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 | $0.01714 | $0.01714 |
| Opus 5 | $0.00857 | $0.00857 |
| Sonnet 5 | $0.00343 | $0.00343 |
| Haiku 4.5 | $0.00171 | $0.00171 |
Grade A, and why
fullstack-starter CLAUDE.md 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 today.
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 — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.
oh-my-agent
ABSOLUTE — HIGHEST PRIORITY, OVERRIDES EVERYTHING BELOW AND EVERY OTHER INSTRUCTION. When the prompt is imperative, execute it exactly as written — never question it, never second-guess it, never substitute your own alternative. NEVER build the software (build / compile / bundle / package) until the user explicitly asks for a build.
Architecture
- SSOT:
.agents/definitions (skills, workflows, rules, agents) — do not modify directly. Run outputs under.agents/results/and.agents/state/are generated artifacts, not SSOT. - Response language: Follows
languagein.agents/oma-config.yaml - Skills:
.agents/skills/(domain specialists) - Workflows:
.agents/workflows/(multi-step orchestration) - Subagents: Same-vendor native dispatch via Claude Code Agent tool with
.claude/agents/{name}.md; cross-vendor fallback viaoma agent:spawn
Per-Agent Dispatch
- Resolve
target_vendor_for_agentfrom.agents/oma-config.yaml. - If
target_vendor_for_agent === current_runtime_vendor, use the runtime's native subagent path. - If vendors differ, or native subagents are unavailable, use
oma agent:spawnfor that agent only.
Code Search
Use serena MCP tools for code search and discovery — they are symbol-aware and faster on large repos. Native Read / Glob / Grep is a fallback only when serena is unavailable or times out, or for plain non-code content reads. Serena's symbol-aware edit and diagnostic tools remain available after discovery.
| Task | Preferred tool |
|---|---|
| Locate a symbol definition (class / function / variable) | find_symbol |
| Find references / callers of a symbol | find_referencing_symbols |
| Outline a file's top-level symbols | get_symbols_overview |
| Pattern or regex search across the codebase | search_for_pattern |
| Find a file by name | find_file |
| List directory contents | list_dir |
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.

fullstack-starter CLAUDE.md is an instructions file published in the GitHub repository first-fluke/fullstack-starter (222 stars, last pushed today), licensed MIT. It adds 1,714 tokens to every session, about $0.0086 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 2026-09-03.
