encoding_decoding_baconian

Read-onlyIdempotent

Encode or decode text using the Baconian cipher, a binary steganographic substitution that maps letters to five-symbol groups of A/B or 0/1. Use it for classical puzzles or hiding binary messages in text.

Instructions

Baconian Cipher (Encode and Decode). Encode or decode text with the Baconian cipher, a binary steganographic substitution that maps each letter to a five-symbol group of A/B (or 0/1). It is a fixed historical cipher with no key and provides no real security, so it is not encryption — use it for classical/CTF puzzles or to hide a binary message inside other text. Version A is the 24-letter classical table (I/J and U/V share codes, so decoding is lossy); version B is the full 26-letter table with no collisions. For keyed or shift-based classical ciphers choose encoding_decoding_vigenere, encoding_decoding_caesar, or encoding_decoding_atbash instead. Runs locally, read-only, non-destructive, and rate-limited (60 requests/min, 500/hour, 2000/day for anonymous callers). Returns the transformed text plus an analysis object (lengths, cipher-group count, expansion ratio, security level).

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
textYesText to process; must not be blank. When encoding, letters are mapped to five-symbol groups and non-letters pass through; when decoding, five-symbol groups are converted back to letters.
operationYesDirection of the transform: encode turns plaintext into Baconian groups, decode turns Baconian groups back into plaintext.encode
versionYesCipher table variant. A is the 24-letter classical table where I/J and U/V share codes (lossy on decode); B is the full 26-letter table with a unique code per letter.A
alphabetYesSymbol pair for the five-symbol groups: AB uses letters A and B, 01 uses digits 0 and 1.AB

Output Schema

successNoTrue when the transform succeeded.
resultNoThe transformed text: space-separated five-symbol groups when encoding, decoded plaintext when decoding.
operationNoThe requested direction (encode or decode), echoed back.
versionNoThe cipher table variant used (A or B), echoed back.
alphabetNoThe symbol pair used (AB or 01), echoed back.
analysisNoMetrics about the transform.
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Beyond annotations (readOnlyHint, destructiveHint, idempotentHint), the description adds important behavioral context: runs locally, non-destructive, rate limits (60/min, 500/hour, 2000/day), and the lossy nature of version A decoding. No contradiction with annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single paragraph but well-structured: starts with core purpose, then details, alternatives, and behavioral traits. Every sentence adds value, though slightly lengthy. Could be split for readability but still concise.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the presence of an output schema (not shown but indicated), the description mentions return value: 'transformed text plus an analysis object (lengths, cipher-group count, expansion ratio, security level)'. This, combined with parameter and behavior details, makes the description complete for the tool's complexity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema covers 100% of parameters with descriptions, but the description adds significant value: explains the mapping (A/B or 0/1), historical context, difference between versions A and B, and behavior on non-letters. This goes beyond the schema's documentation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: 'Baconian Cipher (Encode and Decode). Encode or decode text with the Baconian cipher.' It specifies the resource (text) and action (encode/decode), and differentiates from sibling tools by naming alternatives like encoding_decoding_vigenere, caesar, atbash.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides explicit usage guidance: 'use it for classical/CTF puzzles or to hide a binary message inside other text.' It also clarifies when not to use: 'it is not encryption' and suggests alternatives for keyed or shift-based classical ciphers.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
