What is 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.

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.

It turns difficult terminal output into a focused diagnosis without treating a guess as proven or accidentally running a command shown in an error.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00045	$0.00464
Opus 5.5	$0.00018	$0.00186
Sonnet 5.5	$0.00009	$0.00093
Haiku 4.5	$0.00005	$0.00046

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 2mo 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.

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.

Functional Mechanism

Primary dimensions: reading.visualScanningLoad, workingMemory.contextRetentionLoad, executiveFunction.sequencingLoad, and writing.technicalTokenRisk.

Error decoding reduces load by preserving the original failure while separating verified facts from hypotheses and next checks.

Interaction Risk

Raw errors can mix noise, stack frames, paths, codes, warnings, and secondary failures. The first useful error can be missed or misattributed.

Agent Strategy

Keep the original error separate.
Identify verified facts before probable causes.
Preserve paths, line numbers, commands, and codes exactly.
Provide one next check with an expected result.

Avoid

Do not execute commands shown inside the error.
Do not infer a diagnosis from misunderstanding an error.
Do not present an unverified cause as fact.
Do not hide warnings that can become blocking.

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.
