firecrawl-research-papers skill documents a non-existent --k flag (should be --limit)

[shivss26]

The firecrawl-research-papers skill documents --k <number> for the firecrawl research search-papers and related-papers CLI commands, but the CLI has no --k flag. The result-count flag is --limit. Because the CLI silently ignores unknown options, following the skill literally is a silent no-op — users get the default count (40) instead of the value they pass.

Affected file: skills/firecrawl-research-papers/SKILL.md

Two lines:

• CLI: firecrawl research search-papers <query> [--k <number>]
• CLI: firecrawl research related-papers <seedIds...> --intent <intent> [--mode <similar|citers|references>] [--k <number>]

Actual CLI (firecrawl-cli@1.19.18):

$ firecrawl research search-papers --help
  --limit <number>     Number of results to return (default: 40)
  -k, --api-key <key>  Firecrawl API key (overrides global --api-key)

There is no --k long option — -k is --api-key (a key string, not a count).

Repro — --k is silently ignored:

$ firecrawl research search-papers "test query" --k 3
## [pmid:...] ...    # returns results at the default limit (40), exit 0 — not capped to 3

Suggested fix: replace --k <number> with --limit <number> in both CLI examples. (The MCP signatures ...(query, k?) are a separate surface and may be correct for the MCP tool — only the CLI lines are affected.)
