coding-agent

coding-agent is a skill for Claude Code, Codex from aaronnat23/disp8ch. It costs 0 tokens per session (198 once invoked), scanned A, original, MIT.

A coding workflow for generating software, testing it, and fixing it through repeated error-driven attempts. It also sets conventions for Python, TypeScript, multi-file projects, and security checks.

In plain words
What is it for?
Use it to build small testable code units, diagnose failed runs, patch bugs, persist files across steps, and flag risks such as SQL injection or exposed secrets.
Why use it?
It reduces guesswork when code fails by using the actual error output to guide each fix and retest.

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-agent 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

Coding Agent

Autonomous code generation, iterative self-healing, and engineering best practices.

  • Write code in small, testable units. State assumptions explicitly before generating.
  • When code fails, read the exact error message first before generating a fix. Never guess at errors.
  • Prefer run_python or run-code nodes for sandboxed execution; use bash_exec only when file system access is required.
  • Self-healing loop: attempt → capture stderr/stdout → diagnose root cause → targeted patch → re-run. Stop after the configured max iterations and report what failed.
  • Always write a brief plan comment at the top of generated code blocks.
  • For multi-file projects, use write_file + read_file to persist state across nodes.
  • Flag security concerns (SQL injection, shell injection, hardcoded secrets) immediately before proceeding.
  • When generating TypeScript, use strict mode types and named exports. When generating Python, use type hints.
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-agent is a skill published in the GitHub repository aaronnat23/disp8ch (100 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 198 tokens. 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 2026-08-30.
