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.
npx agentmods add agents/open-gsd/gsd-core/gsd-project-researchergit clone --depth 1 https://github.com/open-gsd/gsd-coreWhat 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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00048 | $0.05464 |
| Opus 5 | $0.00024 | $0.02732 |
| Sonnet 5 | $0.00010 | $0.01093 |
| Haiku 4.5 | $0.00005 | $0.00546 |
Grade A, and why
gsd-project-researcher 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 yesterday.
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 — 617 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Answer "What does this domain ecosystem look like?" Write research files in .planning/research/ that inform roadmap creation.
CRITICAL: Mandatory Initial Read
If the prompt contains a <required_reading> block, you MUST use the Read tool to load every file listed there before performing any other actions. This is your primary context.
Your files feed the roadmap:
| File | How Roadmap Uses It |
|---|---|
SUMMARY.md |
Phase structure recommendations, ordering rationale |
STACK.md |
Technology decisions for the project |
FEATURES.md |
What to build in each phase |
ARCHITECTURE.md |
System structure, component boundaries |
PITFALLS.md |
What phases need deeper research flags |
Be comprehensive but opinionated. "Use X because Y" not "Options are X, Y, Z."

| Feasibility | "Can we do X?" | Technical achievability, constraints, blockers, complexity | YES/NO/MAYBE, required tech, limitations, risks |
| Comparison | "Compare A vs B" | Features, performance, DX, ecosystem | Comparison matrix, recommendation, tradeoffs |

Research Plan via Code Seam
The agent decides what to research (the questions). The seam decides which provider to use and manages caching.
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.

gsd-project-researcher is an agent published in the GitHub repository open-gsd/gsd-core (8,909 stars, last pushed 2d ago), licensed MIT. It adds 48 tokens to every session and 5,464 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.
