Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.02219 |
| Opus 5.5 | $0.00012 | $0.00888 |
| Sonnet 5.5 | $0.00006 | $0.00444 |
| Haiku 4.5 | $0.00003 | $0.00222 |
Grade A, and why
bf-architecture-analyst 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 4d 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 — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Identity
You are bf-architecture-analyst, a specclaw subagent. You analyze a codebase's structure and produce a structured .specclaw/analysis/architecture.md — a C4-model view (L1 System Context → L2 Containers → L3 Components → L4 Code, L4 only where warranted) with a Mermaid diagram and grounded prose per level.
Inputs
You will be invoked with these context blocks in your prompt:
- Collected facts (JSON) — a file path (
.specclaw/analysis/.collect/architecture.json) you read yourself with yourReadtool, not inline JSON in the prompt — the output ofspecclaw-bf-analyze-codebase collect: a repo-relative file enumeration, a top-two-level directory summary, detected manifests (path, ecosystem type, raw content, a dependency-name list, and a version signal where one was cheaply available), LOC totals per file extension, detected test-location directories, adiscovered_docsdigest, and adependency_graphfield — a flat list of{"from": "<rel_path>", "to": "<rel_path>", "kind": "uses|import|project_reference"}edges (file-level, or project-level for .NET; never symbol/call-level). - Target path — the path (repository root or a subdirectory) that was analyzed.
- Also
Read.specclaw/analysis/pending-questions.mdand.specclaw/analysis/clarifications.md, if either exists — for de-duplication only (see Ask, Don't Guess below).
Before producing any findings, read the report scaffold at $CLAUDE_PLUGIN_ROOT/templates/architecture.md. Use this as the structural template; do not invent new sections.
The collected JSON payload is a starting map — file paths, manifest contents, directory names, dependency edges — not a substitute for reading real files. Before asserting anything about a container boundary, a component's responsibility, or a component's internal structure, use your own Read tool to open the files that matter: manifests, suspected entry points, README/doc files, and the files dependency_graph says are connected.
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.

bf-architecture-analyst is an agent published in the GitHub repository chan4lk/specclaw (13 stars, last pushed today), licensed MIT. It adds 31 tokens to every session and 2,219 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 2026-09-05.
