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 | $0.00024 | $0.00548 |
| Opus 5 | $0.00012 | $0.00274 |
| Sonnet 5 | $0.00005 | $0.00110 |
| Haiku 4.5 | $0.00002 | $0.00055 |
Grade A, and why
validate-usercontext-instructions 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.
How it starts
The opening of the file, as written. The whole thing — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Validate User Context Instructions
Purpose
Validate user-context instruction files and produce structured reports with issues, recommendations, and a compliance score based on a deterministic scoring rubric.
When To Use
- Use this skill to validate
*_usercontext.instructions.mdfiles. - Use this skill before publishing or reusing a user-context file.
- Do not use this skill for project
AGENTS.md(project context) files.
How to Invoke
Load or attach this file's contents into your AI session to activate the workflow (paste, upload, or reference with #file:skills/validate-usercontext-instructions/SKILL.md in VS Code Copilot Chat). In Claude Projects, add it to project knowledge. See Invoking Skills in the README for full platform guidance.
Required Inputs
- Target file path.
- Expected spec version and required sections.
- Validation strictness expectations (if any).
Workflow
- Run validation phases from
references/phase-checks.md. - Check for
spec_versionfield in YAML frontmatter: flag as WARNING if absent (pre-existing files may predate this requirement); flag as WARNING if present but older than1.4.3. - Generate report using
references/report-contract.md. - Apply deterministic scoring from
references/scoring.md. - Classify findings into critical/warning/enhancement buckets.
- Produce implementation-ready recommendations.
Output Expectations
- A markdown validation report with phase-by-phase findings.
- Overall PASS/WARN/FAIL state and numeric score.
- Actionable fixes for critical and warning issues.
- Migration guidance when relevant.
- Report schema follows
references/report-contract.md. - Scoring and grade bands follow
references/scoring.md.
Resources
- Phase checks:
references/phase-checks.md - Report contract:
references/report-contract.md - Scoring model:
references/scoring.md - Example target:
../../usercontexts/sample_usercontext.instructions.md - Example report:
../../usercontexts/sample_usercontext.validation.md
What ships with it
4 files 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.

validate-usercontext-instructions is a skill published in the GitHub repository MSiccDev/ai-context-kit (12 stars, last pushed 4d ago), licensed MIT. It adds 24 tokens to every session and 548 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 2026-08-30.
