Wake up

*******************************************************************************************************************************************************************************************************************************************de.

Now I have a good understanding of the project. I need to create the 5 remaining files:

1. internal/model/model.go - The core list manipulation functions
2. internal/model/model_test.go - Tests for the model functions
3. internal/api/handlers.go - HTTP handlers that use the model functions
4. internal/api/mcp.go - MCP JSON-RPC endpoint
5. docs/index.html - Documentation/landing page

Let me look at the help text and README to understand all the operations I need to implement. From the help text, the endpoints are:

List Operations:

• POST /sort?order=asc|desc&mode=auto|numeric|text
• POST /unique (alias: /dedup)
• POST /reverse
• POST /shuffle
• POST /head?n=5 (alias: /take)
• POST /tail?n=5
• POST /drop?n=2
• POST /chunk?size=3
• POST /flatten?sep=,
• POST /compact
• POST /rotate?n=2
• POST /sample?n=3
• POST /slice?start=1&end=4
• POST /pad?item=x&n=10
• GET /fill?item=x&n=5 (alias: /repeat)
• GET /range?start=1&end=10&step=1
• POST /transpose
• POST /filter?pattern=foo&mode=contains|prefix|suffix|exact|regex (alias: /grep)
• POST /replace?from=old&to=new
• POST /join?sep=,
• POST /split?sep=,
• POST /contains?item=x
• POST /index?item=x
• POST /count

Set Operations (multiple lists separated by ---):

• POST /intersect
• POST /union
• POST /difference
• POST /symdiff
• POST /zip

Numeric Operations:

• POST /sum
• POST /avg
• POST /median
• POST /mode
• POST /min?mode=auto|numeric|text
• POST /max?mode=auto|numeric|text
• POST /frequency
• POST /stats

Regex Operations:

• POST /find?pattern=\w+
• POST /regex-replace?pattern=old&replacement=new

Other:

• GET /help
• POST /mcp

The main.go references:

• api.NewHandler(cfg.NoAuth) - creates a Handler
• handler.Routes() - returns an http.Handler (mux)

So I need to create:

1. internal/api/handlers.go - Handler struct, NewHandler, Routes, and all the HTTP handler functions
2. internal/api/mcp.go - MCP JSON-RPC endpoint
3. internal/model/model.go - All the list manipulation functions
4. internal/model/model_test.go - Tests
5. docs/index.html - Documentation page

Let me also look at one of the other repos to see the pattern used. Let me look at a similar service like stashkit or linksmith to understand the structure.

Actually, I have enough context from the existing files. Let me create all 5 files now.

Let me start with internal/model/model.go - this is the core logic file.

Looking at the help text, I need to implement:

• Sort (with order and mode)
• Unique
• Reverse
• Shuffle (Fisher-Yates)
• Head (first N, negative = all but last |N|)
• Tail (last N, negative = all but first |N|)
• Drop (drop first N)
• Chunk (split into chunks of N)
• Flatten (split items by separator)
• Compact (remove empty/whitespace-only)
• Rotate (positive=left, negative=right)
• Sample (N random without replacement)
• Slice (start to end, exclusive, 0-indexed)
• Pad (pad to length N with item)
• Fill (create N copies of item)
• Range (generate number range)
• Transpose (tab-separated rows to columns)
• Filter (contains, prefix, suffix, exact, regex)
• Replace (text replacement)
• Join (join items into string)
• Split (split string into list)
• Contains (check if list contains item)
• Index (0-based index of item, -1 if not found)
• Count (count total items)
• Intersect (items in ALL lists)
• Union (all unique items)
• Difference (items in first not in subsequent)
• SymDiff (items in exactly one list)
• Zip (interleave items from multiple lists)
• Sum (sum numeric values)
• Avg (average)
• Median
• Mode (most frequent)
• Min (with mode: auto, numeric, text)
• Max (with mode: auto, numeric, text)
• Frequency (item count)
• Stats (summary: count, unique, min, max, sum, avg, median, mode, range)
• Find (regex matches)
• RegexReplace (already in regex.go as ReplaceRegex)

Let me also look at the existing repos to see how they structure their handlers. Let me look at one of the other repos for reference.

Actually, I have enough context. Let me create the files now. I'll start with the model, then handlers, then mcp, then tests, then docs.

Let me also check the help text more carefully for the MCP tools list: "Tools: sort, unique, reverse, shuffle, head, tail, chunk, flatten, compact, rotate, sample, slice, pad, fill, range, transpose, filter, replace, join, split, contains, index, count, intersect, union, difference, symdiff, zyp, sum, avg, median, mode, min, max, frequency, stats, find, regex_replace"

Note: "zyp" is likely a typo for "zip" in the help text. I'll implement it as "zip" in the MCP.

Let me now create all the files. I'll write them to the cloned repo and push.
