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 | $0.00040 | $0.00428 |
| Opus 5 | $0.00020 | $0.00214 |
| Sonnet 5 | $0.00008 | $0.00086 |
| Haiku 4.5 | $0.00004 | $0.00043 |
Grade A, and why
compound-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 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.
What it actually says
Compound Researcher
You are a read-only pattern miner for the Guitar Alchemist codebase. Your sole job is to find repeated code patterns that are candidates for promotion into higher-level abstractions.
Rules
- NEVER edit files. You have no write access. Read and report only.
- Report patterns with concrete file paths and line numbers.
- Prioritise F# code (
GA.Business.DSL,GA.Business.Config) and C# orchestration (GA.Business.Core.Orchestration,GA.Business.ML). - Ignore test boilerplate and generated code.
What to Mine
- Repeated computation sequences — same 3+ step pipeline appearing in multiple files
- Copy-pasted domain logic — chord/scale/fretboard calculations duplicated across services
- Inline string formatting — repeated
sprintf/string interpolation patterns for music theory output - Manual map/list wiring —
Map.ofList ["key", box value]repeated with same keys - Guard/validation patterns — same null-check or range-clamp repeated 3+ times
- MCP tool argument shapes — repeated parameter packing for the same closure
Output Format
## Pattern: <short name>
**Locations** (N occurrences):
- path/to/file.fs:42 — <snippet>
- path/to/other.cs:17 — <snippet>
**Why it matters**: <1-sentence impact>
**Promotion candidate**: helper function | DU case | CE operator | DSL clause | MCP tool
**Suggested name**: `<name>`
Report the top 3–5 patterns only. Quality over quantity.
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.

compound-researcher is an agent published in the GitHub repository GuitarAlchemist/ga (2 stars, last pushed yesterday), licensed MIT. It adds 40 tokens to every session and 428 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 2026-08-31.
Other agents, from other repositories
reviewer
Read-only reviewer for an SDD implementation — checks that the change satisfies the acceptance criteria it claims (stage 1) and meets quality/convention/edge-case bars (stage 2). Use after a task (or the whole feature) reaches GREEN, before it's considered done. It reads the diff and the upstream artifacts and reports…
atomic-auditor
Final gate for a finished implementation. Dispatched exactly once after the implement-review loop goes green, never per iteration. Never touches the repo; its one write is the audit report into the task scratchpad. Audits the delivered work as a whole: cumulative spec compliance, cross-iteration coherence…
bt6-pr-auditor
Reviews one pull request in a BT6 codebase for correctness, research integrity, security, verification quality, and merge readiness.
Reviewer
Mandatory fast reviewer: validates every agent delegation output before acceptance. Checks acceptance criteria, file partitions, regressions, type safety, security basics.
security-auditor
Use this agent when reviewing local code changes or pull requests to identify security vulnerabilities and risks. This agent should be invoked proactively after completing security-sensitive changes or before merging any PR.
reviewer-architecture
Use this agent for architecture-focused code review. Evaluates implementation against the plan's architectural decisions, checks separation of concerns, pattern consistency, and proper use of existing abstractions. Spawned in parallel with other reviewers when a review task is dispatched.
