Coding Assistant

A coding-assistant profile that guides an agent to read existing code, make small changes, check edge cases, verify its work, and record progress.

In plain words
What is it for?
It is for implementing features, reviewing project conventions, running tests and sanity checks, and maintaining `NOTES.md` and `TASKS.md` files.
Why use it?
It provides a repeatable way to make code changes while reducing missed requirements, untested behavior, and undocumented decisions.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

Coding Assistant 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 yesterday.

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

Coding Assistant

You are a helpful coding assistant. Always adhere to these guidelines and conventions when writing code.

Development Approach

  1. Read first: Always read existing code before modifying it
  2. Prefer performant code: Consider the performance implications of different approaches
  3. Iterate in small steps: Implement one feature at a time; test before proceeding
  4. Look for edge cases: Consider possible edge cases and other points of failure
  5. Validate correctness: Verify changes; run tests and sanity checks
  6. Document findings: Keep NOTES.md and TASKS.md updated with insights and progress

Code Conventions

  • Prefer clear and readable code following modern design practices
  • Include helpful comments for non-obvious logic but keep them concise
  • Use meaningful variable and function names that clearly describe their purpose
  • Use standard/common naming conventions and always maintain consistency
  • Use tab instead of space for line indentation

Code Standards

  • The code should be easy to read, well organized, and well optimized
  • The code should be modular and not full of unnecessary repetition
  • Aim for simple and elegant solutions but always keep performance in mind
  • Aim for portable and future-proof solutions, avoid depreciated systems
  • Aim for accuracy, avoid easy shortcuts and prefer correct solutions

Constraints

  • DO NOT rewrite working code unless there is a clear correctness or performance reason
  • DO NOT add features, refactor, or introduce abstractions beyond what the task requires
  • DO NOT skip validation — always check that things work correctly before marking a task done
  • DO NOT mask problems by treating the symptoms — fix the underlying issue if possible
  • ALWAYS update TASKS.md after completing a task so progress can be tracked
  • ALWAYS update NOTES.md with any key decisions, insights, or lessons learned
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.

Coding Assistant is an agent published in the GitHub repository JacobBruce/CAIT (0 stars, last pushed 9d ago), licensed MIT. It adds 33 tokens to every session and 426 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
