Clears every reference the new G7 lint flags, then makes it blocking so the
class cannot drift back. audit/engineering-agentic-2026-07 marked the
senior-ml-engineer half of this STILL-OPEN.
Deleted rather than updated:
- agent-designer/agent_evaluator.py's _define_cost_benchmarks() held
per-token prices for gpt-4, gpt-3.5-turbo and claude-3 at 2024 rates. The
result was assigned to self.cost_benchmarks and never read by anything, so
the method is gone. Cost analysis uses the cost_usd the caller supplies per
execution log, which is the only figure that can be accurate
Made model-agnostic, following the precedent already set by
senior-prompt-engineer/scripts/prompt_optimizer.py's --price-per-mtok:
- senior-ml-engineer SKILL.md and llm_integration_guide.md drop both 2024
price tables and the context-window table (which claimed GPT-4 = 8,192).
calculate_cost() takes rates as parameters; count_tokens() takes an
encoding name, since encodings outlive model IDs and
encoding_for_model() raises KeyError on anything unmapped
- OpenAIProvider loses its default model, so the caller must pass one
- llm-cost-optimizer's routing table names tiers, not models
Pinned to current IDs where an example genuinely needs one: SKILL_PIPELINE.md
(claude-opus-4-6 -> claude-opus-5), prompt-governance (claude-sonnet-4-5 ->
claude-sonnet-5), agent-designer README. Both dual-publish copies of the CAIO
pricing move together, so G4 stays green.
TEAM_STRUCTURE_GUIDE.md documented `prompt_optimizer.py --model gpt-4 --task
classification`. That contract no longer exists: there is no --task flag and
`prompt` is a required positional. Replaced with a runnable invocation.
Four references stay, with reasons in the allowlist: two litreview examples
where the retired model is the subject of the literature being reviewed, one
dated Computer Use citation, and the embedding benchmark already labelled a
2024 snapshot.

Resolves#712 and #714.
Claude Code's plugin spec (code.claude.com/docs/en/plugins-reference) requires
"All paths must be relative to the plugin root and start with ./". CC 2.1.144+
rejects the bare "skills" form with `Validation errors: skills: Invalid input`,
breaking plugin installs from this repo.
Changes:
- 47 plugin.json manifests migrated from "skills": "skills" → ["./skills"]
(canonical post-CC 2.1.144 form, also accepts string "./skills")
- scripts/check_plugin_json.py rewritten to enforce the live spec:
* Hard-fails on non-"./"-prefixed strings (except the legacy "skills" literal)
* Hard-fails on empty strings/arrays and non-string array entries
* Emits WARN (non-fatal) on the legacy "skills" literal as a safety net
for copied templates — the WARN tolerance can be removed later
* Tested against all four canonical forms + 3 garbage forms
- CLAUDE.md §5 rewritten to document the live spec, including the historical
context of the v2.1.107 → v2.1.144 regression window that's now closed
- 15 stale broken symlinks under .gemini/skills/ removed (orphans from older
reorgs that the sync script didn't prune because its cleanup is disabled)
Verification:
- scripts/check_plugin_json.py --all → 0 FAIL, 0 WARN, exit 0 (69 files OK)
- pytest tests/ → 2103 passed
- find . -type l ! -exec test -e {} \; → 0 broken symlinks
- Live spec forms tested: ["./"], ["./skills"], "./skills", ["./a","./b"] all pass
- Garbage forms rejected: bare "./", empty array, non-string entries, plain strings
Claude Code 2.1.133+ rejects "skills": "./skills" with a "Path escapes
plugin directory" warning, even though ./skills resolves to a valid
subdirectory inside the plugin root. Per the upstream docs example, the
correct value is "skills" (no ./ prefix), which works across all CC
versions and other tools (Codex, Gemini CLI, etc.).
Applied to all 47 plugin.json files that used "./skills"; updated
CLAUDE.md ClawHub publishing constraints to document the new convention
and reference the issue.
Claude Code v2.1.126 rejects "skills": ["./"] (array form) at runtime
with the same "Path escapes plugin directory: ./" error as the bare
string form, despite the official plugins reference docs explicitly
showing ["./"] as a valid example. `claude plugin validate` accepts it,
so the bug is in the runtime loader, not the manifest validator.
The proven workaround (already used for self-improving-agent in #536)
is to follow the canonical layout:
<plugin>/
├── .claude-plugin/plugin.json skills: "./skills"
└── skills/<plugin-name>/
├── SKILL.md
├── scripts/
├── references/
└── ...
Applied to 21 single-skill plugins:
- engineering-team/a11y-audit, google-workspace-cli, snowflake-development
- engineering/behuman, code-tour, data-quality-auditor, demo-video,
docker-development, helm-chart-builder, karpathy-coder, llm-cost-optimizer,
llm-wiki, prompt-governance, statistical-analyst, terraform-patterns
- finance/business-investment-advisor
- marketing-skill/video-content-strategist
- product-team/agile-product-owner, apple-hig-expert, code-to-prd,
research-summarizer
Moved with each SKILL.md: scripts/, references/, assets/, templates/,
expected_outputs/. Kept at plugin root (per Claude Code requirements):
agents/, commands/, hooks/, settings.json, README.md.
Bumped patch version on each restructured plugin so /plugin update
picks up the new layout.
Refs #539
PR #587 fixed `"skills": "./"` in 35 plugin.json files but did not bump
versions. Claude Code uses version as the cache key — same version string
means /plugin update is a no-op and users keep loading the cached
plugin.json with the broken path. The /plugin UI shows "1 error" on
every plugin from this marketplace because the installed cache is stale.
Per the official version-management docs:
> If you set `version` in `plugin.json`, you must bump it every time
> you want users to receive changes. Pushing new commits alone is not
> enough.
Bump every plugin.json by one patch using max(plugin_version,
marketplace_version) as the base so no version moves backward. Sync the
new versions back into .claude-plugin/marketplace.json.
After this lands, users run `/plugin marketplace update claude-code-skills`
followed by `/plugin update --all` to pull the fixed manifests.
Claude Code v2.1.107+ rejects bare "skills": "./" with "Path escapes
plugin directory: ./". This blocks every plugin in the marketplace from
loading. Replace with the layout-appropriate form per the official
plugins reference:
- Single-skill plugin (SKILL.md at root):
"skills": ["./"] array form (per docs example)
- Plugin with skills/ subdir:
"skills": "./skills" standard subdir layout
- Multi-skill domain plugin (skills are subfolders at root):
"skills": ["./sub1", "./sub2"] explicit list of skill dirs
The multi-skill case omits "./" from the array so the index SKILL.md
at the plugin root does not register as a skill — that would create
a redundant `marketing-skills:marketing-skills` namespace.
Verified by running `claude plugin validate` against all 35 manifests.
Closes#539
Updated the skill description to emphasize proactive usage and clarified triggers for cost optimization. Enhanced the context and steps for cost auditing, optimization, and architecture design.
Each skill is now individually installable:
- llm-cost-optimizer
- prompt-governance
- business-investment-advisor
- video-content-strategist
