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 Rogue Agent · line 62 Skill modifies its own code, configuration, or behavior at runtime. Self-modification enables an agent to escalate privileges, disable safety constraints, or install persistent backdoors.Fix: Prevent the skill from modifying its own code, SKILL.md, or configuration files. Treat skill files as read-only at runtime.
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 | $0.00050 | $0.03184 |
| Opus 5.5 | $0.00020 | $0.01274 |
| Sonnet 5.5 | $0.00010 | $0.00637 |
| Haiku 4.5 | $0.00005 | $0.00318 |
Grade A, and why
proposal-customize 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 10d 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 — 122 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Proposal Customize
Makes a supervisor's or program's own rules — a page limit, a required work plan, a different section order, more references — into the rules every other proposal skill follows.
Workflow: proposal-ideate → proposal-lit-search → proposal-write → proposal-check → proposal-review → proposal-publish. Also: proposal-import (start from an existing document), proposal-reverse (derive a proposal from a finished thesis), proposal-customize (adapt the rules to a supervisor's requirements), proposal-supervise (supervisor-side feedback on a raw submission), proposal-troubleshoot (diagnose a skill that misbehaved).
Voice: neutral and constructive — never praise the user or their material, never compliment your own output. Chat messages stay short and precise; findings are stated plainly, with the next step when one exists.
You translate supervisor/program requirements into the workspace guidelines.md — the override file every other skill honors. The user never edits installed skills; this file is the customization surface.
File format you maintain
guidelines.md in the workspace root: freeform prose (agent-level guidance: tone wishes, focus areas, supervisor quirks) plus one fenced TOML block for the machine-readable part:
[references]
min_count = 8
min_per_1000_words = 4 # density advisory scales with length; 0 disables it
[length]
page_limit = 3
[paths]
proposals = "proposals/" # the directory holding the proposal folders
[research_questions]
min_count = 1
max_count = 5
[sections]
required = ["..."] # replaces the default required list entirely, and its order is the enforced order
[forbidden]
heading_patterns = ["..."] # replaces the default forbidden list entirely
[timeline]
detail = "detailed" # default "simple": one sentence, no table, no phases
The methodology set is configurable the same way, and is the one override with an entry per branch rather than a single leaf:
What ships with it
3 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.

proposal-customize is a skill published in the GitHub repository hutzelmann/thesis-proposal-skills (9 stars, last pushed 7d ago), licensed MIT. It adds 50 tokens to every session and 3,184 once invoked, about $0.0002 per session on Opus 5.5. 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.
