+description: Use when planning, implementing, validating, or correcting Abaqus User Subroutine Fortran work with Intel oneAPI, no-Abaqus tests, Abaqus opt-in validation, and RED/GREEN/VERIFY evidence.
+---
+
+# Abaqus Fortran TDD
+
+Use this skill to keep Abaqus User Subroutine Fortran work test-first, no-Abaqus compatible by default, and bounded by approved upstream contracts.
+
+## Inputs
+
+Read first:
+
+- `AGENTS.md`
+- `docs/ABAQUS_SUBROUTINE_AGENT_DESIGN.md`
+- `docs/implementation-plans/README.md`
+- `docs/build-test-reports/README.md`
+- `docs/corrections/README.md`
+- Related requirements, formulation, numerical review, interface, and test model documents
+
+## Workflow
+
+1. For planning, convert upstream documents into ordered Fortran tasks and test ids.
+2. For implementation, follow `RED -> GREEN -> VERIFY`.
+3. RED: write the planned no-Abaqus Fortran/Python driver test first and run it to verify expected failure.
+4. GREEN: implement the minimum Fortran kernel, Abaqus wrapper, or manifest change needed for the task.
+5. VERIFY: run the targeted command, then `python scripts/validate_fortran.py`, `python scripts/validate_reference_artifacts.py`, and `python scripts/validate_workspace.py`.
+6. Use Intel oneAPI Fortran discovery. Prefer `ifx`; use `ifort` when `ifx` is unavailable.
+7. For failure triage, classify as `fortran-compile | link | no-abaqus-test | abaqus-validation | reference-artifact | harness | environment | upstream-contract`.
+
+## Output Contract
+
+Produce one of these, depending on role: `docs/implementation-plans/<feature-id>-implementation-plan.md`, an implementation report with RED/GREEN/VERIFY evidence, `docs/build-test-reports/<feature-id>-build-test.md`, or `docs/corrections/<feature-id>-correction.md`.
+
+## Boundaries
+
+- Do not change requirements, formulations, interface contracts, test model contracts, reference artifacts, or tolerance policies unless explicitly asked.
+- Do not run Abaqus unless `HARNESS_ABAQUS_VALIDATION=run` and explicit commands are provided.
+- Do not generate reference CSVs.
+- Do not approve release readiness.
+- Do not expand scope beyond the approved implementation plan.
+
+## Quality Gate
+
+- Every Fortran production change has a related no-Abaqus Fortran/Python driver test or existing failing test.
+- Every test records RED failure and GREEN pass evidence.
+- Fortran source remains compatible with Intel oneAPI `ifx` or `ifort`.
+- Validation evidence records command, exit code, stdout/stderr tail, and failure classification.
+
+## Handoff
+
+Send passing no-Abaqus and workspace evidence to Build/Test Executor Agent. Send implementation-owned failures to Correction Agent. Send reference artifact readiness to Reference Verification Agent.

+
+## Workflow
+
+1. Confirm analysis assumptions, element/material family, strain measure, stress measure, coordinate system, and units.
+2. Define Strong Form and Boundary Conditions when relevant.
+3. Define Weak or Variational Form and residual statement when relevant.
+4. Define discretization, kinematics, strain-displacement relations, and numerical integration.
+5. Define stress update, consistent tangent, state variables, and output recovery.
+6. Define Constitutive Contract without creating Fortran source layout.
+7. Record numerical risks and tests that should catch them.
+8. Write Algorithm Pseudocode at math level only.
+
+## Output Contract
+
+Produce or revise `docs/formulations/<feature-id>-formulation.md` with Strong Form and Boundary Conditions, Weak or Variational Form, Discretization, Kinematics, Constitutive Contract, Element Equations, Mapping and Numerical Integration, Output Recovery, Abaqus Subroutine Mapping, Numerical Risks, Algorithm Pseudocode, and Downstream Handoff.

+## Boundaries
+
+- Do not implement code.
+- Do not design Fortran source layout.
+- Do not choose file ownership.
+- Do not run Abaqus.
+- Do not generate reference CSVs.
+- Do not approve release readiness.
+
+## Quality Gate
+
+- Stress update, consistent tangent, and state variables are defined when the selected entry point requires them.
+- Element equations identify residual, tangent, stiffness, mass, or damping terms when applicable.
+- Output recovery identifies location, components, units, and coordinate system.
+- Numerical risks include rigid body modes, patch test, hourglass, locking, Jacobian, conditioning, tangent consistency, and convergence risks when relevant.
+
+## Handoff
+
+Send review-ready formulation to Numerical Review Agent, interface needs to I/O Definition Agent, model needs to Reference Model Agent, and implementation algorithm notes to Implementation Planning Agent.

+# Abaqus Subroutine Physics Sanity
+
+Use this skill to decide whether validation-passing Abaqus User Subroutine outputs are physically credible enough for readiness review. Physics sanity is the owned artifact for this skill.
+
+## Inputs
+
+Read first:
+
+- `AGENTS.md`
+- `docs/ABAQUS_SUBROUTINE_AGENT_DESIGN.md`
+- `docs/physics-evaluations/README.md`
+- Reference verification reports
+- Stored reference and generated CSVs
+- Requirements, formulation, interface, and test model documents
+
+## Workflow
+
+1. Check global equilibrium, reaction consistency, displacement direction, symmetry, and boundary condition effects.
+2. Check stress/strain signs, magnitudes, locations, coordinate systems, and state variable evolution.
+3. Check energy/residual quantities when available.
+4. Check model coverage for the claimed behavior.
+5. Classify failures as `physics-implausible | model-inadequate | artifact-gap | upstream-contract | needs-correction`.
+
+## Output Contract
+
+Produce or revise `docs/physics-evaluations/<feature-id>-physics-evaluation.md` with Input Evidence, Physics Checks, Failure Classification, Evaluation Verdict, Handoff Recommendation, and No-Change Assertion.
+
+## Boundaries
+
+- Do not edit source code.
+- Do not edit tests.
+- Do not run Abaqus.
+- Do not generate reference CSVs.
+- Do not change tolerances.
+- Do not approve release readiness.
+
+## Quality Gate
+
+- Physical checks are tied to requirements and model purpose.
+- Passing tolerance comparison is not treated as sufficient by itself.
+- Implausible results name the exact quantity, model, and likely owner.
+
+## Handoff
+
+Send implementation-owned physical failures to Correction Agent, inadequate model coverage to Reference Model Agent, and passing physics evidence to Release Agent.

+---
+
+# FEM Theory Query
+
+Use this skill as a portable domain router for finite element method and structural solver theory questions. Ground answers in a configured FEM wiki vault, then compose sibling skills instead of reimplementing their workflows.
+
+## FEM Vault Resolution
+
+Resolve the FEM wiki vault in this order:
+
+1. Skill-local config file: `vault-path.txt` in this skill folder. Read the first non-empty, non-comment line as the vault root path.
+2. Current project instructions: `AGENTS.md`, `CLAUDE.md`, or an equivalent section named `FEM Solver Theory Wiki`.
+3. Environment variable: `FEM_THEORY_WIKI_VAULT`.
+
+If no valid vault is found, ask the user for the vault path. A valid vault must contain `wiki/hot.md` or `wiki/index.md`.
+
+Keep `vault-path.txt` PC-specific. When the vault moves, update that file instead of editing this skill body.
+
+## Companion Skill Protocols
+
+This skill is an orchestrator. Do not reimplement sibling skills. Use the sibling skill instructions as authoritative when available.
+
+### Companion skill path resolution
+
+After reading `vault-path.txt`, call that value `FEM_VAULT_ROOT`. Resolve companion skill files from that absolute vault root:
+
+- `FEM_VAULT_ROOT\skills\think\SKILL.md`: use for non-trivial FEM formulation, solver architecture, ambiguity, tradeoffs, verification design, or gap assessment.
+- `FEM_VAULT_ROOT\skills\wiki-query\SKILL.md`: use for normal wiki-grounded answers from the configured FEM vault.
+- `FEM_VAULT_ROOT\skills\autoresearch\SKILL.md`: use only when the user explicitly asks to research, find sources, update the wiki, or fill missing wiki coverage.
+
+If the runtime provides a skill activation mechanism, activate the companion skill by name. If not, read the absolute companion `SKILL.md` path constructed from `vault-path.txt` and follow its workflow. If an absolute companion path does not exist, tell the user which path is missing and ask them to fix `vault-path.txt`.
+
+### Relative paths inside companion skills
+
+When a companion skill refers to another file by a relative path, resolve that path from the absolute directory of the companion skill file under `FEM_VAULT_ROOT`, not from the caller project or current working directory. Normalize `..` segments after joining paths. Keep the resolved path inside `FEM_VAULT_ROOT` unless the companion skill explicitly requires an external path.
+
+Examples from `FEM_VAULT_ROOT\skills\autoresearch\SKILL.md`:
+
+- `../wiki-cli/SKILL.md` resolves to `FEM_VAULT_ROOT\skills\wiki-cli\SKILL.md`.
+- `../../wiki/references/transport-fallback.md` resolves to `FEM_VAULT_ROOT\wiki\references\transport-fallback.md`.
+- `references/program.md` resolves to `FEM_VAULT_ROOT\skills\autoresearch\references\program.md`.
+
+If a resolved companion-relative path is missing, report the missing absolute path and ask the user to fix `vault-path.txt` or install the full `skills/` bundle.
+
+### How to use `think`
+
+Use `think` as a compact internal preflight before answering FEM solver questions.
+
+Do:
+- Identify the user's real question: theory derivation, implementation design, verification, comparison, or missing source.
+- Check whether you are relying on memory instead of wiki evidence.
+- Decide whether the answer can be handled by wiki query or needs autoresearch.
+- For complex questions, surface the reasoning structure briefly in the answer.
+
+Do not:
+- Print all 10 stages for routine factual questions.
+- Use `think` as a substitute for reading wiki sources.
+- Skip the `ACCEPT` step when the wiki has insufficient coverage.
+
+### How to use `wiki-query`
+
+Use `wiki-query` for the default answer path.
+
+Follow this order:
+
+1. Resolve the FEM vault path.
+2. Read `wiki/hot.md`.
+3. If needed, use `wiki-retrieve` when provisioned: `python scripts/retrieve.py "<question>" --top 5`.
+4. If retrieval is not provisioned or fails, read `wiki/index.md`.
+5. Read 3-7 relevant wiki pages.
+6. Synthesize with Obsidian wikilink citations.
+
+Do:
+- Cite every core claim with `[[Page Name]]`.
+- Prefer vault evidence over model memory.
+- Say clearly when the wiki lacks enough evidence.
+
+Do not:
+- Answer a vault-specific question from training data alone.
+- Open many pages when 3-7 are enough.
+- Write to the wiki unless the user explicitly asks.
+
+### How to use `autoresearch`
+
+Use `autoresearch` only for explicit research or wiki-expansion requests.
+
+Trigger examples:
+- "Find sources and strengthen this wiki coverage."
+- "If the wiki does not cover this, research it."
+- "Research and file this topic."
+- "Create source and concept pages for this topic."
+
+Before starting:
+- Tell the user it will use web search/fetch and write new wiki pages.
+- Mention that fetched content is subject to the `autoresearch` web egress hygiene rules.
+- Ask for approval unless the user already gave explicit approval in the same request.
+
+Do:
+- Read `FEM_VAULT_ROOT\skills\autoresearch\SKILL.md` and `FEM_VAULT_ROOT\skills\autoresearch\references\program.md`.
+- File results into the configured FEM vault, not the caller project.
+- Use wiki locks and transport rules from the sibling skill.
+
+Do not:
+- Run autoresearch for ordinary Q&A.
+- Fetch web sources silently.
+- Write into `.raw/` or `wiki/` without explicit user intent.
+
+## Answer Contract
+
+Answer in the user's language. For Korean questions, translate the section headings naturally.
+
+Use this structure unless the user asks for another format:
+
+- Summary conclusion
+- Formulation
+- Solver implementation view
+- Verification and benchmarks
+- Evidence
+- Wiki gap
+
+Every core technical claim should trace to wiki evidence. Use Obsidian wikilinks such as `[[Finite Element Method]]`, `[[Solid Element Stiffness Integration]]`, or the relevant source page. If the wiki does not cover a point, label it as a gap instead of presenting model memory as vault knowledge.
+
+## FEM Query Expansion
+
+When a user asks a short FEM question, expand the retrieval intent before searching:
+
+- Element formulation: shape functions, DOFs, Jacobian, `B` matrix, integration, load vector, result recovery.
+- Nonlinear solve: residual, tangent, Newton update, convergence norms, load/time increments, cutback policy.
+- Constitutive update: stress update, material tangent, state variables, return mapping, history evolution.
+- Dynamics/eigen: mass, damping, time integration, modal extraction, normalization, residual checks.
+- Contact/constraints: gap, normal/tangential law, penalty or multiplier enforcement, search, tangent contribution.
+- Verification: patch tests, convergence, benchmark problems, matrix checks, residual norms, source-solver comparison.
+
+Keep expansion internal unless showing it helps the user understand the answer.
+
+## Deployment Notes
+
+Distribute this skill with the whole `skills/` bundle so sibling paths remain valid. After installing or symlinking the bundle into another agent, update `vault-path.txt` for that PC or set `FEM_THEORY_WIKI_VAULT`.

+# Harness Review
+
+## Overview
+
+Use this skill to review Harness work against repository rules, Abaqus User Subroutine workflow, Fortran TDD, no-Abaqus validation, reference artifact contracts, and explicit Abaqus opt-in validation requirements. Prioritize bugs, regressions, missing tests, and rule violations.
+
+## Review Process
+
+1. Read `/AGENTS.md`, `/docs/ABAQUS_SUBROUTINE_AGENT_DESIGN.md`, `/docs/ARCHITECTURE.md`, and `/docs/ADR.md`.
+2. Inspect changed files with `git status --short` and `git diff`.
+3. Check architecture, Fortran test coverage, reference artifact contracts, critical rules, and validation readiness.
+4. Run relevant commands when feasible:
+   - `python -m unittest discover -s scripts -p "test_*.py"`
+   - `python scripts/validate_fortran.py`
+   - `python scripts/validate_reference_artifacts.py`
+   - `python scripts/validate_workspace.py`
+5. Lead with actionable findings. Keep summaries secondary.
+
+## Checklist
+
+| Item | Question |
+| --- | --- |
+| Workflow | Does the change fit the seven-step Abaqus User Subroutine process? |
+| Architecture | Does the change follow `docs/ARCHITECTURE.md` ownership boundaries? |
+| Tests | Are new or changed Fortran behaviors covered by no-Abaqus Fortran/Python tests or harness tests? |
+| TDD Guard | Would Fortran production edits be blocked without related tests? |
+| References | Do reference artifacts include `.inp`, source hash, Abaqus version, compiler version, msg/dat/log tail, and extracted CSV contracts when required? |
+| Abaqus Opt-in | Is `HARNESS_ABAQUS_VALIDATION=run` used only when explicitly configured? |
+| Build | Do the Python, Fortran, reference artifact, and workspace validation commands pass or report expected skips? |
+
+## Output Format
+
+If there are findings, list them first in severity order with file and line references when possible. Then include this table:
+
+| Item | Result | Notes |
+| --- | --- | --- |
+| Workflow | PASS/FAIL | {detail} |
+| Architecture | PASS/FAIL | {detail} |
+| Tests | PASS/FAIL | {detail} |
+| TDD Guard | PASS/FAIL | {detail} |
+| Reference Artifacts | PASS/FAIL | {detail} |
+| Abaqus Opt-in | PASS/FAIL | {detail} |
+| Validation | PASS/FAIL | {detail} |
+
+When there are no findings, say that clearly, then mention commands not run or remaining risk.

+2. Map the task to the seven-step Abaqus User Subroutine process: requirements, research, formulation, interface, TDD test models, Fortran implementation, validation.
+3. Discuss unresolved product or technical decisions with the user before writing phase files.
+4. Create or update `phases/index.json`, `phases/{task-name}/index.json`, and one `phases/{task-name}/stepN.md` per step.
+5. Run the phase with `python scripts/execute.py {task-name}` when asked. Use `--push` only when the user asks.
+
+## Step Design Rules
+
+- Scope each step to one artifact family: requirements, research, formulation, ABI/interface, no-Abaqus tests, Fortran source, validation, or documentation.
+- Make every step self-contained. Include required context and file paths.
+- Specify interfaces and signatures only when the step owns the interface contract.
+- Use executable acceptance criteria, not abstract statements.
+- For Fortran behavior changes, require tests first and name the no-Abaqus Fortran/Python driver test or `tests/fortran/manifest.json` entry.
+- Preserve the rule that Abaqus is not run by default; use `HARNESS_ABAQUS_VALIDATION=run` only when explicitly requested and configured.
+
+## Phase Files
+
+Create or update `phases/index.json`:
+
+```json
+{
+  "phases": [
+    {
+      "dir": "abaqus-subroutine-feature",
+      "status": "pending"
+    }
+  ]
+}
+```
+
+Create `phases/{task-name}/index.json`:
+
+```json
+{
+  "project": "FESA Harness",
+  "phase": "<task-name>",
+  "steps": [
+    { "step": 0, "name": "requirements", "status": "pending" },
+    { "step": 1, "name": "test-models", "status": "pending" },
+    { "step": 2, "name": "fortran-implementation", "status": "pending" }
+  ]
+}
+```
+
+Rules:
+
+- `project` comes from `AGENTS.md`.
+- `phase` matches the task directory name.
+- `steps[].step` starts at `0`.
+- Initial status is always `pending`.
+- Do not add timestamps when creating files. `scripts/execute.py` records timestamps.
+
+## Step Template
+
+```markdown
+# Step {N}: {name}
+
+## Read First
+
+- `/AGENTS.md`
+- `/docs/ABAQUS_SUBROUTINE_AGENT_DESIGN.md`
+- `/docs/ARCHITECTURE.md`
+- `/docs/ADR.md`
+- {previously created or modified files}
+
+## Task
+
+{Concrete instructions with file paths, interfaces, signatures, and rules.}
+
+## Tests To Write First
+
+- {Exact no-Abaqus Fortran/Python test file, manifest entry, or Python harness test to add before implementation.}
+
+## Acceptance Criteria
+
+```bash
+python -m unittest discover -s scripts -p "test_*.py"
+python scripts/validate_fortran.py
+python scripts/validate_reference_artifacts.py
+python scripts/validate_workspace.py
+```
+
+## Validation Notes
+
+- Use `HARNESS_ABAQUS_VALIDATION=run` only when the step explicitly owns Abaqus validation and the command contract is provided.
+- Update `phases/{task-name}/index.json` with `completed`, `error`, or `blocked` and a concrete summary/reason.
+
+## Forbidden
+
+- Do not add JavaScript/TypeScript/npm fallback.
+- Do not run Abaqus by default.
+- Do not generate reference CSVs unless the user explicitly authorized a reference-artifact phase.
+- Do not break existing tests.
+```
+
+## Execution And Recovery
+
+Run:
+
+```bash
+python scripts/execute.py {task-name}
+python scripts/execute.py {task-name} --push
+```
+
+If a step is `error`, fix the cause, set it back to `pending`, remove `error_message`, and rerun. If a step is `blocked`, resolve `blocked_reason`, set it back to `pending`, remove `blocked_reason`, and rerun.
