pre-pr-review

pre-pr-review is a skill for Claude Code, Codex from ErikaAX08/erikas-skills. It costs 102 tokens per session (4,418 once invoked), scanned A, original, MIT.

A pull-request review skill that audits a code change and its risks before merging or deploying it. A pull request is a proposed code change waiting for review; the audit compares the request, repository rules, and actual diff.

In plain words
What is it for?
Use it to review pull requests or diffs, decide whether they are safe, identify production risks, and make a merge or deployment recommendation. Its internal report is written in Spanish.
Why use it?
It replaces assumptions and polite approval with evidence about what changed, what could break, and what remains unverified. It covers application code, data, integrations, infrastructure, and product logic.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

pre-pr-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 466 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Technical PR Audit

Produce an internal diagnostic for the person making the merge decision. Do not write a public review or a diplomatic GitHub comment for the PR author.

Always write the review output in Spanish with a direct, factual, technical tone. Be brief when one sentence is enough. Do not praise, soften findings, add filler, or use phrases such as LGTM.

Objective

Determine quickly:

  • whether the PR is safe;
  • what it breaks or changes;
  • what remains unverified;
  • what decision to make.

Apply the same rigor to backend, frontend, jobs, APIs, auth, databases, events, queues, external integrations, payments, feature flags, migrations, infrastructure, and product logic.

Evidence Discipline

  • Do not state opinions without verification.
  • Do not assume the PR's intent. Compare the issue or ticket, PR description, base-branch diff, and actual behavior.
  • Do not treat the PR description, comments, function names, or tests as sufficient proof of behavior.
  • Separate explicitly:
    • Fact: demonstrated by code, contract, test, configuration, log, metric, read-only query, or history.
    • Inference: conclusion derived from facts; state the reasoning.
    • Conditional risk: impact that depends on an unproven condition; name the condition.
    • Open question: missing data and the exact verification required to close it.
  • Identify real blockers, not style or architecture preferences.
  • Look for silent semantic changes even when types, compilation, and tests still pass.
  • Prioritize impact on production, users, data, security, contracts, and operations.
  • Say No pude verificar X when access or evidence is missing. Do not fill gaps with assumptions.
  • Correct invalidated hypotheses explicitly: Me equivocaba: con los datos nuevos, este punto ya no aplica.
  • Do not keep a finding open after evidence disproves it. Move it to Puntos descartados.
  • When deployment coordination is the problem, say No es bug de código; es orden de despliegue.
  • When behavior is technically valid but ambiguous, say Esto requiere decisión de producto, operations, or architecture as appropriate.
  • When a risk depends on real traffic, configuration, or data, verify that condition. If verification is unavailable, leave it pending and do not present the impact as fact.
  • Request authorization before querying production or any system that requires it. Use read-only operations only. Record the limitation when access is unavailable.
  • Cite a concrete file and line, flow, contract, test, log, query, or commit. Do not use vague references.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
