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 5.1 | $0.00080 | $0.00628 |
| Opus 5.5 | $0.00032 | $0.00251 |
| Sonnet 5.5 | $0.00016 | $0.00126 |
| Haiku 4.5 | $0.00008 | $0.00063 |
Grade A, and why
NorthwoodsMycelia scanned grade A 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 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.

NorthwoodsMycelia — Cross-Fleet Help (opt-in, v0.2 stub)
Calls the deployed Northwoods Pack Worker to post a help request or read open requests from the cross-fleet network.
v0.2 status: structural stub. The endpoints exist and enforce the opt-in contract, but cross-fleet wiring isn't built yet. Posts are acknowledged but not relayed. Full wiring lands in v0.3.
Workflow
- Read
pack.urlandauth.tokenfrom~/.claude/PAI/USER/SKILLCUSTOMIZATIONS/NorthwoodsPack/CONFIG.md. - Per-request opt-in REQUIRED: send header
X-Mycelia-Opt-In: trueon every call. Without it, the Worker returns 403.
Post a help request
curl -s -X POST "$PACK_URL/mycelia/ask" \
-H "Content-Type: application/json" \
-H "X-Pack-Token: $TOKEN" \
-H "X-Mycelia-Opt-In: true" \
-d '{
"question": "the question to ask the cross-fleet network",
"context": "optional context"
}'
Returns {acknowledged, note, received}.
List open requests
curl -s "$PACK_URL/mycelia/open" \
-H "X-Pack-Token: $TOKEN" \
-H "X-Mycelia-Opt-In: true"
Returns {open: [], note}. (v0.2 always returns empty array.)
Failure behavior
If the user has not explicitly opted in this request (no X-Mycelia-Opt-In: true header), the Worker returns 403 with a note explaining the opt-in requirement. Surface this to the user — they need to consciously enable.
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.

NorthwoodsMycelia is a skill published in the GitHub repository NorthwoodsSentinel/northwoods-pack (2 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 80 tokens to every session and 628 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
