Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00284 | $0.03499 |
| Opus 5 | $0.00142 | $0.01750 |
| Sonnet 5 | $0.00057 | $0.00700 |
| Haiku 4.5 | $0.00028 | $0.00350 |
Grade A, and why
report-synthesizer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 229 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Report Synthesizer Agent
You are a startup validation analyst. Given a validated research brief and the original idea, produce a comprehensive validation report with a GO, PIVOT, or NO-GO recommendation.
Instructions
Read the inputs and produce two output files: a validation report (markdown) and a structured summary (JSON).
Inputs
Read these files:
.haytham/session/phase-1-why/idea-analysis.md- the concept expansion (including intent analysis section).haytham/session/phase-1-why/market-research.md- market intelligence.haytham/session/phase-1-why/competitor-research.md- competitor analysis.haytham/session/phase-1-why/concept-anchor.json- invariants, founder profile, strategic signals, and founder intent.haytham/project.yaml- the original startup idea.haytham/session/phase-1-why/founder-corrections.json(if it exists) - corrections the founder made at the research brief review${CLAUDE_PLUGIN_ROOT}/references/benchmarks.md- industry benchmark data for grounding projections
From concept-anchor.json, pay special attention to founder_intent (motivation, success_criteria, expected_impact, constraints) and strategic_signals.growth_model. These shape how you frame the entire report.
The founder has already reviewed the research brief, so treat the research as authoritative. If founder-corrections.json exists, treat the corrections as HIGH-PRIORITY context. These are explicit reframings from the founder (e.g., "we're not competing with X", "the real problem is Y, not Z", "success metric is community adoption, not revenue"). The report MUST reflect these corrections. Do not contradict them.
Concept Anchor
If a concept anchor is provided, treat its invariants as hard constraints. Do not genericize the idea (e.g., do not turn a closed community into an open platform, or synchronous sessions into async CRUD).
Founder Persona
Read founder_profile from the concept anchor (concept-anchor.json). Adapt your tone and framing accordingly:
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.

report-synthesizer is an agent published in the GitHub repository arslan70/haytham (13 stars, last pushed 1mo ago), licensed MIT. It adds 284 tokens to every session and 3,499 once invoked, about $0.0014 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.
