fix(skills): strip duplicate description prefix + fix 15 over-limit descriptions

[immuhammadfurqan]

Summary

Fixes #46005 (the part that remains actionable after the YAML duplicate-prefix bug was resolved in main).

• agent/skill_utils.py: extract_skill_description() now defensively strips a spurious description: prefix from the parsed value — a regression guard against malformed YAML that duplicates the key (e.g. description: description: "actual text"). Prevents the silent truncation to broken strings like description: "Use when runni..." if the YAML generation bug ever reappears.

• 15 optional-skills/ SKILL.md files brought into compliance with the ≤60-char description standard from AGENTS.md. The affected skills had descriptions ranging from 164–414 characters that were being silently truncated to garbage by extract_skill_description(), breaking skill routing (the agent sees "Managed vector database for persiste..." instead of a useful description). Fixed skills: whisper, faiss, chroma, pinecone (×2), clip, llava, peft, flash-attention, nemo-curator, huggingface-tokenizers, guidance, honcho, mcporter, adversarial-ux-test.

• 9 unit tests added to tests/agent/test_skill_utils.py covering normal, edge-case, and regression paths for extract_skill_description() (previously untested).

Test plan

• scripts/run_tests.sh tests/agent/test_skill_utils.py — all 26 tests pass (17 existing + 9 new)
• Verify no skill description in the changed files exceeds 60 chars

Thanks for tightening the short descriptions; current main still truncates them in agent/skill_utils.py:777-778, and the targeted optional skills still carry long frontmatter values.

Problems

• agent/skill_utils.py:655 strips every value beginning with description:. The helper only receives a dictionary, so valid text such as Description: setup steps. is indistinguishable from the claimed malformed-YAML recovery case and would lose its prefix.
• optional-skills/research/pinecone/SKILL.md:2 adds a second pinecone skill while optional-skills/mlops/pinecone/SKILL.md:2 already uses that name. Official installs are keyed by bundle.name (hermes_cli/skills_hub.py:618-625), so the second skill is blocked unless forced.
• The new Pinecone skill adds two scripts but no tests/skills coverage; new skills require tests, and tests/skills/test_darwinian_evolver_skill.py:72-74 shows the lightweight syntax-check pattern.

Suggested changes

• Restrict the prefix handling to a parser-proven malformed-input path, or remove it.
• Rename the research skill to a distinct identifier and add frontmatter/script tests.

Automated hermes-sweeper review.

extract_skill_description() gets only a parsed dictionary, so this also strips a legitimate value such as description: "Description: setup steps.". Please remove this unconditional rewrite or limit it to a parser-proven malformed-YAML fallback path.

[teknium1]

This duplicates the existing official pinecone skill in optional-skills/mlops/pinecone. Official installs and lock entries are keyed by bundle.name, so users cannot install both normally. Please give this distinct skill a distinct identifier.

Thanks @teknium1! I've pushed an update addressing all three pieces of feedback:

Prefix strip I removed the unconditional description: prefix strip entirely, as the YAML parser bug was already fixed on main.
Distinct identifying name Renamed the new skill from pinecone to pinecone-research so it no longer conflicts with the mlops/pinecone skill. (Also shortened the mlops/pinecone description down to the <=60 char standard).
Tests & Scripts I've properly added two scripts (rag_pipeline.py and memory_manager.py) for the research skill, and added a test file (test_pinecone_research_skill.py) with 10 tests that parse the scripts via ast.parse(), check frontmatter validity, and verify naming. All tests pass locally.

Merged via PR #70512 — your reworked commit was cherry-picked onto current main with your authorship preserved in git history, plus a small follow-up adding the trailing periods the authoring standard requires.

Thanks for addressing all three review asks (dropping the stale prefix-strip, the pinecone-research rename, and the smoke tests) — the final shape landed cleanly. The 13 other over-limit optional-skill descriptions your original PR targeted were fixed in the broader cleanup PR #70531.
