Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

SkillSpector: 1 finding, 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 Rogue Agent · line 36 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
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 | $0.00048 | $0.00450 |
| Opus 5 | $0.00024 | $0.00225 |
| Sonnet 5 | $0.00010 | $0.00090 |
| Haiku 4.5 | $0.00005 | $0.00045 |
Grade A, and why
pi-observability-local-dev 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 8d 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.
What it actually says
Pi Observability Local Development
Use this workflow when iterating on packages/pi-observability and
the local dashboard at http://127.0.0.1:43190.
Workflow
-
Edit source files under
packages/pi-observability/src; do not edit generateddistdirectly. -
Validate focused changes first:
pnpm --filter @spences10/pi-observability run check:self pnpm --filter @spences10/pi-observability run test:self -
Rebuild the local dashboard/server output:
pnpm --filter @spences10/pi-observability run build:self -
Restart the server bound to port
43190:fuser -v -n tcp 43190 kill <PID> nohup node packages/pi-observability/dist/server.js > /tmp/pi-observability.log 2>&1 & tail -n 20 /tmp/pi-observability.log -
Refresh
http://127.0.0.1:43190and review the current UI against the requested behavior.
Notes
pnpm --filter ... exec pi-observability-servermay exit quickly in this repo; prefernode packages/pi-observability/dist/server.jsfor local review.- If
lsofis unavailable, usefuser -v -n tcp 43190to identify the port owner. - Keep the server PID in the final response when restarting it for the user.
- For Svelte edits, run LSP diagnostics and the Svelte autofixer before reporting completion.
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.

pi-observability-local-dev is a skill published in the GitHub repository spences10/my-pi (118 stars, last pushed today), licensed MIT. It adds 48 tokens to every session and 450 once invoked, about $0.0002 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.
