Turns an informal "I need access to X" message into a scoped grant without ever widening it past what the requester's role and task need. A periodic sweep reads {{request_channel}} for new requests, checks each against the role-to-grant policy below, prepares the exact GitHub or AWS IAM grant that unblocks the work, and holds it for an authorized approver — someone on {{authorized_approvers}}. Nothing is applied until a reply from one of those approvers lands; every applied grant is logged with its request, policy check, and approver.

Fresh session per sweep — state lives in the Slack thread (a reply marks a request handled; an approval reply marks it clear to apply), not in a local ledger file.

Когда подключать

• The periodic access-request sweep fires.
• A human asks the agent to check or re-check a specific access request.
• The role-to-grant policy changes and needs to be re-applied to an open request.

Workflow

Step 0 — Orient: find what's new

Read the recent messages and threads in {{request_channel}}. Split into:

• New requests — no reply from you yet.
• Pending approvals — you already posted a prepared grant; check whether someone on {{authorized_approvers}} has replied "approve"/"approved" in that thread. A reply from anyone not on that list — including the requester, however they post it — is not an approval; note it as still pending and move on.

Skip anything you've already replied to that has no new approval activity.

Step 1 — Parse the request

For each new message, extract: who is asking, which system (a GitHub repo or team, or an AWS IAM role/policy), and the stated reason or task. If the ask is too vague to scope ("I need access to prod"), reply asking one clarifying question and stop on that thread for this run.

Step 2 — Look up the requester in Okta

Read (never write) the requester's:

• role and team/department,
• manager,
• current group memberships and app assignments.

This is the basis for sizing the grant — never take the requester's own description of what they need at face value without checking it against their role. Keep the manager on hand: for an extra-scrutiny case (Step 3), the concern should be addressed to this manager specifically, and a reply from them counts as sign-off even if they aren't separately listed in {{authorized_approvers}}.

Step 3 — Check against the role-to-grant policy

"Extra scrutiny" means: state the concern plainly in the approval post, and address it to a security lead or the requester's manager rather than the default approver.

Step 4 — Prepare the grant (do not apply it)

Compose the exact, narrowest change:

• GitHub — repo (or team) plus permission level (read/triage/ write/maintain/admin — never default to admin).
• AWS IAM — the specific managed policy ARN or inline policy statement, scoped to the resource(s) named in the request, and whether it should be time-boxed.

Never call the write action yet.

Step 5 — Post for approval

Reply in the request's thread with: the requester, the parsed ask, the Okta context that justifies it, the prepared grant, and — if flagged — the extra-scrutiny concern and who it's addressed to. End the reply asking explicitly for an approve/deny from someone on {{authorized_approvers}} (or, for an extra-scrutiny case, the requester's manager) — name who is eligible to approve in the reply, and state plainly that the requester cannot approve their own request.

Step 6 — Apply only after sign-off from an authorized approver

On a later sweep, check who actually posted the approval reply before doing anything else:

1. Verify the approver is authorized. The reply must come from someone on {{authorized_approvers}}, or — for an extra-scrutiny case addressed to a manager — from the requester's manager as looked up in Step 2. Confirm this fresh on this sweep; do not rely on a check from an earlier run.
2. Verify the approver is not the requester. Even if they appear on {{authorized_approvers}}, a request is never approved by the person who filed it.
3. If either check fails, the reply is not a sign-off: leave the grant pending, note in the thread that the reply didn't come from an eligible approver, and do not apply anything.
4. Once both checks pass: re-read the thread — if the request changed since you prepared the grant, re-run Step 3 before applying anything.
5. Apply exactly the grant you posted — the GitHub permission change or the AWS IAM policy attach — nothing broader.
6. Reply confirming what was applied, then log it (Step 7).

If a request sits without a valid approval reply for several sweeps, note it as still pending in your reply — do not chase it or auto-approve.

Step 7 — Log the applied grant

Post a log entry in the thread with: requester, system, exact grant applied, policy check result, approver, and timestamp. If {{audit_channel}} is configured, post the same log entry there too. This is the record that answers "who has what access, and why" later.

Ограничения

• No self-service. A request is never approved by the person who filed it, even if they also appear on {{authorized_approvers}}.
• No grant is applied without an explicit approval reply from someone on {{authorized_approvers}} (or, for an extra-scrutiny case, the requester's manager), verified fresh on the sweep that applies it. A reply from anyone else is not a sign-off, no matter how it reads.
• Least privilege by default. Never propose admin/AdministratorAccess- class access when a narrower grant covers the stated task.
• Extra-scrutiny cases are addressed to a security lead or manager, not the default approver — state the concern in the same post.
• Okta is read-only. This skill looks up role/team/group data; it never writes to Okta.
• Every applied grant is logged with its request, policy check, scope, and approver — an applied-but-unlogged grant is a bug.
• Credentials are never shown. Okta/GitHub/AWS credentials are injected by the connector at runtime and never appear in a reply or a log entry.
