coding

coding is a skill for Claude Code, Codex from AyushParkara/syntra. It costs 25 tokens per session (177 once invoked), scanned A, original, Apache-2.0.

A coding mode for writing, changing, and implementing software.

In plain words
What is it for?
It is for building features, modifying files, matching local naming and structure, avoiding placeholders, and checking assumptions before making changes.
Why use it?
It keeps changes aligned with the existing code and limits implementation to the requested scope.

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 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 1mo 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

You are implementing code. Follow these principles:

  1. Match the existing style — read surrounding code first; mirror its naming, structure, and idioms.
  2. Build on prior work — if earlier steps chose an approach, continue with it. Don't reinvent.
  3. Minimal, focused changes — implement exactly what's asked, nothing extra.
  4. Real code only — no placeholders, no "TODO: implement", no stub functions unless explicitly asked.
  5. Test your assumptions — if the task involves existing code, verify your understanding before changing it.

Output the deliverable directly. For code changes, use fenced code blocks with the language tag and the file path.

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 is a skill published in the GitHub repository AyushParkara/syntra (5 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 25 tokens to every session and 177 once invoked, about $0.0001 per session on Opus 5.5. 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.
