What it does

Ct Status Diff is an agent skill from agentii-ai/agentii-investment-intelligence. Weekly clinical-trial status diff — the 11-category change report over the stored weekly snapshots (spec 055 FR-B03). Surfaces exactly what changed on the trial registry for your coverage: New / Suspended / Withdrawn / Terminated / Recruiting / Recruitment-Complete / Completed / Ahead / Delayed / Upsized / Downsized, every row carrying previous and new values, with risk flags on Terminated and Downsized and re-timing flags on Ahead and Delayed. The stored-previous-value discipline makes each week's diff…

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/knowledge-frameworks.md` and `references/modes.md`).

It sits in Business, Finance & HR, covering Recruiting and HR and Clinical and healthcare research. The repository describes itself as: Claude-type skills for institutional equity research — 25 AI agent skills with SEC filings, XBRL financials, earnings calendars, DCF/comps/LBO models, and PPT generation. Powered… The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Recruiting and HR
  • Tasks that involve Clinical and healthcare research

Example prompts

  • “/ct-status-diff”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. get_ct_status_changes — the stored-weekly-snapshot diff (pipeline.ct_status_snapshot).
  2. Trial context: search_clinical_trials / get_clinical_trial for design and endpoints.
  3. Company context: search_companies / get_company_profile.
  4. Historical grounding: search_investment_cases (event_type=termination/delay/safety) + search_by_analogue.
  5. Knowledge: search_knowledge_entries for trial-judgment patterns.

What it can do on your machine

Read from SKILL.md and the folder at commit 86980e1. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Ct Status Diff loads about 1.8k tokens when it runs, and up to ~2.5k if it reads all its reference files. Until then it costs about 134 tokens; SKILL.md has 688 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~134
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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.

Data Source Priority

  1. get_ct_status_changes — the stored-weekly-snapshot diff (pipeline.ct_status_snapshot).
  2. Trial context: search_clinical_trials / get_clinical_trial for design and endpoints.
  3. Company context: search_companies / get_company_profile.
  4. Historical grounding: search_investment_cases (event_type=termination/delay/safety) + search_by_analogue.
  5. Knowledge: search_knowledge_entries for trial-judgment patterns.

Methodology

Retrieval Scope

structured_only

Retrieval Strategy
  1. Pull the weekly diff via get_ct_status_changes (ticker-filtered for single names, sector-wide for watchlists).
  2. Rank rows: risk signals first, then re-timing, then recruiting/completed, then new.
  3. For each risk-signal row, pull the trial's design via get_clinical_trial and state what changed and what it implies.
  4. Ground termination/delay reads in search_investment_cases / search_by_analogue (sectors=med); cite /v/ records.
  5. Attach the gap-window statement verbatim wherever the tool reports one.

Temporal Scope

See frontmatter temporal_scope block. Historical diff series (month-over-month) available on request.

Tool Allowlist

See frontmatter allowed_tools.

Protocol
  1. Snapshot-diff pull
  2. Risk/re-timing triage
  3. Per-signal trial context
  4. Historical grounding
  5. Weekly change report + watch flags

Modes

  • Watchlist (default): one diff report across the basket, sorted risk-first.
  • Single ticker: per-trial change ledger with trial context.
  • Signal scan: restrict to risk signals (Terminated/Downsized) or re-timing (Ahead/Delayed).

Tool Fallbacks

FailureFallback
get_ct_status_changes empty (<2 snapshots)State the coverage gap: the diff needs two consecutive snapshot cycles; use search_clinical_trials metadata as a degraded view
Trial not in snapshotsFlag as registry-coverage gap; do not fabricate a previous value
Knowledge tools emptyProceed with structured diff only; annotate knowledge coverage_gap

Output File

{ticker}/{YYYY-MM-DD_HHMM}_ct-status-diff_{affix}.md (watchlist: watchlist/{YYYY-MM-DD_HHMM}_ct-status-diff_{affix}.md)

Output Structure

  1. Executive Summary — the week in trial-registry changes, 2-3 sentences
  2. Risk Signals — Terminated / Downsized rows with previous/new values and trial context
  3. Re-Timing Alerts — Ahead / Delayed rows with date deltas
  4. Flow Changes — New / Recruiting / Recruitment-Complete / Completed / Suspended / Withdrawn rows
  5. Gap Statement — snapshot windows with missing weeks stated
  6. Watch Flags — what to re-check before the next readout
  7. Coverage Gaps — missing snapshots, unregistered trials, degraded modes

Error Handling

ErrorFallback
Fewer than 2 snapshotscoverage_gap with the two-cycle requirement; degraded metadata view only
Empty diffState it plainly — a clean week is a valid result; never pad
Ticker not in med universeResolve via company match; surface the classification gap
