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 | $0.00233 | $0.03520 |
| Opus 5 | $0.00117 | $0.01760 |
| Sonnet 5 | $0.00047 | $0.00704 |
| Haiku 4.5 | $0.00023 | $0.00352 |
Grade A, and why
bf-ui 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 2d 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 — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.
specclaw bf-ui
First, run specclaw-ensure-init .specclaw — idempotently creates .specclaw/ if it doesn't exist (silent if already initialized; auto-inits using the current directory's basename as the project name).
Extract, capture, and review the UI-fidelity dimension of a rebuild. Read-only side-command — no specclaw-validate-change call, no <change> gate, matching the analyze/architecture/domain/clarify/baseline/rebuild-plan pattern.
This command is optional and never required. The whole brownfield pipeline works without it. /specclaw:bf-clarify asks the UI fidelity policy question (SQ-013) whether or not this command was ever run, and /specclaw:bf-rebuild-plan only requires UI grounding when that policy is decided FAITHFUL or THEME-ONLY. A project on REINTERPRET answers one question and is done.
UI is never a golden-master seam. templates/seams.md's ## Excluded: UI Automation class stands unchanged, and /specclaw:bf-replay is untouched by this command except for one informational footer line. Nothing this command produces is replayable, diffable, or a proof of pixel-identity — visual fidelity is established by a human reviewing recorded evidence (Mode C's ui-review.md), and this command must never be described as doing more than that.
Determine the mode from the user's message:
| If the message contains | Mode |
|---|---|
--record |
Mode B — record the human's captures |
--checklist <change-name> |
Mode C — generate the review table (run in the NEW repo) |
| neither | Mode A — design/extract (default) |
Mode A — design / extract (default: no flag)
Run this in the legacy repo, after /specclaw:bf-domain (its domain-model.md and functional-spec.md are what the widget cross-reference keys against) and before /specclaw:bf-clarify (so any pending question this run raises is ingested in the same clarify sweep).
- Collect:
specclaw-bf-ui collect .specclaw [path][path]defaults to the repository root when omitted. This parses the priorui-inventory.md/design-tokens.jsonfor their permanentSCR-###/TK-###assignments before archiving all three prior Mode A outputs into.specclaw/ui/archive/, then emits one JSON object: resolved paths, those prior id assignments, the next free ids, which analysis documents are present, the legacy repo's HEAD sha, and a stack-agnostic extension histogram of every file in scope. If it exits non-zero, surface its stderr message to the user verbatim and stop — don't retry, don't guess a different path.
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-ui is a skill published in the GitHub repository chan4lk/specclaw (12 stars, last pushed 3d ago), licensed MIT. It adds 233 tokens to every session and 3,520 once invoked, about $0.0012 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 2026-09-05.
