Planner Hard Skill

Hard-mode wrapper that delegates plan creation to planner-hard-agent subagent. Extends skill-planner with H8 plan requirements passed in delegation context.

Relationship to base skill: Structurally identical to skill-planner except it dispatches to planner-hard-agent and passes H8 plan requirements. Maintenance note: changes to skill-planner postflight should be mirrored here.

Execution Flow

Stage 1: Input Validation

task_data=$(jq -r --argjson num "$task_number" \
  '.active_projects[] | select(.project_number == $num)' \
  specs/state.json)

if [ -z "$task_data" ]; then
  return error "Task $task_number not found"
fi

task_type=$(echo "$task_data" | jq -r '.task_type // "general"')
status=$(echo "$task_data" | jq -r '.status')
project_name=$(echo "$task_data" | jq -r '.project_name')
description=$(echo "$task_data" | jq -r '.description // ""')

if [ "$status" = "completed" ] || [ "$status" = "abandoned" ] || [ "$status" = "expanded" ]; then
  return error "Task is in terminal state [$status]"
fi

---

Stage 1.5: Hard-Mode Cost Note

session_flag_file="/tmp/.hard-mode-notified-${SESSION_ID:-$$}"
if [ ! -f "$session_flag_file" ]; then
  echo "[hard-mode] Hard mode active. Cost: ~3-5x standard. Use --hard for deflection-prone or formally complex tasks." >&2
  touch "$session_flag_file"
fi

---

Stage 2 + Stage 3: Preflight Status Update and Postflight Marker

Source skill-base.sh once, then follow @.claude/context/patterns/skill-preflight-flow.md in full for Stage 2 (preflight status update) and Stage 3 (marker creation):

source .claude/scripts/skill-base.sh
padded_num=$(printf "%03d" "$task_number")
skill_name="skill-planner-hard"
operation="plan"

Marker unification note: this skill's marker previously dropped created and stop_hook_active (Shape C) — a drift, not a hard-mode design decision. Routing through skill_create_postflight_marker restores both fields as part of this conversion, matching every other importer's Shape A schema.

---

Stage 3a: Read Artifact Number

artifact_number=$(jq -r --argjson num "$task_number" \
  '.active_projects[] | select(.project_number == $num) | .next_artifact_number // 1' \
  specs/state.json)

if [ "$artifact_number" = "null" ] || [ -z "$artifact_number" ]; then
  artifact_number=1
fi
# Plans use (current - 1) to stay in the same round as research
plan_artifact_number=$(( artifact_number - 1 ))
[ "$plan_artifact_number" -lt 1 ] && plan_artifact_number=1
plan_padded=$(printf "%02d" "$plan_artifact_number")

---

Stage 3b: Find Research Report and Prior Plan

padded_num=$(printf "%03d" "$task_number")
task_dir="specs/${padded_num}_${project_name}"

# Find latest research report
research_path=$(ls "${task_dir}/reports/"*.md 2>/dev/null | sort | tail -1)

# Find latest prior plan
prior_plan_path=$(ls "${task_dir}/plans/"*.md 2>/dev/null | sort | tail -1)

---

Stage 4a: Memory Retrieval (Auto)

if [ "$clean_flag" != "true" ]; then
  memory_context=$(bash .claude/scripts/memory-retrieve.sh "$description" "$task_type" "" 2>/dev/null) || memory_context=""
fi

Literature Detection and Injection (Stage 4a, shared block)

Follow @.claude/context/patterns/lit-stage4a-flow.md in full to resolve --lit and set lit_context: call literature-lit-flag-resolve.sh, branch on all six directives (LIT_DISABLED, SUBINDEX_PRESENT, GLOBAL_MISSING, PROMPT_NEEDED, AUTONOMOUS_GLOBAL, SPARSE_PROMPT_NEEDED), issue the real four-option AskUserQuestion for the two interactive directives (including the "Search online to ingest" option wired to the STABLE-CONTRACT literature-ingest-online.sh bridge), apply the two-checkpoint sparse re-prompt after "Use global corpus now", and take the deterministic [lit:auto] autonomous fallback when orchestrator_mode == "true" (never calling AskUserQuestion in that case). This skill supplies the shared block's preconditions: lit_flag, description, and orchestrator_mode (read from the delegation context; default "false" when unset).

Note: lit_flag is independent of clean_flag. Using --clean --lit suppresses memory retrieval but still injects literature briefing. Literature briefing is gated solely on lit_flag == "true".

---

Stage 4: Prepare Delegation Context

Pass H8 plan requirements explicitly in the delegation context:

{
  "session_id": "{session_id}",
  "delegation_depth": 1,
  "delegation_path": ["orchestrator", "plan", "skill-planner-hard"],
  "timeout": 3600,
  "task_context": {
    "task_number": N,
    "task_name": "{project_name}",
    "description": "{description}",
    "task_type": "{task_type}"
  },
  "artifact_number": "{plan_artifact_number}",
  "research_path": "{research_path or null}",
  "prior_plan_path": "{prior_plan_path or null}",
  "effort_flag": "hard",
  "model_flag": "{model_flag from command, null if not set}",
  "roadmap_path": "specs/ROADMAP.md",
  "roadmap_flag": "{roadmap_flag from command}",
  "metadata_file_path": "specs/{NNN}_{SLUG}/.return-meta.json",
  "hard_mode_requirements": {
    "phase_sizing_constraint": "Each phase must be completable in one agent run (~100-500 lines output)",
    "postmortem_constraints_required": true,
    "preserved_assets_accounting": "Required when prior plan exists",
    "source_to_implementation_mapping": "Required for Tier 1/2 reference tasks",
    "wave_map_required": true
  }
}

---

Stage 4b: Read Format Specification

format_content=$(cat .claude/context/formats/plan-format.md)

---

Stage 5: Invoke Subagent

Tool: Agent
Parameters:
  - subagent_type: "planner-hard-agent"
  - prompt: [task_context, delegation_context, format specification, memory_context, lit_context]
  - description: "Create hard-mode implementation plan for task {N}"

If lit_context is non-empty, inject it as a <literature-briefing> block after the memory context and before the task-specific instructions.

---

Stage 5b: Self-Execution Fallback

Follow @.claude/context/patterns/skill-self-execution-fallback.md in full. This skill's success status value for that block's write obligation is "planned".

---

Postflight (ALWAYS EXECUTE)

Stage 6: Parse Subagent Return

metadata_file="specs/${padded_num}_${project_name}/.return-meta.json"

if [ -f "$metadata_file" ] && jq empty "$metadata_file" 2>/dev/null; then
    status=$(jq -r '.status' "$metadata_file")
    artifact_path=$(jq -r '.artifacts[0].path // ""' "$metadata_file")
    artifact_type=$(jq -r '.artifacts[0].type // ""' "$metadata_file")
    artifact_summary=$(jq -r '.artifacts[0].summary // ""' "$metadata_file")
    memory_candidates=$(jq -c '.memory_candidates // []' "$metadata_file")
    postmortem_rules_count=$(jq -r '.postmortem_rules_count // 0' "$metadata_file")
    echo "[hard-mode] Postmortem rules added to plan: $postmortem_rules_count" >&2
else
    status="failed"
fi

---

Stage 6a: Validate Artifact Content (non-blocking)

if [ "$status" = "planned" ] && [ -n "$artifact_path" ] && [ -f "$artifact_path" ]; then
    bash .claude/scripts/validate-artifact.sh "$artifact_path" plan --fix || true
fi

---

Stage 6b: Skeleton Task Allocation (H8 escape valve)

Duplicate-with-modification of skill-spawn/SKILL.md Stages 7-11 (do NOT extract a shared helper — this is a deliberate lower-risk, smaller-diff first cut; revisit only if a second consumer appears). Structurally identical, EXCEPT the dependency direction is REVERSED (see below) and the artifact consumed is .skeleton-return.json rather than .spawn-return.json.

Runs only when planner-hard-agent (Stage 4a of planner-hard-agent.md) declared a skeleton plan. No-ops cleanly otherwise.

skeleton_file="specs/${padded_num}_${project_name}/.skeleton-return.json"

if [ -f "$skeleton_file" ] && jq empty "$skeleton_file" 2>/dev/null; then
  new_tasks=$(jq -r '.new_tasks' "$skeleton_file")
  task_count=$(jq '.new_tasks | length' "$skeleton_file")

  if [ "$task_count" -gt 0 ]; then
    dependency_order=$(jq -r '.dependency_order' "$skeleton_file")

    # Stage 6b-i: Get next task numbers (mirrors skill-spawn Stage 8)
    next_num=$(jq -r '.next_project_number' specs/state.json)

    # Stage 6b-ii: Apply topological sort (mirrors skill-spawn Stage 9)
    # dependency_order is already topologically sorted (foundational first).
    declare -A task_num_map
    order_idx=0
    for idx in $(echo "$dependency_order" | jq -r '.[]'); do
        task_num_map[$idx]=$((next_num + order_idx))
        order_idx=$((order_idx + 1))
    done

    # Stage 6b-iii: Create new task directories (mirrors skill-spawn Stage 10)
    for idx in $(echo "$dependency_order" | jq -r '.[]'); do
        new_task_num=${task_num_map[$idx]}
        new_padded=$(printf "%03d" "$new_task_num")
        task_title=$(jq -r --argjson i "$idx" '.new_tasks[$i].title' "$skeleton_file")
        task_slug=$(echo "$task_title" | tr '[:upper:]' '[:lower:]' | tr ' ' '_' | sed 's/[^a-z0-9_]//g')
        mkdir -p "specs/${new_padded}_${task_slug}/reports"
    done

    # Stage 6b-iv: Update state.json with new tasks (mirrors skill-spawn Stage 11), BUT with the
    # SETTLED REVERSED dependency direction: each follow-up task's `dependencies` includes the
    # SKELETON (current) task number, NOT sibling new_tasks that gate it the spawn-agent way.
    # This is the inverse of skill-spawn Stage 13 -- copying that step verbatim here would wire
