Pymatgen commonly uses Å, degrees, eV, eV\u002Fatom, amu, and\n   g\u002Fcm³, but each API's documented contract is authoritative.\n3. State coordinate mode. `Structure` coordinates are fractional unless\n   `coords_are_cartesian=True`; `Molecule` coordinates are Cartesian.\n4. Inspect every parser warning. For CIF, preserve occupancy, site-merging,\n   stoichiometry, and correction warnings; do not silently accept fixes.\n5. Report disorder\u002Fpartial occupancies and oxidation-state decoration. Never\n   guess oxidation states implicitly.\n6. Run validation before symmetry, neighbor, transformation, conversion, or\n   thermodynamic analysis.\n7. Sweep symmetry tolerances and report `symprec` in Å and\n   `angle_tolerance` in degrees with every assignment.\n8. Treat transformations as new artifacts. Preserve the input, parameters,\n   software versions, warnings, and parent\u002Fchild checksums.\n9. Before conversion, identify representation loss. Write only to a new path\n   and round-trip-check scientifically relevant properties.\n10. Build phase diagrams only from compatible total energies and correction\n    schemes. A computed hull is conditional on the supplied entry set.\n11. Keep all database access off by default. Disclose endpoint, filters,\n    fields, result limit, cache behavior, output, license, and citation before\n    an explicit execution step.\n12. Preserve an artifact manifest. Never use pickle or load an untrusted\n    general object graph; use schema-validated JSON and explicit constructors.\n\n## Core objects\n\nUse the public convenience imports:\n\n```python\nfrom pymatgen.core import Composition, Element, Lattice, Molecule, Structure\n\ncomposition = Composition(\"LiFePO4\", strict=True)\niron = Element(\"Fe\")\n\nlattice = Lattice.cubic(5.64)  # Å\nstructure = Structure(\n    lattice,\n    [\"Na\", \"Cl\"],\n    [[0, 0, 0], [0.5, 0.5, 0.5]],\n    coords_are_cartesian=False,\n    validate_proximity=True,\n)\n\nmolecule = Molecule(\n    [\"O\", \"H\", \"H\"],\n    [[0.0, 0.0, 0.0], [0.758, 0.0, 0.504], [-0.758, 0.0, 0.504]],\n    charge=0,\n    spin_multiplicity=1,\n)\n```\n\n`Structure` and `Molecule` are mutable; use `IStructure`\u002F`IMolecule` or an\nexplicit copy when mutation would compromise provenance. See\n[core classes](references\u002Fcore_classes.md).\n\n## Safe local structure intake\n\nPrefer the bundled validator, which captures CIF and Python warnings and\nreports units, occupancy, disorder, oxidation states, periodicity, coordinate\nmode, and minimum distances:\n\n```bash\npython scripts\u002Fcomposition_structure_validator.py composition \"Fe2O3\"\npython scripts\u002Fcomposition_structure_validator.py structure structure.cif\npython scripts\u002Fstructure_analyzer.py structure.cif --symmetry\n```\n\nThe distance report compares distinct sites under PBC; it excludes images of\nthe same site and returns null for a one-site cell. It is not a complete check\nfor contacts across very short lattice vectors. Plain Structure JSON is read\nstrictly; nested MSON objects, YAML, and compressed JSON are refused.\n\nFor direct CIF work, use the current parser method and inspect both warning\nchannels:\n\n```python\nimport warnings\nfrom pymatgen.io.cif import CifParser\n\nwith warnings.catch_warnings(record=True) as caught:\n    warnings.simplefilter(\"always\")\n    parser = CifParser(\"input.cif\", check_cif=True)\n    structures = parser.parse_structures(\n        primitive=False,\n        check_occu=True,\n        on_error=\"raise\",\n    )\n\nparser_messages = list(parser.warnings)\npython_messages = [str(item.message) for item in caught]\n```\n\nDo not parse untrusted files in a privileged process. A critical malicious-CIF\ncode-execution flaw affected pymatgen through 2024.2.8 and was fixed in\n2024.2.20; the pinned release is newer, but parsers still process attacker\ncontrolled input. Use isolation and CPU\u002FRAM\u002Fdisk\u002Ftime limits.\n\n## Symmetry\n\nSpace-group assignment depends on tolerances and structure quality:\n\n```python\nfrom pymatgen.symmetry.analyzer import SpacegroupAnalyzer\n\nanalyzer = SpacegroupAnalyzer(\n    structure,\n    symprec=0.01,          # Å\n    angle_tolerance=5.0,   # degrees\n)\nsymbol = analyzer.get_space_group_symbol()\nnumber = analyzer.get_space_group_number()\n```\n\nThe Materials Project pipeline commonly uses `symprec=0.1 Å`, while pymatgen's\ndocumented default is `0.01 Å`; these can produce different assignments.\nGenerate a sensitivity report instead of changing tolerance until a preferred\nanswer appears:\n\n```bash\npython scripts\u002Fsymmetry_sensitivity_report.py structure.cif \\\n  --symprec 0.001,0.01,0.1 --angle-tolerance 1,5\n```\n\nSee [analysis modules](references\u002Fanalysis_modules.md).\n\n## Conversion and parser\u002Fwriter I\u002FO\n\nPlan first; the planner does not open files or import pymatgen:\n\n```bash\npython scripts\u002Fio_conversion_plan.py \\\n  --input input.cif --input-format cif \\\n  --output POSCAR.new --output-format poscar \\\n  --periodic --coordinate-mode direct\n```\n\nThen convert to a new path with explicit loss acknowledgement:\n\n```bash\npython scripts\u002Fstructure_converter.py input.cif POSCAR.new \\\n  --output-format poscar --coordinate-mode direct --allow-lossy \\\n  --acknowledge-parser-warnings\n```\n\nCIF, POSCAR, XYZ, and JSON do not preserve the same semantics. Check lattice,\nperiodicity, coordinate mode, species ordering, selective dynamics, site\nproperties, oxidation states, labels, and disorder after every conversion.\nSee [I\u002FO formats](references\u002Fio_formats.md).\n\n## Transformations and provenance\n\nTransform a copy and preserve history:\n\n```python\nfrom pymatgen.alchemy.materials import TransformedStructure\nfrom pymatgen.transformations.standard_transformations import (\n    SubstitutionTransformation,\n    SupercellTransformation,\n)\n\ntracked = TransformedStructure(structure.copy(), [])\ntracked.append_transformation(SupercellTransformation([2, 2, 2]))\ntracked.append_transformation(SubstitutionTransformation({\"Na\": \"K\"}))\nderived = tracked.final_structure\nhistory = tracked.history\n```\n\nOne-to-many ordering, doping, slab, and magnetic transformations can expand\ncombinatorially or invoke optional executables. Bound candidates, sites,\nsupercell size, runtime, and output count. See\n[transformations and workflows](references\u002Ftransformations_workflows.md).\n\n## Local phase diagrams\n\nThe bundled generator is offline and accepts only a strict JSON schema with\ntotal eV per entry and provenance:\n\n```json\n{\n  \"schema_version\": \"1.0\",\n  \"energy_unit\": \"eV\",\n  \"energy_basis\": \"total_per_entry\",\n  \"provenance\": {\n    \"source\": \"reviewed local calculations\",\n    \"method\": \"one compatible energy\u002Fcorrection scheme\"\n  },\n  \"entries\": [\n    {\n      \"entry_id\": \"local-Li\",\n      \"composition\": \"Li\",\n      \"energy_eV\": -1.0,\n      \"provenance\": {\"source\": \"calculation manifest sha256:...\"}\n    },\n    {\n      \"entry_id\": \"local-O2\", \"composition\": \"O2\", \"energy_eV\": -2.0,\n      \"provenance\": {\"source\": \"synthetic demonstration\"}\n    },\n    {\n      \"entry_id\": \"local-Li2O\", \"composition\": \"Li2O\", \"energy_eV\": -4.0,\n      \"provenance\": {\"source\": \"synthetic demonstration\"}\n    }\n  ]\n}\n```\n\n```bash\npython scripts\u002Fphase_diagram_generator.py entries.json --analyze Li2O\n```\n\nThese invented energies demonstrate the total-energy schema, not material\npredictions. `--plot phase.new.svg` uses the local Matplotlib backend.\n\nElemental endpoints and all competing phases must be present. Do not mix raw\nenergies from different functionals, pseudopotentials, magnetic states, or\ncorrection conventions. Computed on-hull status is not experimental stability.\n\nFor a mixed GGA\u002FGGA+U\u002Fr2SCAN hull, Materials Project corrections can depend on\nthe chemical system used to build the hull. Do not transplant corrected entries\nfrom their home systems into a new system unchanged. Follow the documented\n`MaterialsProjectDFTMixingScheme` workflow on the complete target-system entry\nset, retain raw energies and correction records, and inspect excluded entries.\nThe [official phase-diagram methodology](https:\u002F\u002Fdocs.materialsproject.org\u002Fmethodology\u002Fmaterials-methodology\u002Fthermodynamic-stability\u002Fphase-diagrams-pds)\ndistinguishes this from the earlier GGA\u002FGGA+U-only correction workflow.\n\n## Band structures, DOS, VASP, and Q-Chem\n\nParse only the data needed:\n\n```python\nfrom pymatgen.io.vasp import Vasprun\n\nrun = Vasprun(\n    \"vasprun.xml\",\n    parse_dos=True,\n    parse_eigen=True,\n    parse_projected_eigen=False,\n    parse_potcar_file=False,\n)\nband_structure = run.get_band_structure(line_mode=True)\nband_gap = band_structure.get_band_gap()\ncomplete_dos = run.complete_dos\n```\n\nProjected eigenvalues can require extreme memory. Verify convergence, k-path,\nspin\u002FSOC settings, Fermi-level conventions, smearing, and projection basis\nbefore interpreting gaps or DOS. A parser success is not a converged\ncalculation.\n\nCurrent Q-Chem interfaces are `pymatgen.io.qchem.inputs.QCInput` and\n`pymatgen.io.qchem.outputs.QCOutput`:\n\n```python\nfrom pymatgen.io.qchem.inputs import QCInput\n\njob = QCInput(\n    molecule,\n    rem={\"job_type\": \"sp\", \"method\": \"wb97x-v\", \"basis\": \"def2-svpd\"},\n)\ntext = str(job)\n```\n\nPymatgen writes inputs and parses outputs; it does not grant a VASP or Q-Chem\nlicense or establish method validity. POTCAR files are VASP-licensed and are\nnot distributed by pymatgen. Never redistribute them or scan unrelated\ndirectories for them. Optional tools such as enumlib, Bader, packmol, ffmpeg,\nand Zeo++ are native\u002Fexternal executables: review provenance, licenses, argv,\nworking directory, and resource limits before a separate explicit invocation.\n\n## Materials Project: plan before network\n\nUse only:\n\n```python\nfrom mp_api.client import MPRester\n```\n\nThe client accepts `MP_API_KEY` when constructed. Supply only that named\nenvironment variable through the user's shell or secret manager. Do not accept\nthe key as a CLI argument, traverse `.env` files, dump environment variables,\nor print exception data without redaction.\n\nDry-run planning is the default:\n\n```bash\npython scripts\u002Fmp_query.py \\\n  --chemsys Li-Fe-O \\\n  --energy-above-hull 0 0.05 \\\n  --fields formula_pretty,energy_above_hull,band_gap,origins \\\n  --limit 25\n```\n\nOnly `--execute` permits one bounded summary query and requires a new output:\n\n```bash\npython scripts\u002Fmp_query.py \\\n  --material-id mp-149 \\\n  --fields formula_pretty,structure,origins,last_updated \\\n  --limit 1 --output mp-149.json --execute\n```\n\nThe CLI sets `num_chunks=1`, requires explicit fields and filters, caps results,\ndoes not implement an implicit result cache, and never overwrites output.\nBoth legacy IDs (`mp-149`) and AlphaIDs (`mp-aaaaaaft`) are accepted; the SDK\nnormalizes equivalent spellings. The CLI fixes the official API endpoint.\n`MPRester` initialization also performs compatibility\u002Fheartbeat metadata\nrequests; the plan discloses these, disables the platform-detail user agent and\nlocal database-version notification log, and records the returned database\nversion. The summary workflow does not request full-dataset cache downloads.\n`mp-api` 0.46.5 retries HTTP 429\u002F502\u002F504 according to its own configured policy\nand respects `Retry-After`; do not invent a numeric service quota or add an\nunbounded retry loop. Initialization heartbeat calls use a separate transport\nwithout a timeout in this SDK; use an outer process deadline when needed.\nThe JSON byte cap bounds the saved artifact, not bytes already downloaded.\n\nMaterials Project core values are computed, method-dependent data—not\nexperimental truth. PBE commonly overestimates lattice parameters and\nsystematically underestimates band gaps; aggregated values can change across\ndatabase releases. Preserve retrieval time, query, fields, material\u002Ftask\norigins, database release when available, client versions, CC BY attribution,\nand the canonical plus property-specific citations. See\n[Materials Project API](references\u002Fmaterials_project_api.md).\n\n## Bundled CLIs\n\nAll CLIs have dependency-free `--help`, lazy scientific imports, bounded JSON,\nand no implicit network:\n\n- `scripts\u002Fcomposition_structure_validator.py` — strict composition\u002Fstructure\n  checks; optional oxidation-state guessing is explicit and bounded.\n- `scripts\u002Fstructure_analyzer.py` — bounded lattice, sites, symmetry, distance,\n  and optional CrystalNN report.\n- `scripts\u002Fsymmetry_sensitivity_report.py` — tolerance-grid space groups.\n- `scripts\u002Fio_conversion_plan.py` — dependency-free representation-loss plan.\n- `scripts\u002Fstructure_converter.py` — one-file conversion to a new path.\n- `scripts\u002Fphase_diagram_generator.py` — strict local computed-entry hull.\n- `scripts\u002Fmp_query.py` — dry-run MP query plan and opt-in bounded client.\n- `scripts\u002Fartifact_manifest.py` — checksums, versions, sources, and provenance.\n\nUse:\n\n```bash\npython scripts\u002Fartifact_manifest.py \\\n  --artifact input.cif --artifact analysis.json \\\n  --workflow \"local symmetry sensitivity\" --output manifest.json\n```\n\n## References\n\n- [Core classes](references\u002Fcore_classes.md)\n- [I\u002FO formats, VASP, and Q-Chem](references\u002Fio_formats.md)\n- [Analysis, symmetry, phase diagrams, bands, and DOS](references\u002Fanalysis_modules.md)\n- [Transformations and workflows](references\u002Ftransformations_workflows.md)\n- [Materials Project API, provenance, license, and limits](references\u002Fmaterials_project_api.md)\n\n## Sources (verified 2026-09-30)\n\n- [pymatgen 2026.9.24 on PyPI](https:\u002F\u002Fpypi.org\u002Fproject\u002Fpymatgen\u002F)\n- [pymatgen-core 2026.9.23 on PyPI](https:\u002F\u002Fpypi.org\u002Fproject\u002Fpymatgen-core\u002F)\n- [pymatgen API documentation](https:\u002F\u002Fpymatgen.org\u002F)\n- [pymatgen changelog](https:\u002F\u002Fpymatgen.org\u002FCHANGES.html)\n- [mp-api 0.46.5 on PyPI](https:\u002F\u002Fpypi.org\u002Fproject\u002Fmp-api\u002F)\n- [Materials Project API getting started](https:\u002F\u002Fdocs.materialsproject.org\u002Fdownloading-data\u002Fusing-the-api\u002Fgetting-started)\n- [Materials Project query guide](https:\u002F\u002Fdocs.materialsproject.org\u002Fdownloading-data\u002Fusing-the-api\u002Fquerying-data)\n- [Materials Project FAQ and computed-data caveats](https:\u002F\u002Fdocs.materialsproject.org\u002Ffrequently-asked-questions)\n- [Materials Project citation page](https:\u002F\u002Fmaterialsproject.org\u002Fabout\u002Fcite)\n- [Official tutorial series endorsed by pymatgen](https:\u002F\u002Fgithub.com\u002Fcomputron\u002Fpymatgen_tutorials)\n\n## Citing Scientific Agent Skills\n\nThis skill is part of Scientific Agent Skills by K-Dense.

Never use pickle or load an untrusted\n    general object graph; use schema-validated JSON and explicit constructors.\n\n## Core objects\n\nUse the public convenience imports:\n\n```python\nfrom pymatgen.core import Composition, Element, Lattice, Molecule, Structure\n\ncomposition = Composition(\"LiFePO4\", strict=True)\niron = Element(\"Fe\")\n\nlattice = Lattice.cubic(5.64)  # Å\nstructure = Structure(\n    lattice,\n    [\"Na\", \"Cl\"],\n    [[0, 0, 0], [0.5, 0.5, 0.5]],\n    coords_are_cartesian=False,\n    validate_proximity=True,\n)\n\nmolecule = Molecule(\n    [\"O\", \"H\", \"H\"],\n    [[0.0, 0.0, 0.0], [0.758, 0.0, 0.504], [-0.758, 0.0, 0.504]],\n    charge=0,\n    spin_multiplicity=1,\n)\n```\n\n`Structure` and `Molecule` are mutable; use `IStructure`\u002F`IMolecule` or an\nexplicit copy when mutation would compromise provenance. See\n[core classes](references\u002Fcore_classes.md).\n\n## Safe local structure intake\n\nPrefer the bundled validator, which captures CIF and Python warnings and\nreports units, occupancy, disorder, oxidation states, periodicity, coordinate\nmode, and minimum distances:\n\n```bash\npython scripts\u002Fcomposition_structure_validator.py composition \"Fe2O3\"\npython scripts\u002Fcomposition_structure_validator.py structure structure.cif\npython scripts\u002Fstructure_analyzer.py structure.cif --symmetry\n```\n\nThe distance report compares distinct sites under PBC; it excludes images of\nthe same site and returns null for a one-site cell. It is not a complete check\nfor contacts across very short lattice vectors. Plain Structure JSON is read\nstrictly; nested MSON objects, YAML, and compressed JSON are refused.\n\nFor direct CIF work, use the current parser method and inspect both warning\nchannels:\n\n```python\nimport warnings\nfrom pymatgen.io.cif import CifParser\n\nwith warnings.catch_warnings(record=True) as caught:\n    warnings.simplefilter(\"always\")\n    parser = CifParser(\"input.cif\", check_cif=True)\n    structures = parser.parse_structures(\n        primitive=False,\n        check_occu=True,\n        on_error=\"raise\",\n    )\n\nparser_messages = list(parser.warnings)\npython_messages = [str(item.message) for item in caught]\n```\n\nDo not parse untrusted files in a privileged process. A critical malicious-CIF\ncode-execution flaw affected pymatgen through 2024.2.8 and was fixed in\n2024.2.20; the pinned release is newer, but parsers still process attacker\ncontrolled input. Use isolation and CPU\u002FRAM\u002Fdisk\u002Ftime limits.\n\n## Symmetry\n\nSpace-group assignment depends on tolerances and structure quality:\n\n```python\nfrom pymatgen.symmetry.analyzer import SpacegroupAnalyzer\n\nanalyzer = SpacegroupAnalyzer(\n    structure,\n    symprec=0.01,          # Å\n    angle_tolerance=5.0,   # degrees\n)\nsymbol = analyzer.get_space_group_symbol()\nnumber = analyzer.get_space_group_number()\n```\n\nThe Materials Project pipeline commonly uses `symprec=0.1 Å`, while pymatgen's\ndocumented default is `0.01 Å`; these can produce different assignments.\nGenerate a sensitivity report instead of changing tolerance until a preferred\nanswer appears:\n\n```bash\npython scripts\u002Fsymmetry_sensitivity_report.py structure.cif \\\n  --symprec 0.001,0.01,0.1 --angle-tolerance 1,5\n```\n\nSee [analysis modules](references\u002Fanalysis_modules.md).\n\n## Conversion and parser\u002Fwriter I\u002FO\n\nPlan first; the planner does not open files or import pymatgen:\n\n```bash\npython scripts\u002Fio_conversion_plan.py \\\n  --input input.cif --input-format cif \\\n  --output POSCAR.new --output-format poscar \\\n  --periodic --coordinate-mode direct\n```\n\nThen convert to a new path with explicit loss acknowledgement:\n\n```bash\npython scripts\u002Fstructure_converter.py input.cif POSCAR.new \\\n  --output-format poscar --coordinate-mode direct --allow-lossy \\\n  --acknowledge-parser-warnings\n```\n\nCIF, POSCAR, XYZ, and JSON do not preserve the same semantics. Check lattice,\nperiodicity, coordinate mode, species ordering, selective dynamics, site\nproperties, oxidation states, labels, and disorder after every conversion.\nSee [I\u002FO formats](references\u002Fio_formats.md).\n\n## Transformations and provenance\n\nTransform a copy and preserve history:\n\n```python\nfrom pymatgen.alchemy.materials import TransformedStructure\nfrom pymatgen.transformations.standard_transformations import (\n    SubstitutionTransformation,\n    SupercellTransformation,\n)\n\ntracked = TransformedStructure(structure.copy(), [])\ntracked.append_transformation(SupercellTransformation([2, 2, 2]))\ntracked.append_transformation(SubstitutionTransformation({\"Na\": \"K\"}))\nderived = tracked.final_structure\nhistory = tracked.history\n```\n\nOne-to-many ordering, doping, slab, and magnetic transformations can expand\ncombinatorially or invoke optional executables. Bound candidates, sites,\nsupercell size, runtime, and output count. See\n[transformations and workflows](references\u002Ftransformations_workflows.md).\n\n## Local phase diagrams\n\nThe bundled generator is offline and accepts only a strict JSON schema with\ntotal eV per entry and provenance:\n\n```json\n{\n  \"schema_version\": \"1.0\",\n  \"energy_unit\": \"eV\",\n  \"energy_basis\": \"total_per_entry\",\n  \"provenance\": {\n    \"source\": \"reviewed local calculations\",\n    \"method\": \"one compatible energy\u002Fcorrection scheme\"\n  },\n  \"entries\": [\n    {\n      \"entry_id\": \"local-Li\",\n      \"composition\": \"Li\",\n      \"energy_eV\": -1.0,\n      \"provenance\": {\"source\": \"calculation manifest sha256:...\"}\n    },\n    {\n      \"entry_id\": \"local-O2\", \"composition\": \"O2\", \"energy_eV\": -2.0,\n      \"provenance\": {\"source\": \"synthetic demonstration\"}\n    },\n    {\n      \"entry_id\": \"local-Li2O\", \"composition\": \"Li2O\", \"energy_eV\": -4.0,\n      \"provenance\": {\"source\": \"synthetic demonstration\"}\n    }\n  ]\n}\n```\n\n```bash\npython scripts\u002Fphase_diagram_generator.py entries.json --analyze Li2O\n```\n\nThese invented energies demonstrate the total-energy schema, not material\npredictions. `--plot phase.new.svg` uses the local Matplotlib backend.\n\nElemental endpoints and all competing phases must be present. Do not mix raw\nenergies from different functionals, pseudopotentials, magnetic states, or\ncorrection conventions. Computed on-hull status is not experimental stability.\n\nFor a mixed GGA\u002FGGA+U\u002Fr2SCAN hull, Materials Project corrections can depend on\nthe chemical system used to build the hull. Do not transplant corrected entries\nfrom their home systems into a new system unchanged. Follow the documented\n`MaterialsProjectDFTMixingScheme` workflow on the complete target-system entry\nset, retain raw energies and correction records, and inspect excluded entries.\nThe [official phase-diagram methodology](https:\u002F\u002Fdocs.materialsproject.org\u002Fmethodology\u002Fmaterials-methodology\u002Fthermodynamic-stability\u002Fphase-diagrams-pds)\ndistinguishes this from the earlier GGA\u002FGGA+U-only correction workflow.\n\n## Band structures, DOS, VASP, and Q-Chem\n\nParse only the data needed:\n\n```python\nfrom pymatgen.io.vasp import Vasprun\n\nrun = Vasprun(\n    \"vasprun.xml\",\n    parse_dos=True,\n    parse_eigen=True,\n    parse_projected_eigen=False,\n    parse_potcar_file=False,\n)\nband_structure = run.get_band_structure(line_mode=True)\nband_gap = band_structure.get_band_gap()\ncomplete_dos = run.complete_dos\n```\n\nProjected eigenvalues can require extreme memory. Verify convergence, k-path,\nspin\u002FSOC settings, Fermi-level conventions, smearing, and projection basis\nbefore interpreting gaps or DOS. A parser success is not a converged\ncalculation.\n\nCurrent Q-Chem interfaces are `pymatgen.io.qchem.inputs.QCInput` and\n`pymatgen.io.qchem.outputs.QCOutput`:\n\n```python\nfrom pymatgen.io.qchem.inputs import QCInput\n\njob = QCInput(\n    molecule,\n    rem={\"job_type\": \"sp\", \"method\": \"wb97x-v\", \"basis\": \"def2-svpd\"},\n)\ntext = str(job)\n```\n\nPymatgen writes inputs and parses outputs; it does not grant a VASP or Q-Chem\nlicense or establish method validity. POTCAR files are VASP-licensed and are\nnot distributed by pymatgen. Never redistribute them or scan unrelated\ndirectories for them. Optional tools such as enumlib, Bader, packmol, ffmpeg,\nand Zeo++ are native\u002Fexternal executables: review provenance, licenses, argv,\nworking directory, and resource limits before a separate explicit invocation.\n\n## Materials Project: plan before network\n\nUse only:\n\n```python\nfrom mp_api.client import MPRester\n```\n\nThe client accepts `MP_API_KEY` when constructed. Supply only that named\nenvironment variable through the user's shell or secret manager. Do not accept\nthe key as a CLI argument, traverse `.env` files, dump environment variables,\nor print exception data without redaction.\n\nDry-run planning is the default:\n\n```bash\npython scripts\u002Fmp_query.py \\\n  --chemsys Li-Fe-O \\\n  --energy-above-hull 0 0.05 \\\n  --fields formula_pretty,energy_above_hull,band_gap,origins \\\n  --limit 25\n```\n\nOnly `--execute` permits one bounded summary query and requires a new output:\n\n```bash\npython scripts\u002Fmp_query.py \\\n  --material-id mp-149 \\\n  --fields formula_pretty,structure,origins,last_updated \\\n  --limit 1 --output mp-149.json --execute\n```\n\nThe CLI sets `num_chunks=1`, requires explicit fields and filters, caps results,\ndoes not implement an implicit result cache, and never overwrites output.\nBoth legacy IDs (`mp-149`) and AlphaIDs (`mp-aaaaaaft`) are accepted; the SDK\nnormalizes equivalent spellings. The CLI fixes the official API endpoint.\n`MPRester` initialization also performs compatibility\u002Fheartbeat metadata\nrequests; the plan discloses these, disables the platform-detail user agent and\nlocal database-version notification log, and records the returned database\nversion. The summary workflow does not request full-dataset cache downloads.\n`mp-api` 0.46.5 retries HTTP 429\u002F502\u002F504 according to its own configured policy\nand respects `Retry-After`; do not invent a numeric service quota or add an\nunbounded retry loop. Initialization heartbeat calls use a separate transport\nwithout a timeout in this SDK; use an outer process deadline when needed.\nThe JSON byte cap bounds the saved artifact, not bytes already downloaded.\n\nMaterials Project core values are computed, method-dependent data—not\nexperimental truth. PBE commonly overestimates lattice parameters and\nsystematically underestimates band gaps; aggregated values can change across\ndatabase releases. Preserve retrieval time, query, fields, material\u002Ftask\norigins, database release when available, client versions, CC BY attribution,\nand the canonical plus property-specific citations. See\n[Materials Project API](references\u002Fmaterials_project_api.md).\n\n## Bundled CLIs\n\nAll CLIs have dependency-free `--help`, lazy scientific imports, bounded JSON,\nand no implicit network:\n\n- `scripts\u002Fcomposition_structure_validator.py` — strict composition\u002Fstructure\n  checks; optional oxidation-state guessing is explicit and bounded.\n- `scripts\u002Fstructure_analyzer.py` — bounded lattice, sites, symmetry, distance,\n  and optional CrystalNN report.\n- `scripts\u002Fsymmetry_sensitivity_report.py` — tolerance-grid space groups.\n- `scripts\u002Fio_conversion_plan.py` — dependency-free representation-loss plan.\n- `scripts\u002Fstructure_converter.py` — one-file conversion to a new path.\n- `scripts\u002Fphase_diagram_generator.py` — strict local computed-entry hull.\n- `scripts\u002Fmp_query.py` — dry-run MP query plan and opt-in bounded client.\n- `scripts\u002Fartifact_manifest.py` — checksums, versions, sources, and provenance.\n\nUse:\n\n```bash\npython scripts\u002Fartifact_manifest.py \\\n  --artifact input.cif --artifact analysis.json \\\n  --workflow \"local symmetry sensitivity\" --output manifest.json\n```\n\n## References\n\n- [Core classes](references\u002Fcore_classes.md)\n- [I\u002FO formats, VASP, and Q-Chem](references\u002Fio_formats.md)\n- [Analysis, symmetry, phase diagrams, bands, and DOS](references\u002Fanalysis_modules.md)\n- [Transformations and workflows](references\u002Ftransformations_workflows.md)\n- [Materials Project API, provenance, license, and limits](references\u002Fmaterials_project_api.md)\n\n## Sources (verified 2026-09-30)\n\n- [pymatgen 2026.9.24 on PyPI](https:\u002F\u002Fpypi.org\u002Fproject\u002Fpymatgen\u002F)\n- [pymatgen-core 2026.9.23 on PyPI](https:\u002F\u002Fpypi.org\u002Fproject\u002Fpymatgen-core\u002F)\n- [pymatgen API documentation](https:\u002F\u002Fpymatgen.org\u002F)\n- [pymatgen changelog](https:\u002F\u002Fpymatgen.org\u002FCHANGES.html)\n- [mp-api 0.46.5 on PyPI](https:\u002F\u002Fpypi.org\u002Fproject\u002Fmp-api\u002F)\n- [Materials Project API getting started](https:\u002F\u002Fdocs.materialsproject.org\u002Fdownloading-data\u002Fusing-the-api\u002Fgetting-started)\n- [Materials Project query guide](https:\u002F\u002Fdocs.materialsproject.org\u002Fdownloading-data\u002Fusing-the-api\u002Fquerying-data)\n- [Materials Project FAQ and computed-data caveats](https:\u002F\u002Fdocs.materialsproject.org\u002Ffrequently-asked-questions)\n- [Materials Project citation page](https:\u002F\u002Fmaterialsproject.org\u002Fabout\u002Fcite)\n- [Official tutorial series endorsed by pymatgen](https:\u002F\u002Fgithub.com\u002Fcomputron\u002Fpymatgen_tutorials)\n\n## Citing Scientific Agent Skills\n\nThis skill is part of Scientific Agent Skills by K-Dense.
