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 | $0.00014 | $0.00288 |
| Opus 5 | $0.00007 | $0.00144 |
| Sonnet 5 | $0.00003 | $0.00058 |
| Haiku 4.5 | $0.00001 | $0.00029 |
Grade A, and why
missing-target 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 2d 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
missing-target
A negative fixture. The reference is well formed; there is simply no skill behind it.
What this fixture covers:
-
repo lintcode SK001, an error, and one of the two findings that makerepo lint --path .exit 1:SK001 [requires/missing-target]: Skill "requires/missing-target" requires "requires/no-such-skill", which does not exist in this repository. -
The distinction between a malformed reference and an unsatisfied one. A malformed reference is refused by the manifest parser and the skill does not resolve at all (see
requires/invalid-strict). This one parses, so the skill resolves normally and only the missing target is reported. -
Install is not blocked by it.
skillkeeper skill install requires/missing-targetprints the same sentence on standard error and then installs this skill anyway, exiting 0. A dependency that cannot be found is named, never fatal: the skill the user asked for is still what they get.
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.

missing-target is a skill published in the GitHub repository lorem-dev/skillkeeper-test-repo (2 stars, last pushed 9d ago), licensed MIT. It adds 14 tokens to every session and 288 once invoked, about $0.0001 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 2026-08-31.
