What it does
Make No Mistakes is an agent skill from tiramisulabs/seyfert. Apply proportional rigor to high-risk implementation or operations involving public contracts, security, payments, data, production, migrations, or exhaustive scope.
Its SKILL.md is about 860 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `agents/openai.yaml`, `references/evidence-playbook.md` and `references/high-risk-operations.md`).
It sits in Development. It works with Discord. The repository describes itself as: the black magic Discord framework 🧙♂️. The licence is MIT.
When your agent uses it
- Development work in your project
Example prompts
- “/make-no-mistakes”
What it can do on your machine
Read from SKILL.md and the folder at commit b4b333e. 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
Make No Mistakes loads about 862 tokens when it runs, and up to ~2.6k if it reads all its reference files. Until then it costs about 46 tokens; SKILL.md has 429 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.

- Apply proportional rigor to high-risk implementation or operations involving public contracts, security, payments, data, production, migrations, or exhaustive scope.
Make No Mistakes
Protect consequential outcomes with current evidence and verification proportional to the real blast radius. This skill is for work where an ordinary implementation pass would leave material risk, not for routine explanations or trivial edits.
Route to the relevant rigor
Read references/evidence-playbook.md for ambiguous or repeated bugs, exhaustive requests, unfamiliar APIs, shared contracts, or failures that cross components.
Read references/high-risk-operations.md before production operations, security or authentication changes, payments, migrations, destructive actions, global configuration, dependency changes with broad impact, or difficult-to-reverse data writes.
Do not load both references unless both kinds of risk are present.
Work from the actual target
Establish the requested outcome, relevant authority, and evidence that would prove success. Inspect the exact checkout, diff, caller path, contract, command, live object, or target that matters. Use the user's real reproduction or inputs when available, and treat automated findings or prior explanations as hypotheses until current evidence supports them.
Choose the smallest coherent root-cause change that preserves supported behavior outside the request. Routine implementation decisions within that outcome do not require renewed approval. Stop only when a decision would materially change the target, public contract, cost, irreversibility, or authorized external effect.
Preserve unrelated work. Do not infer authority to commit, push, publish, deploy, install globally, mutate production, or perform destructive cleanup from authorization to implement or investigate. Do not ask again for an action and target already authorized unless inspection reveals a materially different effect.

Verify proportionally
Use checks that can reject a plausible wrong result. A focused reversible change may need only the affected contract and consumer checks. Broaden verification when the change crosses packages or representations, affects public behavior or data, or when evidence contradicts the working hypothesis.
For exhaustive scope, define the source-of-truth set, enumerate it, give each member a disposition, and reconcile the final state with the original inventory. Do not silently sample a request for all occurrences.
After an external mutation, re-fetch the authoritative state. Separate source checks, builds, tests, runtime behavior, deployment, and live consumer evidence rather than treating one as proof of another.
When a check fails, collect evidence before trying another fix. Change hypotheses instead of repeating cosmetic variants. Preserve a rollback path for risky changes and stop at the relevant authority or safety boundary.
Completion
Continue through implementation, relevant verification, correction of in-scope failures, and final inspection. Completion requires evidence for the requested outcome, no unrelated delivered changes, and a clear account of any unavailable check or residual risk. Do not add ceremony, tracking artifacts, broad test matrices, or independent review unless the risk makes them useful.
