+# Constraint Budget Tracking
+
+When the user or system imposes constraints (question limits, revision limits, time budgets), maintain a visible counter in your responses and in the artifact.
+
+## Format
+
+```
+📊 Clarifying questions used: 2 / 3
+```
+
+## Rules
+
+- Update the counter each time the constraint is consumed
+- When a constraint is exhausted, state it: `📊 Question budget exhausted (3/3). Proceeding with current information.`
+- If no constraints are active, do not display counters
+- Include the final constraint status in multi-agent artifacts
+
+## Example Session
+
+```
+Coordinator: Spawning agents to analyze requirements...
+📊 Clarifying questions used: 0 / 3
+
+Agent asks clarification: "Should we support OAuth?"
+Coordinator: Checking with user...
+📊 Clarifying questions used: 1 / 3
+
+Agent asks clarification: "What's the rate limit?"
+Coordinator: Checking with user...
+📊 Clarifying questions used: 2 / 3
+
+Agent asks clarification: "Do we need RBAC?"
+Coordinator: Checking with user...
+📊 Clarifying questions used: 3 / 3
+
+Agent asks clarification: "Should we cache responses?"
+Coordinator: 📊 Question budget exhausted (3/3). Proceeding without clarification.

+# Copilot Coding Agent — Squad Instructions
+
+You are working on a project that uses **Squad**, an AI team framework. When picking up issues autonomously, follow these guidelines.
+
+## Team Context
+
+Before starting work on any issue:
+
+1. Read `.squad/team.md` for the team roster, member roles, and your capability profile.
+2. Read `.squad/routing.md` for work routing rules.
+3. If the issue has a `squad:{member}` label, read that member's charter at `.squad/agents/{member}/charter.md` to understand their domain expertise and coding style — work in their voice.
+
+## Capability Self-Check
+
+Before starting work, check your capability profile in `.squad/team.md` under the **Coding Agent → Capabilities** section.
+
+- **🟢 Good fit** — proceed autonomously.
+- **🟡 Needs review** — proceed, but note in the PR description that a squad member should review.
+- **🔴 Not suitable** — do NOT start work. Instead, comment on the issue:
+  ```
+  🤖 This issue doesn't match my capability profile (reason: {why}). Suggesting reassignment to a squad member.
+  ```
+
+## Branch Naming
+
+Use the squad branch convention:
+```
+squad/{issue-number}-{kebab-case-slug}
+```
+Example: `squad/42-fix-login-validation`
+
+## PR Guidelines
+
+When opening a PR:
+- Reference the issue: `Closes #{issue-number}`
+- If the issue had a `squad:{member}` label, mention the member: `Working as {member} ({role})`
+- If this is a 🟡 needs-review task, add to the PR description: `⚠️ This task was flagged as "needs review" — please have a squad member review before merging.`
+- Follow any project conventions in `.squad/decisions.md`
+
+## Decisions
+
+If you make a decision that affects other team members, write it to:
+```
+.squad/decisions/inbox/copilot-{brief-slug}.md
+```
+The Scribe will merge it into the shared decisions file.

+# MCP Integration — Configuration and Samples
+
+MCP (Model Context Protocol) servers extend Squad with tools for external services — Trello, Aspire dashboards, Azure, Notion, and more. The user configures MCP servers in their environment; Squad discovers and uses them.
+
+> **Full patterns:** Read `.squad/skills/mcp-tool-discovery/SKILL.md` for discovery patterns, domain-specific usage, and graceful degradation.
+
+## Config File Locations
+
+Users configure MCP servers at these locations (checked in priority order):
+1. **Repository-level:** `.copilot/mcp-config.json` (team-shared, committed to repo)
+2. **Workspace-level:** `.vscode/mcp.json` (VS Code workspaces)
+3. **User-level:** `~/.copilot/mcp-config.json` (personal)
+4. **CLI override:** `--additional-mcp-config` flag (session-specific)
+
+## Sample Config — Trello
+
+```json
+{
+  "mcpServers": {
+    "trello": {
+      "command": "npx",
+      "args": ["-y", "@trello/mcp-server"],
+      "env": {
+        "TRELLO_API_KEY": "${TRELLO_API_KEY}",
+        "TRELLO_TOKEN": "${TRELLO_TOKEN}"
+      }
+    }
+  }
+}
+```
+
+## Sample Config — GitHub
+
+```json
+{
+  "mcpServers": {
+    "github": {
+      "command": "npx",
+      "args": ["-y", "@modelcontextprotocol/server-github"],
+      "env": {
+        "GITHUB_TOKEN": "${GITHUB_TOKEN}"
+      }
+    }
+  }
+}
+```
+
+## Sample Config — Azure
+
+```json
+{
+  "mcpServers": {
+    "azure": {
+      "command": "npx",
+      "args": ["-y", "@azure/mcp-server"],
+      "env": {
+        "AZURE_SUBSCRIPTION_ID": "${AZURE_SUBSCRIPTION_ID}",
+        "AZURE_CLIENT_ID": "${AZURE_CLIENT_ID}",
+        "AZURE_CLIENT_SECRET": "${AZURE_CLIENT_SECRET}",
+        "AZURE_TENANT_ID": "${AZURE_TENANT_ID}"
+      }
+    }
+  }
+}
+```
+
+## Sample Config — Aspire
+
+```json
+{
+  "mcpServers": {
+    "aspire": {
+      "command": "npx",
+      "args": ["-y", "@aspire/mcp-server"],
+      "env": {
+        "ASPIRE_DASHBOARD_URL": "${ASPIRE_DASHBOARD_URL}"
+      }
+    }
+  }
+}
+```
+
+## Authentication Notes
+
+- **GitHub MCP requires a separate token** from the `gh` CLI auth. Generate at https://github.com/settings/tokens
+- **Trello requires API key + token** from https://trello.com/power-ups/admin
+- **Azure requires service principal credentials** — see Azure docs for setup
+- **Aspire uses the dashboard URL** — typically `http://localhost:18888` during local dev
+
+Auth is a real blocker for some MCP servers. Users need separate tokens for GitHub MCP, Azure MCP, Trello MCP, etc. This is a documentation problem, not a code problem.

+# Multi-Agent Artifact Format
+
+When multiple agents contribute to a final artifact (document, analysis, design), use this format. The assembled result must include:
+
+- Termination condition
+- Constraint budgets (if active)
+- Reviewer verdicts (if any)
+- Raw agent outputs appendix
+
+## Assembly Structure
+
+The assembled result goes at the top. Below it, include:
+
+```
+## APPENDIX: RAW AGENT OUTPUTS
+
+### {Name} ({Role}) — Raw Output
+{Paste agent's verbatim response here, unedited}
+
+### {Name} ({Role}) — Raw Output
+{Paste agent's verbatim response here, unedited}
+```
+
+## Appendix Rules
+
+This appendix is for diagnostic integrity. Do not edit, summarize, or polish the raw outputs. The Coordinator may not rewrite raw agent outputs; it may only paste them verbatim and assemble the final artifact above.
+
+See `.squad/templates/run-output.md` for the complete output format template.

+# Plugin Marketplace
+
+Plugins are curated agent templates, skills, instructions, and prompts shared by the community via GitHub repositories (e.g., `github/awesome-copilot`, `anthropics/skills`). They provide ready-made expertise for common domains — cloud platforms, frameworks, testing strategies, etc.
+
+## Marketplace State
+
+Registered marketplace sources are stored in `.squad/plugins/marketplaces.json`:
+
+```json
+{
+  "marketplaces": [
+    {
+      "name": "awesome-copilot",
+      "source": "github/awesome-copilot",
+      "added_at": "2026-02-14T00:00:00Z"
+    }
+  ]
+}
+```
+
+## CLI Commands
+
+Users manage marketplaces via the CLI:
+- `squad plugin marketplace add {owner/repo}` — Register a GitHub repo as a marketplace source
+- `squad plugin marketplace remove {name}` — Remove a registered marketplace
+- `squad plugin marketplace list` — List registered marketplaces
+- `squad plugin marketplace browse {name}` — List available plugins in a marketplace
+
+## When to Browse
+
+During the **Adding Team Members** flow, AFTER allocating a name but BEFORE generating the charter:
+
+1. Read `.squad/plugins/marketplaces.json`. If the file doesn't exist or `marketplaces` is empty, skip silently.
+2. For each registered marketplace, search for plugins whose name or description matches the new member's role or domain keywords.
+3. Present matching plugins to the user: *"Found '{plugin-name}' in {marketplace} marketplace — want me to install it as a skill for {CastName}?"*
+4. If the user accepts, install the plugin (see below). If they decline or skip, proceed without it.
+
+## How to Install a Plugin
+
+1. Read the plugin content from the marketplace repository (the plugin's `SKILL.md` or equivalent).
+2. Copy it into the agent's skills directory: `.squad/skills/{plugin-name}/SKILL.md`
+3. If the plugin includes charter-level instructions (role boundaries, tool preferences), merge those into the agent's `charter.md`.
+4. Log the installation in the agent's `history.md`: *"📦 Plugin '{plugin-name}' installed from {marketplace}."*
+
+## Graceful Degradation
+
+- **No marketplaces configured:** Skip the marketplace check entirely. No warning, no prompt.
+- **Marketplace unreachable:** Warn the user (*"⚠ Couldn't reach {marketplace} — continuing without it"*) and proceed with team member creation normally.
+- **No matching plugins:** Inform the user (*"No matching plugins found in configured marketplaces"*) and proceed.
