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 | $0.00064 | $0.00625 |
| Opus 5.5 | $0.00026 | $0.00250 |
| Sonnet 5.5 | $0.00013 | $0.00125 |
| Haiku 4.5 | $0.00006 | $0.00063 |
Grade A, and why
qalma-plugin-development 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.

Qalma Plugin Development
Build each plugin as a complete consumer-visible vertical slice while preserving the headless Qalma architecture.
Prepare
- Read plugin-contract.md.
- Read definition-of-done.md.
- Inspect
qalma-plugin.ts, the closest existing plugin, the ProseMirror registries, the public barrel, sandbox composition, and relevant tests. - Use
qalma-architecturefirst if the feature needs a new core extension point, public escape hatch, or library boundary.
Implement A Plugin
- Define the capability and separate engine behavior from consumer presentation.
- Prefer a proven ProseMirror package or primitive for editing semantics.
- Design Qalma-owned names and public options. Keep the raw engine contract private by default.
- Add the plugin under
libs/editor/src/lib/pluginsunless architecture criteria justify another location. - Contribute only the contract fields the feature needs: schema, commands, command states, shortcuts, or ProseMirror plugins.
- Export only consumer-facing symbols from
libs/editor/src/index.ts. - Configure the plugin in the sandbox TypeScript and compose its controls explicitly in the sandbox template. Never make the core auto-render buttons.
- Use
qalma-docs-syncto updateapps/docs, docs navigation, andlibs/editor/README.mdfor the public plugin surface. - Add focused tests for public behavior, configuration, invalid options, state, and keyboard behavior as applicable.
- Run the definition-of-done checks and stop every server started for testing.
Configurable Plugin Rules
- Define a Qalma-owned
...PluginOptionsinterface. - Export immutable default options when consumers benefit from knowing them.
- Use
createConfigurableQalmaPlugin. - Merge partial options with defaults.
- Validate resolved options early with actionable errors.
- Do not mutate the base plugin or previously configured instances.
- Do not expose every upstream option automatically; expose options that form a useful and supportable public contract.
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.

qalma-plugin-development is a skill published in the GitHub repository cdskill/qalma (10 stars, last pushed 2d ago), licensed MIT. It adds 64 tokens to every session and 625 once invoked, about $0.0003 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.

chronicle
Analyze Copilot session history for standup reports, usage tips, session search, and session reindexing. Use when the user asks for a standup, daily summary, usage tips, workflow recommendations, wants to search or find past sessions by keyword/file/PR, wants to reindex their session store, or asks about deleting…
update-skills
Create or update repository skills and instructions when major learnings are discovered during a session. Use when the user says "learn!", when a significant pattern or pitfall is identified, or when reusable domain knowledge should be captured for future sessions.
sync
Sync the current session branch with its upstream branch, or publish the current session branch to a remote. Use when the user asks to sync a branch, pull latest changes, rebase onto upstream, push current branch, publish branch, or set upstream.
generate-run-commands
Generate or modify run commands for the current session. Use when the user wants to set up or update run commands that appear in the session's Run button.
create-canvas
Create a Copilot extension canvas at user, workspace, or plugin scope.
create-skill
Create a reusable skill (SKILL.md) that packages a workflow.
