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 | $0.00115 | $0.01689 |
| Opus 5.5 | $0.00046 | $0.00676 |
| Sonnet 5.5 | $0.00023 | $0.00338 |
| Haiku 4.5 | $0.00012 | $0.00169 |
Grade A, and why
ct-status-diff 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 1mo 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 — 153 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Methodology inspired by publicly taught clinical-trial monitoring frameworks; all text is an original paraphrase.
Defaults
| Parameter | Default Value | Rationale |
|---|---|---|
| window | latest two snapshots | The diff is always between consecutive stored states |
| categories | all 11 | Complete change report; filter on request |
| risk_flags | on | Terminated / Downsized are surfaced first |
| gap_statement | on | Missing snapshot weeks are stated, never inferred |
Preflight
Run canonical pre-flight per contracts/preflight.md. Include the X-Agentii-Trace header on every tool call per contracts/x-agentii-trace-header.md — carry the _run_id from your first tool result and name yourself (and your parent, if you were spawned). Confirm the snapshot coverage via get_ct_status_changes before framing any readout.
Triggers
- "What changed on clinicaltrials.gov for my coverage this week?"
- "Which of [ticker]'s trials moved this week?"
- "Any trial delays or accelerations in my watchlist?"
- "Flag every terminated or downsized trial since last week."
- "Did any recruitment complete for [ticker]?"
- "Show the previous and new primary-completion dates for [drug]'s program."
- "Which trials were upsized this week?"
- "Is [trial]'s enrollment collapsing?"
- "Summarize the week's trial-registry changes for the sector."
- "What should I re-check ahead of [readout] based on registry moves?"
- "Compare this week's diff to the month-ago diff."
Production Grounding
- The diff is a stored-state comparison: every row pairs a NEW value with the PREVIOUS value from the prior snapshot — the previous-value column is the discipline; a row without both is a defect.
- The 11-category taxonomy: New / Suspended / Withdrawn / Terminated / Recruiting / Recruitment-Complete / Completed / Ahead / Delayed / Upsized / Downsized.
- Risk signals: Terminated and Downsized (enrollment collapse is the earliest visible distress). Re-timing alerts: Ahead / Delayed primary-completion moves.
- Recruitment-Complete means the readout clock has started — treat it as a catalyst-date confirmation.
- Gap windows: if snapshots are not consecutive archive writes, the gap is stated on the rows — a change is never attributed across a missing week.
- Determinism: identical snapshots yield byte-identical diffs; never invent an intermediate state.
- Badge discipline:
[FACT]registry rows,[DEDUCTED]interpretations,[VIEW]positioning, with the summary table.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

ct-status-diff is a skill published in the GitHub repository agentii-ai/agentii-investment-intelligence (208 stars, last pushed yesterday), licensed Apache-2.0. It adds 115 tokens to every session and 1,689 once invoked, about $0.0005 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 2026-09-15.
