synthesize

synthesize is a skill for Claude Code from juicesharp/rpiv-mono. It costs 162 tokens per session (3,643 once invoked), scanned A, original, MIT.

A planning step that combines several independent design documents into one phased implementation plan. It resolves overlaps between work areas and orders the phases around their dependencies.

In plain words
What is it for?
Use it to merge per-area designs and supporting research into a complete plan, or to create a partial plan for one cluster of related work.
Why use it?
Separate teams or agents may design related parts without seeing each other's decisions. This creates a single plan that explains how those parts fit together and what should happen first.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

synthesize scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Synthesize

You merge several independent per-slice designs into one coherent phased plan. One pass. You do not redesign a slice or write code — you reconcile and sequence what the slice designs already decided. This is the fan-in barrier: each design was produced blind to the others, so your job is to make them fit together. No subagents, no self-review — the workflow's grade panel judges the merged plan.

Input

$ARGUMENTS — flags (the orchestrator wires them from the fan-in):

  • --designs <path> (repeats) — per-slice design docs from the design fanout.
  • --subplans <path> (repeats) — partial sub-plans from a cluster fanout (root mode).
  • --research <path> (optional) — the research the slices rest on, for cross-slice constraints.
  • --as-subplan (flag) — emit a sub-plan (partial mode) instead of a full plan.
  • --cluster <k> (optional, partial mode) — the ordinal written into the sub-plan's _cluster-<k>.md filename. The cluster fanout supplies it; for manual partial invocation pick an unused <k> (scan .rpiv/artifacts/subplans/ for existing *_cluster-<k>.md and take the next unused positive integer) so a re-dispatched pass writes a distinct file and never clobbers a sibling sub-plan.

If neither --designs nor --subplans is present, print an error and stop.

Modes

Pick the mode from the flags — the work is the same fan-in reconciliation at three scales:

Mode Selected by Reads Writes to Output kind
Flat (default) --designs only every design .rpiv/artifacts/plans/ full plan
Partial (per-cluster) --designs … --as-subplan one cluster's designs .rpiv/artifacts/subplans/ sub-plan
Root (merge) --subplans … the cluster sub-plans .rpiv/artifacts/plans/ full plan

Hierarchical synthesis (partial → root) bounds each pass's context: a partial sees only its cluster's designs and exports the seams other clusters integrate with; the root merges the compact sub-plans (their summary + exports + phases), never re-reading every design. Flat mode is the single-pass form for small slice maps.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

synthesize is a skill published in the GitHub repository juicesharp/rpiv-mono (779 stars, last pushed today), licensed MIT. It adds 162 tokens to every session and 3,643 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
