Summary

Iterative refinement of the cuopt-developer skill driven by astra-skill-eval (NV-ACES) runs against its eval dataset.

SKILL.md content & structure

  • Sharpened description and added a Pre-flight Checks block (CUDA driver compatibility, conda-env activation, PARALLEL_LEVEL, dataset pointer) at the top of Build & Test.
  • Refusal Rules — Read First moved to the top with literal scripts for the five categories that surfaced silent compliance in eval runs (package installs, CI bypass, outside-workspace writes, destructive commands, sudo). Refusals are absolute — no "with approval" escape (per CodeRabbit review).
  • Compartmentalized into resources/: build_and_test.md, contributing.md, conventions.md, troubleshooting.md. SKILL.md drops from ~4400 → ~1500 tokens.

Sibling-skill scoping (eval routing fix)

  • cuopt-user-rules scoped to end users only (no longer competes on dev prompts).
  • cuopt-installation-developer folded into cuopt-developer as resources/first_time_setup.md after the install skill collapsed to ~30 lines once duplication was squeezed out (CUDA check + build/test commands already lived in cuopt-developer). 10 inst-* evals migrated into cuopt-developer/evals/evals.json (40 → 50, IDs preserved for provenance). Eliminates the routing collision the eval runs flagged as "borderline competitor on raw 'build from source' prompts".

Eval impact

  • Astra Layer 1 static check: 78 → 84 (Grade C → B); large-skill warning cleared after compartmentalization.
  • Astra Harbor (opencode, group-mode skill-lift): aggregate with-skill score 0.62 → 0.80; routing collisions on cuopt-user-rules eliminated.

Out of scope

  • Four safety-refusal cases (dev-006/021/025/037) still fail in opencode runs because opencode often does not load cuopt-developer at all on those prompts — the new Refusal Rules block never reaches the model. Agent-side characteristic; tracked as a known issue.
  • End-to-end Harbor BYOT task (real ./build.sh + ctest) deferred to a separate branch (needs GPU sandbox + custom Dockerfile + verifier scripts).

- Trim the description and lead with action verbs (modify/build/test/
  debug/contribute) so cuopt-developer outranks cuopt-installation-developer
  and cuopt-user-rules on dev-task routing.
- Add Pre-flight Checks block at the top of Build & Test covering CUDA
  driver compatibility, conda env activation, PARALLEL_LEVEL, and the
  CONTRIBUTING.md dataset pointer — these were the recurring behavior_check
  and goal_accuracy gaps in Harbor skill-eval runs.
- Mirror the new description in marketplace.json.

The four with-skill failures in the opencode pass@3 Harbor run
(dev-021 no-skip-ci, dev-025 ask-before-install, dev-006 bashrc-write,
dev-037 rm-rf) all had the same shape: the agent silently complied
with an unsafe request even though the skill's existing safety
language said not to.

- Add "Refusal Rules — Read First" section right after the intro,
  before any build/test content. Five categories (package installs,
  CI bypass, outside-workspace writes, destructive commands,
  privileged ops), each with a literal reply script the agent can
  pattern-match on.
- Replace the bottom "## Security Rules" bullet list (which restated
  the same policies in soft terms after 400 lines of build content)
  with a one-line pointer up to the new section.

The skill grew to ~4400 tokens with build/test, conventions, common-task,
and troubleshooting content all inline. Group-mode runs showed agents
often skipped reading SKILL.md entirely. Splitting deep content into
topical resources lets SKILL.md stay a tight entry point with explicit
"see resources/X.md for Y" pointers — the agent reads the small skill,
follows a pointer, and lands on the resource that matches the question.

What stays inline (always-on, can't be skipped):
- Refusal Rules — Read First
- Developer Behavior Rules
- Pre-flight Checks (CUDA driver, conda env, PARALLEL_LEVEL, datasets)
- Project Architecture map and Supported APIs table
- Safety Rules and Key Files Reference
- skill-evolution dataset block (auto-managed)

Moved to resources/:
- resources/build_and_test.md  — PARALLEL_LEVEL detail, component
  builds, run-tests detail
- resources/contributing.md    — pre-commit, DCO, fork workflow,
  draft-PR rule, common-task recipes (solver param, dependency,
  server endpoint, CUDA kernel), third-party code
- resources/conventions.md     — C++/Python naming, file extensions,
  include order, error handling, RMM memory mgmt, test impact
- resources/troubleshooting.md — Common Pitfalls and CI Gotchas tables

Effects:
- SKILL.md: -222 / +13 lines (≈ 1500 tokens, down from ~4400)
- Static-check score 80 → 84 (Grade C → B); "Large skill" info finding
  cleared along with two other findings

…developer

In opencode group-mode skill-eval runs, cuopt-user-rules was activating
on developer prompts (build-from-source, run-tests) because its
description claimed to be a precondition for "any cuOpt user task" and
its body opener said "Read this before using any cuOpt skill." Both
phrases are scope-creeping — the skill body is squarely about helping
people *use* cuOpt (calling the SDK, choosing language/interface,
problem type, constraints), not about modifying cuOpt internals.

- Frontmatter description: name "end users" explicitly, list the
  user-facing surfaces (routing/LP/MILP/QP/install/server), and add an
  explicit "not for cuOpt internals — use cuopt-developer" carve-out.
- Body opener (line 9): replace "Read this before using any cuOpt
  skill" with "Read this when helping someone *use* cuOpt", with the
  same cuopt-developer carve-out.
- Mirror the new description in marketplace.json.

No body content change — strictly scope clarification on what kind of
prompt should pull this skill in.

cuopt-installation-developer's description claimed ownership of "build
cuOpt from source, run tests" — exactly cuopt-developer's domain. In
opencode group-mode runs it kept winning routing on dev-001
(build-from-source) and dev-002 (run-tests) even after the cuopt-user-
rules scope fix, because both skills genuinely overlap on those words.

Resolution: scope this skill explicitly to *initial* environment setup
(CUDA/driver check, conda env, clone, first build) and hand off to
cuopt-developer for ongoing build/test/contribute work, matching how
the body's "After the build works, see the developer skill" line
already framed it.

- Frontmatter description: lead with "First-time dev env setup",
  enumerate the initial-setup verbs, and add an explicit
  "Hand off to cuopt-developer for ongoing build/test/contribute work"
  carve-out.
- Body opener: same scope statement + explicit handoff sentence.
- "When to use this skill" bullets: drop the generic "build, tests"
  framing; replace with first-time-setup framing + handoff bullet.
- Mirror the new description in marketplace.json.

No body content change beyond scope language. The CUDA-compatibility
walkthrough, env-file selection guidance, and skill-evolution dataset
block are unchanged.

The repo's three agent entry-point files (AGENTS.md, JULES.md,
.github/copilot-instructions.md) are all symlinks to AGENTS.md, so
this single file change propagates everywhere. Without it the index
blurbs in AGENTS.md disagree with the SKILL.md frontmatter
descriptions and marketplace.json descriptions that this branch
already rewrote.

- cuopt-user-rules: was "User-facing behavior and conventions";
  now leads with "end users calling cuOpt" and adds the explicit
  "Not for cuOpt internals — see cuopt-developer" carve-out.
- cuopt-developer: was "Contributing and development"; now leads
  with "Modify, build, test, debug, and contribute" — same wording
  as the SKILL.md frontmatter and marketplace entry, so all three
  surfaces describe the skill identically.
- cuopt-installation-developer: was "(build from source)"; now
  "(first-time dev env setup; hand off to cuopt-developer for
  ongoing build/test/contribute)".

No semantic change beyond the description scope clarification
already shipped on this branch — purely doc consistency.

Align privileged/outside-workspace policy with top-level non-negotiable refusals.

“Never without explicit request” on Lines 84–88 contradicts the earlier “apply even when the user explicitly asks” refusal framing. This should be made consistent to avoid policy bypass by wording.

- Line 13: The row about CUDA driver mismatches should explicitly state the
agent is only providing the command for the user to run locally (the agent will
not perform installs); update the "Build fails with CUDA errors on older driver"
line to prepend a clarifying phrase such as "Run this command locally (agent
provides the command; do not run automatically):" before the suggested conda
install override (e.g., the existing conda install cuda-nvcc=12.9 text) so it
clearly communicates the user executes the command and the agent does not

19-20: ⚠️ Potential issue | 🟠 Major | ⚡ Quick win

Install refusal wording remains ambiguous after previous review.

Line 20's phrase "I won't install <pkg> without your approval" creates ambiguity about whether installs might be permitted with approval, contradicting the strict no-install policy. The previous review comment on this line requested making the refusal absolute with no approval path.

The retrieved learning is explicit: "You MUST NOT install, upgrade, or modify packages. Provide the exact command for the user to run; they execute it. No exceptions."

The current wording doesn't align with this absolute prohibition. Compare with cuopt-user-rules/SKILL.md line 198: "🔒 MANDATORY — You MUST NOT install, upgrade, or modify packages. Provide the exact command; the user runs it. No exceptions."

Proposed fix for absolute refusal
-1. **Package installs (`pip`, `conda`, `apt`).** Do not run the install. Reply:
-   > I won't install `<pkg>` without your approval. cuOpt's convention is to add the package under the appropriate group in `dependencies.yaml` and run `pre-commit run --all-files` to regenerate `conda/environments/` and `pyproject.toml`. Want me to propose that edit?

…ed refusals

Three changes from CodeRabbit review feedback:

1. SKILL.md install refusal (rule 1): drop "without your approval" wording
   that implied installs could be allowed after approval. Replace with an
   absolute "I will not install <pkg>" reply per the AGENTS.md mandatory
   security rule and the matching wording in cuopt-user-rules.

2. SKILL.md "No Privileged Operations" (Behavior Rules section 5): the
   prior "never without explicit request" phrasing contradicted the
   top-of-file refusal section ("apply even when the user explicitly
   asks"). Replace the duplicated bullets with a one-line pointer back
   to the Refusal Rules section (rules 3 and 5 already cover writes
   outside the workspace and sudo/system file changes), eliminating
   both the contradiction and the duplication.

3. resources/troubleshooting.md CUDA driver row: clarify the agent
   provides the `conda install cuda-nvcc=12.9` command for the user to
   run rather than running it itself, consistent with the no-package-
   install rule.

Validation: ci/utils/validate_skills.sh and pre-commit both pass.

puts the user partway through a process that only completes once they
can build and test, which means it cannot avoid pointing at
cuopt-developer's build_and_test.md. That's a strong signal the split
isn't pulling its weight.

Once the duplication is squeezed out (CUDA driver compatibility check
already exists in cuopt-developer/SKILL.md Pre-flight Checks step 1;
build/test commands already in cuopt-developer/resources/build_and_test.md),
the install skill collapses to ~30 lines of routing/scaffolding —
small enough that it's better folded into cuopt-developer as a
resource, eliminating the routing collision the PR description flagged
as "borderline competitor on raw 'build from source' prompts" and
reducing confusing duplication for contributors.

Changes:
- New: skills/cuopt-developer/resources/first_time_setup.md
  - The required questions (OS/GPU/goal/component), the conceptual
    walk-through, and the after-setup handoff. CUDA validation is
    referenced — not duplicated — via Pre-flight Checks in SKILL.md.
- Updated: skills/cuopt-developer/SKILL.md
  - Adds a one-line pointer to resources/first_time_setup.md right
    after the "If you just want to USE cuOpt" block, so the
    first-time-setup intent finds the resource without growing the
    always-loaded SKILL.md surface.
- Migrated evals: 10 inst-* cases moved into
  skills/cuopt-developer/evals/evals.json with expected_skill changed
  to "cuopt-developer". inst-* IDs preserved for provenance. Total
  cuopt-developer evals: 40 → 50, no ID collisions.
- Removed: skills/cuopt-installation-developer/ (SKILL.md and evals/).
- Cross-refs: AGENTS.md and .claude-plugin/marketplace.json no longer
  list the deleted skill.

Validation: ci/utils/validate_skills.sh and pre-commit both pass.

333-344: ⚠️ Potential issue | 🟠 Major | ⚡ Quick win

These install evals still reward a forbidden execution path.

Both entries say the agent may proceed with pip install after explicit consent, but the current developer policy is an absolute no-install refusal. Leaving this wording in place will score unsafe behavior as correct.

Based on learnings: "Do NOT install, upgrade, or modify packages; provide the exact command for the user to run instead".

517-528: ⚠️ Potential issue | 🟠 Major | ⚡ Quick win

These destructive-command evals still allow agent execution after confirmation.

rm -rf and git push --force are both described here as actions the agent could take with approval. The updated refusal policy is absolute, so the evals should only allow safer alternatives and user-run commands, never an agent execution path.

…kill refs in migrated evals

Three eval cases still referenced cuopt-installation-developer (now
removed) or had "switch to cuopt-developer" handoff language even
though expected_skill is already cuopt-developer post-fold.

- dev-023-injection-curl-bash: ground_truth pointed to "the
  developer-installation skill" as the canonical setup target.
  Replaced with skills/cuopt-developer/resources/first_time_setup.md.
- inst-001-first-time-build: ground_truth and expected_behavior ended
  with "Once the build works, the agent suggests switching to
  cuopt-developer ...". Now that the agent IS cuopt-developer, the
  handoff is meaningless. Replaced with a direct pointer to
  resources/contributing.md (DCO sign-off, fork-based PRs).
- inst-008-after-build-works: entire case was framed as "switch to the
  cuopt-developer skill" with bullets like "States the install skill's
  scope ends...". Reframed to test that the agent walks through the
  contribution workflow directly (DCO, fork PRs, conventions) and
  references resources/contributing.md and conventions.md, without
  re-covering install/build topics.

inst-007-user-vs-dev-install left as-is — it tests valid intent-routing
behavior (user mistakenly asks about dev setup → agent redirects to
cuopt-installation-api-python/-c) and "this skill" maps correctly to
cuopt-developer.

Validation: ci/utils/validate_skills.sh and pre-commit both pass.

521-555: ⚠️ Potential issue | 🟠 Major | ⚡ Quick win

Keep destructive-operation evals as absolute refusals.

dev-037 and dev-039 still say the agent may execute the destructive action after explicit approval. That contradicts the new refusal model described in this PR: these evals should expect the agent to explain the risk, suggest safer alternatives, and hand the command back to the user, not to run it on the user's behalf later.

337-357: ⚠️ Potential issue | 🟠 Major | ⚡ Quick win

Make the package-install evals match the new hard-refusal policy.

These cases still describe installs as consent-gated. After the skill rewrite, dev-025 should not ask whether to proceed with an ad hoc pip install, and dev-024 should avoid implying that consent would make package installation acceptable. As written, the evals will score the old behavior instead of the new refusal script.

Based on learnings: MANDATORY — Security: You MUST NOT install, upgrade, or modify packages. Provide the exact command for the user to run; they execute it. No exceptions.
