Argus: Skill for Claude Code

.agents/skills/minimal-rigorous-work/SKILL.md

minimal-rigorous-work is a skill for Claude Code, Codex from lbx154/Argus. It costs 32 tokens per session (359 once invoked), scanned A, original, MIT.

A lean, evidence-based working method for implementation, research, documents, planning, reviews, and agent coordination.

In plain words
What is it for?
It guides decisions about code changes, external input, authority, persistence, security, money, citations, and irreversible actions.
Why use it?
It reduces unnecessary changes and repeated work by requiring a clear request, observable evidence, explicit errors, and focused validation.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is lbx154/Argus's own configuration. It tells Claude Code and Codex how to work on Argus itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything Argus configures →

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

minimal-rigorous-work 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 2d 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.

What it actually says

Minimal rigorous work

Solve the current task completely with the shortest clear control path.

  • Start from the requested behavior, the real entry point, and observable evidence. Do not fix a bug that cannot be reproduced on the current commit.
  • Reuse existing contracts and helpers. Do not add unrelated features, refactors, dependencies, roles, layers, configuration, or artifacts.
  • Validate external input, authority, persistence, security, money, citations, and irreversible actions. Trust established internal invariants.
  • Unless a demonstrated requirement needs them, do not add hashes, UUIDs, random identifiers, retries, backoff, fallback chains, duplicate guards, speculative locks, compatibility layers, wrappers, factories, or placeholder interfaces.
  • Keep errors explicit. Do not hide defects behind broad catches, empty results, default values, or success-shaped degradation.
  • Use tokens by reducing uncertainty and repeated context: carry one canonical task contract, inspect unchanged inputs once, act when evidence is sufficient, and run one decisive check per claim. Do not hard-code token caps, truncate required context, or add token-shortening functions.
  • Record a reusable lesson only when reproduced evidence shows it generalizes. Scope the lesson narrowly; do not create ceremonial Skills, Wiki entries, or validation-only turns.
  • Review independently and read-only. Verify the changed user-visible path; broaden checks only when the blast radius is broad.
  • Report BLOCKED or UNTESTED honestly. Stop when the requested outcome is complete.

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.
