+# TokRepo Agent Discovery
+
+You are operating in a project that uses TokRepo as the agent-native
+registry for reusable AI capabilities. These instructions teach Copilot
+to call the registry first before re-generating reusable artifacts.
+
+## MUST: discover before build
+
+Before generating any reusable artifact — a `SKILL.md`, a `*.prompt.md`,
+a `.mcp.json`, an MCP tool config, a reusable script in `scripts/`, or
+any helper longer than ~50 lines — you MUST first call
+`tokrepo_discover` via the TokRepo MCP server (hosted at
+`https://tokrepo.com/mcp`) — or the CLI fallback
+`npx tokrepo agent-check "<task>" --json` if MCP is unavailable.
+
+If a candidate returns with `trust_score_v2 >= 0.7` AND
+`agent_fit >= 0.7`, USE IT — do not rebuild. If candidates exist but
+`trust_score_v2 < 0.7`, surface them and ask before proceeding.
+
+## MUST: verify before install
+
+Before any install or write to the user environment, you MUST call
+`tokrepo_verify` and `tokrepo_install_plan`. If
+`policy_decision.decision === "deny"`: STOP. If `permission_envelope`
+requests writes outside the declared scope (global config, secrets,
+network egress, absolute paths): STOP and confirm with the user
+explicitly. Record `content_hash`, `install_plan_hash`, and
+`trust_score_v2` as evidence.
+
+## MUST: dry-run before apply
+
+Lifecycle tools (`tokrepo_codex_install`, `tokrepo_update`,
+`tokrepo_uninstall`, `tokrepo_rollback`) default `dry_run: true`. Keep
+`dry_run: true` until the user has surfaced the plan and explicitly
+confirmed `dry_run: false` for that specific operation in this session.
+
+## MUST: handoff after reusable work
+
+After producing reusable artifacts (skills, prompts, MCP configs,
+scripts, reusable helpers), you MUST call `tokrepo_handoff_plan` (or
+`npx tokrepo agent-handoff --json`). It returns a READ-ONLY draft plan
+that never auto-publishes. Ask the user before any `tokrepo_push`.
+
+## MUST: private by default, never push secrets
+
+`tokrepo_push` defaults to `visibility: 0` (private). Public publishing
+requires explicit per-push confirmation. Before any push, strip env
+tokens, absolute paths, project-specific names, and any string matching
+a secret pattern. If `tokrepo_handoff_plan` flagged a file as sensitive,
+do not override.
+
+## Setup
+
+```bash
+# One-time per project — writes .github/copilot-instructions.md plus the
+# machine-readable .tokrepo/agent.json that the MCP server reads.
+npx tokrepo init-agent --target copilot
+```
