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 | $0.02426 | $0.02426 |
| Opus 5 | $0.01213 | $0.01213 |
| Sonnet 5 | $0.00485 | $0.00485 |
| Haiku 4.5 | $0.00243 | $0.00243 |
Grade C, and why
agent-ebpf extension-value-audit.instructions.md scanned grade C with 1 finding 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.

Extension Value Audit
A verdict on whether the Claude Skills Manager VS Code extension
(claude-skill-deployer) is doing anything real in this project — grounded
in this project's own recorded telemetry plus what you, the agent running
this skill, can actually recall observing in your own session. This is not a
per-skill usage report (that's [[skill-usage-insights]]); it audits the
extension's own machinery: adaptive recommendations, task-focus, budget
gating, MCP-Force Mode, cross-agent sync, and its hooks pipeline.
Do not be diplomatic for its own sake. "This did nothing observable" is a legitimate, acceptable conclusion if the evidence says so. The point of this skill is to catch exactly the failure mode where a mechanism runs, writes data nobody reads, and nobody ever notices — that pattern has been the single most common finding in this extension's own reliability history. Padding a negative finding with hedging defeats the purpose.
1. What the extension claims to do
Judge everything below against these stated goals — not against "is telemetry present," which is a much lower bar:
- Adaptive skill installation/recommendation. Detects the project's stack and proposes/installs relevant skills, with a confidence score that's supposed to improve as it learns what gets accepted vs. ignored.
- Task-focus. Keeps only skills relevant to the current task loaded, auto-disabling the rest, so the agent isn't carrying dead weight in context.
- Budget/cost gating. Tracks spend and can auto-disable expensive ("high-tier") skills once a threshold is crossed.
- MCP-Force Mode. A security posture that routes file/shell access through an allow-listed MCP filesystem server instead of raw native tools.
- Cross-agent sync. Keeps skill sets and config consistent across Claude Code, Cursor, Kiro, and GitHub Copilot when a project uses more than one.
- Dashboards/visibility. A cost/usage dashboard, and (in newer versions)
a session-end summary — the extension's own attempt to make its telemetry
actually reach the user instead of sitting unread in a
.jsonlfile.
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.

agent-ebpf extension-value-audit.instructions.md is an instructions file published in the GitHub repository ourobx/agent-ebpf (1 stars, last pushed 9d ago), licensed MIT. It adds 2,426 tokens to every session, about $0.0121 per session on Opus 5. A static security scan graded it C with 1 finding (hidden instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
