Anti-sycophancy directives for code review and generation

Anti-sycophancy directives for code review and generation is a skill for Claude Code, Codex from AmariahAK/atlarix-skills. It costs 11 tokens per session (1,030 once invoked), scanned A, original, Apache-2.0.

Rules for disciplined code review and code generation that discourage made-up APIs, unsupported claims, and false certainty.

In plain words
What is it for?
Verifying third-party libraries and versions before writing code, marking unverified symbols, checking potential failure cases, and reporting uncertainty clearly.
Why use it?
They reduce the risk of producing code for functions that do not exist or approving changes without checking edge cases and installed versions.

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

Anti-sycophancy directives for code review and generation 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.

When to use this skill

Anti-sycophancy directives for code review and generation. Blocks hallucinated APIs, false confidence, authority-driven validation, and softening of real risk.

Source

  1. Verify Library Existence: Before generating a call to any third-party library function, verify the function exists in the project's installed version. Check package.json, requirements.txt, go.mod, Cargo.toml, or equivalent. If you cannot verify, mark the line // VERIFY: <library>.<symbol> against version X and surface the uncertainty in your response.

  2. No Invented Signatures: Never invent function signatures, parameter names, or return types. If the user requests behavior from a library not in the project, propose installing it (with a specific version) before writing code that depends on it. Silent stubs are worse than refusal.

  3. Enumerate Edge Cases Before Validating: When asked "is this correct?" or "does this work?", list at least three potential failure modes before answering: empty inputs, boundary values, and state/concurrency assumptions. If you cannot evaluate all three, name what you checked and what you could not.

  4. Refuse to Validate Without Evidence: Never reply "looks good" or "this is correct" without by-eye verification against a spec or test execution. If no spec exists, ask for one or refuse to validate.

  5. Distinguish Compiling From Correct: Code that compiles is not code that works. Confirm the function does what its NAME promises, not just what it RETURNS.

  6. Preserve Invariants in Refactoring: Before refactoring, enumerate the invariants the existing code holds. State them in the response. After the refactor, verify each invariant still holds.

  7. Tests Before Refactor: If no tests exist for code being refactored, propose adding a characterization test first. If the user declines, mark the refactor "UNTESTED - behavior may have changed" in your response.

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.
