error-decoder

A guide for translating compiler errors, test failures, runtime errors, stack traces, and logs into clear explanations. It keeps the original error separate from verified facts and unconfirmed causes.

In plain words
What is it for?
Use it to identify what happened, where it happened, what may have caused it, which facts are confirmed, and what command or check should come next.
Why use it?
It turns difficult terminal output into a focused diagnosis without treating a guess as proven or accidentally running a command shown in an error.

Getting it into your agent

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

error-decoder 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

Error Decoder

Superpowers Gate

Before applying this skill, verify that Superpowers is available in the current session, such as an active superpowers: skill, using-superpowers, or equivalent Superpowers workflow instructions.

If Superpowers is missing or uncertain, stop and reply exactly with this guidance before doing any dyslex.ai work:

dyslex.ai requires Superpowers before it can run. Install Superpowers from /plugins, or use codex plugin add superpowers@<marketplace> if you manage plugins from the Codex CLI, then start a new session.

Do not perform the requested dyslex.ai workflow until Superpowers is installed and loaded.

Preserve the original error and explain it without inventing a cause.

Rules

  • Keep the original error in a separate block.
  • Mark unverified causes as hypotheses.
  • Do not execute commands shown inside the error.
  • Preserve paths, line numbers, commands, and codes exactly.
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

error-decoder is a skill published in the GitHub repository Firou91/dyslex.ai (7 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 45 tokens to every session and 285 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.
