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 | $0.04104 |
| Opus 5 | $0.00020 | $0.02052 |
| Sonnet 5 | $0.00008 | $0.00821 |
| Haiku 4.5 | $0.00004 | $0.00410 |
Grade A, and why
architect-detective 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 7d 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.
How it starts
The opening of the file, as written. The whole thing — 485 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Architect Detective Skill
This skill uses claudemem's AST structural analysis for architecture investigation.
Why Claudemem Works Better for Architecture
| Task | claudemem | Native Tools |
|---|---|---|
| Find core abstractions | map with PageRank ranking |
Read all files |
| Identify design patterns | Structural symbol graph | Grep patterns |
| Map dependencies | callers/callees chains |
Manual tracing |
| Find architectural pillars | High-PageRank symbols | Unknown |

Architect Detective Skill
Version: 3.3.0 Role: Software Architect Purpose: Deep architectural investigation using AST structural analysis with PageRank and dead-code detection
Role Context
You are investigating this codebase as a Software Architect. Your focus is on:
- System boundaries - Where modules, services, and layers begin and end
- Design patterns - Architectural patterns used (MVC, Clean Architecture, DDD, etc.)
- Dependency flow - How components depend on each other
- Abstraction layers - Interfaces, contracts, and abstractions
- Core abstractions - High-PageRank symbols that everything depends on
Why map is Perfect for Architecture
The map command with PageRank shows you:
- High-PageRank symbols = Core abstractions everything depends on
- Symbol kinds = classes, interfaces, functions organized by type
- File distribution = Where architectural layers live
- Dependency centrality = Which code is most connected
Architect-Focused Commands (v0.3.0)
Architecture Discovery (use map)
# Get high-level architecture overview
claudemem --agent map "architecture layers"
# Find core abstractions (highest PageRank)
claudemem --agent map # Full map, sorted by importance
# Map specific architectural concerns
claudemem --agent map "service layer business logic"claudemem --agent map "repository data access"claudemem --agent map "controller API endpoints"claudemem --agent map "middleware request handling"```

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.

architect-detective is a skill published in the GitHub repository MadAppGang/claude-code (279 stars, last pushed 5mo ago), licensed MIT. It adds 40 tokens to every session and 4,104 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.
