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 39 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 | $0.00128 | $0.01541 |
| Opus 5.5 | $0.00051 | $0.00616 |
| Sonnet 5.5 | $0.00026 | $0.00308 |
| Haiku 4.5 | $0.00013 | $0.00154 |
Grade A, and why
resolve-section-ownership 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 1mo 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 — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Resolve Section Ownership
Always use the skill load-plain-reference to retrieve the ***plain syntax rules — but only if you haven't done so yet.
This is the ownership counterpart to break-down-func-spec. That skill splits one functional spec into several because it is too large; this one moves facts between sections because they are in the wrong place. The two are unrelated: a correctly placed spec can be too large, and a one-line bullet can be misplaced.
When to Use
- A bullet answers more than one of what is it, what does it do, how is it built, how is it tested.
- A requirement states a mechanism (retry, cache, token refresh, connection handling) but sits in
***functional specs***. - A
:UnitTests:fact sits in***test reqs***, or a:ConformanceTests:fact sits in***implementation reqs***— the generators read only their own section, so the fact is silently ignored today. - A functional spec describes an external system rather than the software being built.
- A whole file is being audited for placement.
When Not to Use
- The spec is correctly placed but too large →
analyze-if-func-spec-too-complex, thenbreak-down-func-spec. - Two specs contradict each other →
analyze-func-specs, thenresolve-spec-conflict. - The wording is merely verbose → trim per
concise-specs.md; no fact changes section.
Input
The bullet, section, or .plain file to resolve.
Workflow
- Read the full
.plainfile — every section, plus itsimportandrequireschains, so an existing home for a fact is visible before a new one is written. - Identify the target — one bullet, one section, or the whole file.
- Decompose each bullet into atomic facts. A clause joined by and, which, so that, or a comma often carries a second fact. Keep each fact in the author's own words for now; rewording comes at step 6.
- Route each fact by the Section ownership table in
module-structure.md. Where a fact resists the table, apply the question it encodes: would a caller of the finished software observe this? Yes →***functional specs***. No, it is how the result is reached →***implementation reqs***. It says what a term means →***definitions***. It shapes:ConformanceTests:→***test reqs***. - Split a fact that carries both a mechanism and its consequence. The consequence is observable and becomes the functional spec; the mechanism becomes the implementation req. "Sends the same idempotency key on every retry, so a retried write creates at most one record" is two facts, not one.
- Give each moved fact a subject that exists in the built system. A fact leaving a functional spec often loses its subject: name the component that owns the behavior, and add it to
***definitions***if it is not defined yet.:Implementation:is the whole codebase — use it only for a fact that holds everywhere. - Author each fact into its owning section with the right edit skill —
add-concept,add-implementation-requirement,add-test-requirement,add-acceptance-test. Never hand-author***functional specs***: a fact moving into that section goes throughadd-functional-spec, which runs the complexity and conflict analyzers for you. - Remove each fact from where it no longer belongs. If a bullet is left stating nothing observable, delete the bullet; do not leave a stub. Deleting the last bullet of a section deletes the section.
- Verify nothing was lost and nothing was duplicated. Walk every fact from the original text and confirm it appears in exactly one section. A fact that now reads as obvious in its new home is still a cut decision — make it deliberately, per
concise-specs.md. - Run
plain-healthcheck. Moving facts changes the renderable surface; do not finish on aFAIL. - Read the file again to confirm canonical section order (
***definitions***→***implementation reqs***→***test reqs***→***functional specs***), correct syntax, and that every referenced concept is still defined before use.
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.

resolve-section-ownership is a skill published in the GitHub repository plainlang/plain-forge (79 stars, last pushed yesterday), licensed MIT. It adds 128 tokens to every session and 1,541 once invoked, about $0.0005 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 2026-08-30.
