Use when asked to write a complaint letter, complain to a company about a product/service, escalate poor service, or demand a refund/replacement. Produces a structured complaint — the facts, the impact, the specific resolution you want, and a deadline — in a firm, professional tone that's hard to ignore and easy to act on.
Its SKILL.md is about 890 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.
When your agent uses it
- Asked to write a complaint letter
- Complain to a company about a product/service
- Escalate poor service
- Demand a refund/replacement
Example prompts
- “/complaint-letter”
What it can do on your machine
Read from SKILL.md and the folder at commit 1cbf1f0. 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
Complaint Letter loads about 891 tokens when it runs. Until then it costs about 102 tokens; SKILL.md has 444 words of instructions outside code blocks.
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.

- complaint-letter
- description
- Write a firm, effective complaint letter that gets a resolution. Use when asked to write a complaint letter, complain to a company about a product/service, escalate poor service, or demand a refund/replacement. Produces a structured complaint — the facts, the impact, the specific resolution you want, and a deadline — in a firm, professional tone that's hard to ignore and easy to act on.
Complaint Letter Skill
A complaint gets resolved when it's specific, reasonable, and makes the desired action obvious — not when it's angry. This skill writes a letter that lays out the facts, states exactly what you want, and gives a clear deadline, in a firm professional tone that a customer-service team can actually action.
Working from a brief
Given "complain about a flight that was cancelled and they won't refund me", write the full letter anyway — infer the standard facts and a reasonable resolution, and bracket the specifics (dates, order/reference numbers, amounts) to fill in. Never hand back advice instead of the letter.
Required Inputs
Ask for these only if they aren't already provided (else infer and bracket):
- What went wrong — the product/service, what happened, and when (dates, order/reference numbers).
- The impact — how it affected you (cost, time, inconvenience, harm).
- What you've done — prior contact and their response, if any.
- What you want — the specific resolution (refund, replacement, repair, apology) and any deadline.
- Recipient & tone — company/person, and how formal.
Output Format
Complaint Letter
A ready-to-send letter:
- Header — your details, date, recipient, and a clear Re: line with the order/reference number.
- 1. The issue — what you bought/used, when, and exactly what went wrong (facts, dated, specific).
- 2. The impact — the concrete consequence for you.
- 3. Prior attempts — what you've already tried, if anything (shows you've been reasonable).
- 4. What you want — the specific resolution, stated plainly, with a reasonable deadline for response.
- 5. Next step — what you'll do if unresolved (escalate, regulator/ombudsman, review) — stated factually, not as a threat.
- Close — professional sign-off and how to reach you.
Provide a short email version too, and notes on anything to confirm.
Show full SKILL.md (167 more words)Show less
Quality Checks
- The facts are specific and dated, with reference/order numbers where relevant
- The requested resolution is concrete and reasonable — not vague dissatisfaction
- A clear, reasonable deadline for response is included
- Tone is firm and professional, not abusive (abuse gives them a reason to dismiss you)
- The escalation path is stated as a fact, not an empty threat
- Both a formal letter and a short email version are provided
Anti-Patterns
- Do not vent without asking for anything — name the specific resolution you want
- Do not be abusive or sarcastic — it lets the recipient dismiss the complaint
- Do not omit reference numbers and dates — they slow or stall the response
- Do not make threats you won't act on — state real next steps factually
- Do not bury the ask — the resolution and deadline must be impossible to miss
Based On
Consumer-advocacy correspondence practice — factual specificity, a concrete remedy, a reasonable deadline, and a stated escalation path.
Example Trigger Phrases
- "Write a complaint letter."
- "Escalate poor service."
- "Demand a refund/replacement."
