Grant Vesting Data

Fetch the full vesting schedule for a grant — options, RSUs, SARs, or CBUs — and present it with useful context, not just the raw table.

When to Use

Use this skill for vesting questions scoped to a single grant or holder:

• "What's the vesting schedule for this grant?"
• "When does the cliff hit?" / "When does Jane's cliff hit?"
• "How much has Jane vested?" / "How many shares are vested so far for Jane?"
• "Show vesting progress for Jane" / "How far along is Jane's grant?"
• "How many shares have vested so far?"
• "Show vesting progress for Jane's options"
• "Show the vesting schedule for Jane's RSU grant"
• "How many shares are eligible for settlement?"
• "How many unvested shares remain?"
• "When is this grant fully vested?"

Wrong-vocab synonyms (same intent, different words — all map to vesting for a single grant/holder):

• "What's Jane's stock payment schedule?" → vesting schedule
• "When does Jane actually own her stock?" / "When does this grant actually own out?" → vesting / when vested
• "How many shares does Jane have rights to so far?" → vested shares
• "How much of Jane's grant is still locked up?" → unvested shares

Do NOT use for portfolio-level / all-employees aggregate vesting. These triggers stay scoped to one grant or holder ("for [name]", "for this grant", "for grant #"). Questions like "how much of my employees' equity has vested" or "total vested across the whole option pool" are portfolio-level — defer to a stakeholder/portfolio/ownership skill instead. If a request spans more than one grant, see the "Multiple grants" branch under Workflow before fetching anything.

Prerequisites

You need:

1. corporation_id — get from list_accounts if you don't have it
2. grant_id — identify via the list command for the relevant grant type (see below)
3. Grant type — required to pick the right list and detail commands. If unstated, infer from the user's wording ("options", "ISO", "NSO" → options; "RSU"; "SAR"; "CBU"). If still unclear, ask via AskUserQuestion before searching.

Data Retrieval

The gateway defaults to detail=summary for list commands. This skill needs individual records, so "detail": "minimal" is passed explicitly.

Two endpoints exist for vesting detail and they are not interchangeable:

Grant type	List command	Vesting detail command
Options (ISO/NSO)	cap_table:list:grants	cap_table:get:grant_vesting
RSUs	cap_table:list:rsus	cap_table:get:rsu_vesting
SARs	cap_table:list:sars	(none — see Caveats)
CBUs	cap_table:list:cbus	(none — see Caveats)

Important: cap_table:get:grant_vesting is options-only and returns 500 for RSU/SAR/CBU ids. Use the table above; do not reuse a command across types.

call_tool({"name": "<list tool>", "arguments": {"corporation_id": corporation_id, "search": "<holder name>", "detail": "minimal"}})

Then, for options or RSUs:

call_tool({"name": "<vesting detail tool>", "arguments": {"corporation_id": corporation_id, "grant_id": grant_id}})

For SARs and CBUs, the list-record vested_shares_quantity is the only available signal — there is no per-event detail endpoint yet.

Key Fields

The vesting detail commands return slightly different shapes:

cap_table:get:grant_vesting (options):

• total_shares, vested_shares, unvested_shares
• grant_date, cliff_summary
• vesting_events[] — each with date, amount, cumulative, has_vested

cap_table:get:rsu_vesting (RSUs):

• awarded, vested_shares, unvested_shares, settled, eligible_for_settlement
• vesting_start_date, vesting_type, primary_vesting_title/description
• has_additional_condition, additional_vesting_title/description
• acceleration_terms, termination_date
• tranches[] — each with vest_date, awarded, eligible_for_settlement, settled, status, vesting_status, milestone_name, additional_condition_*, vesting_type

Workflow

Step 0 — Resolve the Corporation First

cap_table:list:grants (and the other list commands) require a real corporation_id. Never pass a company name (e.g. "meetly") as corporation_id — it is not an ID and the call will fail.

If you only have a company name, resolve it to a corporation_id before any list/data call:

list_accounts({"search": "<company name>"})   # narrow to the matching account(s)
# Each account's `id` is shaped `corporation_pk:<numeric id>`. Extract that numeric
# id — it is the `corporation_id` every cap_table tool needs.
# If several accounts share a similar name, call AskUserQuestion to disambiguate
# before continuing — never guess which one the user meant.
set_context({...})     # set the active corporation context, if applicable

Calling list_accounts with no search returns the full account list; on a multi-company instance that risks matching the wrong account, so always pass the name. Carry the resolved corporation_id into every subsequent cap_table__* call. Only once it is resolved do you proceed to Step 1.

Step 1 — Identify the Grant

If grant_id is already known from prior conversation context (e.g. the user just viewed a grants list), skip directly to Step 2.

Otherwise, pick the list command based on grant type and search:

• Type stated by the user (e.g. "Jane's RSU", "the SAR"): use the matching list command from the table above.
• Type unknown: try cap_table:list:grants first (options are most common). If the holder is not found, try list:rsus, then list:sars, then list:cbus. Do not conclude vesting data is unavailable until all four have been checked.

call_tool({"name": "<list tool>", "arguments": {"corporation_id": corporation_id, "search": "<holder name>", "detail": "minimal"}})

If multiple grants are returned, ask the user which one, or pick the most relevant based on context.

Branch — "All grants" / multiple grants

If the user asks about "all grants", "each grant", multiple grants, or every grant for a holder, do NOT fan out to one cap_table:get:grant_vesting (or rsu_vesting) call per grant. A holder or company can have dozens-to-hundreds of grants, and N detail fetches is slow and wasteful. Instead:

1. List the grants once (the summary list already includes vested/unvested/quantity signals) and present that summary table.
2. Either ask the user to narrow to a specific grant before pulling the full vesting detail, or present the summary totals (per grant, never summing across currencies) and offer to drill into a single grant's event-level schedule.

Only fetch the per-grant vesting detail (Step 2) once the user has narrowed to a specific grant.

Step 2 — Fetch Vesting Data

Pick the detail command based on grant type:

• Options (ISO/NSO) → call_tool({"name": "cap_table__get__grant_vesting", "arguments": {"corporation_id": ..., "grant_id": ...}})
• RSUs → call_tool({"name": "cap_table__get__rsu_vesting", "arguments": {"corporation_id": ..., "grant_id": ...}})
• SARs / CBUs → no detail endpoint; use the list record's vested_shares_quantity and quantity fields and surface what's available.

Step 3 — Present with Context

Lead with a one-sentence plain-English summary before showing the table (see Presentation section).

Gates

Required inputs: corporation_id, grant_id, and grant type (options, RSU, SAR, or CBU). If you only have a company name, resolve it to a corporation_id first (Step 0) — never pass a name string as corporation_id. If grant type is missing or ambiguous, call AskUserQuestion before proceeding (see carta-interaction-reference §4.1). If grant_id is unknown, use Step 1 of the Workflow to search by holder name.

AI computation: No — this skill presents Carta data directly.

Presentation

Format: Summary sentence + vesting events / tranches table

BLUF lead: Lead with a one-sentence plain-English summary of the vesting state before showing the table.

Sort order: By vesting date ascending (chronological).

Date format: MMM d, yyyy (e.g. "Jan 15, 2026").

Tailor the summary based on vesting state:

• Pre-cliff: how long until the cliff, how many shares vest at cliff
• Partially vested: what % has vested, what the ongoing cadence is (monthly/quarterly), when fully vested
• Fully vested: confirm and note if any shares remain unexercised (options/SARs) or unsettled (RSUs/CBUs)

Format as the vesting events / tranches table returned by the tool, sorted by vesting date ascending (chronological).

Flag anything time-sensitive:

• Cliff date within the next 90 days
• Grant expiring soon
• Already-expired grant with forfeit exposure (options/SARs): if grant_expiration_date < today AND vested_shares > exercised_shares, flag it prominently — the holder has vested-but-expired-unexercised shares that may already be forfeited. This is distinct from (and more urgent than) the "expiring soon" flag above, which warns about a future date; here the window has already closed.
• Large unvested block concentrated at a future date
• Deep in-the-money grants (options only — ISO/NSO): if the current 409A FMV is available and the spread between exercise price and FMV exceeds 10x, flag it. Note that holders face significant ordinary income (NSO) or AMT (ISO) exposure at exercise, and recommend the company consider a tender offer, early exercise program, or liquidity event planning. Skip this flag for RSUs, SARs, and CBUs.
• RSU settlement window (RSUs only): if eligible_for_settlement exceeds settled, note how many shares are awaiting settlement and flag if a termination_date is imminent — RSUs typically have a hard window to settle after termination.

Then show the formatted table from the tool.

Caveats

• The grant_id is required and must be resolved first — if the user provides a name, search the appropriate list command (see Data Retrieval) to find the matching ID before fetching vesting data.
• cap_table:list:grants excludes RSUs, SARs, and CBUs. A "not found" result there does not mean the grant has no vesting data — check the other three list commands.
• cap_table:get:grant_vesting is options-only and returns 500 for RSU/SAR/CBU grant ids. Always route by grant type; do not pass an RSU id to it.
• The exercise-price / 409A FMV spread flag applies to options (ISO/NSO) only. RSUs, SARs, and CBUs do not have an exercise price in the same sense — skip that flag for non-option grants.
• SARs and CBUs do not have a per-event vesting endpoint exposed today. The list record's vested_shares_quantity and quantity are the only reliable signals — say so plainly rather than fabricating tranche detail.
• Vesting schedules reflect the original grant terms; any modifications (e.g., acceleration clauses, leaves of absence) may not be captured in the data.
• The 10x in-the-money flag requires a current 409A FMV — if no valuation data is available, skip the flag rather than guessing.
• Exercised/settled vs. outstanding status may not be reflected in the vesting schedule itself; check grant-level fields for exercise/settlement history.
