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.

What 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 5.1 | $0.00031 | $0.00901 |
| Opus 5 | $0.00015 | $0.00451 |
| Sonnet 5 | $0.00006 | $0.00180 |
| Haiku 4.5 | $0.00003 | $0.00090 |
Grade A, and why
architecture-paradigm-modular-monolith 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 9d 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.

The Modular Monolith Paradigm
When To Use
- Organizing large codebases into well-bounded modules
- Teams wanting microservice boundaries without distributed complexity
When NOT To Use
- Already distributed as microservices
- Tiny applications where module boundaries add unnecessary complexity
When to Employ This Paradigm
- When you desire team autonomy similar to that of microservices, but without the operational overhead of a distributed system.
- When release velocity is slowed by tangled dependencies between internal modules.
- When a monolithic architecture is simpler to operate today, but there is a clear need to evolve toward a service-based model in the future.
Adoption Steps
- Identify Modules: Define module boundaries that align with distinct business capabilities or Bounded Contexts from Domain-Driven Design.
- Encapsulate Internals: Use language-level visibility modifiers (e.g., public/private), separate packages, or namespaces to hide the implementation details of each module.
- Expose Public Contracts: Each module should expose its functionality through well-defined facades, APIs, or events. Forbid direct database table access or direct implementation calls between modules.
- Enforce Architectural Fitness: Implement automated tests that fail the build if forbidden dependencies or package references are introduced between modules.
- Plan for Evolution: Continuously track metrics such as change coupling and deployment scope to make informed decisions about if and when to split a module into a separate service.
Key Deliverables
- An Architecture Decision Record (ADR) that maps module boundaries and defines the rules for any shared code.
- Formal contract documentation (e.g., OpenAPI specs, event schemas) for every interaction point between modules.
- Automated dependency checks and dedicated CI/CD jobs for each module to enforce boundaries.
Risks & Mitigations
- Regression to a "Big Ball of Mud":
- Mitigation: Without strict enforcement, module boundaries will inevitably erode. Treat any boundary violation as a build-breaking error and maintain a disciplined approach to code reviews.
- Shared Database Hotspots:
- Mitigation: High contention on a shared database can become a bottleneck. Introduce clear schema ownership, use view-based access to restrict data visibility, or implement data replication strategies to reduce coupling.
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.

architecture-paradigm-modular-monolith is a skill published in the GitHub repository athola/claude-night-market (337 stars, last pushed 2d ago), licensed MIT. It adds 31 tokens to every session and 901 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 2026-09-03.
