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 | $0.00124 | $0.02814 |
| Opus 5.5 | $0.00050 | $0.01126 |
| Sonnet 5.5 | $0.00025 | $0.00563 |
| Haiku 4.5 | $0.00012 | $0.00281 |
Grade A, and why
pio-manager 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 25d 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.

PIO Manager (Mega-Skill)
This skill provides the mandatory 3-Tier Execution Architecture for interacting with PlatformIO builds, hardware flashing, and serial port logs. All agents MUST consult this skill before executing any target compilation.
The 3-Tier Execution Hierarchy
🟢 Tier 1 (Preferred): The pio-agent CLI
Run pio-agent as a normal shell command. It needs no server, starts nothing
that outlives the command, and returns structured JSON with --json.
- Compilation/Deployment/Analysis:
pio-agent build,pio-agent clean,pio-agent flash,pio-agent upload-fs,pio-agent project check,pio-agent test - Asynchronous Polling:
pio-agent task-status <id>,pio-agent task-cancel <id> - Hardware Claims:
pio-agent lock status,pio-agent port release --port <p> - Serial Monitor:
pio-agent monitor,pio-agent monitor-stop --port <p>,pio-agent logs query - Environment/Libraries:
pio-agent boards,pio-agent board-info --board <id>,pio-agent devices,pio-agent init,pio-agent lib search|install|uninstall|update|list - Diagnostics/Dashboard:
pio-agent dashboard,pio-agent project config,pio-agent project context,pio-agent system-info,pio-agent policy-status - Exact Targets:
pio-agent target-resolve - Bounded Monitoring:
pio-agent monitor-status,pio-agent logs capture,pio-agent monitor-health - Approval Status (read-only):
pio-agent approval-status <id>,pio-agent pending-approvals
Always pass --json when you intend to parse the result.
Reference: load references/cli-reference.md for exact flags.
Reading results: stdout, stderr and exit codes
There are three outcomes, not two, and conflating them makes failures look like silence:
| Outcome | Where the payload goes | Exit code |
|---|---|---|
| Succeeded | stdout, success: true (or a plain result) |
0 |
| Ran, but failed — a build with compiler errors, an unresolvable target | stdout, success: false |
non-zero |
| Could not run — bad arguments, policy refusal, a busy port | stderr, with errorType |
non-zero |

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.

pio-manager is a skill published in the GitHub repository jl-codes/platformio-mcp (54 stars, last pushed 16d ago), licensed MIT. It adds 124 tokens to every session and 2,814 once invoked, about $0.0005 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.
