Iterate on Plan

Iteratively refine an OpenSpec proposal after /plan-feature creates it. Each iteration reviews the proposal documents, identifies plan quality issues, implements fixes, and commits — repeating until only low-criticality findings remain or max iterations are reached.

Arguments

$ARGUMENTS - OpenSpec change-id (required), optionally followed by:

• --max <N> (default: 3)
• --threshold <level> (default: "medium"; values: "critical", "high", "medium", "low")
• --vendor-review — dispatch multi-vendor review after iterate loop converges; automatic in coordinated tier
• --prototype-context <change-id> — convergence mode (added by add-prototyping-stage / D1). When present, the skill loads prototype-findings.md, variant branch diffs, and validation reports as additional context, then emits convergence.* findings to refine design.md and tasks.md based on the picks captured by /prototype-feature. The change-id MUST match the iteration target. Fails fast if no findings file exists.

Prerequisites

• OpenSpec proposal exists at openspec/changes/<change-id>/ with at least proposal.md, tasks.md, and one spec delta
• Run /plan-feature first if no proposal exists
• Proposal has NOT yet been approved (this skill refines before approval)
• For --prototype-context: /prototype-feature <change-id> must have been run first and produced openspec/changes/<change-id>/prototype-findings.md

Provider-Neutral Dispatch

When this skill delegates analysis work, treat the provider-neutral dispatch adapter as the canonical cross-provider path. Claude Code, Codex, Antigravity, Grok, and Pi are first-class providers when configured; Claude-style Task(...) or Agent(...) snippets are provider-specific examples, with inline execution as the fallback.

OpenSpec Execution Preference

Use OpenSpec-generated runtime assets first, then CLI fallback:

• Claude: .claude/commands/opsx/*.md or .claude/skills/openspec-*/SKILL.md
• Codex: .codex/skills/openspec-*/SKILL.md
• Fallback: direct openspec CLI commands

Coordinator Integration (Optional)

Use docs/coordination-detection-template.md as the shared detection preamble.

• Detect transport and capability flags at skill start
• Execute hooks only when the matching CAN_* flag is true
• If coordinator is unavailable, continue with standalone behavior

Local CLI Mutation Boundary

Plan iteration writes proposal, design, task, spec, findings, and session-log artifacts. In local CLI execution, those writes MUST run in a managed worktree and MUST NOT commit directly to local main.

After parsing CHANGE_ID, enter or verify the feature worktree before baseline validation, findings generation, or edits:

eval "$(python3 "<skill-base-dir>/../worktree/scripts/worktree.py" setup "$CHANGE_ID")"
cd "$WORKTREE_PATH"
python3 "<skill-base-dir>/../shared/checkout_policy.py" require-mutation
eval "$(python3 "<skill-base-dir>/../worktree/scripts/worktree.py" resolve-branch "$CHANGE_ID" --parent)"
FEATURE_BRANCH="$BRANCH"

All commits from this skill land on $FEATURE_BRANCH for PR review.

Steps

0. Detect Coordinator, Read Handoff, Recall Memory

At skill start, run the coordination detection preamble and set:

• COORDINATOR_AVAILABLE
• COORDINATION_TRANSPORT (mcp|http|none)
• CAN_LOCK, CAN_QUEUE_WORK, CAN_HANDOFF, CAN_MEMORY, CAN_GUARDRAILS

If CAN_HANDOFF=true, read recent handoff context:

• MCP path: read_handoff
• HTTP path: "<skill-base-dir>/../coordination-bridge/scripts/coordination_bridge.py" try_handoff_read(...)

If CAN_MEMORY=true, recall relevant plan-iteration memories:

• MCP path: recall
• HTTP path: "<skill-base-dir>/../coordination-bridge/scripts/coordination_bridge.py" try_recall(...)

On recall/handoff failure, continue with standalone iteration and log informationally.

1. Determine Change ID and Configuration

# Parse change-id from argument
CHANGE_ID=${ARGUMENTS%% *}

# Defaults
MAX_ITERATIONS=3
THRESHOLD="medium"  # critical > high > medium > low

Parse optional flags from $ARGUMENTS:

• --max <N> overrides MAX_ITERATIONS
• --threshold <level> overrides THRESHOLD
• --vendor-review sets VENDOR_REVIEW=true

# Vendor review: explicit flag OR auto-enable in coordinated tier
VENDOR_REVIEW=false
if [[ "$ARGUMENTS" == *"--vendor-review"* ]] || [[ "$COORDINATOR_AVAILABLE" == "true" ]]; then
  VENDOR_REVIEW=true
fi

1.5. Enter Planning Worktree

eval "$(python3 "<skill-base-dir>/../worktree/scripts/worktree.py" setup "$CHANGE_ID")"
cd "$WORKTREE_PATH"
python3 "<skill-base-dir>/../shared/checkout_policy.py" require-mutation
eval "$(python3 "<skill-base-dir>/../worktree/scripts/worktree.py" resolve-branch "$CHANGE_ID" --parent)"
FEATURE_BRANCH="$BRANCH"

All subsequent steps run inside the worktree. Do not switch back to the shared checkout for file writes, validation artifacts, or commits.

2. Verify Proposal Exists

# Verify proposal exists
openspec show $CHANGE_ID

# Verify core files exist
ls openspec/changes/$CHANGE_ID/proposal.md
ls openspec/changes/$CHANGE_ID/tasks.md
ls openspec/changes/$CHANGE_ID/specs/

If any core files are missing, abort and recommend running /plan-feature first.

3. Run Baseline Validation

# Strict validation as starting point
openspec validate $CHANGE_ID --strict

Record any validation failures. These become automatic critical-level findings in the first iteration.

3.5. Prepare Findings Artifact

Preferred path:

• Use the runtime-native continue/findings workflow (opsx:continue equivalent) to create or extend plan-findings.

CLI fallback path:

openspec instructions plan-findings --change "$CHANGE_ID"
openspec status --change "$CHANGE_ID"

Ensure openspec/changes/<change-id>/plan-findings.md exists and append each iteration's findings there.

3.7. Load Prototype Context (Conditional — Convergence Mode)

Skipped when --prototype-context is NOT in argv. The convergence path is always explicit per D1 / spec; iterate-on-plan does NOT auto-discover prototype-findings.md.

When --prototype-context <change-id> is present, load the artifacts the /prototype-feature skill produced:

from prototype_context import PrototypeContextMissing, load_prototype_context

try:
    ctx = load_prototype_context(
        change_dir=Path("openspec/changes") / PROTOTYPE_CONTEXT_CHANGE_ID
    )
except PrototypeContextMissing as exc:
    # Fail fast — the user explicitly asked for prototype-aware refinement,
    # so silently downgrading to non-convergence iteration would be wrong.
    raise SystemExit(f"--prototype-context: {exc}")

ctx.descriptors carries the parsed VariantDescriptors; ctx.synthesis_plan carries the per-aspect picks and pre-classified convergence.* recommended findings (computed via parallel-infrastructure.synthesize_variants).

In step 5 (Review and Analyze), seed the iteration's finding list with ctx.synthesis_plan["recommended_findings"] so they appear alongside the standard clarity/feasibility/etc findings the analyzer produces. The convergence findings drive design.md and tasks.md refinements that synthesize the picked aspects from the variant branches.

Also load the per-variant branch diffs as context (read-only — diffs are inputs, not edits):

for desc in $(ctx.descriptors); do
  git diff main..."${desc.branch}" > /tmp/prototype-diff-"${desc.variant_id}".patch
done

Refinement commits land on $FEATURE_BRANCH — never on prototype branches. The prototype branches stay untouched until /cleanup-feature deletes them.

Spec scenarios covered: ConvergenceViaIterateOnPlan.convergence-mode-activated, convergence-without-context (the negative — not loading anything), missing-prototype-artifacts (fail fast).

4. Begin Iteration Loop

ITERATION=1

---

5. Review and Analyze (Parallel Analysis Option)

Read all proposal documents to understand intent and current quality. For complex proposals, use parallel Task(Explore) agents to analyze different quality dimensions:

Sequential approach (default for simple proposals):

• Read openspec/changes/<change-id>/proposal.md
• Read openspec/changes/<change-id>/tasks.md
• Read openspec/changes/<change-id>/design.md (if exists)
• Read all spec deltas in openspec/changes/<change-id>/specs/*/spec.md
• Read existing specs in openspec/specs/ for capabilities referenced in the proposal's Impact section

Parallel approach (for complex proposals with 5+ tasks or 3+ spec deltas):

Resolve the analyst archetype before dispatching:

import sys
from pathlib import Path

bridge_scripts = Path("<skill-base-dir>").parent / "coordination-bridge" / "scripts"
sys.path.insert(0, str(bridge_scripts))
import coordination_bridge

resolved = coordination_bridge.try_resolve_archetype_for_phase("PLAN_ITERATE", {})
analyst_model = resolved["model"] if resolved else None

If resolution is unavailable, omit model= from Task.

# Launch parallel analysis agents (single message, multiple Task calls)
Task(subagent_type="Explore", model=analyst_model, prompt="Analyze openspec/changes/$CHANGE_ID/ for COMPLETENESS issues: missing requirements, unaddressed edge cases, gaps in impact analysis, requirements without scenarios", run_in_background=true)
Task(subagent_type="Explore", model=analyst_model, prompt="Analyze openspec/changes/$CHANGE_ID/ for CLARITY and CONSISTENCY issues: ambiguous wording, vague scenarios, contradictions between documents", run_in_background=true)
Task(subagent_type="Explore", model=analyst_model, prompt="Analyze openspec/changes/$CHANGE_ID/tasks.md for FEASIBILITY and PARALLELIZABILITY: task size, dependencies, file overlap that would cause merge conflicts", run_in_background=true)
Task(subagent_type="Explore", model=analyst_model, prompt="Analyze openspec/changes/$CHANGE_ID/ for TESTABILITY: scenarios that can't be verified, subjective language like 'properly' or 'correctly'", run_in_background=true)
Task(subagent_type="Explore", model=analyst_model, prompt="Analyze openspec/changes/$CHANGE_ID/ for SECURITY and PERFORMANCE issues: missing auth/authorization for endpoints, secrets in config, unvalidated inputs, unbounded queries, missing pagination, sync where async needed", run_in_background=true)

Analysis Synthesis:

1. Wait for all TaskOutput results (if parallel)
2. Merge findings, deduplicate, and assign criticality levels
3. Produce the structured plan analysis below

Produce a structured plan analysis with findings in this format:

#	Type	Criticality	Description	Proposed Fix
1	completeness/clarity/feasibility/scope/consistency/testability/parallelizability/assumptions/security/performance	critical/high/medium/low	What the issue is	How to fix it

Type categories:

• completeness: Missing requirements, unaddressed edge cases, gaps in impact analysis, missing spec deltas for affected capabilities, requirements without scenarios
• clarity: Ambiguous requirement wording, vague WHEN/THEN scenarios, unclear task descriptions, missing context in proposal.md Why section, requirements not using SHALL/MUST
• feasibility: Tasks too large to implement atomically, unrealistic scope, missing technical constraints, undocumented dependencies between tasks
• scope: Scope creep beyond stated goals, mixing unrelated concerns, non-goals that should be explicit, tasks that don't trace back to any requirement
• consistency: Contradictions between proposal.md and design.md, requirement wording mismatches across documents, affected specs listed in Impact but no corresponding delta (or vice versa), duplicate requirements
• testability: Scenarios that can't be verified, requirements without measurable acceptance criteria, WHEN/THEN using subjective language ("properly", "correctly", "as expected")
• parallelizability: How well the task decomposition supports parallel multi-agent execution via /parallel-implement. Evaluates whether tasks have explicit dependency declarations, whether task scopes are isolated to separate modules/files (no shared-file overlap that would cause merge conflicts), whether tasks are granular enough for independent agent assignment, and whether sequencing maximizes concurrent execution width
• assumptions: Implicit decisions that could reasonably go either way — assumed authentication mechanism, data format, deployment target, backward-compatibility requirement, performance threshold, technology choice, or scope boundary. When an assumption is identified that has multiple valid interpretations, it MUST be surfaced to the user via AskUserQuestion rather than documented and moved on from. Present the assumption, the alternatives, and ask the user to decide.
• security: Missing authentication/authorization for new endpoints, secrets in configuration or code, unvalidated inputs at system boundaries, OWASP top-10 considerations not addressed, missing threat model for new attack surface, no encryption for sensitive data in transit or at rest
• performance: Unbounded queries or loops in design, missing pagination for list operations, synchronous processing where async is needed, missing caching strategy for hot paths, no rate limiting for public endpoints, O(n^2) or worse algorithms in design without justification

Criticality levels:

• critical: openspec validate --strict failures, missing spec deltas for capabilities listed in Impact, requirements without any scenarios, proposal.md missing required sections (Why, What Changes, Impact), authentication bypass or missing auth on endpoints handling sensitive data
• high: Ambiguous requirements that could be implemented multiple valid ways, tasks not traceable to requirements, scenarios using subjective/unmeasurable criteria, contradictions between documents, tasks with implicit shared-state or shared-file dependencies that would cause merge conflicts if parallelized, unstated assumptions about scope or technology choice that could invalidate the plan if wrong, secrets in configuration without secret management, unbounded queries on large datasets
• medium: Missing edge-case scenarios (only success path covered), tasks too coarse for single-commit implementation, design.md needed but absent, incomplete impact analysis, tasks missing explicit dependency annotations, tasks that could be split into independent units for better parallelism, missing pagination for list endpoints, missing monitoring requirements for new services
• low: Wording polish, minor formatting, task ordering optimization for parallel execution, optional design.md sections, missing caching considerations

Plan smells to check for:

• Giant task (spans multiple systems or modules)
• Orphan requirement (requirement in spec delta with no corresponding task)
• Orphan task (task with no corresponding requirement)
• Vague scenario (WHEN/THEN using words like "appropriate", "correctly", "properly", "as expected")
• Missing failure path (only success scenarios, no error/edge-case scenarios)
• Scope leak (tasks or requirements that extend beyond the stated What Changes)
• Impact mismatch (affected specs listed in proposal.md but no spec delta created, or vice versa)
• Design gap (multiple complex decisions without a design.md)
• Implicit dependency (tasks that modify the same files or shared state without explicit ordering — would cause merge conflicts in parallel execution)
• Monolithic task (single task that could be decomposed into independent subtasks for parallel agents)
• Missing dependency graph (tasks lack explicit dependency annotations needed by /parallel-implement and the coordinator's blocked_by field)
• Coupled scope (tasks that modify overlapping files or modules, preventing isolated worktree execution)
• Unstated assumption (plan proceeds on an assumption about scope, technology choice, or constraint that was never confirmed with the user — could validly go multiple ways)
• Unprotected endpoint (new API endpoint without authentication/authorization requirement stated)
• Secret in config (credentials or API keys referenced in configuration without secret management)
• Missing input validation (system boundary input accepted without validation requirement in spec)
• Missing pagination (list operation returning unbounded results without pagination or size limits)
• Missing observability (new service or endpoint without monitoring, logging, or alerting requirements)

Schema type mapping (for translating plan findings to review-findings.schema.json types at the dispatch/consensus boundary):

Plan Dimension	Schema Type(s)	Notes
completeness	spec_gap	Missing requirements = spec gap. Use observability/resilience/compatibility when the missing content is specifically about those concerns.
clarity	spec_gap, style	Ambiguous wording = spec_gap; formatting = style
feasibility	architecture, performance	Infeasible designs are usually architectural or performance-bound
scope	spec_gap, correctness	Scope creep = spec_gap; scope leak = correctness
consistency	contract_mismatch, correctness	Cross-document contradictions
testability	spec_gap	Untestable requirement = incomplete spec
parallelizability	architecture	Task decomposition is architectural
assumptions	architecture, security, compatibility	Map to the schema type matching the assumption's subject
security	security	Direct mapping
performance	performance	Direct mapping

Convergence finding taxonomy (only emitted in convergence mode — when --prototype-context was supplied; produced by parallel-infrastructure.synthesize_variants and seeded into the iteration's findings list at step 3.7):

Finding Type	When Emitted	Resolution Hint
convergence.merge-<aspect>-<vA>-and-<vB>	Multiple variants picked for the same aspect (data_model / api / tests / layout) — humans wanted bits of both	Refine design.md to combine the picked elements; don't silently pick one
convergence.rewrite-<aspect>	Zero variants picked for an aspect — none of them got it right	Rewrite the aspect in design.md from other context (proposal, spec deltas) — don't carry forward any variant's take
convergence.prefer-variant-<aspect>	Single variant picked for an aspect (default source recorded in synthesis_plan)	The pick is unambiguous; refine to use that variant's approach
workflow.prototype-recommended	NOT a convergence finding — the inverse advisory emitted by step 6.5 when this iteration produces ≥3 high-criticality clarity+feasibility findings (D8)	Suggest running /prototype-feature BEFORE the next iteration; never auto-trigger

6. Check Termination Conditions

Stop iterating if:

• All findings are below the criticality threshold → present summary and list remaining low-criticality findings for optional manual review
• ITERATION > MAX_ITERATIONS → present summary and list any unaddressed findings

If stopping, skip to the After Loop section below.

Otherwise, continue to step 7.

6.5. Maybe Emit Prototype-Recommended Advisory (D8)

After the standard finding analysis in step 5 produces this iteration's findings list, run the prototype-recommended emitter:

from prototype_recommended import maybe_emit_prototype_recommended

advisory = maybe_emit_prototype_recommended(findings, change_id=CHANGE_ID)
if advisory is not None:
    findings.append(advisory)

The emitter returns a single workflow.prototype-recommended finding when this iteration produced ≥3 high-criticality findings in the clarity or feasibility dimensions (combined). The advisory:

• Has criticality=low so it sorts to the bottom of the report (it's a hint, not a fix-required item)
• Names the triggering finding types in its description so the human knows WHY prototyping was suggested
• Suggests /prototype-feature <change-id> as the next command — but never invokes it automatically (D8 is opt-in)

If the threshold is not met, the emitter returns None and nothing is appended.

Spec scenarios covered: PrototypeRecommendationSignal.threshold-met, threshold-not-met, advisory-only.

7. Implement Improvements

Fix all findings at or above the criticality threshold by modifying the proposal documents:

• proposal.md: Add missing Why context, expand What Changes, correct Impact section
• tasks.md: Split giant tasks, add missing tasks for orphan requirements, add explicit ordering and dependency notes, improve verifiability, restructure for parallel execution where possible
• design.md: Create if needed (per criteria below), add missing decision rationale, document alternatives considered, add risks/trade-offs
• Spec deltas: Add missing requirements, add WHEN/THEN scenarios for uncovered paths, fix requirement wording to use SHALL/MUST, add failure/edge-case scenarios, split monolithic spec files
• Assumptions: For each assumption-type finding, use AskUserQuestion to surface it interactively. Present the implicit assumption, explain why it matters (what would change if the assumption is wrong), and offer the alternatives as selectable options. Wait for the user's response. Then update the relevant document (proposal.md, design.md, or spec delta) to convert the assumption into an explicit, documented decision with rationale.

When to create design.md (if one does not exist):

• Change affects multiple capabilities or introduces a new pattern
• New external dependency or significant data model changes
• Security, performance, or migration concerns
• Multiple technical decisions that need documented rationale

For findings that are outside the scope of the current proposal:

• Flag as "out of scope"
• Recommend creating a new OpenSpec proposal
• Do NOT expand the current proposal to address them

8. Run Quality Checks

# Validate proposal structure
openspec validate $CHANGE_ID --strict

Additionally verify:

• Scenario coverage: Every requirement has at least one success and one failure/edge scenario
• Requirement completeness: All requirements use SHALL/MUST, all have clear subjects
• Task granularity: Each task could reasonably be completed in a single commit
• Task traceability: Every task maps to at least one requirement, every requirement maps to at least one task
• Cross-document consistency: Impact section matches actual spec deltas, proposal.md describes all spec delta changes
• Design rationale: If design.md exists, each decision has at least one alternative considered
• Parallelizability: Every task either (a) is independent (no shared files/state with other tasks) or (b) has explicit dependency annotation. Produce a dependency graph summary:
  • Independent: N tasks | Sequential chains: M | Max parallel width: W
  • Identify tasks that modify the same files — these need explicit sequencing or scope restructuring to avoid merge conflicts during /parallel-implement
  • If all tasks are purely sequential with no parallelism possible, flag as medium finding

Fix any failures before proceeding. If fixes introduce new issues, address them within this iteration.

8.5. Append Session Log

Construct a PhaseRecord for the Plan Iteration <N> phase and call write_both(). The iteration number is auto-computed from prior Plan Iteration entries in the session-log so the agent does not have to count manually.

Capture from this iteration:

• Decisions — Decisions about which findings to address, which to defer, and how to restructure the proposal.
• Alternatives Considered — Approaches considered and rejected during this iteration.
• Trade-offs — Trade-offs accepted in scoping the iteration.
• Open Questions — Unresolved questions remaining after the iteration.
• Completed Work — Concrete fixes landed in this iteration (per-finding).
• Summary — 2–3 sentences: which findings were addressed, what changed.

Persist via PhaseRecord.write_both():

This step MUST run BEFORE the git add in Step 9 so the session-log entry is included in that commit.

python3 - <<'EOF'
import sys
from pathlib import Path
sys.path.insert(0, str(Path("<skill-base-dir>").parent / "session-log" / "scripts"))
from phase_record import PhaseRecord, Decision, Alternative, TradeOff
from extract_session_log import count_phase_iterations

n = count_phase_iterations(
    "Plan Iteration", "openspec/changes/<change-id>/session-log.md"
) + 1

record = PhaseRecord(
    change_id="<change-id>",
    phase_name=f"Plan Iteration {n}",
    agent_type="<agent-type>",
    summary="<2-3 sentences: findings addressed, what changed>",
    decisions=[
        Decision(title="<title>", rationale="<rationale>"),
    ],
    alternatives=[Alternative(alternative="<approach>", reason="<rejection reason>")],
    trade_offs=[TradeOff(accepted="<X>", over="<Y>", reason="<reason>")],
    open_questions=["<question>"],
    completed_work=["<finding addressed>"],
)
result = record.write_both()
print(f"markdown_path={result.markdown_path}")
print(f"sanitized={result.sanitized}")
print(f"handoff_id={result.handoff_id or '(local fallback)'}")
print(f"handoff_local_path={result.handoff_local_path}")
for w in result.warnings:
    print(f"WARN: {w}", file=sys.stderr)
EOF

write_both() runs three best-effort steps internally: append rendered markdown → sanitize in-place → coordinator handoff (or local fallback at openspec/changes/<change-id>/handoffs/plan-iteration-<n>-<N>.json). Each step logs warnings on failure but does not raise — the workflow continues even if the coordinator is unreachable. The session-log.md is inside openspec/changes/$CHANGE_ID/ so it will be picked up by the existing git add in Step 9.

9. Commit Iteration

# Review all changes
git status
git diff

# Stage proposal document changes only
git add openspec/changes/$CHANGE_ID/

# Commit with structured message
git commit -m "$(cat <<'EOF'
refine(plan): iteration <N> - <summary of key changes>

Iterate-on-plan: <change-id>, iteration <N>/<max>

Findings addressed:
- [<criticality>] <type>: <description>
- [<criticality>] <type>: <description>

Co-Authored-By: Claude <[e-mail]>
EOF
)"

# Increment and loop
ITERATION=$((ITERATION + 1))

Loop back to Step 5.

---

After Loop

10. Multi-Vendor Review (Conditional)

Skip this step if VENDOR_REVIEW=false.

After the iterate loop converges (all findings below threshold) or max iterations are reached, dispatch a multi-vendor review for a final independent validation pass.

10a. Dispatch /parallel-review-plan

Write a review prompt and dispatch to other vendor CLIs:

# Create review prompt for vendor dispatch
mkdir -p openspec/changes/$CHANGE_ID/reviews

cat > openspec/changes/$CHANGE_ID/reviews/review-prompt.md <<'PROMPT'
Review the OpenSpec plan artifacts in openspec/changes/$CHANGE_ID/.
Read proposal.md, tasks.md, design.md (if present), and all spec deltas.
Output ONLY valid JSON conforming to review-findings.schema.json.
Focus on: specification completeness, contract consistency, architecture alignment, security, and work package validity.
PROMPT

# Dispatch to other vendors (excludes current agent's vendor)
python3 "<skill-base-dir>/../parallel-infrastructure/scripts/review_dispatcher.py" \
  --review-type plan \
  --mode review \
  --prompt-file "openspec/changes/$CHANGE_ID/reviews/review-prompt.md" \
  --cwd "$(pwd)" \
  --output-dir "openspec/changes/$CHANGE_ID/reviews" \
  --exclude-vendor claude_code \
  --timeout 600

Also produce your own findings as the primary reviewer (Steps 1-5 of /parallel-review-plan): read plan artifacts, evaluate against the review checklist, and write findings to openspec/changes/$CHANGE_ID/review-findings-plan.json.

10b. Synthesize Consensus

python3 "<skill-base-dir>/../parallel-infrastructure/scripts/consensus_synthesizer.py" \
  --review-type plan \
  --target "$CHANGE_ID" \
  --findings "openspec/changes/$CHANGE_ID/review-findings-plan.json" \
             "openspec/changes/$CHANGE_ID/reviews/findings-"*"-plan.json" \
  --output "openspec/changes/$CHANGE_ID/reviews/consensus-plan.json"

Present consensus summary:

• Confirmed findings (2+ vendors agree) — high confidence
• Unconfirmed findings (single vendor) — lower confidence, warnings
• Disagreements (vendors disagree on disposition) — escalate to human

If no other vendors are available (CLIs not installed), skip dispatch and proceed with single-vendor findings only.

10c. Feed Back Findings Above Remediation Threshold

The remediation threshold is the user's --threshold setting if provided, otherwise medium.

If the consensus or vendor review surfaces new findings at or above the remediation threshold:

1. Append the new findings to openspec/changes/$CHANGE_ID/plan-findings.md
2. Run one additional iterate cycle (Steps 5-9) to address them
3. Commit with message: refine(plan): vendor-review remediation - <summary>
4. Do NOT re-dispatch vendor review (prevents infinite recursion)

If all vendor review findings are below the remediation threshold, proceed to the summary.

---

11. Present Summary

Present a summary of all iterations:

If `CAN_MEMORY=true`, remember iteration outcomes (for example findings counts, key fixes, and residual risks):

- MCP path: `remember`
- HTTP path: `"<skill-base-dir>/../coordination-bridge/scripts/coordination_bridge.py"` `try_remember(...)`

If `CAN_HANDOFF=true`, write a completion handoff containing:

- Iterations performed and findings addressed
- Remaining below-threshold findings (if any)
- Validation status and proposal readiness
- Recommended next command
