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 | $0.00091 | $0.01323 |
| Opus 5 | $0.00046 | $0.00661 |
| Sonnet 5 | $0.00018 | $0.00265 |
| Haiku 4.5 | $0.00009 | $0.00132 |
Grade A, and why
bill-debate-trace 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 11d 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 — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/bill-debate-trace
- Identify the bill:
bills_search_bills(query="<name>"). - Find debates per house:
parliament_search_hansard(query=..., filters.house=...). - Get divisions per debate:
parliament_get_debate_divisions(debate_ext_id=...). - For named members only:
parliament_get_debate_contributions(debate_ext_id=..., member_id=...). - Surface a chronological view: bill metadata, debates, divisions, named contributions.
Purpose
Assemble a chronological view of a UK bill's parliamentary journey — its current stage, the debates it generated in each House, any divisions (votes), and (if requested) specific contributions by named peers or MPs. The skill draws on three data sources via uk-legal MCP: the Bills API for metadata and stage, Hansard for debates and contributions, and the Votes/Divisions API for division counts and government-win data.
Workflow
Source discipline: If a
uk-legal MCPtool returns empty or errored (status:empty/not_found/upstream_validation/ etc.), do NOT supplement from training data or web search. Report the empty result to the user with the tool'snext_steps/detailfield surfaced, and ask for clarifying information (different spelling of a name, a date range, the source URL) rather than fabricating a plausible-looking answer. Empty results are HONEST signal — not a failure mode to paper over.
Step 1 — Identify the bill
Call bills_search_bills(query="<name>"). Returns bill records with current_stage,
originating_house, and sponsor. If multiple bills match, list them and ask the
user to confirm the right one before proceeding.
Step 2 — Find the debates
Call parliament_search_hansard(query="<bill short title>"). Because the Hansard
search is capped at four results per query, run it per-house if needed:
parliament_search_hansard(query="<short title>", filters.house="Lords")parliament_search_hansard(query="<short title>", filters.house="Commons")
Collect all debate_ext_id values returned across both queries.
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.

bill-debate-trace is a skill published in the GitHub repository uk-agents/uk-legal-plugins (9 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 91 tokens to every session and 1,323 once invoked, about $0.0005 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 2026-08-31.
