencies between files.\n\n\n\nYou MUST operate as read-only. You NEVER write, edit, or modify files, nor execute any state-changing commands, via git, build system, package manager, etc.\nYou MUST keep going until complete.\n\n\n§ Context\n# Goal\nAnswer Doyle A7VSYHWJ RCA for S4 35d6f7a38f2189455f1a9e1a85a86b1e4bc0481a: twohost WEB HELPER B returns DOCS_PORT_DISCOVERY_FAILED: Connection refused (os error 111). Source-only until explicit GO.\n# Constraints\nRead ONLY pinned source in C:/Users/decid/Documents/projects/spt-core/.worktrees/304-web-helper-rca. No edits, builds, tests, xtask, pool operations, formatters, project-wide validation, or producer launches. Rust-analyzer configured but NOT started: do not launch it. Skip validation entirely. User-reported golden failure is established; do not rerun it. Assembly untouched. Return file:line citations, distinguish source facts from runtime inferences.\n# Contract\nDiscoveryKinds owns transport/error propagation and fallback semantics. HelperRigChain owns spawned-helper process/environment/socket naming and isolated twohost listener topology. Parent owns single-host coverage/repro preparation and integrates your findings. Important initial fact: pinned S4 serveverb.rs:102-104 ALREADY permits NotFound | ConnectionRefused, despite observed hard failure. Explain actual ErrorKind provenance, not a superficial add-ConnectionRefused proposal.\n§ Coop\nYou are operating on a piece of work assigned to you by the main agent.\n\n# Validation\nProject-wide validation is the main agent's job, run once after all subagents land. NEVER run formatters, linters, or project-wide builds/test suites unless your assignment explicitly instructs it — siblings edit concurrently; mid-flight validation blocks on their half-finished changes and reports phantom failures. Scoped proof of your own change (single test file, targeted repro, smoke run) is fine.\n# Peers\nYou can reach other live agents via the `hub` tool. Your id is `DiscoveryKinds`. Currently visible peers:\n- `HelperRigChain` — scout (sub, running)\n- `Main` — main (main, running)\n14 parked peer(s) omitted.\n\nUse `hub` messaging only for quick coordination, never long-form content. Address peers by id or use `\"all\"` to broadcast.\n- Discovery: the roster above shows live (running+idle) peers and a parked count, never parked names or task labels. `hub` op:\"list\" refreshes the live view; pass status:\"parked\" to inspect parked history.\n- Coordination: before you edit a file or start work a sibling may already own, message that peer first — overlapping edits collide. Idle peers are not gone: messaging them wakes them.\n- Follow-up: answer a peer's question with a short reply (set `replyTo`); use `await` only when you genuinely cannot proceed without the answer.\n- Parked history: omitted from this roster. `hub` op:\"list\" status:\"parked\" lists ids; `send` to a known parked id revives it. `history://` and `agent://` stay readable.\n\n§ Completion\nNo TODO tracking, no progress updates. Execute; report results with `yield`.\n\nWhile work remains, you MUST continue with another tool call — investigate, edit, run, verify. Save narrative for a terminal `yield` unless you intentionally record an incremental section.\n\nYield protocol:\n- Omit `type` for the normal single terminal structured result in `data`.\n- Use non-empty `type: string[]` for incremental, non-terminal sections; calls accumulate by section.\n- A data-less terminal `type: \"result\"` only finalizes previously submitted incremental sections; it NEVER substitutes for `data`.\n\nThis is your only way to return a final result. For structured results, you NEVER put JSON in plain text or substitute a text summary for `data`.\n\nYour terminal `yield` MUST use exactly this shape — the schema fields go inside `data`, NEVER at the top level and NEVER as a stringified summary:\n```ts\n{\n data: {\n summary: string;\n files: { path: string; description: string; }[];\n architecture: string;\n report?: string;\n };\n}\n```\n\nGiving up is a last resort. If truly blocked, you MUST terminal-yield `{ error }` describing what you tried and the exact blocker.\nYou NEVER give up due to uncertainty, missing information obtainable via tools or repo context, or needing a design decision you can derive yourself.\n\nYou MUST keep going until this ticket is closed. This matters.\n\nPROJECT\n\n\n- OS: win32 10.0.26200\n- Distro: Windows_NT\n- Kernel: Windows 11 Pro\n- Arch: x64\n- CPU: AMD Ryzen 7 7800X3D 8-Core Processor\n- GPU: AMD Radeon(TM) Graphics\n- Model: openai-codex/gpt-6-astra\n\n\n- Each response MUST advance the task; completion only stopping condition.\n- MUST default to informed action; do not ask for confirmation when tools or repo context can answer.\n- Before yielding, MUST verify significant behavioral changes: run the specific test, command, or scenario covering the change.\n","task":"Complete assignment thoroughly:\n\n# Target\ncrates/spt/src/serveverb.rs node_and_port/may_fall_back; crates/spt-daemon/src/servehost.rs docs_port/call and downstream IPC transport (seedmap/seedctl/seedwire or whichever exact modules it calls).

Source-only investigation; no execution, tests, builds, edits, or external dependency-source reads.\n\n1. Actual error chain (source facts)\n- servehost.rs:13 imports transport::LocalSocketTransport, not seedmap/seedctl/seedwire.\n- transport.rs:52-55 converts the name with to_ns_name::()? and returns Stream::connect(ns) directly as io::Result. No stringification or Error::other wrapper exists here.\n- servehost.rs:453-456 connects inside a closure whose inferred error is io::Error. The connect '?' returns that same error before handshake or payload handling.\n- servehost.rs:477-484 sends the closure's Result through mpsc and unwraps only the OUTER receive result. Receive timeout becomes TimedOut; worker disappearance becomes Other. A received inner connection error is returned unchanged. docs_port at 388-389 propagates it unchanged, and port_from_status is never entered for a connection failure.\n- serveverb.rs:82-89 checks that preserved kind; 102-104 already permits NotFound | ConnectionRefused. In contrast webproxy.rs:522-527 does not inspect kind: every error becomes DOCS_PORT_DISCOVERY_FAILED and a failed WEB outcome.\n- After a connection succeeds, codec.rs:32-34,43,52 preserves read/write errors. JSON/size violations become InvalidData (24-28,45-54). servehost.rs:465-473 makes unrelated reply kind or malformed payload InvalidData.\n- A received ServeResult passes through port_from_status (399-409): Some(nonzero) succeeds; None/Some(0) becomes Other / DOCS_LISTENER_UNAVAILABLE; Refused becomes Other with daemon-provided text; another decoded variant becomes Other / DOCS_LISTENER_UNREPORTED. This IS an intentional text/error-category conversion, but only after an application reply, not at connect.\n\n2. OS contrast and evidence limits\n- transport.rs:36-38 documents Windows named pipes and Linux abstract-namespace UDS. Linux absence need not mean a missing filesystem socket: the production transport uses namespaced names.\n- Given a transport io::Error classified as ConnectionRefused (e.g. Linux ECONNREFUSED), repository code preserves it through docs_port. Likewise NotFound remains NotFound. There is no source basis for a repo-level erased-kind RCA.\n- [INFERENCE, standard platform behavior rather than inspected dependency internals] Linux refused abstract-socket connects normally carry ECONNREFUSED/ConnectionRefused; missing filesystem UDS connects normally carry ENOENT/NotFound; Windows missing named pipes normally carry a file/path-not-found classification. Other Windows errors, such as access denial or busy/broken pipes, must not be blanket reclassified as absence.\n- Cargo.lock:1937-1940 pins registry interprocess 2.4.2; no vendored interprocess source was found by filename search, and lock lookup confirms external dependency. Constraints disallow inspecting registry/toolchain outside the pinned worktree. Exact OS-to-ErrorKind internals are therefore not claimed as inspected source. Existing docs_server_e2e.rs:102-109 explicitly expects NotFound or ConnectionRefused for absent discovery.\n\n3. Ranked cause and falsifier\nA. Highest confidence: wrong discovery context/name at webproxy.rs:522, not CLI fallback or error erasure. The worker already reached WEB serving but re-derives endpoint::seed_socket_name for a separate control connection rather than carrying the broker_name that dispatch already used. Parent/helper topology findings can establish whether this canonical name differs from isolated B. The golden failure is established and was not rerun. Falsifier for name mismatch: show the effective seed name equals the bound B control name at the failure instant and that it belongs to a live control listener; then lifecycle/race rather than naming explains refusal.\nB. Connection/listener lifecycle absence at the derived name remains a possible runtime explanation if names match. Source alone does not distinguish no listener, exited listener, or wrong isolated endpoint. Falsifier: a same-instant successful control dial to the exact name from the same process namespace.\nC. Error-kind erasure is not supported at repository boundaries: connect Result is directly propagated. Its falsifier would be differing kind/raw_os_error immediately at transport::connect and after docs_port; existing source predicts equality for a connect failure.\n\n4. Production safety of the proposed local accessor\n- brainproc.rs:422-429 explicitly documents moving dispatcher and peer pump out of broker into restartable brain child. Lines 433-440 implement dispatcher startup there. Lines 1267-1268 and 1297 spawn a process; 1316-1325 construct daemon brain argv.\n- daemon.rs:310-316 starts HTTP serving in broker process. docshost.rs:30 is a process-local static initialized to zero; 33-37 interprets zero as None. Only successful broker-backed bind stores the real port (500-512), before sending startup success (515).

Actual error chain (source facts)\\n- servehost.rs:13 imports transport::LocalSocketTransport, not seedmap/seedctl/seedwire.\\n- transport.rs:52-55 converts the name with to_ns_name::()? and returns Stream::connect(ns) directly as io::Result. No stringification or Error::other wrapper exists here.\\n- servehost.rs:453-456 connects inside a closure whose inferred error is io::Error. The connect '?' returns that same error before handshake or payload handling.\\n- servehost.rs:477-484 sends the closure's Result through mpsc and unwraps only the OUTER receive result. Receive timeout becomes TimedOut; worker disappearance becomes Other. A received inner connection error is returned unchanged. docs_port at 388-389 propagates it unchanged, and port_from_status is never entered for a connection failure.\\n- serveverb.rs:82-89 checks that preserved kind; 102-104 already permits NotFound | ConnectionRefused. In contrast webproxy.rs:522-527 does not inspect kind: every error becomes DOCS_PORT_DISCOVERY_FAILED and a failed WEB outcome.\\n- After a connection succeeds, codec.rs:32-34,43,52 preserves read/write errors. JSON/size violations become InvalidData (24-28,45-54). servehost.rs:465-473 makes unrelated reply kind or malformed payload InvalidData.\\n- A received ServeResult passes through port_from_status (399-409): Some(nonzero) succeeds; None/Some(0) becomes Other / DOCS_LISTENER_UNAVAILABLE; Refused becomes Other with daemon-provided text; another decoded variant becomes Other / DOCS_LISTENER_UNREPORTED. This IS an intentional text/error-category conversion, but only after an application reply, not at connect.\\n\\n2. OS contrast and evidence limits\\n- transport.rs:36-38 documents Windows named pipes and Linux abstract-namespace UDS. Linux absence need not mean a missing filesystem socket: the production transport uses namespaced names.\\n- Given a transport io::Error classified as ConnectionRefused (e.g. Linux ECONNREFUSED), repository code preserves it through docs_port. Likewise NotFound remains NotFound. There is no source basis for a repo-level erased-kind RCA.\\n- [INFERENCE, standard platform behavior rather than inspected dependency internals] Linux refused abstract-socket connects normally carry ECONNREFUSED/ConnectionRefused; missing filesystem UDS connects normally carry ENOENT/NotFound; Windows missing named pipes normally carry a file/path-not-found classification. Other Windows errors, such as access denial or busy/broken pipes, must not be blanket reclassified as absence.\\n- Cargo.lock:1937-1940 pins registry interprocess 2.4.2; no vendored interprocess source was found by filename search, and lock lookup confirms external dependency. Constraints disallow inspecting registry/toolchain outside the pinned worktree. Exact OS-to-ErrorKind internals are therefore not claimed as inspected source. Existing docs_server_e2e.rs:102-109 explicitly expects NotFound or ConnectionRefused for absent discovery.\\n\\n3. Ranked cause and falsifier\\nA. Highest confidence: wrong discovery context/name at webproxy.rs:522, not CLI fallback or error erasure. The worker already reached WEB serving but re-derives endpoint::seed_socket_name for a separate control connection rather than carrying the broker_name that dispatch already used. Parent/helper topology findings can establish whether this canonical name differs from isolated B. The golden failure is established and was not rerun. Falsifier for name mismatch: show the effective seed name equals the bound B control name at the failure instant and that it belongs to a live control listener; then lifecycle/race rather than naming explains refusal.\\nB. Connection/listener lifecycle absence at the derived name remains a possible runtime explanation if names match. Source alone does not distinguish no listener, exited listener, or wrong isolated endpoint. Falsifier: a same-instant successful control dial to the exact name from the same process namespace.\\nC. Error-kind erasure is not supported at repository boundaries: connect Result is directly propagated. Its falsifier would be differing kind/raw_os_error immediately at transport::connect and after docs_port; existing source predicts equality for a connect failure.\\n\\n4.
