What does this agent skill do?
Write an Upwork proposal
Create a focused proposal grounded in the freelancer's real profile and work history. Optimize for relevance and credibility, not volume or generic persuasion.
Select the account
Call list_accounts and choose an account whose raw role is TALENT or FL_AGENCY. Ask the user when more than one is eligible. Retain org_uid and role for every later call, but refer to the account by name and role_label.
Read the job
- Call
find_jobswith actionget. Its id parameter accepts a numeric job id, a~02…ciphertext, or a full Upwork job URL, so a link the user pasted can be passed through unchanged. - To find candidate jobs first, use
find_jobsactionsearchwhen the user supplies search terms, or actionsmart_searchwhen they want work matched to their own profile. Do not pass profile skills intosmart_search; the recommender already knows the profile. Its default mode isbest_match. Whenever you return those results, say that Most Recent is also available, and switch tomode: most_recentwhen they ask for the newest work. Date filters (days_posted, orfrom_date/to_date) apply only tomost_recent; actionsearchcannot filter by date. Search rows do not includeconnects_cost; read that from actiongetwhen the user opens a specific job. A result withappliedtrue means this freelancer already applied — do not recommend applying again. - Surface the exact title, scope, budget, required skills, client preferences, screening questions, and the Connects cost to apply when the response includes them.
- A job's
client.ratingis the average score other freelancers gave that client after working with them, not the client's rating of freelancers. Surface a low rating when the user is deciding whether to apply, and relay the response'sclient_rating_basisframing rather than inventing your own. - When a search returns no rows, read
empty_reasonand say what it means; do not report that the marketplace is empty. Ifno_personalization, use actionsearchfor the whole marketplace. When there is noempty_reason, say only that nothing matched these criteria; an upstream restriction looks the same, so do not assert either.
Rule out an existing invitation or proposal
Do this before drafting. Upwork rejects a duplicate application upstream, so skipping the check wastes the user's turn and can look like a server fault.
- Call
list_freelancer_proposalsactioninvitations. If the job came through an invitation, respond withmanage_proposalsactionaccept_invitationordecline_invitation. Do not use actioncreate, which is only for an uninvited application. - Call
list_freelancer_proposalsactionlistto check for an existing proposal or contract on the same job. Both list actions apply a default status filter, so set the status explicitly when looking for a specific state. - A proposal status of
Acceptedmeans the proposal was submitted and validated. It does not mean the client accepted the freelancer. Prefer the accompanyingstatus_label, which carries the plain-English meaning, and report that to the user.
Gather real evidence
Use only what the tools return. Never invent clients, praise, metrics, credentials, or results.
- For a
TALENTaccount, useget_profileactiongetfor skills, overview, work history, and profile signals; actionlist_highlightsfor portfolio projects and certificates; and actionconnects_balancefor Connects. Onconnects_balance,balanceis the Connects wallet.product_credits, when present, are spendable only on the named product and are not part of that balance — report them separately. - The own-profile read also returns
promotions(earn-Connects tasks and the active Freelancer Plus offer). Mention them when relevant to applying, and share the offer URL exactly as returned. Ifpromotionscarrieserror, say the lookup failed rather than claiming there is no offer. - If
createis refused because Upwork is not allowing this account to submit proposals, relay that reason and checkidentity_verificationon the profile or dashboard, without assuming it is the cause. Do not retry until the user says it is resolved. - For an
FL_AGENCYaccount, useget_agencyactionget_profilefor agency evidence andget_freelancer_financialsactionconnects_balancefor Connects.get_profileis not available to an agency account. - Use
list_freelancer_proposalsto review prior submitted, offered, or hired proposals as writing examples.
Draft the proposal
- Identify the client's primary outcome and pick the strongest matching evidence. Before drafting, read
client_feedbackfromfind_jobsactionget, oruser.nameon an invitation. When a review or the invitation names the client contact or a project, open by addressing that contact and referencing that project. Never invent a name that no review or invitation states. - Write a concise cover letter. The tool enforces a maximum length and reports it; if the user supplies longer text, ask them to shorten it rather than sending it truncated.
- Open with the job-specific outcome.
- Connect one or two real examples to the requested work.
- Explain a practical approach or concrete first steps.
- Address material risks, constraints, and every screening question separately.
- Close with a useful next step.
- If the job requires another language, provide the proposal in English and in that language.
- Always offer attachments rather than silently skipping the question. For a local file, start an upload in the
proposalscontext for a normal application, or theinvitationcontext when accepting a client invitation. An inline upload returns storedfile_uidvalues directly; a fallback-URL upload must be polled until its status isokand then confirmed withconfirm_attachment_upload. Pass the resultingfile_uidvalues to the proposal. A file can only be attached where it was uploaded; a mismatched context is refused and the file must be uploaded again. For aTALENTaccount, also offer relevant portfolio projects and certificates fromget_profileactionlist_highlights, and pass the chosen ids ascertificate_idsandportfolio_project_ids. Do not calllist_highlightsfor anFL_AGENCYaccount; use the agency profile evidence already returned byget_agencyinstead. - Use the exact bid the user approved, passed as a number for
charged_amount. Never substitute a market rate or infer monetary terms.
Submit
- Summarize the cover letter, screening answers, bid, attachments, and highlights, then get explicit confirmation before the first write-capable call.
- Call
manage_proposalsactioncreate. The job reference must be the numeric job id, not the~02…ciphertext. Actiongetaccepts a ciphertext or a job URL and returns the numeric id to pass here. For an agency, omit the team parameter; if the agency has several teams, the error names them and the user picks one. - Present the returned preview and always call out:
- Connects required and the current balance;
- whether the account can apply at all;
- unmet preferred qualifications, or that the qualification check was unavailable;
- required screening answers;
- competing bids and what other applicants bid, only when the preview supplies them; when it says they are unavailable, relay that and never estimate amounts;
boost.suggested_bid, if present, only with its own note, and never restated as a share of applicants;- whether boosting is available and the Connects balance.
- Let the user decide whether and how much to boost. If boosting is unavailable, do not offer it; relay
boost.reason. Otherwise offer it unlessboost.recommendationisskip, stay within the limits the preview states, and apply only the amount the user approved, passed asboost_connects. Once submitted, the bid cannot be edited or withdrawn through this tool. If confirmation reports that the approved bid no longer takes a paid slot, nothing was submitted: present the new bids to beat and get a new amount approved. - If any content or terms change, call action
createagain with the corrected values. The new preview supersedes the pending one. - Get a separate explicit approval to submit, then call
confirm_previewwith actionconfirm, thetypethe preview returned, and only the returnedpreview_id. A new application and an invitation response return different types, so use whichever came back rather than assuming. - To verify, list the freelancer's proposals with status
Pending. If the user boosted, readlist_freelancer_proposalsactiongetand reportterms.connectsBid— that is the bid Upwork stored, which can differ from the amount that was sent, and it cannot be changed through this tool.
If Connects are insufficient, say so plainly and let the user add Connects, then retry. Do not describe the failure as permanent.
If the server returns a first-time marketplace safety policy prompt, present it to the user. Call manage_proposals action acknowledge_policy only after they explicitly acknowledge it, then retry the interrupted action.
Messaging the client
A freelancer cannot open a proposal room or send the first message on a proposal. To reply to an existing conversation, use list_freelancer_proposals action get_room, or get_messages action find_room with context_type=proposal, then send_message action send. If no room exists yet, tell the user the client must message first. A find_room not-found is final until a conversation starts. A direct contract proposal is only available from a conversation the client started.
Quality rules
- Tailor every proposal to one job. Never reuse a cover letter across jobs.
- Prefer concrete evidence over adjectives and boilerplate.
- Follow the server's presentation rules for titles, identifiers, and untrusted client-authored text.
