Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00090 | $0.04645 |
| Opus 5 | $0.00045 | $0.02322 |
| Sonnet 5 | $0.00018 | $0.00929 |
| Haiku 4.5 | $0.00009 | $0.00464 |
Grade A, and why
plugin-recommender scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 254 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Note: In external user install environments, the internal GHE org inventory and sister asset clusters are organization-specific examples from the original developer's environment. Adapt the core of this skill (multi-layer search + synergy evaluation + install support) to your own environment (see
## External User Environment Adaptation Path§).
plugin-recommender
Takes a task description as input, searches internal GHE, Claude Code marketplace, Codex marketplace, and external open-source ecosystems, then outputs a ranked list of suitable plugins and install commands. Ranking is quality-validation based — not source-origin based. Also reports duplicate installs and potential conflicts.
Activation Triggers
Activates on the following types of phrasing.
- Direct recommendation request: "Recommend a plugin", "What plugin should I use?", "Find a useful tool"
- Task-based implicit request: "I want to handle Jira tickets", "I need to visualize DB data", "I want to auto-generate API docs"
- Environment setup questions: "How do I integrate with Confluence?", "Set up plugins needed for a new project"
- Chained from sim-conductor (persona/simulation amplification): "Find a persona/simulation validation plugin", "Install stronger personas for the review". When invoked this way, scope the search to persona/simulation/review-oriented plugins (e.g., deep-insight) and return control to sim-conductor after install so the simulation can re-run with the installed personas — see
## Return Path§.
Processing Steps (Step 0 Pre-check + 5-Step)
Step 0: Search Pre-check — GitHub Token Auth Status
Before entering Step 2 multi-layer search, gh CLI auth status check is mandatory. Internal GHE + external GitHub auth are separate — if unauthenticated, guide user on how to generate and store tokens.
Run gh auth status. For full PAT setup commands and host-branching scripts, see SKILL_detail.md §Discovery-Bash.
External users (no internal GHE): skip internal GHE auth check — verify gh auth status for github.com only, then proceed to Step 1.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

plugin-recommender is a skill published in the GitHub repository chrono-meta/forge-harness (14 stars, last pushed 3d ago), licensed MIT. It adds 90 tokens to every session and 4,645 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
reconcile
Cross-reference a paper against the collection. Finds which cited papers are already collected, which are new leads, which collection papers cite this one, and reconciles all cross-references bidirectionally. Run on a single paper directory or use --all for the entire collection.
adjudicate
Systematically adjudicate disagreements across a paper collection. Produces ruthless verdicts on who was wrong, what supersedes what, and what the best current understanding is. Organized by topic clusters with actionable replacement values for implementation.
author-context
Create a propstore context for one paper with CEL assumptions, parameters, and perspective. Every claim extracted from the paper will reference this context. Required before extract-claims if the paper does not already have one.
author-rules
Author the DeLP rule artifacts (strict, defeasible, properdefeater, blockingdefeater) encoding a paper's stated argument structure. Runs after register-predicates.
extract-claims
Extract propositional claims from a paper directory into the propstore source branch using pks source propose-claim.
paper-retriever
Retrieve a scientific paper PDF given an arxiv URL, DOI, or paper title. Downloads to papers/ directory. Handles open-access retrieval (arxiv direct, Chrome print-to-pdf for publisher-direct HTML, Unpaywall, title-based open-repository search); for paywalled papers it hands off to whichever paper-retriever- access…
