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 | $0.00032 | $0.01233 |
| Opus 5 | $0.00016 | $0.00616 |
| Sonnet 5 | $0.00006 | $0.00247 |
| Haiku 4.5 | $0.00003 | $0.00123 |
Grade A, and why
situate-what 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 — 123 lines — stays where its author put it; the contents beside it link to each section on GitHub.
What
The reader is disoriented. End that in five lines.
Read references/brief.md first — it defines the
five-line budget, what earns a line, the option lines, and the evidence
tiers that keep this cheap enough to ask casually.
User arguments: $ARGUMENTS
Context
Current branch — run this command and read the output:
git branch --show-current 2>/dev/null || echo "(detached HEAD)"
Ahead / behind trunk — run this command and read the output:
git rev-list --left-right --count "$(git symbolic-ref --short refs/remotes/origin/HEAD 2>/dev/null || echo origin/main)"...HEAD 2>/dev/null || echo "(no comparison available)"
Working tree — run this command and read the output:
git status --short 2>/dev/null | head -20 || echo "(unavailable)"
Commits since trunk — run this command and read the output:
TRUNK=$(git symbolic-ref --short refs/remotes/origin/HEAD 2>/dev/null || echo origin/main); BASE=$(git merge-base HEAD "$TRUNK" 2>/dev/null); if [ -n "$BASE" ]; then git log --no-merges --format='%h %s' "$BASE..HEAD" | head -15; elif git rev-parse --verify --quiet "$TRUNK" >/dev/null; then echo "(no merge-base with $TRUNK)"; else echo "(trunk $TRUNK not found)"; fi
Procedure
1. Read what was actually asked
Empty $ARGUMENTS means the whole situation: what this session has been
doing, and where the repository stands.
An argument narrows it to that subject, and narrowing is the point —
this skill the test failure answers about the test failure and
spends no lines on branch position.
2. Answer from the session first
The conversation is the highest-value evidence and the cheapest. When the confusion is about what just happened — a command that ran, a decision taken, why the work moved — the answer is already in context and needs no tools at all.
The context block above is local git, already gathered. It measures from trunk, which is the cheap approximation this command is built on — on a branch stacked over another branch that range carries the parent's commits too, so treat the count as approximate and say so rather than re-resolving the base for a five-line answer.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

situate-what is a skill published in the GitHub repository tony/skills (2 stars, last pushed 5d ago), licensed MIT. It adds 32 tokens to every session and 1,233 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 2026-09-03.
