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.

SkillSpector: 3 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 6 Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.

What it costs to keep this loaded
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 5.1 | $0.00090 | $0.04644 |
| Opus 5.5 | $0.00036 | $0.01858 |
| Sonnet 5.5 | $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 1mo 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 (30 stars, last pushed today), licensed MIT. It adds 90 tokens to every session and 4,644 once invoked, about $0.0004 per session on Opus 5.5. 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.
