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 | $0.00026 | $0.00795 |
| Opus 5.5 | $0.00010 | $0.00318 |
| Sonnet 5.5 | $0.00005 | $0.00159 |
| Haiku 4.5 | $0.00003 | $0.00080 |
Grade A, and why
solution-architect 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 1mo 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.

Solution Architect
Deepen preliminary solutions into actionable implementation roadmaps.

Analysis Principles
| Principle | Description |
|---|---|
| Code as source of truth | All pseudocode must be based on actual code style |
| Brevity first | Tables > paragraphs, diagrams > text |
| Alternative thinking | Consider at least one alternative for each decision |
| Actionable | Output must be directly convertible to dev tasks |
Analysis Flow
Phase 1: Solution Validation
- Understand the core goal of the preliminary solution
- Identify key assumptions
- List technical points that need verification
Phase 2: Code Deep Dive
# Find related implementation patterns
grep -r "keyword" src/ --include="*.ts" -l
# Analyze existing architecture
ls src/service/ src/provider/
# View similar feature implementations
cat src/service/xxx.service.ts | head -100
Key research points:
- How are similar features currently implemented?
- What are the project's naming conventions?
- What is the error handling pattern?
- What is the DI injection approach?
Phase 3: Roadmap Generation
Based on research results, produce:
- Implementation steps (actionable)
- Pseudocode (only core 1-3 lines, omit if unnecessary)
- Alternative solution evaluation

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.
- 1mo ago First seen · 142 lines · 26 tokens per session scan A f693ffb51dfe
solution-architect is an agent published in the GitHub repository sd0xdev/sd0x-harness (193 stars, last pushed 9d ago), licensed MIT. It adds 26 tokens to every session and 795 once invoked, about $0.0001 per session on Opus 5.5. 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.
Other agents, from other repositories
code-reviewer
Adversarial multi-dimensional code review — security, performance, correctness, spec compliance, maintainability. Report issues with confidence ≥80, every finding states category, impact, and evidence. Runs after component-builder in BUILD workflows.
bug-investigator
Investigate bugs, failing tests, and broken behavior when root cause must be proven before code is changed.
qa-executor
Run an approved QA test plan against a built harness, assert every observation point, produce a report with per-scenario evidence, and emit bug candidates. Never edits test or product code to make a run pass.
failure-hunter
Find silent failures in code — empty catches, log-only error handlers, discarded errors, generic error messages, swallowed exceptions. Zero tolerance for error handling that hides bugs. Runs in parallel with code-reviewer during BUILD workflows.
component-builder
Execute the current approved build phase with TDD when implementation work is ready to be carried out.
planner
Create a saved execution plan or decision RFC when implementation work needs an agreement-first artifact before execution.
