Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00045 | $0.00459 |
| Opus 5 | $0.00023 | $0.00230 |
| Sonnet 5 | $0.00009 | $0.00092 |
| Haiku 4.5 | $0.00005 | $0.00046 |
Grade A, and why
synthesis-response-merger 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
Response Merger
Merge multiple LLM responses into a single, comprehensive, unified document that preserves all detail from every input.
Input
A document containing one or more prompts and their corresponding responses from one or more LLM engines. This is referred to as the prompt-response document.
Process
Step 1: Read thoroughly
Read the entire prompt-response document. Identify each distinct prompt and every response generated for it.
Step 2: Plan the merge
Before writing, produce a plan:
- How will key points from each response be integrated?
- Where does useful context or framing from the original prompts belong?
- What organizational structure best serves the combined content?
- Where do responses overlap, and where do they contribute unique material?
Step 3: Write the unified document
Follow the plan and produce the unified output.
Critical rules:
- Do NOT simplify, shorten, or reduce any level of detail. This is a merge, not a summary.
- Do NOT omit minor details from any individual response. Every detail matters.
- The unified document must be significantly longer and more detailed than even the longest single input response.
- No section of the output should have less detail than the corresponding section in any input response.
- Incorporate relevant context and framing from the original prompts where it aids understanding.
- Format for readability: use headings, lists, and structure appropriate to the content.
Output structure
- Plan -- the integration plan (brief, for transparency)
- Unified document -- the comprehensive merged result

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

synthesis-response-merger is a skill published in the GitHub repository synthesisengineering/synthesis-skills (18 stars, last pushed today), licensed Apache-2.0. It adds 45 tokens to every session and 459 once invoked, about $0.0002 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.
