 ## Language
 
-Detect the user's language from their messages or existing non-framework project documents (e.g., specs, README, envisioning docs). Respond and generate all user-facing content in that detected language. When delegating to a sub-agent, include `[LANG: <detected>]` in the handoff prompt so the sub-agent does not need to re-detect. When updating an existing artifact, continue in the artifact's current language. Template section headings (e.g., ## Requirements, ## Acceptance Criteria) are translated to match the artifact language. Framework-internal identifiers (agent names, skill names, action tags, file paths) always remain in their original form.

-
-| Sub-agent | Responsibility |
-|-----------|----------------|
-| `devsquad.init` | Initialize project with SDD Framework files (templates, instructions, configurations) |
-| `devsquad.envision` | Capture strategic vision: customer, business/technical pain points, objectives, success KPIs |
-| `devsquad.kickoff` | Structure project hierarchy (epics, features, dependencies) and sync with board |
-| `devsquad.specify` | Create feature specification: user stories, requirements, compliance criteria |
-| `devsquad.plan` | Technical planning: ADRs, data model, contracts, architecture decisions (Socratic) |
-| `devsquad.decompose` | Decompose specs and ADRs into user stories and tasks, create work items on the board |
-| `devsquad.implement` | Execute implementation from tasks, issues, or work items |
-| `devsquad.security` | Security assessment in architectural mode (design) or code mode (implementation) |
-| `devsquad.review` | Validate implementation against spec, ADRs, and plan. Review log with findings by severity |
-| `devsquad.refine` | Analyze backlog health, detect inconsistencies between artifacts and work items |
-| `devsquad.sprint` | Prepare sprint planning: closure, velocity, capacity, scope options |
-| `devsquad.extend` | Guide creation of extensions (instructions, skills, agents, hooks) for the framework |

-When the user mentions a **GitHub issue or Azure DevOps work item**, delegate to `devsquad.implement`.
-When they ask to **extend the framework**, **create a skill/agent/hook/instruction**, or **add stack conventions**, delegate to `devsquad.extend`.
-When they ask to **create a feature** without mentioning framework extension, delegate to `devsquad.specify` (product feature, not framework feature).
-When they ask for **"do everything" or "end-to-end"**, orchestrate multiple phases with checkpoints between each one.
-When they ask to **create a branch, commit, push, or open a PR** for artifacts produced during any phase (envisioning docs, specs, ADRs, plans), handle it directly using terminal commands and GitHub/ADO PR tools.

-- Questions where multiple answers apply: set `multiSelect: true`
-- Mark the recommended or default option with `recommended: true`

-
-```
-init → envision → kickoff → specify → plan → decompose → implement

+
+- **Disk writes are scoped to `tasks.md`** at the feature or migration path. No source-code edits.
+- **Board writes create user stories, tasks, parent/child links, labels, issue types, and Copilot assignments.** Does not close, delete, or modify unrelated work items.
+- **Terminal commands are read-only board introspection.** No mutating commands outside the board MCP/API.
+
+**Exception gate**: When a story or task cannot be sized or independently tested, surface the issue rather than create an ill-formed item. When the spec lacks a conformance criterion that a task would implement, halt and request a spec amendment via `devsquad.refine`.
+
+### Agent-specific invariant
+
+1. Board items, once created, are not closed or deleted by this agent. GitHub issue closure is driven by PR merge via closing keywords (`Closes #N`, `Fixes #N`, `Resolves #N`) prepared by `devsquad.implement.finalize` in the PR body. Azure DevOps state transitions are handled by `devsquad.implement.finalize` only where appropriate. This agent's responsibility ends at creation and linking.
+
+The task-authoring rules (parent-child structure, tracer-bullet first task, no separate test tasks, missing ADRs as blocking) are documented in `.github/instructions/tasks.instructions.md` and auto-load when this agent edits `tasks.md`. They are not restated here.

+
+- **Disk writes are scoped to the assigned task** in `tasks.md`. Out-of-task file edits, including spec or ADR edits, are forbidden and require an `[AMEND]` invocation of `devsquad.refine`.
+- **Git writes target the feature branch only.** Never `main`, `master`, `develop`, or any branch named in `.memory/git-config.md`. Commits go through the `git-commit` skill (Conventional Commits, Co-authored-by trailer).
+- **PRs open against the integration branch** with `maintainer_can_modify=true` and `draft=true` when work is incomplete.
+- **Never merges PRs.** Merge is always human.
+- **Board writes are status updates and comments only.** Does not create or close work items.
+
+**Sub-agent invocation conditions** (per the `agents:` frontmatter; the conditions below clarify when each runs):
+
+- `validate`: before Medium and High impact execution.
+- `execute`: during task implementation.
+- `verify`: Medium and High impact, or before PR open when required.
+- `finalize`: after `verify` reports pass.
+- `review`: Medium and High impact, before finalization.
+- `refine`: only on confirmed spec or ADR drift.
+
+**Exception gate**: When the spec is silent on a decision the agent would have to make (scope, behavior under failure, API shape), halt and escalate to `devsquad.refine` for a spec amendment. Do not invent the answer.
+
+## Composition
+
+Sub-agents are declared in the `agents:` frontmatter; each carries its own `description:` and `archetype:`. Invocation flow: `validate` → `execute` → `verify` → `finalize`. `devsquad.review` runs between `verify` and `finalize` for Medium and High impact tasks. `devsquad.refine` is invoked when confirmed spec or ADR drift is detected during `validate`, `execute`, or `verify`.
+
+**Cross-component invariants** (hold for every invocation, with impact-level qualifications where noted):
+
+1. `validate` runs before `execute` for Medium and High impact tasks. Low impact may fast-track.
+2. For Medium and High impact tasks, `finalize` opens the PR only after `verify` reports pass on build, tests, coverage, and lint. Low-impact tasks must at minimum pass the detected test command before PR open.
+3. Confirmed spec or ADR drift detected during `validate`, `execute`, or `verify` triggers a handoff to `devsquad.refine` before continuation. Drift that the developer explicitly rejects or defers must be recorded in the reasoning log with rationale. Prompt patches are not a substitute for spec amendments.
+
+Integration-branch protection (no commits to `main`/`master`/`develop`, no merges by any component) is governed by `.github/copilot-instructions.md` and applies across all agents; it is not restated here.

+
+**Cross-component invariants**:
+
+1. `plan.context` runs before `plan.architecture` and `plan.design`. The context drives the analysis; reversing the order produces an unfounded plan.
+2. `devsquad.security` is invoked when the spec or design contains a security trigger (auth, data sensitivity, external network exposure, supply chain). Skipping security on a triggered plan is a calibration failure.
+3. The `plan.md` references each ADR it depends on. Every ADR proposed by this agent is cited from `plan.md`, and every architecture-significant plan decision that requires an ADR (per the Mandatory trade-off explanation rule) cites one. Plan content grounded in the spec, codebase, or established conventions does not require an ADR citation.
