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: 1 finding, up to high
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 →
- high Tool Misuse · line 128 Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.
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 | $0.00056 | $0.01948 |
| Opus 5 | $0.00028 | $0.00974 |
| Sonnet 5 | $0.00011 | $0.00390 |
| Haiku 4.5 | $0.00006 | $0.00195 |
Grade A, and why
session-crosslink 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 7d 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 — 142 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Session Crosslink
Response Format
Begin the first response to this skill invocation with the line:
Entire Session Crosslink:
followed by a blank line, then the content. Apply the header to the first response of the invocation only — not on follow-up turns and not on error / early-exit responses (no session resolved, no affected repos found).
STOP — Read these rules before doing ANYTHING
- Do NOT ask clarifying questions until the resolver/discovery steps have run. The session id and candidate repo list usually resolve from
entire session current --jsonplus what the user said. Only ask if both come back empty. - Do NOT run
entire session attachwithout showing the preview table first. The whole point of this skill is preview-then-confirm.attachamends the target repo's HEAD; previewing wrong means amending the wrong commit. - Always
cdinto the target repo before runningentire session attach. The CLI resolves the repo from cwd. Use onecd … && entire session attach …per call so each invocation hits the right repo.
Required CLI: entire 0.6.2+. No special flags needed — this skill works against the shipped CLI via cwd-scoped entire session attach.
Flow
Step 1: Resolve the session id
Try each strategy in order until one returns a session id.
Strategy A: Entire-enabled cwd.
entire session current --json
If the output is valid JSON and has a non-empty session_id, read session_id and agent and continue with those values. If the JSON parses but session_id is missing or empty, treat Strategy A as failed and fall through to B — don't proceed to attach with no session id.
Strategy B: Entire-enabled sibling repo. If the user named a repo that has Entire enabled (e.g. the foo repo), cd there and re-try entire session current --json. The session state lives wherever the session was tracked.
Strategy C: Runtime-specific transcript directory. If neither A nor B works, the session was never recorded by Entire and you must read it from the agent runtime:
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.

session-crosslink is a skill published in the GitHub repository entireio/skills (219 stars, last pushed yesterday), licensed MIT. It adds 56 tokens to every session and 1,948 once invoked, about $0.0003 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.
