arch-synthesize

arch-synthesize is a command for Claude Code from davistroy/claude-marketplace. It costs 25 tokens per session (499 once invoked), scanned A, original, MIT.

A command that rebuilds an architecture review’s executive summary from its existing domain findings. It combines available agent reports and notes which standard review areas were not covered.

In plain words
What is it for?
Use it after editing findings, rerunning a single architecture agent, or resolving disagreements between review results.
Why use it?
It lets you update the overall report after changing findings or rerunning one review area, without repeating every review.

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

arch-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 11d 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.

What it actually says

Architecture Review — Synthesize

Re-run synthesis from existing findings. Use after manually editing domain findings, re-running a single agent with /arch-review-single, or resolving cross-domain conflicts offline.

Usage: /arch-synthesize <path-to-target>


Parse target path from: $ARGUMENTS

  1. Validate <target-path>/arch-review/findings/ exists — if not, stop and suggest running /arch-review first

  2. Discover and merge per-agent coverage meta:

ls <target-path>/arch-review/findings/*.meta.json 2>/dev/null || echo "No *.meta.json files found — agent meta unavailable"

Read each <agent-name>.meta.json file found and merge their entries into a single coverage map keyed by agent name. Only a subset of the standard 9 agents may have run — an agent missing its .meta.json file is not an error; treat it the same as a missing findings file (flag as "Domain not reviewed" per step 4).

  1. List all findings files present:
ls <target-path>/arch-review/findings/*.md 2>/dev/null
  1. Note any agents from the standard 9 whose findings file is missing — flag in report header as "Domain not reviewed"

  2. Read all present findings files

  3. Run cross-domain conflict detection:

    • Identify any finding in one domain that contradicts or creates tension with a finding in another
    • Resolve using business impact as tiebreaker
    • Document any unresolved conflicts in the executive summary
  4. Produce fresh <target-path>/arch-review/reports/executive-summary.md — overwrite existing

    • Begin with the Review Coverage table rendered from the merged per-agent meta (step 2)
    • Follow the full report structure from /arch-review
  5. Print terminal summary:

    • Total findings by severity across all available domains
    • Any domains with Low/Medium confidence flagged for follow-up
    • Path to executive summary

Do not re-run any domain agents. Synthesize from what exists.

What this file has done since we first saw it

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.
