+# Phase 1: Load & Bind
+
+## Objective
+
+Locate and load the workflow template, collect any missing context variables from the user, bind all `{variable}` references.
+
+## Workflow
+
+### Step 1.1 — Resolve Template Path
+
+Parse `$ARGUMENTS` for template identifier:
+
+**Path resolution order**:
+1. Absolute path: use as-is
+2. Relative path (starts with `.`): resolve from cwd
+3. Slug only (e.g. `feature-tdd-review`): look up in `.workflow/templates/index.json` → get path
+4. Partial slug match: scan index for closest match → confirm with user
+
+If not found:
+- Show available templates from index
+- AskUserQuestion: "Which template to run?"
+
+### Step 1.2 — Parse --context Arguments
+
+Extract `--context key=value` pairs from `$ARGUMENTS`.
+
+Examples:
+```
+--context goal="Implement user auth" --context scope="src/auth"
+--context goal='Fix login bug' scope=src/auth
+```
+
+Build `bound_context = { goal: "...", scope: "..." }`.
+
+### Step 1.3 — Load Template
+
+Read template JSON from resolved path.
+
+Validate:
+- `template_id`, `nodes`, `edges`, `context_schema` all present
+- `nodes` array non-empty
+
+### Step 1.4 — Collect Missing Required Variables
+
+For each variable in `context_schema` where `required: true`:
+- If not in `bound_context`: collect via AskUserQuestion
+- If has `default` value: use default if not provided
+
+```
+AskUserQuestion({
+  questions: [{
+    question: "Provide values for required workflow inputs:",
+    header: "Workflow: <template.name>",
+    // one question per missing required variable
+  }]
+})
+```
+
+For optional variables not provided: use `default` value or leave as empty string.
+
+### Step 1.5 — Bind Variables
+
+Apply substitution throughout all `args_template` strings:
+- Replace `{variable_name}` with `bound_context[variable_name]`
+- Leave `{N-001.session_id}` and `{prev_*}` references unresolved — these are runtime-resolved in Phase 3
+
+Write bound context to memory for Phase 3 use.
+
+### Step 1.6 — Dry Run Output (if --dry-run)
+
+Print execution plan and exit:
+```
+Workflow: <template.name>
+Context:
+  goal = "<value>"
+  scope = "<value>"
+
+Execution Plan:
+  [1] N-001  [skill]       workflow-lite-plan   "<goal>"
+  [2] CP-01  [checkpoint]  After Plan           auto-continue
+  [3] N-002  [skill]       workflow-execute     --resume-session {N-001.session_id}
+  [4] CP-02  [checkpoint]  Before Tests         pause-for-user
+  [5] N-003  [skill]       workflow-test-fix    --session {N-002.session_id}
+
+To execute: Skill(skill="wf-player", args="<slug> --context goal='...'")
+```
+
+## Success Criteria
+
+- Template loaded and validated
+- All required context variables bound
+- bound_context{} available for Phase 2
