+# A2A Card: SIN-GitHub-Issues
+
+## Identitaet
+
+- `A2A Bezeichnung`: `SIN-GitHub-Issues`
+- `Name`: `SIN-GitHub-Issues`
+- `Beschreibung (Zweck)`: GitHub issue execution agent for confirmed bugs, repo issue lifecycle, branch-based fixes, and verification handoff.
+- `Verwendung`: Use after enterprise-deep-debug confirms a bug to search/create/update GitHub issues, open a repo branch, execute the fix workflow, commit, push, and report verification status back to the orchestrating CLI agent.
+- `CIMD`: `https://delqhi-sin-github-issues.hf.space`
+
+## Team & Infrastruktur
+
+- `A2A Team`: `Team - Coding`
+- `Team-Manager A2A`: `SIN-Coding-CEO`
+- `VM / Server`: `Target: Hugging Face Space free CPU VM`
+- `Lokales Verzeichnis`: `/Users/jeremy/dev/SIN-Solver/a2a/team-coding/A2A-SIN-GitHub-Issues`
+- `Hugging Face Space URL`: `https://huggingface.co/spaces/delqhi/sin-github-issues`
+- `Landingpage URL`: `https://delqhi-sin-github-issues.hf.space`
+- `Cloudflare Tunnel`: `sin-github-issues`
+- `Workforce Ziel-Index`: `https://a2a.delqhi.com/`
+- `Google Docs Tab`: `https://docs.google.com/document/d/1RtoHn4I0GntuEEOHHkqoh_dMuGzgMwQz7_8oxAOpQbw/edit?tab=t.tuv2t449f8ze`
+
+## Auth- und Secrets-Modell
+
+- `Primäre lokale GitHub-Lane`: `gh` CLI auf dem Operator-Host
+- `Ziel-Lane`: GitHub Session-Grants via `SIN-Authenticator` (aktuell blockiert)
+- `Browser-Profil`: `zukunftsorientierte.energie@gmail.com` / Chrome Profil `Default`
+- `HF Session Backup`: `HF_DATASET_REPO` + `HF_TOKEN`
+- `SIN-Supabase`: `SIN_SUPABASE_URL` + `SIN_SUPABASE_SERVICE_ROLE_KEY`
+- `Aktueller Blocker`: GitHub-Provider in `SIN-Authenticator` noch nicht exponiert, SIN-Supabase/HF Runtime noch nicht live gekoppelt
+
+## MCP Server
+
+- `MCP Server`: `sin-github-issues`
+- `Transport`: `stdio`
+- `Config`: `./mcp-config.json`
+
+## CDP (Chrome DevTools Protocol)
+
+- `Lokale Browser-Lane`: Chrome Profil `Default` fuer `zukunftsorientierte.energie@gmail.com`
+- `Verwendung`: nur fuer browserpflichtige GitHub-Schritte; normale Issue-/Git-Lane bleibt CLI-first
+
+## Tools

+# SIN-GitHub-Issues
+
+- Team: Team - Coding
+- Team Manager: SIN-Coding-CEO
+- Slug: sin-github-issues
+- Repo: https://github.com/Delqhi/sin-github-issues
+- Docs Tab: https://docs.google.com/document/d/1RtoHn4I0GntuEEOHHkqoh_dMuGzgMwQz7_8oxAOpQbw/edit?tab=t.tuv2t449f8ze
+
+Arbeitsregel:
+- Jede neue Action muss in `runtime.ts`, `mcp-server.ts`, `a2a-http.ts`, `metadata.ts` und `A2A-CARD.md` synchronisiert werden.
+- Kein neuer Agent gilt als fertig, wenn Card, Dashboard-Registry und Docs-Tab nicht gemeinsam aktualisiert wurden.
+- Jeder neue Agent muss auch `agent.json`, `AGENTS.md`, `mcp-config.json`, `clients/opencode-mcp.json`, `clients/codex-config.toml`, `.well-known/agent-card.json`, `.well-known/agent.json`, `.well-known/oauth-client.json` und ggf. einen `bin/`-Wrapper sauber besitzen.
+- Google Docs Child-Tabs immer rekursiv ueber `includeTabsContent=true` + `childTabs` aufloesen. Nie nur Top-Level-Tabs pruefen.
+- Wenn der Team-Haupt-Tab eine finalisierte A2A-Team-Tabelle hat und dieselbe Tabelle im `Silicon Workforce`-Tab gespiegelt wird, muessen beide Tabellen synchron gehalten werden. Das finale Tabellen-Schema darf nicht stillschweigend geaendert werden.
+- Uebersichtstabellen im `Silicon Workforce`-Tab verwenden final das Schema: linke Typ-Spalte + `Bezeichnung | Zweck | URL`.
+- Team-Haupttabellen und deren Spiegel im `Silicon Workforce`-Tab verwenden final das Schema: linke Typ-Spalte + `Bezeichnung | Zweck | MCP's | Commands | Endpoints | Server (VM) | CLI's | URL`.
+- Jeder Team-Haupt-Tab enthaelt nur seine synchronisierte Team-Tabelle; dieselbe Tabelle wird im `Silicon Workforce`-Tab mit sichtbarer Trennlinie zwischen Team-Sektionen gespiegelt.
+- Pflichtfelder fuer neue A2A-Agenten:
+  - Identitaet, Team, Team-Manager, Zweck, Verwendung
+  - Auth-/Secrets-Modell
+  - MCP-Tools und A2A-Actions/Skills
+  - Commands, Endpoints, Capabilities, Input/Output-Modi
+  - Task-Lifecycle, Observability/Audit, Release/Rollback
+  - Owner/Oncall, Dependencies, Deploy-Ziel
+- Pflichtintegration:
+  - repo `.opencode/opencode.json`
+  - globale OpenCode-MCP-Integration falls benoetigt
+  - Dashboard-/Workforce-Registry + Detailseite `dashboard-enterprise/app/agents/<slug>/page.tsx`
+  - `a2a.delqhi.com` Landing/Card
+  - Google Docs Child-Tab + Team-Tabellen
+  - `cloudflared/config.example.yml`, wenn der Agent eine oeffentliche Runtime / einen Tunnel bekommen soll
+  - echte Runtime-Provisionierung + echter Publish/Deploy-Schritt, sobald oeffentliche URLs/HF/tunnel eingetragen werden
+- Falls der benoetigte Google-Docs-Child-Tab noch nicht existiert, muss er zuerst manuell im Google-Docs-UI erstellt werden. Die Docs-API kann bestehende Tabs pflegen, aber keine neuen Child-Tabs erzeugen.
+- Pflichtvalidierung vor Done:
+  - Build/Typecheck
+  - A2A health/card/rpc
+  - MCP smoke
+  - relevante Repo-Gates
+  - OpenCode-Integration
+  - Google-Docs-Sync
+  - `npm --prefix <agent-root> run build`
+  - `node <agent-root>/dist/src/cli.js print-card`
+  - `node <agent-root>/dist/src/cli.js run-action '{"action":"agent.help"}'`
+  - `node <agent-root>/dist/src/cli.js run-action '{"action":"<namespace>.health"}'` anhand der echten Skill-ID aus der Card
+  - `serve-mcp` bleibt mit offenem stdin erreichbar
+  - `npm run test:a2a:fleet`
+  - `npm run test:a2a:live -- --agent <slug>`
+  - Landing / `publicPageUrl` liefert `200`
+  - Runtime-Host ist real provisioniert
+  - `/.well-known/agent-card.json` liefert `200`
+  - `/a2a/v1` liefert nicht `404`
+- Ein Agent darf erst auf `ready` / `live` gesetzt werden, wenn diese Reachability-Pruefungen bestanden sind und Registry/Card/Docs denselben auditieren Stand zeigen.
+- Beim Fuellen der Team-Tabellen muessen alle freigegebenen Spalten gepflegt werden. Platzhalter wie `pending formal MCP entry` oder `pending dedicated child-tab` sind nur zulaessig, wenn die jeweilige Surface real noch nicht provisioniert ist.

+
+Current blockers:
+- GitHub provider/session-grant support is not yet exposed by `SIN-Authenticator`
+- SIN-Supabase env coupling is not yet live
+- HF Space/runtime deployment is not yet live
+
+## Runtime Shape
+
+- A2A JSON-RPC runtime
+- MCP stdio runtime
+- CLI wrapper for local and automated use
+- publish-ready Docker/Hugging Face Space layout
+- keep-alive ping + HF dataset session backup hooks
+- best-effort `sin-supabase` audit persistence for workflow events
+
+## A2A Surface
+
+- Card: `GET /.well-known/agent-card.json`
+- Alias: `GET /.well-known/agent.json`
+- Health: `GET /health`
+- RPC: `POST /a2a/v1`
+
+## MCP Surface
+
+- Transport: `stdio`
+- Config: `./mcp-config.json`
+- OpenCode client: `./clients/opencode-mcp.json`
+- Codex client: `./clients/codex-config.toml`
+
+## Local Commands
+
+```bash
+sin-github-issues serve-a2a
+sin-github-issues serve-mcp
+sin-github-issues print-card
+sin-github-issues run-action '{"action":"agent.help"}'
+sin-github-issues run-action '{"action":"sin.github.issues.health"}'

+sin-github-issues run-action '{"action":"sin.github.issues.issue.ensure","repo":"owner/name","title":"Bug title","body":"..."}'
+sin-github-issues run-action '{"action":"sin.github.issues.repo.branch.start","repoPath":"/abs/repo","branchName":"fix/example"}'
+
+## Current Action Surface
+
+- issue ensure / comment / close
+- repo status / branch start / commit / push
+- finalize-fix comment/closure handoff
+- auth status + onboarding state
+```
+
+## Publication Notes
+
+- This package is Docker/Hugging Face Space ready via the repository `Dockerfile`.
+- The standalone GitHub repo should contain the same contents as this directory root.
+- Remote publication is only complete after landing, agent card, and A2A endpoint reachability are verified with the live audit.
