python-algorithms SKILL.md skillA
python-algorithms from lu1sdv/skillsmd is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add lu1sdv/skillsmd/python-algorithms@git:20261103.dccd64fPins git:20261103.dccd64f in mdr.lock. Pin the fingerprint instead.

Use when choosing Python collections or implementing and reviewing two pointers, sliding windows, binary search, prefix sums, monotonic stacks, hash-map patterns, two heaps, merge intervals, cyclic sort, BFS/DFS, backtracking, dynamic programming, greedy algorithms, topological sort, union-find, tries, bit manipulation, string search, order statistics, or dynamic range indexes. Covers invariants, complexity, mutation, duplicates, cycles, and boundary cases.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Python Algorithms Target **CPython 3.15**; latest stable patch verified **3.15.2 on 2026-11-03**. Treat a consuming project's older declared support as a compatibility constraint; report it before introducing baseline-only APIs or changing its support policy. ## Route by invariant | Task / pattern families | Load | |---|---| | Container choice, lists/trees/graphs, copying, ordering, real costs | [Collections and contracts](references/collections-and-contracts.md) | | 1 two pointers; 2 sliding window; 3 binary search; 4 prefix sum; 5 monotonic stack; 6 hash maps; 7 two heaps; 8 merge intervals; 9 cyclic sort | [Sequence patterns](references/sequence-patterns.md) | | 10 BFS/DFS and 0–1 BFS; 14 topological sort; 15 union-find; 16 trie; range indexes | [Graph and index patterns](references/graph-and-index-patterns.md) | | 11 backtracking; 12 dynamic programming; 13 greedy; 17 bit manipulation | [Search and optimization](references/search-and-optimization.md) | | 18 string search and palindrome radii; 19 selection and streaming top-k | [String search and selection](references/string-search-and-selection.md) | …

How to install
mdr add lu1sdv/skillsmd/python-algorithms@sha256:ebc92f4358443146The line at the top of this page pins the label git:20261103.dccd64f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
