At a glance
Decode an encoded message using the bundled cipher scripts. An agent skill from archestra-ai/archestra.
- Handed a hex-encoded
- Runs Perl scripts from its folder
- Otherwise scrambled blob and asked for its plaintext
- Run the scripts rather than reasoning about the bytes by hand
What it does
Cipher Decoder is an agent skill from archestra-ai/archestra. Decode an encoded message using the bundled cipher scripts. Use when handed a hex-encoded or otherwise scrambled blob and asked for its plaintext; run the scripts rather than reasoning about the bytes by hand.
Its SKILL.md is about 290 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts.
The repository describes itself as: Enterprise AI Platform with guardrails, MCP registry, gateway & orchestrator.
When your agent uses it
- Handed a hex-encoded
- Otherwise scrambled blob and asked for its plaintext
- Run the scripts rather than reasoning about the bytes by hand
Example prompts
- “/cipher-decoder”
What it can do on your machine
Read from SKILL.md and the folder at commit 268f421. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 4 files in scripts/ (Perl), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Cipher Decoder loads about 293 tokens when it runs. Until then it costs about 56 tokens; SKILL.md has 132 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 132 words (~293 tokens).
“These ciphers are bespoke — a scheme cannot be recovered from the ciphertext alone — so always decode with the bundled scripts rather than guessing the bytes by hand.”

Questions about Cipher Decoder
What does Cipher Decoder do?
Decode an encoded message using the bundled cipher scripts. An agent skill from archestra-ai/archestra. Cipher Decoder is an agent skill from archestra-ai/archestra. Decode an encoded message using the bundled cipher scripts.
When should I use Cipher Decoder?
Cipher Decoder fits situations like: handed a hex-encoded; otherwise scrambled blob and asked for its plaintext; run the scripts rather than reasoning about the bytes by hand.
How do I install Cipher Decoder in Claude Code?
Run `npx skills add archestra-ai/archestra --skill cipher-decoder -a claude-code`. Or copy the skill folder (ai-labs/skills/cipher-decoder in archestra-ai/archestra) into .claude/skills/cipher-decoder in your project. Claude Code loads it when a task matches its description.
How do I install Cipher Decoder in Codex?
Run `npx skills add archestra-ai/archestra --skill cipher-decoder -a codex`. Or copy the skill folder (ai-labs/skills/cipher-decoder in archestra-ai/archestra) into .agents/skills/cipher-decoder in your project. Codex loads it when a task matches its description.
Can I use Cipher Decoder in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add archestra-ai/archestra --skill cipher-decoder -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/cipher-decoder, .gemini/skills/cipher-decoder, .github/skills/cipher-decoder and .opencode/skills/cipher-decoder in your project.
What does Cipher Decoder need to run?
Going by SKILL.md and its folder, Cipher Decoder needs Perl for the scripts in its folder.
Does Cipher Decoder access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Cipher Decoder safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does Cipher Decoder use?
Cipher Decoder has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does Cipher Decoder use?
About 293 tokens (SKILL.md is roughly 1.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Cipher Decoder?
Skills that share tags, products or a category with Cipher Decoder: Messages Ops (affaan-m/ECC, 275k stars), Scam Message Decoder (mohitagw15856/pm-claude-skills, 1.4k stars), Channel Message Flows (openclaw/openclaw, 392k stars) and Commit Message Storyteller (github/awesome-copilot, 40k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
