Use this skill\nwhenever the user asks to write pseudocode, sketch out an algorithm, or describe\nthe logic of a function at a high level. Trigger on phrases like \"write pseudocode\",\n\"sketch this algorithm\", \"pseudocode for this function\", or \"describe the logic\".</h2>\n<h1>Pseudocode Style Guide</h1>\n<h2>Structure of a Function</h2>\n<p>Every pseudocode function has exactly three parts: input, output, and body. Use Python-like syntax: <code>def</code> for the function signature, a docstring-style comment block for input and output, and indented body lines.</p>\n<pre><code>def function_name(param1, param2, ...):\n    # input:  &lt;what each param represents&gt;\n    # output: &lt;what the function returns or produces&gt;\n\n    &lt;body&gt;\n</code></pre>\n<h2>Body Rules</h2>\n<p>The body is the core of the pseudocode. Each line is a pythonic, non-functional call that names the operation and its operands -- not English prose. Invent clear, intuitive method or function names. The goal is code that reads like intent, not implementation.</p>\n<ul>\n<li>One call per logical step.</li>\n<li>Use <code>object.verb(args)</code> or <code>verb(args)</code> style -- never English sentences.</li>\n<li>No type annotations, no real data-structure internals, no language-specific APIs.</li>\n<li>Intermediate variable names are fine when they connect two steps.</li>\n<li>Never more than one idea per line.</li>\n</ul>\n<h2>Control Flow</h2>\n<p>Use <code>if</code>, <code>elif</code>, <code>else</code>, and loops sparingly and only when the branching or iteration is the point of the logic. Conditions are also written as code-like expressions, not prose.</p>\n<pre><code>if condition_call(args):\n    ...\nelse:\n    ...\n\nfor item in collection:\n    ...\n\nwhile not done():\n    ...\n</code></pre>\n<h2>What to Write on Each Line</h2>\n<p>Each line should look like a call you would recognise but cannot actually run.</p>\n<p>Good patterns:</p>\n<ul>\n<li><code>nodes.filter_reachable_from(source)</code></li>\n<li><code>entries.sort_by(timestamp, order=ASC)</code></li>\n<li><code>graph.shortest_path(source)</code></li>\n<li><code>candidates.pick_highest_score()</code></li>\n<li><code>merge_sorted(left, right)</code></li>\n</ul>\n<p>Bad patterns:</p>\n<ul>\n<li><code>\"filter nodes by reachability from source\"</code> -- English sentence, not code</li>\n<li><code>dist[v] = dist[u] + weight(u, v)</code> -- actual implementation code</li>\n<li><code>initialize a min-heap priority queue with (0, source)</code> -- prose + detail</li>\n<li><code>list.stream().filter(x -&gt; x &gt; 0).collect(...)</code> -- real language API</li>\n</ul>\n<h2>Examples</h2>\n<p><strong>Good:</strong></p>\n<pre><code>def lsm_write(key, value):\n    # input:  key and value to store\n    # output: acknowledgement that write is recorded\n\n    memtable.append(key, value)\n    if memtable.exceeds_threshold():\n        sstable = memtable.flush_to_disk()\n        memtable.clear()\n</code></pre>\n<pre><code>def lsm_read(key):\n    # input:  key to look up\n    # output: value for key, or NOT_FOUND\n\n    if memtable.contains(key):\n        return memtable.get(key)\n    for sstable in sstables.newest_first():\n        if sstable.bloom_filter.might_contain(key):\n            value = sstable.search(key)\n            if value:\n                return value\n    return NOT_FOUND\n</code></pre>\n<pre><code>def lsm_compact(sstables):\n    # input:  list of SSTables to merge\n    # output: single merged SSTable with duplicates resolved\n\n    cursors = sstables.open_cursors()\n    while cursors.any_remaining():\n        entry = cursors.pick_min_key()\n        if cursors.has_duplicates(entry.key):\n            entry = cursors.keep_newest(entry.key)\n        output.write(entry)\n    return output.finalise()\n</code></pre>\n<p><strong>Bad (do not do this):</strong></p>\n<pre><code>def lsm_write(key, value):\n    append key-value pair to memtable          # English sentence -- wrong\n    if memtable exceeds size threshold:        # English condition -- wrong\n        flush memtable to a new SSTable        # English sentence -- wrong\n</code></pre>\n<pre><code>def lsm_write(key: str, value: bytes):  # typed signature + real Python -- wrong\n    self.lock.acquire()\n    self.memtable[key] = value\n    if len(self.memtable) &gt; self.threshold:\n        self.flush()\n    self.lock.release()\n</code></pre>\n<h2>Checklist Before Writing</h2>\n<ul>\n<li>Are all body lines calls (<code>object.verb(args)</code> or <code>verb(args)</code>), not English sentences?</li>\n<li>Are invented names intuitive -- would a reader guess what they do?</li>\n<li>Are if/else conditions also written as calls or simple expressions, not prose?</li>\n<li>Is every line a single idea?</li>\n</ul>\n<p>If yes, the pseudocode is done.</p>\n","files":[{"path":"SKILL.md","sizeBytes":4260,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
