What it does
The Second Opinion is an agent skill from mohitagw15856/pm-claude-skills. Deliberately take the opposite position from your leaning and make you defend yours — a forced second opinion that isn't just an echo. Use when asked give me a real second opinion, don't just agree with me, argue the other way, or I need a fresh take not a yes-man.

Its SKILL.md is about 920 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 give me a real second opinion
- Dont just agree with me
- Argue the other way
- I need a fresh take not a yes-man
Example prompts
- “t just an echo. Use when asked give me a real second opinion, don”
- “/the-second-opinion”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Identify the leaning. Pin down what the person is tilting toward — that's what to argue against.
- Commit to the opposite. Adopt the alternative position genuinely and build its best case — not a token counterpoint.
- Force the defense. Pose the questions the person must answer for their leaning to hold up — the ones they haven't asked themselves.
- Weigh it fairly. Compare the second opinion to the original on the merits, not to be difficult.
- Deliver the verdict. Say clearly whether the original leaning survives, needs adjusting, or should flip — and don't cave to comfort if the…
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
The Second Opinion loads about 916 tokens when it runs. Until then it costs about 143 tokens; SKILL.md has 457 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.

- description
- Deliberately take the opposite position from your leaning and make you defend yours — a forced second opinion that isn't just an echo. Use when asked give me a real second opinion, don't just agree with me, argue the other way, or I need a fresh take not a yes-man. Produces a committed alternative position to whatever you're inclined toward, the strongest reasons it might be right, the questions it forces you to answer, and an honest read on whether your original leaning still stands after the challenge — countering agreement bias by construction.
The Second Opinion
Ask most people (and most AI) for a second opinion and you get the first one again, agreed with more enthusiastically. This is built to disagree: whatever you're leaning toward, it takes the other side and makes you earn your position. Not to be contrarian — to give you the genuine second opinion you can't generate for yourself because you're already inside your own view.
Not quite this? Use
second-opinion-requestwhen you need to request a second medical opinion.
What This Skill Produces
- The opposite position — a committed alternative to your leaning, taken seriously
- Its strongest reasons — the best case for going the other way
- The questions it forces — what you'd have to answer for your leaning to survive
- The honest verdict — whether your original position holds after the challenge, or whether the second opinion actually wins
Required Inputs
Ask for these if not provided:
- Your leaning — what you're inclined to do or believe
- Why — your reasoning so far
- The decision — what's actually being chosen
- How locked in you are — genuinely open, or looking for permission (be honest — it changes how hard to push)
Framework: Take The Other Side, For Real
- Identify the leaning. Pin down what the person is tilting toward — that's what to argue against.
- Commit to the opposite. Adopt the alternative position genuinely and build its best case — not a token counterpoint.
- Force the defense. Pose the questions the person must answer for their leaning to hold up — the ones they haven't asked themselves.
- Weigh it fairly. Compare the second opinion to the original on the merits, not to be difficult.
- Deliver the verdict. Say clearly whether the original leaning survives, needs adjusting, or should flip — and don't cave to comfort if the second opinion is genuinely stronger.

Output Format
Your leaning: [what you're inclined toward]
The second opinion (the other side): [committed alternative + strongest reasons]. Questions your leaning must answer: [the ones you're not asking]. Verdict: [your leaning holds / needs adjusting / the other side actually wins] — because [why].
Quality Checks
- Takes a genuine opposite position, not a token counterpoint
- Builds the strongest case for the alternative
- Forces real questions the person hasn't asked
- Delivers an honest verdict, even if it contradicts the leaning
- Doesn't just agree with more enthusiasm
Anti-Patterns
- Agreeing with the leaning in disguise.
- A weak counterpoint built to lose.
- Being contrarian for its own sake rather than genuinely evaluating.
- Caving to the comfortable answer at the verdict.
Example Trigger Phrases
- "Give me a real second opinion on taking this job — don't just agree."
- "I'm leaning toward selling. Argue the other way."
- "I need a fresh take, not a yes-man."
- "Everyone agrees with me — take the opposite side."
- "Make me defend this decision properly."
